Answer:

Step-by-step explanation:

z+x*y

Start by plugging the corresponding values in.

2 4/5 + 3/5*1/3

Multiply first. (Order of operations)

Note: When multiplying fractions, simply multiply the denominators together, and then the numerators together.

2 4/5 + 3/15

Simplify.

(I divided 3/15 by 3/3, which just equals 1.)

2 4/5 + 1/5

Add.

2 5/5

Simplify

Answer:

The third graph down

Step-by-step explanation:

-2.1 w > 12.81

Divide each side by -2.1, remembering to flip the inequality

-2.1w / -2.1 < 12.81/ -2.1

Answer:

A. $V = (pi)(3.25)^2(12)$

Step-by-step explanation:

The formula for the volume of a cylinder is the formula for the area of the circle, times the height of the cylinder. The formula for the volume of a circle is,

$A = (pi)(r)^2$

Multiply that by the height to find the formula for the volume of a cylinder,

$V=(pi)(r)^2(h)$

Where (pi) represents the value (3.1415), (r) represents the radius, and (h) represents the height of the cylinder. Now substitute in the given values, remember, this problem gives the diameter of the cylinder, divide that value by two to find the radius.

$V=(pi)(\frac{6.5}{2})^2(12)\\\\V = (pi)(3.25)^2(12)$
