Hello,
Let's
V1 the velocity of the 1st bricklayer,
V2 the velocity of the 2nd bricklayer,
1wall=V1*6==>V1=w/6
1wall=V2*4==>V2=w/4
==>V1+V2=w/6+w/4=10w*24=5w/12
Let's t the time for the 2 bricklayer to build the wall
(V1+V2)t=w
==>5w/12*t=w
==>t=12/5 (h)=2h24min.
Answer:
Add each side to get perimeter so your total is 38ft
Step-by-step explanation:
Answer:
$45
Step-by-step explanation:
60/4=15 15x3(75%)=45
First, you need to create a unit rate.
The car travels 182 miles on 14 gallons of gas.
To create a unit rate, you would have to divide 14 by 182.
182 mi 13 mi
———— = ———-
14 gal 1 gal
Then, you would need to multiply the numerator and denominator by 8 because the question is asking how far the car can travel on 8 gallons of gas.
13 mi x 8 104 mi
——— = ————
1 gal x 8 8 gal
So, your answer is the car travels 104 miles on 8 gallons of gas.
