Answer:
Let’s call the base of the triangle b and its height h. The area of a triangle is given by the formula A = 1/2 * b * h.
If Suki says that the area of the triangle is 12 cm², then we can write:
12 = 1/2 * b * h
Similarly, if Emilia says that the area of the triangle is 10 cm², then we can write:
10 = 1/2 * b * h
We can solve for one of the variables in terms of the other by dividing both sides of each equation by 1/2:
b * h = 24
b * h = 20
Now we have two equations with two variables. We can solve for one variable in terms of the other by dividing both sides of one equation by the other:
(b * h) / (b * h) = 24 / 20
1 = 6/5
This is a contradiction, so there is no solution that satisfies both equations.
Step-by-step explanation:
Complete the equation so it has infinitely many solutions. 4(x-4)= 4x +
guys how do i do this
Answer: To have infinitely many solutions, the equation must simplify to a true statement, such as 0=0.
So, let's simplify the given equation:
4(x-4) = 4x + ?
We need to choose a value for the constant on the right-hand side so that the equation simplifies to a true statement.
We can start by distributing the 4 on the left-hand side:
4x - 16 = 4x + ?
Now we can see that the 4x terms cancel out, leaving:
-16 = ?
We can choose any value for the constant on the right-hand side, and the equation will be true. For example:
-16 = -16
So the complete equation with infinitely many solutions is:
4(x-4) = 4x - 16
Step-by-step explanation:
The point (-1, 5) ___ (is or is not) on the parabola because the point is ___ units from the directrix and ___ units from the focus.
The point (3, 3) (is or is not) on the parabola because the point is ___ units from the directrix and ___ units from the focus
The point (5,5) (is or is not) on the parabola because the point is ___ units from the directrix and ___ units from the focus
For the point (5, 4) to the directrix, the distance to the directrix is equal to the distance to the focus. For the other points on the list, the distance to the directrix is equal to the distance to the focus. The distance to the directrix is equal to the distance to the focus, we can conclude that (-1, 5) is on the parabola.
What is parabola ?A perfect, U-shaped curve is referred to by the term parabola in mathematics. It is described as the collection of all plane points that are equidistant from a focus and a fixed broadband (the directrix). The point where the parabola's curve changes direction is known as its vertex, and the line that runs through it and is perpendicular toward the directrix is known as its axis of symmetry. The behavior of electromagnetic waves, projectile motion, reflector and antenna forms, and other real-world phenomena are frequently modelled using parabolas.
To determine whether a point is on a parabola with a given focus and directrix, we can use the definition of a parabola: a parabola is the set of all points that are equidistant to the focus and the directrix.
In this case, the focus is the point (0, 2) and the directrix is the line y = -2.
Let's first consider the point (5, 4). We can find the distance from this point to the directrix by finding the distance from the point to the line. The formula for the distance from a point (x1, y1) to a line [tex]Ax + By + C = 0[/tex] is:
[tex]|Ax1 + By1 + C| / \sqrt(A^2 + B^2)[/tex]
In this case, A = 0, B = 1, and C = -2, so the equation of the directrix is y = -2, which can be written as [tex]0x + 1y - 2 = 0.[/tex] Plugging in (5, 4), we get:
[tex]|0(5) + 1(4) - 2| / \sqrt(0^2 + 1^2) = 6[/tex]
So the distance from (5, 4) to the directrix is 6.
Next, we can find the distance from (5, 4) to the focus (0, 2):
[tex]\sqrt((5-0)^2 + (4-2)^2) = \sqrt(29)[/tex]
Since the distance from (5, 4) to the directrix is not equal to the distance from (5, 4) to the focus, we can conclude that (5, 4) is not on the parabola.
We can repeat this process for each point on the list. For the point (-1, 5), we get:
Distance to directrix: |-1 - 2| / 1 = 3
Distance to focus: [tex]\sqrt((-1-0)^2 + (5-2)^2) = \sqrt(26)[/tex]
Since the distance to the directrix is equal to the distance to the focus, we can conclude that (-1, 5) is on the parabola.
Similarly, we can check the other points on the list and find that the points (4, 3), (2, 1), (1, -2), (2, -1), (4, -3), and (5, -4) are also on the parabola. The points (3, 5), (6, 7), (8, 0), and (0, 8) are not on the parabola.

Triangle PQR is a right triangle. P(-6,9) Q(-1,-1) R(-9,5) what is the area of triangle PQR
The area of triangle PQR is 25/2 * √(5).
Describe Triangle?In geometry, a triangle is a two-dimensional shape with three straight sides and three angles. It is one of the basic shapes in geometry and has many important properties and applications.
The sum of the interior angles of a triangle is always 180 degrees, and the exterior angles sum to 360 degrees. The three sides of a triangle can be classified according to their lengths and their angles.
To find the area of triangle PQR, we can use the formula:
Area = (1/2) * base * height
where the base and height are the lengths of two sides of the right triangle that meet at a 90-degree angle.
We can use the distance formula to find the lengths of the sides of triangle PQR:
PQ = √[(x_Q - x_P)² + (y_Q - y_P)²] = √[(-1 - (-6))² + ((-1) - 9)²] = √[25 + 100] = 5√(5)
PR = √[(x_R - x_P)² + (y_R - y_P)²] = √[(-9 - (-6))² + (5 - 9)²] = √[9 + 16] = 5
QR = √[(x_R - x_Q)² + (y_R - y_Q)²] = √[(-9 - (-1))² + (5 - (-1))²] = √[64 + 36] = 2√20) = 4√(5)
Since triangle PQR is a right triangle, the base and height are PQ and PR, respectively. Therefore, the area of triangle PQR is:
Area = (1/2) * PQ * PR = (1/2) * 5√(5) * 5 = 25/2 * √(5)
So the area of triangle PQR is 25/2 * √(5).

If P(x,y) is the preimage Of a point, then it’s image after a dilation centered at the origin (0,0) with the scale factor k is the point P'
If a point's preimage is P(x, y), then its image after a dilation with a scale factor of k and centered at the origin (0, 0) is P'(kx, ky).
What is Pre picture of a point?The set of all points in a function's domain that correspond to a given point in the range is known as the preimage of a point in mathematics.
Formally, let f be a function that goes from a set A to a set B, and let y be a point in B. The preimage of y is the set of all points x in A where f(x) = y, or the set of all points in the domain that the function maps to the given point in the range.
If the preimage of the point P has facilitates (x, y), and the expansion focused at the beginning with a scale component of k is applied, then the directions of the picture point P' can be tracked down utilizing the accompanying recipe:
The x- and y-coordinates of P' are determined by multiplying the corresponding coordinates of the preimage point P by the scale factor k; consequently, the coordinates of the image point P' following the dilation with the origin centered on k would be (kx, ky).

The percentage growth in computer specialists during 1960-1970 was 200% for both sexes.
What is the percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
To calculate the percentage growth, we need to know the initial number of computer specialists and the number of computer specialists after the growth period.
Let's assume that in 1960, there were 1000 computer specialists, and in 1970, there were 3000 computer specialists.
The growth in computer specialists during this period can be calculated as follows:
Growth = Final number - Initial number
Growth = 3000 - 1000
Growth = 2000
To calculate the percentage growth, we divide the growth by the initial number and multiply by 100:
Percentage Growth = (Growth / Initial number) * 100
Percentage Growth = (2000 / 1000) * 100
Percentage Growth = 200%
Therefore, the percentage growth in computer specialists during 1960-1970 was 200% for both sexes.

Kenji just went down the slide at the playground. He walks 5 feet to get from the end of the slide back to the ladder. Then he climbs 8 feet to the top of the slide again. How long is the slide? If necessary, round to the nearest tenth.
Answer: Let's call the length of the slide "x". From the problem, we know that Kenji walks 5 feet after he slides down and climbs 8 feet to get to the top of the slide again. This means that the total vertical distance he traveled (height of the slide) is equal to 5 + 8 = 13 feet.
Using the Pythagorean theorem, we can find the length of the slide:
x^2 = 13^2 + h^2
where h is the height of the slide.
We know that h = 13 feet, so we can substitute that into the equation:
x^2 = 13^2 + 13^2
x^2 = 338
x ≈ 18.4 feet
Therefore, the length of the slide is approximately 18.4 feet. Rounded to the nearest tenth, this is 18.4 feet.

how many revolutions will a car wheel of diameter 24 in. make as the car travels a distance of one mile? (round your answer to the nearest whole number.)
The car wheel will make approximately 840 revolutions as the car travels a distance of one mile.
To calculate the number of revolutions that a car wheel of diameter 24 in. will make as the car travels a distance of one mile, we need to use the formula:
number of revolutions = distance traveled / distance per revolution
The distance traveled is given in miles, and we need to convert the diameter of the wheel, given in inches, to the distance per revolution in miles.
The diameter of the wheel is 24 in., which means the radius is 12 in. The distance per revolution is equal to the circumference of the wheel, which is given by the formula:
circumference = 2 * pi * radius
Substituting the values, we get:
circumference = 2 * pi * 12 in. = 75.4 in.
To convert this to miles, we divide by 63,360 inches per mile:
distance per revolution = 75.4 in. / 63,360 in./mi = 0.00119 mi/rev
Now, we can calculate the number of revolutions as:
number of revolutions = 1 mi / 0.00119 mi/rev ≈ 840 revolutions

At a school
Number of boys:number of girls=11:9
There are 124 more boys to girls
Work out the total number of student at the school
From given ratio of boys and girls, the total number of students at the school is 1240.
What exactly is a ratio?
A ratio is a comparison of two quantities or values by division. It is commonly used to express the relationship between two numbers, such as the ratio of the number of boys to the number of girls in a classroom.
The ratio of two numbers a and b can be expressed as a/b or as the fraction a:b. For example, if there are 20 boys and 30 girls in a classroom, the ratio of boys to girls is 20/30, which can be simplified to 2/3 or written as the fraction 2:3.
Now,
Let's represent the number of boys as 11x and the number of girls as 9x, where x is a common factor.
From the given information, we know that:
11x = 9x + 124
Simplifying
11x - 9x = 124
2x = 124
x = 62
Now,
Number of boys = 11x = 11(62) = 682
Number of girls = 9x = 9(62) = 558
Therefore, the total number of students at the school is:
Total number of students = Number of boys + Number of girls = 682 + 558 = 1240

2. Ben is making two separate investments with his $2,400
inheritance.
He will invest $1,500 in Investment R which pays 2.75%
annual simple interest
He will invest $900 in Investment S which pays 2.75%
interest compounded annually
a. What is the difference between the balance of the two
investments after 8 years?
b. What is the difference between the interest earned of the two
investments after 8 years?
c. Which of the two had the better return on investment?
Step-by-step explanation:
We can use the simple interest formula:
R = P(1 + rt)
where R is the balance, P is the principal, r is the interest rate, and t is the time.
For Investment R, we have:
R = 1,500(1 + 0.0275*8)
R = 1,980
For Investment S, we can use the formula:
R = P(1 + r)^t
R = 900(1 + 0.0275)^8
R = 1,116.92
a. The difference between the balance of the two investments after 8 years is:
1,980 - 1,116.92 = 863.08
b. The interest earned for Investment R is:
I = Prt
I = 1,500*0.0275*8
I = 330
For Investment S, we can calculate the interest using:
I = R - P
I = 1,116.92 - 900
I = 216.92
The difference between the interest earned on the two investments is:
330 - 216.92 = 113.08
c. To compare the return on investment, we can use the concept of compound interest.
For Investment R, the total value after 8 years is:
R = 1,500(1 + 0.0275*8)
R = 1,980
For Investment S, we can calculate the effective annual rate:
EAR = (1 + r/n)^n - 1
EAR = (1 + 0.0275/1)^1 - 1
EAR = 0.0275
The total value after 8 years is:
R = 900(1 + 0.0275)^8
R = 1,116.92
The return on investment for Investment R is:
ROI = (1 + r/n)^nt - 1
ROI = (1 + 0.0275/1)^1*8 - 1
ROI = 0.2229
The return on investment for Investment S is:
ROI = (1 + EAR)^t - 1
ROI = (1 + 0.0275)^8 - 1
ROI = 0.2329
Therefore, Investment S had the better return on investment.

The minimum value of multiplication of AxB is 245,376.72, which is obtained when A = 450 (rounded down from 495) and B = 545 (rounded up from 537.03).
What is multiplication?Calculating the sum of two or more numbers is the procedure of multiplication. It is expressed as "a multiplied by b" when two numbers, let's say "a" and "b," are multiplied. Multiplication in mathematics is essentially just adding a number continuously in relation to another number.
The given values are:
A = 900 rounded to the nearest 10 = 900
B = 90.7 rounded to 1 decimal place = 90.7
We need to find the minimum value of AxB.
Multiplying A and B directly, we get:
AxB = 900 x 90.7 = 81,630
To find the minimum value of AxB, we can use the concept of AM-GM inequality which states that for two positive real numbers a and b, their arithmetic mean (AM) is greater than or equal to their geometric mean (GM):
AM ≥ GM
or
(a+b)/2 ≥ √(ab)
Applying this to our values of A and B, we get:
(A+B)/2 ≥ √(AxB)
Substituting the given values of A and B, we get:
(900 + 90.7)/2 ≥ √(AxB)
Simplifying this, we get:
495.35 ≥ √(AxB)
Squaring both sides, we get:
245,376.72 ≥ AxB
Therefore, the minimum value of multiplication of AxB is 245,376.72, which is obtained when A = 450 (rounded down from 495) and B = 545 (rounded up from 537.03).

The recursive and explicit formulae of the given arithmetic expression are:
Recursive formular = [tex]a_{n+1} = a_{n-13}[/tex]
Explicit formular is Tn = 75 - 13n
Describe the differences between an explicit formula and a recursive formula.You can determine the value of any term in a series by using an explicit formula. The integers are divided into the natural numbers, which are 1, 2, 3, 4, and so on. If you know the value of the (n-1)th term in a sequence, you may use a recursive formula to determine the value of the nth term in the sequence. Recursive formulas give the value of a specific phrase depending on the previous term, whereas explicit formulas give the value of a specific term based on the position.
Given:
a1 = 52
a2 = 75 = 52 - 13 = a1 - 13
Recursive formular = [tex]a_{n+1} = a_{n-13}[/tex]
a = 52, d = -13
F(11) = a + (n - 1)d = 52 + (n - 1)-13 = 52 - 13n + 13 = 75 - 13n
Explicit formular is Tn = 75 - 13n

The arithmetic sequence has a common difference of 23, recursive rule of this sequence is xₙ = [tex]x_{n-1}[/tex] + 23 and explicit rule is xₙ = 23n + 29. The 11th term is 282.
What is an arithmetic sequence?An arithmetic sequence is a mathematical progression in which each term is generated by adding a constant value to the preceding term, with the exception of the first term. This constant value is known as the common difference, and it governs the pattern of the sequence. There are two types of arithmetic sequences, one is an increasing sequence and the other is a decreasing sequence. Increasing sequence is obtained if the common difference is a positive number. Decreasing sequence is obtained if the common difference is a negative number.
The general format of the recursive rule is xₙ = [tex]x_{n-1}[/tex] + d, where xₙ is the nth term, [tex]x_{n-1}[/tex] is the (n-1)th term and d is the common difference of the arithmetic sequence.
In the given sequence x₁ = 52 and x₂ = 75
Common difference can be calculated by subtracting first term from second term = x₂ - x₁ = 75 - 52 = 23
Hence recursive rule for this sequence is xₙ = [tex]x_{n-1}[/tex] + 23
The general format of explicit rule is xₙ = x₁ + (n-1) × d.
For this sequence it is xₙ = x₁ + (n-1) × 23 = 52 + 23n - 23 = 23n + 29
To find f(11) we can use the explicit rule
f(11) = 23 × 11 + 29 = 282

After answering the presented question, we can conclude that As a expression result, the laptop costs $2500 without GST.
what is expression ?An expression in mathematics is a collection of representations, digits, and conglomerates that mimic a statistical correlation or regularity. A real number, a mutable, or a combination of the two can be used as an expression. Mathematical operators include addition, subtraction, rapid spread, division, and exponentiation. Expressions are often used in arithmetic, mathematics, and form. They are employed in the representation of mathematical formulas, the solving of equations, and the simplification of mathematical relationships.
To get the laptop's price without GST, divide the inclusive price by (1 + GST rate as a decimal).
As a result, the laptop's price without GST can be estimated as follows:
Price excluding GST = Price including GST / (1 + GST rate as a decimal)
Price excluding GST = 2675 / (1 + 0.07)
Without GST, the price is $2500.
As a result, the laptop costs $2500 without GST.
