A terrarium is built in the shape of a triangular prism. The prism is 10 inches in height and contains 450 cubic inches of space
Stells [14]

Answer:

45 square inches

Step-by-step explanation:

We are told that a terrarium is constructed in a triangular prism shape with the following 10 inches tall and 450 cubic inches in volume.

We are asked to calculate the area of the base shape of the prism, we know that the volume of any triangular prism is equal to the area of the base times the height therefore:

450 = W × 10

we solve for A:

A = 450/10

A = 45

Which means that the base area is 45 square inches

Regina, Phil and Joseph each wrote expressions to represent their hourly earnings for an after-school job where h represents the
Citrus2011 [14]

Answer:

h=-15, -15 hours is your answer. You can't work negative hours though which means that Regina and Phil will never be able to make the same amount.

Phil has a higher rate and starting value, this means that Regina will never make the same amount working the same hours.

Step-by-step explanation:

Regina: 6.5h

Phil: 3(2.5h+5)

When you plug in the number of hours, you get the weekly pay.  In order to get the same weekly pay, set the equations equal to each other.

6.5h=3(2.5h+5), This is an equation to find the number of hours it will take for them to get equal pay. Now, simplify.

6.5h=7.5h+15

-h=15

h=-15, -15 hours is your answer. You can't work negative hours though which means that Regina and Phil will never be able to make the same amount.

Phil has a higher rate and starting value, this means that Regina will never make the same amount working the same hours.
