Let, the side of square = a
perimeter = 4a
two sides would be: a+a = 2a
it's ratio would be 4a/2a = 2
as, the number is not in fraction, so they are proportional
Answer:
0
Step-by-step explanation:
6x-12-6x+12=
0x-12+12=0
Pj = prop jet speed
pp = private plane speed
pj is 2.5 times faster than pp, therefore
A) pj = 2.5*pp
B) pj = 2*pp + 60
Substituting equation A into B
B) 2.5*pp = 2*pp +60
.5 * pp = 60
Private Plane travels at 120 mph
Prop jet = 2.5 * private plane = 300 mph
She could estimate that there would be about 148 million female drivers.
From her data, she found there were 118 females drivers out of the total 200 drivers that she counted.
That is 118 out of 200 or 0.59 or 59%.
Now, just take 59% of 250.
0.59 x 250 = 147.5 which rounds to 148.
