Answer:
FALSE
Step-by-step explanation:
Area of triangle is given by formula :
From picture we see that Altitude = 60 m
Base = 52 + 71 = 123 m
Now plug these values into above formula:
Which is different than given area 1560 m^2.
Hence answer is FALSE.
13.9
it’s a special triangle and that side would be 8√3 which is 13.9
Answer:
8 hours
Step-by-step explanation:
basic equation
Q (flow rate) = V (volume)/ t (time)
so to find the time we just rearrange the equation and become
t = V/Q
V of cylinder
V = πr²T
and r (radius) = ½ diameter
V = 3.14 x 5² x 1.4
V = 109.9 m³
if the Q is 13 m³/hour then
t = 109.9/13 = 8.453 hours
round to nearest hour = 8 hours
A for the first one and D for the second
Probably a C-, but it depends on how many other grades are in the gradebook and the exact percentage of your grade.
