Answer:
Step-by-step explanation:
To find the circumference of a circle, we use the formula:
Circumference = 2 * π * radius
Let's calculate the circumferences for the given options
1. Circumference = 2 * 3.14 * 53 ≈ 333.64 cm
2. Circumference = 2 * 3.14 * 227 ≈ 1428.28 cm
3. Circumference = 2 * 3.14 * 20 ≈ 125.6 cm
4. Circumference = 2 * 3.14 * 27 ≈ 169.56 cm
now, rounding each value to the nearest unit , we get
1. Circumference ≈ 334 cm
2. Circumference ≈ 1428 cm
3. Circumference ≈ 126 cm
4. Circumference ≈ 170 cm

Answer:
Translate ABC to the right 2 units and down 4 units.
Step-by-step explanation:
Focus on how you count the squares, look at the blue triangle and then at the pink one. You count the A first to the right so it gets you the answer of 2 units to the right now count the same A and proceed to locate where the A' is so you count 4 squares as you get down to the A'. I hope this helped you understand (-_-;")

A pair of equations is shown below:
y = 7x − 8
y = 5x − 2
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution.
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer
Answer:
x = 3
(3, 13)
Step-by-step explanation:
Given equations:
y = 7x − 8y = 5x − 2Part ASolve by substitution:
⇒ y = y
⇒ 7x - 8 = 5x - 2
Subtract 5x from both sides:
⇒ 7x - 8 - 5x = 5x - 2 - 5x
⇒ 2x - 8 = - 2
Add 8 to both sides:
⇒ 2x - 8 + 8 = - 2 + 8
⇒ 2x = 6
Divide both sides by 2:
⇒ 2x ÷ 2 = 6 ÷ 2
⇒ x = 3
Part BTo find the y-value of the point of intersection, substitute the found value of x (from part A) into one of the equations:
⇒ y = 7(3) - 8
⇒ y = 21 - 8
⇒ y = 13
Therefore, the point at which the lines intersect is (3, 13)

Answer:
F. 1080
Step-by-step explanation:
Just like any shape, we get to do base x height! If you haven't located the base yet it's the right triangles. So first we have to find the area of the triangle and then multiply by the height (20). Lets find the area of the triangle first. To get the area you do (length x width)/2. 9*12/2=54. Now 54*20=1080

Answer: Mary makes $1160, Steven makes $142.50
Step-by-step explanation:
Facts
MARY
8% commision on everything she sells
She sells a car for $14,500
The first question about Mary asks how much commision she makes. To find that, lets find 8% of 14,500
8% of 14,500= 0.08x14,500= 1160
Therefore, Mary makes $1,160 in commision.
STEVEN
Facts
He makes 15% in commision for the supplies he sells
He sells $950 in supplies
Money made =?
15% of 950=0.15x950=$142.50

Enter your answer in the box.
Answer:
1872 ft.²
Step-by-step explanation:
First lets figure out all of the easy shapes:
The bottom one: 8 * 7 = 56
The one on the left: 5 * 8 = 40
The one of top: 8 * 3 = 24
The slanted rectangle: 5 * 8 = 40
The small rectangle below that : 2 * 8 = 16
Now we just have the polygon facing toward us. It can be broken up into 2 parts:
The lower half: 2 * 7 = 14
Imagine a line going from the top of the line marked "2" straight across to the other side. That is the bottom half. Now we are left with a trapezoid. The formula for the area of a trapezoid is as follows:
A = ((a + b) / 2) * h
What this means is that we had the top and bottom of the figure, divide that by 2, and multiply it by the height. That can be shown here:
(3 + 7) / 2 = 5 * 3 = 15
15 is the area of the trapezoid. Now we can combine that with 14 to get the total area of the polygon:
14 + 15 = 29
Then do the same again for the other identical figure
14 + 15 = 29
Now we have all the areas of our shapes. Let's add them up:
56 + 40 + 24 + 40 + 16 + 29 + 29 = 234
234 is the total surface area of the box. Since there are 8 boxes, multiply this by 8 to get your final answer:
234 * 8 = 1872 ft.²
Don't forget to include units!
The solution is : 1872 ft.² of the new material is needed to build all 8 containers.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

56 + 40 + 24 + 40 + 16 + 29 + 29 = 234
234 is the total surface area of the box.
Since there are 8 boxes, multiply this by 8 to get your final answer:
234 * 8 = 1872 ft.²
