Answer:
0.003
Step-by-step explanation:
Answer:
Let l be length and w be the width
l = 2w+12
Area = (2w+12)*w = 224
2w^2 + 12w - 224 = 0
w^2 + 6w - 112 = 0
using quadratic formula
w=[ -6 +- {36- 4*1*(-112)}^0.5]/2*1
w = [-6 +- {484}^0.5]/2
w = [-6 +- {22}]/2
w = 16/2 or -28/2
w = either 8 or -14
Width can not be a negative number
wI’d think= 8 ft
length = 2*8+12 = 28 ft
Step-by-step explanation:
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
The answer is 2
