Answer:
4 hours
Step-by-step explanation:
Each hour: 145.60/7 = 20.80
83.20/20.80 = 4
We are going to consider a rectangle with length called "a" and width "b" Then we know that perimeter is the sum of both sides 2*a + 2*b = 128 And also the following equation given by the question: a = 2*b + 3 So solving the first equation: 2*(2*b+3) + 2*b = 128 4*b+6+2*b=128 6*b = 122 b = 122/6 = 61/3 Then a=2*122/6+3 = 244/6+3 = 262/6 = 131/3 Solution: Length = 131/3 Width = 61/3
Answer:
2
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
First we need to convert 600 miles per hour into feet per hour,
which is
# 3.168e+6
next, divide both by 60 to get feet per minute, then divide by 60 again on both sides to get feet per second
which is
#880 ft per second
Answer:
$5.00
Step-by-step explanation:
All we have to do is multiply 25 x 1/5 or 20%
25 x 1/5 = $5.00
to check, $5 x 5 = 25
