Answer:
210 minutes
Step-by-step explanation:
First, we want to find out how many meters cubed of water there is, which is the volume.
The volume of this prism would be, the average of the two sides multiplied by 2 and 1.
1.5+0.6 = 2.1
2.1/2 = 1.05
1.05*2=2.1
2.1*1=2.1
2.1 meters is the volume but because it goes down by 30 cm, we have to convert 2.1 to cm.
2.1 * 100 = 210 cm.
Every 30 minutes, it goes down by 30 cm so:
210/30 = 7
210 minutes until it's empty

Step-by-step explanation:
-24
Step-by-step explanation:
-2/3d -1/4d=22
First give the fractions a common denominator.
-8/12d-3/12d=22
Then combine like terms.
-11/12d=22
Then divide 22 by the coefficient - 11/12d.
This comes out to equal -24.
Divide 180 by 5 to get A-36
