7. (a) A homeowner wishes to replace the three identical steps leading to her front door with a ramp. Each step is 10 cm high and 35 cm long. Find the length of the ramp. Give your answer correct to one decimal place.
Answer: To replace the three steps with a ramp, the height of the ramp must be equal to the total height of the steps. Since each step is 10 cm high, the total height of the three steps is 3 * 10 = 30 cm.
The length of the ramp must be equal to the length of the steps, since the ramp is replacing them. Since each step is 35 cm long, the total length of the three steps is 3 * 35 = 105 cm.
So the length of the ramp to replace the three steps leading to the front door is 105 cm, correct to one decimal place.

Solve the inequality:
4-3x<16
Answer:
x > -4
Step-by-step explanation:
This is solved just like as if it was an equation. Its a two-step equation (inequality) The only thing that's different is with an inequality, it is imperative that you flip the inequality symbol if you multiply or divide by a negative number.
Here, we'll subtract 4 from both sides. Then divide by -3 on both sides. Flip! the < to a >.
see image.
x > -4.
Step-by-step explanation:1. Write the expression.[tex]4-3x < 16[/tex]
2. Subtract "4" from both sides of the equation.[tex]4-3x-4 < 16-4\\ \\-3x < 12[/tex]
3. Divide both sides by "-3" and switch the inequality symbol.[tex]\frac{-3x}{-3} < \frac{12}{-3} \\ \\x > -4[/tex]
Important. See that we switched the inequality symbol from "<" to ">", and this is because the symbol of the coefficient of variable "x" changed from negative to positive when it was divided by "-3". This rule will always be true, any time the symbol of the variable changed, the inequality symbol changes.
4. Verify.If x >-4 is the correct answer, then substituting x by "-4" in the inequation should make the inequation return the same value on both sides of the inequality symbol (>).
[tex]4-3(-4) > 16\\ \\4-(-12) > 16\\ \\4+12 > 16\\ \\16 > 16[/tex]
That's correct! x > -4 is the correct answer.

Since 9/16 is the closest to 8/16 or around 1/2 in this case, it'd be about 1/2. I hope this helps!
Solve the triangle. Round to the nearest tenth.
39°
16
84°
B
Answer:
A. m<C = 57 degrees, a = 12, b = 19
Step-by-step explanation:
First we can start by calculating Angle C by using the rule that all interior angles of a triangle always add to 180 degrees:
180 - (39+84) = C
180 - 123 = C
C = 57
Now let's calculate side a. We can do this by using the sin rule: [tex]\frac{sin A}{a}=\frac{sin C}{c}[/tex]
According to the diagram we know that Angle A is 39 degrees, Angle C is 57 degrees, and side c is 16 so we can substitute these values into the formula and solve:
[tex]\frac{sin39}{a} =\frac{sin 57}{16} \\\\\frac{0.629320}{a} =\frac{0.838671}{16}\\\\0.629320=0.052417a\\0.629320/0.052417=a\\a= 12[/tex]
We can use the same method to solve for side b:
[tex]\frac{sin84}{b} =0.052417 \\0.994522=0.052417b\\0.994522/0.052417=b\\b= 19[/tex]
We now have the following values:
Angle C = 57 degrees, a = 12, b = 19
We can now see that A/Number 1 is the correct option.
Hope this helped!

In a class of 23 students, 9 play an instrument and 7 play a sport. There are 3 students who play an instrument and also play a sport. What is the probability that a student does not play an instrument given that they play a sport?
Answer:
There are 23 students
-- 9 students play neither sport
-- therefore, 23 - 9 = 14 students play at least one of the two sports; some play both sports.
Inclusive or: the probability will be: 14 / 23 that a student chosen at random will play at least one of the two sports.
Exclusive or: we need to first find how many students play both sports.
Since 14 persons play sports and since 7 play basketball and 12 play baseball, this requires 7 + 12 = 19 students.
Subtracting 19 - 14 = 5 give the number of students who play both sports.
If we eliminate these 5 persons as well as the 9 who play neither sport, we have to eliminate 5 + 9 = 14 persons.
This gives 23 - 14 = 9 persons who play only one of the two sports.
The probability will be: 9/23 play a sport, but only one sport.
Step-by-step explanation:
The probability that a student does not play an instrument given that they play a sport is 6/7 or approximately 0.857.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To find the probability that a student does not play an instrument given that they play a sport, we need to use conditional probability.
Let A be the event that a student plays a sport and B be the event that a student plays an instrument.
We want to find P(not B | A), which is the probability that a student does not play an instrument given that they play a sport.
We know that,
P(A) = 7/23, P(B) = 9/23, and P(A and B) = 3/23.
Using the formula for conditional probability, we have:
P(not B | A) = P(A and not B) / P(A)
We can find P(A and not B) by using the fact that,
P(A and B) = P(B) - P(A and not B).
P(A and not B)
= P(B) - P(A and B)
= 9/23 - 3/23
= 6/23
Substituting into the formula, we get:
P(not B | A) = (6/23) / (7/23) = 6/7
Therefore,
The probability that a student does not play an instrument given that they play a sport is 6/7 or approximately 0.857.

Step-by-step explanation:
If 7 tickets equals 56
56/7=8
Answer:
8 Dollars
Step-by-step explanation:
If the question you are asking is how much is a ticket, if 7 tickets cost a total of 56 dollars, then the answer is 8. This is because you would divide the total cost bu how many there are, which would look like 56 / 7 = 8.
The measures of the angles of a triangle are shown in the figure below. Solve for x.
(5x-17)®
(7x-3)
56°
The measurement of three angles in the triangle are 43°, 81°, 56°.
What are the angles of a triangle?A triangle's interior angles always add up to 180°, whereas its exterior angles are equal to the sum of the two interior angles that are not adjacent to it.
Given three angles,
∠A = (5x - 17)°
∠B = (7x - 3)°
∠C = 56°
We know that in a triangle ∠A + ∠B + ∠C = 180°
By substituting values,
(5x - 17) + (7x - 3) + 56 = 180
12x -20 + 56 = 180
12 x + 36 = 180
12x = 180 - 36
12x = 144
x = 144/12
x = 12
By substituting values of x we get,
∠A = (5x - 17)°
= 5 x 12 - 17
= 60 - 17
= 43
∠A = 43°
∠B = (7x - 3)°
= 7 x 12 - 3
= 84 - 3
= 81
∠B = 81°

Step-by-step explanation:
The average age of Elliot, Miya and Cara is 4 years more than the average
age of Elliot and Miya.
Cara is 9 years older than Elliot.
Four years ago, Elliot was double the age of Miya.
Work out the ages of Elliot, Miya and Cara.
Answer:
Elliot = 16 years old
Miya = 10 years old
Cara = 25 years old
Step-by-step explanation:
Define the variables:
x = Elliot's agey = Miya's agez = Cara's ageThe average age of Elliot, Miya and Cara is 4 years more than the average age of Elliot and Miya:
[tex]\implies \dfrac{x+y+z}{3}=\dfrac{x+y}{2}+4[/tex]
[tex]\implies \dfrac{x+y+z}{3}=\dfrac{x+y+8}{2}[/tex]
[tex]\implies 2(x+y+z)=3(x+y+8)[/tex]
[tex]\implies 2x+2y+2z=3x+3y+24[/tex]
[tex]\implies 2z=x+y+24[/tex]
[tex]\implies x=2z-y-24[/tex]
Cara is 9 years older than Elliot:
[tex]\implies z = x + 9[/tex]
Four years ago, Elliot was double the age of Miya:
[tex]\implies (x - 4) = 2(y - 4)[/tex]
[tex]\implies x - 4 = 2y-8[/tex]
[tex]\implies x +4 = 2y[/tex]
[tex]\implies y=\dfrac{1}{2}x +2[/tex]
Substitute the equations for z and y into the equation for x and solve for x:
[tex]\implies x=2z-y-24[/tex]
[tex]\implies x=2(x+9)-\left(\dfrac{1}{2}x +2\right)-24[/tex]
[tex]\implies x=\dfrac{3}{2}x-8[/tex]
[tex]\implies \dfrac{1}{2}x=8[/tex]
[tex]\implies x=16[/tex]
Substitute the found value of x into the equation for z and solve for z:
[tex]\implies z = 16 + 9[/tex]
[tex]\implies z = 25[/tex]
Substitute the found value of x into the equation for y and solve for y:
[tex]\implies y=\dfrac{1}{2}(16) +2[/tex]
[tex]\implies y=8+2[/tex]
[tex]\implies y=10[/tex]
Therefore, the ages of Elliot, Miya and Cara are:

did the siblings meet? Explain how you know.
The siblings met at the point (4,7). This can be determined by looking at the graph and seeing that the point (4,7) is the only point with an x-coordinate of 4 and a y-coordinate of 7.
What is coordinate?Coordinate refers to the pair of numbers used to identify the position of a particular point on a graph, map, or other two-dimensional plane. Each coordinate consists of an x-coordinate and a y-coordinate that indicate the horizontal and vertical position of the point, respectively. Coordinates can be used to plot points, draw shapes, and determine distances between points. For example, the coordinates (4, 7) would tell you that the point is located four units to the right and seven units up from the origin point. Coordinates can also be used to describe the location of a point in three-dimensional space, with the addition of a z-coordinate.
