F(h)= 20 +25h
next plug in the hours but first you need to take the minutes and transfer them to hours
120 minutes = 2 hours
so you plug in 20 + 25(2)
that equals 70
therefor your answers are
f(h)= 20 +25h
and
$70
5.1 divided by 104 is 0.05 to the nearest tenth
Answer:
14.92 ounces per second
Step-by-step explanation:
SInce there is 128 oz in one gallon we have to break this down more. 195 seconds equals 3 minutes and 25 secs so 3 1/4 minutes. So we can do 128/60 because it's asking per minute. After that, you'll get 2.13, but since there's a total of 3 minutes you have to multiply that by 3. So 2.13 times 3 equals 6.39. Don't forget that we still have 15 seconds left, or 1/4 of a minute so you'll divide 128 by 15 and you'll get 8.53 in ounces. Add that to 6.39 and the final answer is 14.92 ounces per second
