Which is the solution set of the compound inequality 3.5 x minus 10 greater-than negative 3 and 8 x minus 9 less-than 39
dexar [7]

The solution for the compound inequality is x \in(2,6)

Explanation:

The equations are 3.5x-10>-3 and 8x-9

To find the solution set for these compound inequalities, we need to solve the inequality.

First, we shall solve the inequality 3.5x-10>-3

Adding both sides of the equation by 10, we have,

3.5x>7

Dividing both sides by 3.5, we get,

x>2

Now, we shall solve the inequality 8x-9,

Adding both sides of the equation by 9, we have,

8x

Dividing both sides by 8, we get,

x

Thus, the solution set for the inequalities 3.5x-10>-3 and 8x-9 is x \in(2,6)

A pool measures 12.3 feet by 16.6 feet. If the longer wall of the pool has a diagonal of 17.8 feet, what is the volume of the po
Harman [31]

Answer:

1310.8 feet^3 to nearest tenth.

Step-by-step explanation:

To find the volume we need to find the depth.

The length of the diagonal helps us to do this. We apply the Pythagoras theorem to the triangle formed by the length, the diagonal and the depth (d):

17.8^2 = d^2 + 16.6^2

d^2 = 17.8^2 - 16.6^2

d^2 = 41.28

So the depth d =  6.42 feet.

Thus, the volume = 16.6 * 12.3 * 6.42

=  1310.8 feet^3.
