Carol's first grading period has ended. There were six test scores for the grading period; however, she did not record two of her scores. She knows the two unrecorded test scores are the same. The scores she did record were 92, 84, 86, and 94. What score did she earn on each of the two tests if her average score for the period is 90? A. 91
B.90.5
C. 92
D. 91.5

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

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.
