The ratio of boys to girls in a science class is 8:7. If there are 14 girls, how many boys are in the class?

16

Step-by-step explanation: If the ratio is 8 boys for every 7 girls and there are 14 girls, that means there are 2x the amount of girls in the ratio. 7 -> 14. This means that there are also 2x as many boys. 8 -> 16.

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.
