The 4 people in your crew each spent 4 hours laying sod. how many person-hours is this?

Since there are 4 people and they each spent 4 hours working, all we have to do is multiply the number of people (4) by the amount of hours each person spent (4)

4 x 4 = 16

Therefore, the total amount of hours is 16

Hope this helps you

ryan had a head start of 10 meters.

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.
