Hannah finds purple, blue, and silver space rocks while exploring. 2/3 of the rocks are purple and 3/4 of the remainder are blue. if there are 3 silver rocks, how many space rocks does hannah have?

The number of space rocks that Hannah has = 36 space rocks

We are told that;

Fraction left that is not purple = ⅓

Thus;

Fraction that is silver = 1 - (fraction that is purple + fraction that is blue)

Fraction that is silver = 1 - (⅔ + ¼)

Fraction that is silver = 1/12

(1/12)x = 3

Where x is total number of space rocks.

Thus;

x = 12 × 3

x = 36

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.
