Answer:
0.58cm
Step-by-step explanation:
l×b×h=volume
Given:
Voume=28cm^3
l=8cm
width or breadth=6cm
h=?
applying the above formula
l×b×h=28cm^3
6×8×h=28cm^3
h=28/48=0.58cm
Answer:
You are right
Step-by-step explanation:
Since if he gets the driveway done in 20 minutes he gets 1/20th of the driveway done in 1 minute (if x=20 then x/20=1 by dividing both sides by 20) and if his brother gets 1/12th of the driveway done in one minute, then if t represents the time it takes to shovel the driveway, t/20+t/12=1 driveway shoveled as 1/20+1/12=amount they can do in 1 minute, so t/20+t/12 is how much they can do in t minutes. Multiplying both sides by 20*12=240, we get 12t+20t=32t=240. Dividing both sides by 32, we get 240/32=7.5 minutes to shovel the driveway.
