Answer: 1) 162.5 2) 261.1 3) 11.5%
<u>Step-by-step explanation:</u>
is: means equals
of: means multiplication
what: means variable
percent: means divide by 100 (move the decimal 2 places to the left
1.
52 is 32% of what number
52 = .32x
<u>÷ .32 </u> <u>÷ .32 </u>
162.5 = x
2.
what number is 70% of 373
x = .70 × 373
x = 261.1
3.
84 is what percent of 732
84 = x ÷ 100 × 732
<u>÷732 </u> <u> ÷ 732 </u>
0.115 = x ÷ 100
<u>×100 </u> <u> × 100 </u>
11.5% = x
The power used in each bolt is 125.
1000- the power together
Divided by the 8 - lights together
So you would do 1000 divided by 8 to get the power of an individual light, which is 125. (1000 ➗ 8 = 125.)
You could even check ur answer by 8 x 125 equals 1000
Answer:
2.13 ft x 2.13 ft x 2.66 ft
Step-by-step explanation:
If W is the width of the square base, and H is the height, then:
12 = W²H
The cost of the crate is:
C = 8W² + 2W² + 4(4WH)
C = 10W² + 16WH
Solve for H in the first equation:
H = 12 / W²
Substitute into the second equation:
C = 10W² + 16W (12 / W²)
C = 10W² + 192 / W
Take the derivative with respect to W.
dC/dW = 20W − 192 / W²
Set to 0 and solve:
0 = 20W − 192 / W²
20W = 192 / W²
20W³ = 192
5W³ = 48
W = ∛(48/5)
W ≈ 2.13 ft
Find H:
H = 12 / W²
H ≈ 2.66 ft
