Answer:
either -8 6/7 or about -8.86
Step-by-step explanation:
Considering that the trench is modeled by a rectangular prism, the volume that was removed is 1776 cubic feet.
The volume of a <u>rectangular prism of length l, width w and height h</u> is given by:

In this problem, we want the measures in feet, and considering that 1 feet is 12 inches:
- The length is of 102' 6''(102 feet and 6 inches), hence
.
- The width is of 5' 4'', hence
.
- The depth(height) is of 3' 3'', hence
.
Then:

The volume that was removed is 1776 cubic feet.

Answer:
(1, 2) and (-1, -2)
Step-by-step explanation:
Since y = 2x, the first blank tells you
2x = 2
x = 1
____
Since the variables are squared, a negative solution is as good as a positive solution, so x = -1 and y = -2 will also work.
Answer:
$= 15p=250
Step-by-step explanation:
So lets say 15 per guest is represented at p so $= 15p+250
Given:
Grocery store: 8 ounces of blueberries = $2.80
Farmer's market : 14 ounces of blueberries = $4.20
1 pound = 16 ounces.
Unit rate: per ounce
Grocery store: $2.80 ÷ 8 oz = $0.35 per ounce
Farmer's market: $4.20 ÷ 14 oz = $0.30 per ounce
Unit rate per pound
Grocery store: $0.35 per ounce * 16 ounces = $5.60 per pound
Farmer's market: $0.30 per ounce * 16 ounces = $4.80 per pound
