1. A cone-shaped container is filled with water. The container has a height of 18 inches and a diameter of 9 inches. How much water is in the container ? 2. There are 12 cylindrical cans in a package. each has a height of 4.9 in. and a diameter of 2.5 in. what’s the total volume of the 12 cans ?

3. Tom is filling a spherical beach ball with air for the pool party. The ball has a radius of 8 inches . what is the approximate amount of air the ball will hold?

PLEASE ILL MARK BRAIN-LIST IF CORRECT ! :)

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.

Factor the following expression. 27y3 – 343 a. (3y + 7)(9y2 + 2ly + 49) b. (3y – 7)(9y2 + 2ly + 49) c. (3y – 7)(932 – 217 + 49) d. (3y + 7)(92 – 2ly + 49)

The diagram represents the polynomial 4x2 + 23x – 72. what is the factored form of 4x2 + 23x – 72? (4x + 8)(x – 9) (4x – 8)(x + 9) (4x + 9)(x – 8) (4x – 9)(x + 8)
