So it will take 62.5 minutes for her to complete the worksheet.
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
7/9 divided by 5/6
whenever dividing , always flip over the second fraction
7/9*6/5
cross out 9 and 6 , divide by 3
9/3=3
6/3= 2
7/3*2/5
mutiply the numerators together : 7*2= 14
mutiply the denominators together: 3*5= 15
answer:
14/15
Answer:
19
Step-by-step explanation:
the value of f(x) = 2x^2 + 1, for x = 3
f(3) = 2×3^2 + 1➡ 2×9 +1= 19
