First, subtract 63 from 75 to find out how much it decreased.
75 - 63 = 12
Divide 12 by 75.
12 / 75 = 0.16
In percents, that is 16%.
He spent 16% less this month.
Hope this helps!
L ≥ 5w + 4
2(L+w) ≥ 32
L+w ≥ 16
6w + 4 ≥ 16
6w ≥ 12
w ≥ 2
L ≥ 5w + 4
L ≥ 14
If L = 14 and w = 2 then the perimeter is 32.
These are the smallest dimensions that fit the criteria.
Note: If we raise the width by 1 to w = 3
then the length is at least 19. At 19 by 3 we have P = 44
Like would be appreciated!!
Answer
a decrease of 0.2 gallons per second
Explanation
The drain was open for 30 seconds.
The water that ran out for 30 seconds = 20 - 14
= 6 gallons
Rate of decrease = (change in gallons)/(time taken)
= 6/30
= 0.2
The rate of change in the amount of water remaining in the tub per second will be the same as the one that ran out since the outlet is the same.
So the correct answer from the choices is "a decrease of 0.2 gallons per second".
Area Of Triangle:
4/2 = 2
2x6 = 12
12x2 = 24ft^2
Remaining area:
150 - 24 = 126ft^2
Maximum length:
126/6 = 21
x = 21ft
7 is the answer 4 and lower you round down 5 and up is up
