Given parameters:
Area of pool = 154ft²
Unknown:
The circumference or perimeter of the pool = ?
Solution:
The amount of fencing needed for the pool is the same as the circumference of the pool or the perimeter of the pool.
To solve this problem, we need to find the radius from the given area.
Area of a circle = π r²
154 = π r²
r² = [tex]\frac{154}{3.142}[/tex] = 49
r = 7ft
Now the circumference of a circle = 2 π r
= 2 x π x 7
= 44ft
The circumference of the circle is 44ft

Bastian was able to map triangle ABC onto triangle A'B'C' using a reflection, rotation, and a dilation. Then Bastian concluded that he was able to map triangle ABC onto triangle A'B'C' using a sequence of rigid transformations and dilations, so the triangles are similar. What error did Bastian make in his conclusion?
Bastian used a rotation, so the triangles aren't similar.
Bastian used a combination of similarity transformations, which can produce a non-similar result.
There is no error. This is a correct conclusion.
Bastian used a dilation, which does not preserve similarity.

Find the slope of the line passing through each of the following pairs of points.
(0, -8), (0,4)
Answer:
The slope is undefined
Step-by-step explanation:
You can find the slope by doing change in y/change in x.
Y changed by 12 units while x changed by 0.
12/0 is undefined, so the slope is as well (on a graph, the line would be vertical)
0 or undefined or infinity
Step by step explanation:
slope = y2 - y1 / x2 - x1
= 4 + 8 / 0 + 0
= 12 / 0
= 0

Answer:
The first one is option one and the second one is option two
Step-by-step explanation:
3/0.8 = z/5.6
Solve for z
3 / 0.8 = z / 5.6
To find z, we need to isolate z. How can we do this? Right now, we know z / 5.6 is equal to 3 / 0.8.
To isolate z, we should multiply by 5.6 on each side.This will cancel the divide by 5.6 or the 1/5.6 on the right side to isolate z!
(3 × 5.6) / 0.8 = z
16.8 / 0.8 = z
All we have to is simplify!
z = 21

Answer:
angles 3 and 4 are a linear pair
Step-by-step explanation:
3 and 4 are a linear pair because the both make up 180 degrees together.
A conjecture and the flowchart proof used to prove the conjecture are shown.
Given: A B C D is a parallelogram. Prove: Angle 1 is supplementary to angle 3. Art: Parallelogram A B C D. Ray D B is drawn and is extended past vertex B. The ray forms an interior angles A D B and D B C and an exterior angle labeled as 3, adjacent to angle D B C. Angle A D B is labeled as 1, and angle D B C is labeled as 2.
Drag an expression or phrase to each box to complete the proof.
Answer:
1. Definition of parallelogram
Step-by-step explanation:
1. Definition of parallelogram
2. Angle Congruence Postulate
3. m<2 + m<3 =180
4. m<1 + m<3 =180
5. Definition of supplementary
∠1 is supplementary to ∠3 by the Definition of supplementary angles
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line.
Prove: Angle 1 is supplementary to angle 3.
Given information as; ABCD is a parallelogram.
Proof:
∠1 = ∠ADB
∠2 = ∠DBC
∠3 = the exterior angle adjacent to angle D B C.
Statement Reason
∠2 is supplementary to ∠3 Linear pairs
m∠2+m∠3=180° Definition of supplementary angles
m<1 + m<3 = 180 Alternative interior angles
m∠1+m∠3=180° Substitute property of equality
∠1 is supplementary to ∠3 Definition of supplementary angles
Therefore, we can conclude that ∠1 is supplementary to ∠3 by the Definition of supplementary angles.

9 increased by the quantity of b added to 10
Answer:
19b + 10
Step-by-step explanation:
Here, we want to increase 9 by the quantity of b added to 10.
We proceed as follows;
9 increased by quantity of b is 9 + b
This added to 10 would be 9 + b + 10 = 19b + 10
Where is the shading in the graph of the quadratic inequality y > -22 + 6x + 3? Why?
Answer:
Check Graph below
Step-by-step explanation:
y > -22 + 6x + 3
Add -22 and 3.
y > 6x - 19
Use the slope-intercept form to find the slope and y-intercept.
Slope: 6
y-intercept: (0,-19)
Graph a dashed line, then shade the area above the boundary line since y is greater than 6x − 19 .
y > 6x - 19

1 When the product of 4 and a number x is added to 12, the result is 16. What is the difference between x and 8?
Answer:
x = 1
Step-by-step explanation:
12 + 4 x = 16
Subtract 12 from both sides.
4x = 4
Divide 4 on both sides.
x = 1
