The answer should be 390=60s, assuming s is the number of shelves he would need.

By the way, if you want the answer using this formula:
390=60s
390/60=s
6.5=s
s=6.5

Answer:

68.8 sq. inches.

Step-by-step explanation:

The triangular surfaces have sides 2 in by 3 in by 4 in.

So, half perimeter, s = \frac{2 + 3 + 4}{2} = 4.5

So, the area of the triangular face is \sqrt{s(s - 4)(s - 2)(s - 3)} = \sqrt{4.5 \times 0.5 \times 2.5 \times 1.5} = 2.9 sq. inches.

Now, the total surface area of the right triangular prism will be (2.9 × 2) + 7(2 + 3 + 4) = 68.8 sq. inches. (Answer)

Which correctly describes how the graph of the inequality −4y − x ≥ 7 is shaded?
harkovskaia [24]

Answer: Below the solid line

Step-by-step explanation:

-4y - x ≥ 7

add x to both sides

-4y ≥ x + 7

divide by -4 on both sides

y ≤ -1/4x - 7/4 = (1.75)

Take the origin (0,0) and substitute it for the variables

y(0) ≤ -1/4(0) - 7/4

0 ≤ -7/4 = (1.75)

This statement is false, so you would shade on a graph, below the solid line, since this is where the origin would not be.

The line would be solid because the < is underlined.
