The fuel for a chain saw is a mix of oil and gasoline. The ratio of ounces of oil to gallons of gasoline is 4:12. There are 24 gallons of gasoline. How many ounces of oil are there?
2 ounces
8 ounces
72 ounces
14 ounces

8 ounces

Step-by-step explanation:

take 12 then multiply by 2, do the same with 4 so your ratio will equal your gallons. 4x2=8

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.
