Answer:
15 gallons
Step-by-step explanation:
Given that:
Pumping rate is modeled by the equation :
Q(t)=45-t gallons per minute ; where t is in minutes
Number of gallons in tank after 30 minutes ;
Q(t)=45-t
Q(30) = 45 - 30
Q(30) = 15
Hence, Number of gallons in tank after 30 minutes is 15 gallons
I think it's B. 5/9(F -32) < 140
B
16 + 16 + 16 = 16 x 3
16 x 3 = 48
16 + 16 = 32
32 + 16 = 48
