We have to find the percentage ratio of two numbers. It is
. And the correct answer is D).
Alternatively, by setting up a ratio, we can write that If
400_____100%
36_____x
And x=9%
P = 2(L + W)
L = W + 5
A = 4P + 2
P = 2(W + 5 + W)
P = 2(2W + 5)
P = 4W + 10
A = 4P + 2
A = 4(4W + 10) + 2
A = 16W + 42
A = L * W
A = W(W + 5)
A = W^2 + 5W
W^2 + 5W = 16W + 42
W^2 + 5W - 16W - 42 = 0
W^2 - 11W - 42 = 0
(W + 3)(W - 14) = 0
W - 14 = 0
W = 14 <==
L = W + 5
L = 14 + 5
L = 19 <==
P = 2(19 + 14)
P = 2(33)
P = 66
A = L * W
A = 19 * 14
A = 266
answer : length = 19, width = 14....perimeter = 66....area = 266
Answer- 1.159, 1.157, 1.156.
Answer:
3 complete shifts of 3/4 hour and 1 one-third of the 3/4 hour shift.
Step-by-step explanation:
Total work hours = 2.5 hours
Each shift = 0.75 hr
Number of shifts = Total work hours / Each shift
= 2.5 / 0.75
= 3.33
He worked for 3 complete shifts of 3/4 hour and
1 one-third of the 3/4 hour shift.
