The cost per hour for making and decorating is given by th matrix below. which product does it cost $6.50 to bake and decorate 1 unit (picture provided)

b. Sheet Cake

Step-by-step explanation:

We have to first find the cost of all 3 products to find out which one will cost $6.50 to bake and decorate.

In order to find the cost, we need to multiply the time required by each product with its hourly cost.

For Giant Cookie:

Total Cost = Cost of 0.5 hours Baking + 0.25 hours Decorating

= 0.5(4) + 0.25(7)

=  $ 3.75

For Sheet Cake:

Total Cost = Cost of 0.75 hours Baking + 0.5 hours Decorating

= 0.75(4) + 0.5(7)

=  $ 6.5

For 3-Tired Cake:

Total Cost = Cost of 1.5 hours Baking + 1.25 hours Decorating

= 1.5 (4) + 1.25(7)

=  $ 10.75

Thus, Sheet Cake costs $ 6.50 to bake and decorate.

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.
