Answer:

rectangular container

Step-by-step explanation:

Triangular prism area: A = 1/3 * base area * height

                                        = 1/3 * 12 * 19

                                        = 76 cm²

Rectangular prism: A = base area * height

                                   = 8 * 15

                                   = 120 cm²

The rectangular container has a better value because it has a bigger area and is cheaper.

Hope this helps!

Robert borrowed $750 from his parents. He promised to repay the loan by giving his parents at least $67 from his paycheck each w
Luda [366]

To answer this question we can propose the following equation:


d=750 -x(67)


Where:


x is the number of weeks elapsed.


d is the debt depending on the weeks.



Robert promised to pay at least $ 67 each week.


Therefore, after 5 weeks the debt of rober should be:


d\leq750-5*67

d\leq415


Then scenario A) is possible because 150.



After 6 weeks:


d\leq750-6*67


d\leq348

Then scenario B) is possible because 200.



After 7 weeks


d\leq750-7*67


d\leq281

Then scenario C) is possible because 250.



After 8 weeks

d\leq750-8*67

d\leq214

So scenario D) is NOT possible because 300>214



Finally the correct answer is option D.
