Answer:

111

Step-by-step explanation:

divide 42 by 14 and get 3 then multiply 3 by 37 and get 111

Answer 2

Answer:

Final answer:

To find out the cost of 37 inches of wire at the same rate as 14 inches, we can set up a proportion. Solving for x in the proportion yields a cost of 111 cents for 37 inches of wire.

Explanation:

To find out how much 37 inches of wire will cost at the same rate, we can set up a proportion. We know that 14 inches of wire costs 42 cents, so we can say that the cost is directly proportional to the length. The proportion can be written as:

14 inches / 42 cents = 37 inches / x cents

To solve for x, we cross-multiply and get:

14x = 37 * 42

Dividing both sides by 14 gives us:

x = (37 * 42) / 14

Calculating this out, we find that:

x = 111 cents

Therefore, 37 inches of wire will cost 111 cents.

What is the volume of the right prism? A. 1680 in3 B. 3360 in3 C. 1288 in3 D. 1120 in3

Answers

To solve this question, first we multiply.

Before anything else, we must find the area of the triangle on either side of the prism. The measurements are 24 in. by 7 in., so we do that, which gives us 168 in.²

Then, we multiply this by the base length, which is 20 in.

168x20=3360, so the correct answer is B, 3,360 in³.

Hope I helped!

Answer:

The correct answer is A. 1680 in3.

Step-by-step explanation:

When I took the test I chose B. for my answer and it was wrong. The formula for the volume of a prism is V = Bh. The base on this prism is a triangle.
