At t=0 the altidude is 4500 feet
It's descending at a rate of 150 feet per minute, then each 5 minutes it descends (150 feet/min)(5 min)=750 feet. Then:
At t=5 the altitude is 4500 feet-750 feet=3750 feet
At t=10 the altitude is 3750 feet-750 feet=3000 feet

727
At t=0 the altidude is 600 feet
It's climbing at a rate of 75 feet per minute, then each 5 minutes it climbs (75 feet/min)(5 min)=375 feet. Then:
At t=5 the altitude is 600 feet+375 feet=975 feet
At t=10 the altitude is 975 feet+375 feet=1350 feet

The graph with these characteristics is Graph B.

Answer: The graph B shows when the two planes will be at the same altitude

A soccer team uses 5-gallon coolers to hold water during games and practices. Each cooler holds 640 fluid ounces. The team has s
polet [3.4K]
<h3>Answer:   640c - 6.25s - 8.75g</h3>

===============================================

Work Shown:

s = number of small cups

g = number of large cups

c = number of coolers

----------

1 cooler = 640 fluid ounces

c coolers = 640c fluid ounces

1 small cup = 6.25 fluid ounces

s small cups = 6.25s fluid ounces

1 large cup = 8.75 fluid ounces

g large cups = 8.75g fluid ounces

----------

T = total amount of water poured

T = (amount from small cups) + (amount from large cups)

T = 6.25s+8.75g

L = amount of water left

L = (original total amount of water) - (amount of water poured out)

L = 640c - T

L = 640c - (6.25s+8.75g)

L = 640c - 6.25s - 8.75g
