Answer:
45 because 188 divided by 4 is 47 but subtract 2 bc there is not a sprinkler at either end and you get 45
A) $355 + $18x = $514 + $15x
B) $355 + $18x = $514 + $15x
355 -355 + 18x = 514 -355 + 15x
18x = 159 + 15x
18x-15x=159+15x-15x
3x = 159
3x/3=159/3
x = 53
C) $355 + $18(53) = $1309
$514 + $15(53)= $1309
D) You can check your answer by taking what x equals and plugging back into the original formula of $355+$18x=$514+$15x. Then solve making sure the left side equals the right side.
$355+$18x=$514+$15x
$355 + $18(53)=$514 + $15(53)
$1309 = $1309
Answer:
The pyramid with the greater volume has 5in^3 more sand
Step-by-step explanation:
Given
Pyramid A
-- Base Area
--- height
Pyramid B
See attachment for pyramids
The volume of a square pyramid is:
First, calculate the volume of pyramid A
Next, the volume of pyramid B
To calculate how much more sand the greater pyramid has, we simply calculate the absolute difference (d) between their volumes

Answer:
- 15 2/9
Step-by-step explanation:
3⁻² = 1 / 3² = 1/9
(½)⁻⁴ = 1 / (½)⁴ = 1 / (1/16) = 16
³√(8/27) = ³√8 / ³√27 = 2/3
1/9 - 16 + 2/3 = 1/9 - 144/9 + 6/9 = - 137/9 = - 15 2/9
