Jennifer needs to make an average of at least $350 per week. If she makes $385, $326, and $298 for the first 3 weeks of the mont

ella [17]

385 + 326 + 298 = 1,009 / 3 = 336.33

385 + 326 + 298 + x = 350

350 x 4 = 1,400
1,400 - 1,009 = 391

385 + 326 + 298 + 391 = 1,400 / 4 = 350

The answer is $391

A solid right pyramid has a regular hexagonal base with an area of 7.4 units2. The pyramid has a height of 6 units.

Lelechka [254]

Answer: Second option.

Step-by-step explanation:

You need to use the following formula:

$V=\frac{1}{3}Bh$

Where "B" is the area of its base and "h" is the height.

According to the data given in the exercise, you know that:

$B=7.4 units^2\\\\h=6\ units$

Therefore, knowing this values, you can substitute them into the formula shown before and then evaluate, in order to calculate the volume of thi right pyramid whose base is a regular hexagon.

Then, you get:

$V=\frac{1}{3}(7.4 units^2)(6\ units)\\\\V=14.8\ units^3$
