You paint 1313 of a wall in 1414 hour. At that rate, how long will it take you to paint one wall?

Answers

You paint 1313 of a wall in 1414 hour.
Now we need to find the rate in order you to paint one wall.

1313 : 1414 = 1 : X
1414 = 1313 X
X = 1.08

So the rate per one wall is 1.08 hours.

Find the volume, to the nearest m3, of a cylinder with diameter 6 m and height 8 m.a.226 m3 c.207 m3 b.452 m3 d.151 m3

Answers

ANSWER

a. 226m³

EXPLANATION

The volume of a cylinder is calculated using the formula:

$Volume=\pi \: {r}^(2) h$

where r is the radius and h=8m is the height of the cylinder.

The radius is half of the diameter.

This means that:

$r = (d)/(2) = (6)/(2) = 3m$

We plug in the values into the formula to get:

$Volume=\pi * {3}^(2) * 8$

$Volume=72\pi$

$Volume=226.19 {m}^(3)$

To the nearest cubic meters, the volume is 226 m³.

The minimum monthly payment for Fern's credit card is 2.5% of her balance or $40, whichever is higher. If Fern's balance at the end of her last billing cycle was $1950, what is her minimum monthly payment?A.$48.75
B.$40.00
C.$8.75
D.$88.75

Answers

Answer:

A. $48.75.

Step-by-step explanation:

We have been given that the minimum monthly payment for Fern's credit card is 2.5% of her balance or $40, whichever is higher.

First of all let us find 2.5% of $1950.

$\text{2.5\% of \$1950}=(2.5)/(100)* \$1950$

$\text{2.5\% of \$1950}=0.025* \$1950$

$\text{2.5\% of \$1950}=\$48.75$

Since the minimum monthly payment will be the higher amount among 2.5% of the balance or $40. As $48.75 is higher than $40, therefore, Fern's minimum monthly payment will be $48.75 and option A is the correct choice.

1950 * .025
48.75
A

you began membership in a new health and fitness club which has access to a dietician and personal trainer. They help you develop a special eight-week diet and exercise program. The data in the following table represents your weight, w, as a function of time, t, over an eight-week period. Time (weeks) 0 1 2 3 4 5 6 7 8 Weight (lb) 150 144 143 141 140 137 137 132 129. If you lost 13 pounds in the first five weeks, what is the average rate of change of weight with respect to time over the first five weeks of the program?

Answers

Time (weeks) 0 1 2 3 4 5 6 7 8
Weight (lb) 150 144 143 141 140 137 137 132 129

Change in time (weeks) = 5 - 0 = 5 = -0.3846
Change in weight (lbs) 137 -150 -13

The average rate of change of weight with respect to time over the first five weeks of the program is -0.3846. It is a negative sign because the weight is decreasing.
