Answer:
a. V = 10*8*x
b. V= 10*8*22.5
Step-by-step explanation:
b. V= 1800
How many times your suppose to multiply it by.
D = 545.79
r = 48.3
Plug in numbers to corresponding variables
545.79 = t(48.3)
Isolate the t, divide 48.3 from both sides
(545.79)/48.3 = 48.3t/48.3
t = 545.79/48.3
t = 11.3
t = A) 11.3 h
hope this helps
we have
