Jada walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water. At what rate is the amount of water in the tank changing?

The rate at which the tank is changing water is 2/3 gallons per minute

Step-by-step explanation:

Step 1

In 3 mins, the tank losses 7 gallons of water - 5 gallons of water

= 7- 5 = 2 gallons of water

In  3 minutes, the tank loses , 2 gallons of water

step 2

To find  rate at which amount of water is changing

if 3 minutes, tank loses 2 gallons of water.

then 1 minute the tank will lose = 2/3 gallons

Therefore rate at which tank is changing water is 2/3 gallons per minute

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

answer: 72: 111
