Answer:
19.6 gallons
Step-by-step explanation:
225/10=441/G
cross multiply
225G=10*441
225G=4410
G=4410/225
G=19.6 gallons of gas
Answer:
All have a rate of change of 4.
Step-by-step explanation:
To simplify some things, we're going to be dividing by 10 because that's the separation between each answer. (40-50, 50-60, 60-70, yadda yadda yadda)
From 40 to 50 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 0 and 40 is 40.
From 50 to 60 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 40 and 80 is 40.
From 60 to 70 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 80 and 120 is 40.
From 70 to 80 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 120 and 160 is 40
From 80 to 90 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 0 and 160 is 200
