150 people
Step-by-step explanation:
20/50 = 40%
So 40% are wearing hats and 60% aren't
0.6=60%
250x0.6= 150
Answer:
dh/dt ≈ 0.55 ft/min
Step-by-step explanation:
The volume is given by the formula ...
V = (1/3)πr²h
We have r = h/2, so the volume as a function of height is ...
V = (1/3)π(h/2)²h = (π/12)h³
Then the rates of change are related by ...
dV/dt = (π/4)h²·dh/dt
dh/dt = (4·dV/dt)/(πh²) = 4(35 ft³/min)/(π(9 ft)²)
dh/dt ≈ 0.55 ft/min
Answer:
3
Step-by-step explanation:
1/3 of 9 is 3
you would figure this out by dividing the total amount of books by the denominator of the fraction.
9/3=3
Answer:
The actual distance is 11.7km
Step-by-step explanation:
2cm = 1km
1cm = 0.5km
23.4cm = ?
23.4 × 0.5 = 11.7km
(Correct me if i am wrong)
A. x-12=15 x = 27
b. x+x+1+x+2 = 234 3x = 231 x=77 so the numbers are 77,78,79
