Pittsburgh, Pennsylvania and State College, Pennsylvania are 9.8 inches apart on a map that has a scale showing 1.1 inches equal to 15 miles. How far apart are the cities in real life?

the answer is 15% decrease

tube or goog would be a great resource to with that question

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.
