Answer:

6 7/12

Step-by-step explanation:

-7 2/3 +(5 1/2) + 8 3/4

Get a common denominator of 12

-7 2/3 * 4/4 +(5 1/2 +6/6) + 8 3/4*3/3

-7 8/12 + 5 6/12 + 8 9/12

Subtract the first two terms first

They have opposite signs so subtract and take the sign of the larger

-7 8/12 + 5 6/12 = -2 2/12

-2 2/12 + 8 9/12

They have opposite signs so subtract and take the sign of the larger

-2 2/12 + 8 9/12 = 6 7/12

Answer:

-12

-10

-5

-14

Step-by-step explanation:

First, you want to do inverse operations

M/-5 < 3

Just multiply -5 with 3

You have to flip the inequality sign because you multiplied by a negative

Answer: M > -15

Now what is greater than -15?

Answer =

-12

-10

-5

Answer:

(D) 30pi inches

Step-by-step explanation:

First, we use the given volume, the given height, and the formula of the volume of a cylinder to find the radius of the base. Then we use the radius of the base to find the circumference of the base.

$volume = \pi r^2 h$

$volume = 6750 \pi~in.^3$

We set the formula equal to the volume and replace h with 30 in.

$\pi r^2 h = 6750 \pi~in.^3$

$\pi r^2 \times 30 ~in. = 6750 \pi~in.^3$

Divide both sides by 30pi in.

$r^2 = 225 ~in.^2$

Take the square root of each side.

$\sqrt{r^2} = \sqrt{225 ~in.^2}$

$r = 15~in.$

The radius of the base is 15 in.

Now we use the radius of the base and the formula of the circumference of a circle to find the answer.

$circumference = 2 \pi r$

$circumference = 2 \pi \times 15~in.$

$circumference = 30 \pi ~in.$

Answer:

J(t) = 230,600(1.009)^t

Step-by-step explanation:

J(t) = 230,600(1 + 0.009)^t, or

J(t) = 230,600(1.009)^t
