12 minutes because it is three miles into for the train to go completely in and out (one mile for the nose to enter, on mile for the nose to exit and tail enter, and one mile for tail to exit). 3/15=x/60
1/8 of 144= 18 (red apples). 1/4 of 144= 36 (green apples). Oranges = 36+18= 54, equal to 144-54= 90. Therefore, there are 90 oranges, and this is equal to 90/144, or 45/ 72 or 15/24 or 5/8. Hope this helps :)
Answer:
5
Step-by-step explanation:
● 2(5v+3) - 4(7v+1) = -88
● 10v + 6 - 28v - 4 = -88
● (6-4) + (10v-28v) = -88
● 2 + -18 v = -88
● -18v = -90
● v = 90/18
● v = 5
Answer:
To calculate what you need, multiply the walkway's width and length to find the square footage.
Step-by-step explanation:
To calculate what you need, multiply the walkway's width and length to find the square footage; for example a 4-foot-wide, 50-foot-long walkway covers 200 square feet. Next, factor in the thickness: 4 inches converts to 0.33 feet; multiply this by the square footage to find the cubic feet: 200 x 0.33 = 66 cubic feet.
