Answer:
Below
Step-by-step explanation:
To find surface area, you can just find the area of each side and add them up!
11 ft x 9 ft x 2 = 198 ft^2 (this is the surface area of the front and back)
12 ft x 9 ft x 2 = 216 ft^2 (this is the surface area of the sides)
12 ft x 11 ft x 2 = 264 ft^2 (this is the surface area of the top and bottom)
Surface area = 198 + 216 + 264
= 678 ft^2
Hope this helps! Best of luck <3
Answer:
24, 40
Step-by-step explanation:
The area of a triangle is given by the formula
where
b is the length of the base
h is the length of the height
For the 1st triangle here, we have:
b = 6 is the base
h = 8 is the height
So, the area of the triangle is
For the 2nd triangle here, we have:
b = 8 is the base
h = 10 is the height
So, the area of the triangle is
Answer is D
A is translating up
B is translating down
C is multiplying so no
Answer in fraction form: x = 55/4
Answer in decimal form: x = 13.75
Both forms are equivalent, but they say it in a slightly different way.
===========================================================
Work Shown:
AC/QY = CD/YW
(x+5)/15 = 5/4
4(x+5) = 15*5
4x+20 = 75
4x = 75-20
4x = 55
x = 55/4
x = 13.75
------------
Explanations:
- The first step is possible because the polygons are similar. Similar figures have their corresponding sides be in the same proportion or ratio. Note how side AC has the double red angle (at point A) and a single red angle (point C). The side QY has the same idea in the same order. This is why AC corresponds to QY. The ratio AC/QY is the same as CD/YW.
- In the second step, I plugged in the expressions that the diagram shows. This is the substitution property.
- On step 3, I cross multiplied. The general format is A/B = C/D cross multiplies to A*D = B*C.
