The ratio of red jellybeans to yellow jellybeans to blue jellybeans in a bowl is
3: 2: 5. if there are a total of 80 jellybeans, then how many of each color is in the bowl?

see explanation

Step-by-step explanation:

Sum the parts of the ratio, that is 3 + 2 + 5 = 10

Divide the total jellybeans by 10 to find the value of one part of the ratio

80 ÷ 10 = 8 ← value of 1 part of the ratio, thus

red jellybeans = 3 × 8 = 24

yellow jellybeans = 2 × 8 = 16

blue jellybeans = 5 × 8 = 40

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

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.
