a fish dives into a depth of -3/4 miles below the surface of the water. A turtle's depth is 1/3 as deep as the fish's depth. Wha

Tcecarenko [31]

One mile = 5280 feet

-3/4 * 5280 = 1320(-3)

The depth of the fish is -3960 feet under the water.

A turtle is 1/3 * (-3960).

So, 1/3 * (-3960) = -1320(1).

The turtle's depth is -1320 feet under the water.

What is the solution to 2x-8 < 12?

Sonbull [250]

Answer:

x < 10

Step-by-step explanation:

2x-8 < 12

2x < 12+8

2x < 20

x < 20/2

x < 10

that means the highest value of x will be 9

Luba_88 [7]

Answer:

The surface area of the triangular prism is approximately 401.582 square feet.

Step-by-step explanation:

The figure represents a triangular prism, the procedure for calculating the surface area of the entire figure consists in adding the areas of each face (3 rectangles and 2 triangles):

$A = 2\cdot \left[\frac{1}{2}\cdot (9\,ft)\cdot (4\,ft)\right] + (16\,ft)\cdot (4\,ft) + (9\,ft)\cdot (16\,ft) + (16\,ft)\cdot \sqrt{(9\,ft)^{2}+(4\,ft)^{2}}$ $A \approx 401.582\,ft^{2}$

The surface area of the triangular prism is approximately 401.582 square feet.
