Answer:
76
Step-by-step explanation:
Survey response
Those who liked the proposed plan=380 persons
Those who didn't like the proposed plan=120 persons
We assume that the these are the only people who participated, with those who never took sides being zero
Total number of people surveyed=380 persons+120 persons=500 persons
Percentage of those who liked =
Therefore, the percentage that liked the plan is 76%
Each side is 36 inches. since it is a square all sides are the same length. 144 divided by 4 (number of sides) =36. hope that helps
P=2(L+W)
A=LW
given
P=62
62=2(L+W)
divide 2
31=L+W
minus W
L=31-W
sub into other one
A=LW
A=(31-W)(W)
228=31W-W^2
times -1
W^2-31W=-228
add 228 both sides
W^2-31W+228=0
factor
what 2 numbers multiply to get 228 and add to get -31
-19 and -12
(W-19)(W-12)=0
set to zero
W-19=0
W=19
W-12=0
W=12
sub back
L=31-W
L=31-12
L=19
or
L=31-19
L=12
the doorway is 12in by 19in
Answer:
Step-by-step explanation:
Pythagorean theorem:
x² + x² = (9√2)²
2x² = 162
x² = 81
x = 9
x = 1040/43 = $24.19 per day.
y = 10/43 = $0.23 per mile.
