Water comes out of a pipe at a rate of 12 gallons per minute. How many gallons have come out after 3 minutes?

After 3 minutes, 36 gallons of water comes out of the pipe.

Step-by-step explanation:

If 12 gallons come out per minute, you can simply multiply 12 gallons by 3 minutes, thus you end up with 36 gallons / 3 minutes.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
