Answer:

C

Step-by-step explanation:

Hose A:

60 gallons every 15 minutes mean:

60 / 15 = 4 gallons per minute

For Hose B:

If we put x = 1, we can find gallons (y)  per minute (x)

y = 3 x

y = 3(1)

y = 3

That means 3 gallons per minute

Thus, the rate of Hose A is 1 gallon per minute more than the rate of Hose B. Option C is correct.

Answer:

The correct answer is option C,

Step-by-step explanation:

Hose-A fills 60 gallons of water in 15 minutes .

Rate of Hose-A at which it fills water truck = R_a=\frac{60 gal}{15 min}=4 gal/min

Hose-B fills water truck , its function is given as:

y = 3x

Where y is the total number of gallons filled in x minutes.

Rate of Hose-B at which it fills water truck = R_b=\frac{y gal}{xmin}=\frac{3x}{x} gal/min=3 gal/min

Difference in rates of both hoses:

R_a-R_b=4 gal/min - 4gal/min = 1 gal/min

R_a-R_b=1 gal/min

R_a=R_b+1 gal/min

The rate of Hose A is 1 gallon per minute more than the rate of Hose B.

Going into the final exam, which will count as two tests, Brooke has test scores of 75, 82, 70, 65, and 90. What score does Broo
dusya [7]
Brooke needs to get a 98 on the final to get an average of 80.
So you know that the total of the five given score is 382 by adding all the scores.
Now you multiply the average, 80 by 6 for the total of six tests including the final which is 480
Then you subtract 480-382 to find your answer.
