Find the height of the object next to the triangle using the similarity of the triangle.
Answers
Answer: If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

Square KLMN with vertices K(0,2), L(1,8), M(7,7), and N(6, 1): 270 counterclockwise about the orgin
Answers
Note: Consider we need to find the vertices of the image.
Given:
Square KLMN with vertices K(0,2), L(1,8), M(7,7), and N(6, 1).
It rotates 270 counterclockwise about the origin.
To find:
The vertices of the image after rotation.
Solution:
If a figure rotates 270 counterclockwise about the origin, then the rule of rotation is defined as
[tex](x,y)\to (y,-x)[/tex]
Using this rule, we get
[tex]K(0,2)\to K'(2,0)[/tex]
[tex]L(1,8)\to L'(8,-1)[/tex]
[tex]M(7,7)\to M'(7,-7)[/tex]
[tex]N(6,1)\to N'(1,-6)[/tex]
Therefore, the vertices of the image are K'(2,0), L'(8,-1), M'(7,-7) and N'(1,-6).

Step-by-step explanation:
This is correct.
hope this helps ;D
Answer:
All real square roots of 121 is +11 and -11.
When you square root something, you take the positive and negative of the number, so the square root of 121 would be 11 and -11.
When you do 11 times 11, you get 121 and when you do -11 times -11, you get 121 as well, this is why we do the negative as well.

If C is the midpoint of BD, what is the coordinate of point C if point B is at 0?
Answers
Answer:
13
Step-by-step explanation:
Given:
BC = 2x + 7
CD = x + 10
Coordinate of point B = 0
Required:
Coordinate of point C
SOLUTION:
Since C is the midpoint of BD, therefore:
BC = CD
2x + 7 = x + 10 (substitution)
Collect like terms
2x - x = -7 + 10
x = 3
BC = 2x + 7
Plug in the value of x
BC = 2(3) + 7 = 6 + 7
BC = 13
Thus, the coordinate of point C would be a distance of 13 units away from the coordinate of point B.
Since the coordinate of B is 0, 13 units away from 0, would be 13.
Therefore, the coordinate of point C = 13
The coordinate of point C if If C is the midpoint of BD will be (0, 13)
From the given diagram, if C is the midpoint of BD, hence;
BC + CD + BD
Given the following parameters
BC = 2x + 7
CD = x + 10
Since C is the midpoint of BD, hence BC = CD
2x + 7 = x + 10
2x-x = 10 - 7
x = 3
Get the measure of BC:
BC = 2x + 7
BC = 2(3) + 7
BC = 13 = CD
Hence the coordinate of point C will be (0, 13)

Choose the slope and y-intercept that
correspond with the graph.
Answers
Answer:
Y-intercept: -1Slope: -1/3Step-by-step explanation:
The y-intercept is the point where the line crosses the y axis (horizontal line in graphs). We can clearly see that the y-intercept is -1, since the line intersects the y axis at y = -1.
Ok, now for the slope, we will use this equation, where m is the slope we wish to find.
m = rise/run where rise is the change in y and run is the change in x.
To determine the rise and run, we need two coordinate pairs.
9, -4 and 0, -1 will do
Note: The coordinate pairs are x, y, but slope is y/x, it is important that we do not become confused.
Now, we will subtract one y from the other and then do the same for the x's. It is important that we use the same order for the x's as we do for the y's, in order for the answer to be valid.
Y -4 - -1 = -3
X 9 - 0 = 9
Slope is -3/9 or -1/3

Answers
Answer:
[tex]3\sqrt{3} + 72[/tex]
Step-by-step explanation:
I attached an image to aid the understanding of the question.
Looking at the image, we see that the 8 shaded parts are congruent, as affirmed in the question as well. And we are told that T = 3, this implies that the area of the square with T as it's side is 9ft². Since all the 8 squares are congruenrt, it means each square has its area to be 9. Therefore, the total area of the 8 shaded squares will be:
[tex]9 \times 8 = 72ft^{2}[/tex]
It remains the area of the shaded square with side S.
From the question, we have the following ratio:
[tex]\frac{9}{S} = \frac{S}{T}[\tex]
But
[tex]\frac{9}{S} = \frac{S}{3}[\tex]
Multiplying through by 3S we have
27 = S² and this gives:
[tex]S = \sqrt{27} = 3\sqrt{3}[/tex]
I did not add ± because length is always positive, so the case of negative is eliminated.
Now the areas of S is [tex]3\sqrt{3}[/tex]
Therefore, the total area of the shaded squares is
[tex]3\sqrt{3} + 72[/tex]
Answer:
17
Step-by-step explanation:
We are given that [tex]$\frac{9}{\text{S}}=\frac{\text{S}}{\text{T}}=3.$\[\frac{9}{\text{S}}=3\][/tex]gives us S=3, so[tex]\[\frac{\text{S}}{\text{T}}=3\][/tex]gives us T=1. There are 8 shaded squares with side length [tex]$\text{T}$[/tex] and there is 1 shaded square with side length [tex]$\text{S},$[/tex] so the total shaded area is [tex]$8\cdot(1\cdot1)+1\cdot(3\cdot3)=8+9=\boxed{17}.$[/tex]

Answers
Answer:
10 students/van
48 students/bus
Step-by-step explanation:
(a) 13v+5b = 370
(b) 12v+10b = 600
(a) - (b)
v -5b = -230
v = 5b-230
12(5b-230) + 10b = 600
60b+10b -2760=600
70b=3360
7b=336
b=48
v = 5(48) - 230 = 10
v = 10
Let's check
12(10) +10(48) = 600

A small town has two local high schools. High School A currently has 850 students and is projected to grow by 35 students each year.

Write an equation for each situation, in terms of t,t, and determine after how many years, t,t, the number of students in both high schools would be the same.
Answers
An equation for each situation, in terms of t, is y = 850e^35t and
y = 700e^70t
The required equation will be in the form y = Ae^kt
where:
k is the growth constantA represents the number of students in High School A in t years.B represents the number of students in High School B after t years.If High School A currently has 850 students and is projected to grow by 35 students each year, hence;
A = 850k = 35 (growth factor)Substituting into the formula, we will have:
y = 850e^35t
If High School B currently has 700 students and is projected to grow by 60 students each year, hence;
A = 700k = 60 (growth factor)Substituting into the formula, we will have:
y = 700e^70t

Which number would make this statement true?

9.1
8.91

8.99
Answers
Answer:
8.09
9.1 is obviously greater than 8.9, when you compare the numbers.
And the other numbers are all 8 in the ones place (to the left of the decimal). So, you have to look at the number in the tenths place (to the right of the decimal). 8.09 has a "0" in the tenths place, & 8.9 has a "9" in the tenths place, making 8.09 less than 8.9.
If you compared the 2 remaining numbers 8.91 & 8.99, they would both be greater, because since they all have the same number in the tenths place, you have to move on to comparing the next number, which would be in the hundreths place (2 digits to the right of the decimal).

The value of the expression 5³ is 125.
We have,
The concept used in calculating the value of 5 raised to the power of 3 is exponentiation.
In mathematics, exponentiation is an operation that involves raising a base number to a certain power.
The base number (in this case, 5) is multiplied by itself repeatedly, where the number of times it is multiplied is determined by the exponent (in this case, 3).
When we raise 5 to the power of 3, we can interpret it as multiplying 5 by itself three times:
5³ = 5 x 5 x 5 = 125
So, the concept of exponentiation allows us to quickly calculate the result of multiplying a number by itself multiple times, where the exponent indicates the number of repetitions.
Thus,
The value of the expression 5³ is 125.
