What is the volume of the composite figure?
Romashka [77]

Answer:

1428 in³

Step-by-step explanation:

To find the volume of this figure, we will need to use two formulas. The volume of a Rectangular Prism (A= l * w * h) and volume of a triangular prism. A = \frac{1}{2}(b*h)

If we look at the Rectangular Prism, we can find that l = 17, w = 8, and h = 5. Multiply these to find the volume:

17 × 8 × 5 = 680 in³.

Solving for the triangular prism gives us:

A = 1/2 (11 ×  8 × 17)

A = 748.

Add these two volumes to find the volume of the composite figure:

748 + 680 = 1428 in³

Morgan has an investment worth $177,500. If his original investment was $50,000 and he received a 15% interest rate, how many ye
Illusion [34]
<h3>Morgan invested for 17 years</h3>

<em><u>Solution:</u></em>

From given,

Principal = $ 50, 000

Total amount = $ 177, 500

Rate of interest = 15 %

Number of years = ?

Interest amount = Total amount - principal

Interest amount = 177, 500 - 50, 000

Interest amount = 127500

<em><u>Use the formula,</u></em>

Interest = \frac{p \times n \times r}{100}\\\\127500 = \frac{ 50000 \times n \times 15}{100}\\\\127500 = 500 \times 15 \times n\\\\75n = 1275\\\\n = 17

Thus he invested for 17 years
