Answer:
Dimensions are nine by nine, the diagonal is the square root of 162.
Step-by-step explanation:
The resulting square will have the same width as before, with a height to match, (9,9) The diagonal can be found using the pathagyreon theorom.
9^2 + 9^2 = x^2.
The dimensions of the square would be nine by nine, the diagonal is the square root of 162.
The square will have the same width as before, with a height to match, (9,9)
The diagonal can be found using the Pythagorean theory.
9^2 + 9^2 = x^2.

The angle of elevation to a nearby tree from a point on the ground is measured to be 66^{\circ} ∘ . How tall is the tree if the point on the ground is 68 feet from the tree? Round your answer to the nearest tenth of a foot if necessary.
By comparing with a right triangle, we will see that the height of the tree is 62.12ft
How tall is the tree?
We can compare the situation with a right triangle. Such that the hypotenuse measures 68 ft, and an angle measures 66°.
We want to get the height of the tree, which would be the opposite cathetus, then we can use the relation:
Sin(a) = (opposite cathetus)/hypotenuse.
Sin(66°) = H/68ft
Tan(66°)*68ft = H = 62.12ft
The height of the tree is 62.12ft

you have to substitute the equation. sub y=1x-1 into the other equation.
Answer:
-y = x-1 is a fairly simple equation at least with real integers.
I hope to help you understand the process of solving it so you can apply the thinking to increasingly difficult equations. If this equation is difficult for you, I will try to explain it simply.
let's try a simple trick. If you want to solve for y, then it's helpful to remove the negative from it.
that means you need to do the same thing to the x side, but since x is already positive it needs to change to -x to balance things out.
the equation now reads y = -x+1 because we have reversed the negative and positive values on both sides of the equation.
I hope this helps simplify the thinking behind solving an equation of this nature. The two previous answers above this one are both correct, but may be just a tad more complex than you need at this moment.

Let's first look only at the numerator: 5x^2 - 5
Consider this question: What do both terms have in common?
The answer is 5, both terms contain a 5, so we can factor it out.
5(x^2 - 1)
Now let's look at the denominator, considering the same question: 3x^2 + 3x
This time, both terms contain a 3 and an x.
3x(x^2 + 1)
Now we are here: [ 5(x^2 - 1) ] / [ 3x(x + 1) ]
In the numerator, the binomial factors out into (x + 1)(x - 1). There is also an (x + 1) in the denominator, so those to binomials cancel out. That leaves us with the following expression:
5(x - 1) / 3x

Simplify: 3[(7 - 5) 2 + (20 - 19) 2] + 14
Answer:
32
Step-by-step explanation:
We first solve everything in the parenthesis. So: (7 -5) = 2 and (20 - 19) = 1. Now we change the equation:
3[(2)2 +(1)2] + 14
Then we multiply inside the brackets: 2 x 2 = 4 and 1 x 2 = 2. So the equation now looks like this:
3[ 4 + 2] + 14
Now we add:
3{6} + 14:
We multiply:
18 + 14
Finaly we add again:

What percentage of 3hrs is 45 mins
Answer:
25%
Step-by-step explanation:
First convert 3 hours into minutes by multiplying 3 x 60 min/hr. This is 180 minutes. To find the percentage, divide 45 minutes by 180 minutes and then multiply by 100.
45/180=0.25x100 = 25%
The time 45 minutes is 75 percentage of 3 hours
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the percentage be represented as A
Now , the equation will be
The time be represented as p = 45 minutes
The value of p = 3/4 hours
The value of q = 3 hours
So , the percentage is A = ( p/q ) x 100
Substituting the values in the equation , we get
The percentage A = ( 3/4 ) / 3 x 100
On simplifying the equation , we get
The percentage A = ( 3/12 ) x 100
The percentage A = ( 1/4 ) x 100
The percentage A = 25 %
Hence , the percentage is 25 %

the mode of the six numbers is 8
Jenny arranges her cards so that the numbers are in order of size.

(a) For the remaining four cards, write on each line a number that could be on the card.
Mean is the ratio of the sum of data to the ample size. The remaining four cards that could be on the card are 8, 8, 16 and 22
Measure of dispersionMean is the ratio of the sum of data to the ample size. Median is the middle number after rearrangement while the mode is the most occurring number.
Given the sequence of numbers in order of size as 5, _, _, _, _ 24
Since 2 number falls in the middle and the median is 14, hence:
x +y/2 = 14
Since 8 is the mode, we can assume x = 8 in order to determine "y" as shown
8+y/2 = 14
8+y = 28
y = 16
The sequence of numbers will become 5, 8, 8, 16, _ 24 (8 was repeated twice being the mode)
The last unknown number can then be any value between 16 and 24. Using 22 as the last unknown value, the remaining four cards that could be on the card are 8, 8, 16 and 22

Answer:

Step-by-step explanation
i have a triangle area calculator lol..
The length of the base of the triangle is B = 8.5 inches
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the area of the triangle be A = 25.5 inches²
Let the height of the triangle be H = 6 inches
Let the base of the triangle be B
Now , area of the triangle = ( 1/2 ) x Length x Base
On simplifying , we get
25.5 = ( 1/2 ) x ( 6 ) x ( B )
On simplifying , we get
3B = 25.5
Divide by 3 on both sides , we get
B = 8.5 inches
Hence , the base of triangle is B = 8.5 inches
