Myra is cooking meat the double number line shows that he needs 12 hours too cook 5 kilograms of meat how long does myron need to cook 3 kilograms of meat

7.2 hours

Step-by-step explanation:

Myra is cooking meat the double number line shows that he needs 12 hours too cook 5 kilograms of meat

12 hours to cook 5 kilograms of meet

we need to find the number of hours needs to cook 3 kilograms

Let x be the number of hours to cook 3 kilograms

Make a proportion

solve for x

cross multiply it

Divide both sides by 5

so x= 7.2 hours

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.
