Answer:
<u>Given</u>: base = 10.4ft, height = 12.5
Area of octagon = 8(1/2 × b × h)
- 8(1/2 × 10.4 × 12.5)
- 520ft²
Volume of pool = 520ft² × 3ft
Now, 1 cubic ft takes 7.5 gallons to fill.
Therefore, 1560 cubic ft takes,
So, <u>Correct choice</u> - [D] 11,700.
Answer:
C) 20, 4
Step-by-step explanation:
X = 5y
2x + 5y = 60
substitute in 5y for x: 2(5y) + 5y = 60
10y + 5y = 60
15y = 60
y = 4
x = 5y
x = 5(4) = 20
Answer:
I believe the answer should be 4.1 units.
Question:
If all the edges of prism A are multiplied by 5 to create prism B. The volume of prism B will be __________ times the volume of prism A?
* 5
* 125
* 50
* 25
Answer:
* 5 times.
Step-by-step explanation:
Let us represent all the edges of prism A as = X
Prism B = All the edges of Prism A × 5
Prism B = X × 5
= 5X
Let's assume the prism is a cube
Volume of a Prism(cube) = L × W × H
Volume of Prism A = L × W × H
Volume of Prism B = 5 (L × W × H)
Therefore, The volume of prism B will be 5 times the volume of prism A
