What is the volume of a sphere with a radius, r = 0.5?
Use 3.14 for and be sure you round your answer to two decimals.

Answers

Answer 1

Answer:

0.52 cubic units

Step-by-step explanation:

\(V_{sphere} = \frac{4}{3} \pi {r}^{3} \\ \\ = \frac{4}{3} \times 3.14 \times {(0.5)}^{3} \\ \\ = \frac{4}{3} \times 3.14 \times 0.125 \\ \\ = \frac{1.57}{3} \\ \\ = 0.523333333 \\ \\ = 0.52 \: {units}^{3} \\ \)

Using a proportion, how can we find 12% of 125? Please show your proportion set up and all work. HELP ME ASAPPPPPPPPP THE CORRECT ANWSER GETS A BRAINLIST I HAVE 3MINS SOMEONE PLEASE!!!!!

Answers

Answer: 15

Step-by-step explanation:

Write 12% as a fraction: 12/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have: 12/100 of 125.

12/100 × 125

If you are using a calculator, enter 12÷100×125 which will give you 15 as the answer.

Answers

Answer:   31

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

The volume of a sphere is 1,766,250 cubic meters. What is the radius of the sphere? Use 3.14 to approximate pi.

Answers

Answer:

75m^3

Step-by-step explanation:

\(\hookrightarrow \: volume = 1766250 {m}^{2} \)

As we have,

\(\hookrightarrow \: volume = \frac{4}{3} \pi {r}^{3} \)

Now,

\(\hookrightarrow \: 1766250 {m}^{3} = \frac{4}{3} \times 3.14 \times {r}^{ 3} \\ \hookrightarrow \: 5298750 {m}^{3} = 12.56 {r}^{3} \\ \hookrightarrow \frac{5298750 {m}^{3} }{12.56} = {r}^{3} \\ \hookrightarrow {r}^{3} = 421875 {m}^{3} \\ \hookrightarrow r = \sqrt[3]{421875 {m}^{3} } \\ \hookrightarrow 75 {m}^{3} \)

If a value of 80.8° is added to the data, how does the range change?

Answers

Answer:

The original data set would be:

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

So to find the range you would do:

105 - 57 which equals 48.

So the range for the original data set would be 48.

The new data set adding 80.8:

57, 58, 61, 66, 71, 77, 80.8, 82, 91, 95, 100, 102, 105

So to find the range for the new data set you would do:

105 - 57 which would still equal 48.

So the range for the new data set would be 48.

The range for the original and new data set stayed the same.

Step-by-step explanation:

You're welcome.

Step 1: find the original data set is 57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105.

Step 2: find the range

105 - 57 = 48

The range for the original data set is 48.



The new data set is adding 80.8

Step 1: find the new data set.

57, 58, 61, 66, 71, 77, 80.8, 82, 91, 95, 100, 102, 105

Step 2: find the range

105 - 57 = 48.

The range is still the same for the original and new data set.

Answers

An isosceles triangle has 2 sides that are equal.

I plotted these points. See attached screenshot.

The first side's distance is 5. You can just count those units along the x axis. (0,0) and (5,0) share the same y coordinate, so the difference in x coordinates is 5-0 = 5.

The next sides's distance is also 5. You can count that distance on the coordinate plane. (5,5) and (5,0) share the same x coordinate, so the difference in y coordinates is 5-0 = 5.

These two sides make a right triangle and are equal length. This is an isosceles right triangle.

Dominic is a server at a restaurant. Each dish at the restaurant costs $8. A sales tax of 8% is charged. The total bill amount includes the sales tax of the meal.

Dominic earns tips left by customers. The amount of money tipped can be represented by a percentage of the total bill.

Order the tip amounts from least to greatest tip, in dollars.

5 dishes
17.5% tip

6 dishes
14% tip

7 dishes
11% tip

4 dishes
20% tip

Answers

Answer:

In this order is least to greatest:

1. 4 dishes-20% tip

2. 6 dishes -14% tip

3. 7 dishes-11% tip

4. 5 dishes-17.5% tip

Order the tip amounts from least to greatest tip will be $6.65, $6.91, $7.25, and $7.56.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Dominic is a server at a restaurant. Each dish at the restaurant costs $8. A sales tax of 8% is charged. The total bill amount includes the sales tax of the meal.

The amount of tip for all the orders, then we have

A. 5 dishes and 17.5% tip, then the tip cost is given as,

⇒ ($8 x 5) x (1.08) x (0.175)

⇒ $7.56

B. 6 dishes and 14% tip, then the tip cost is given as,

⇒ ($8 x 6) x (1.08) x (0.14)

⇒ $7.26

C. 7 dishes and 11% tip, then the tip cost is given as,

⇒ ($8 x 7) x (1.08) x (0.11)

⇒ $6.65

D. 4 dishes and 20% tip, then the tip cost is given as,

⇒ ($8 x 4) x (1.08) x (0.20)

⇒ $6.91

Order the tip amounts from least to greatest tip will be $6.65, $6.91, $7.25, and $7.56.

janine wants to build a model using 1/2 inch cube how many 1/2 inch cube would she use to build a solid, cube-shaped model with side lengths of 4 inches? show your work

Answers

Answer:

512 1/2 inch cubes

Step-by-step explanation:

-In order to get 4 inches width, you will need 8 1/2 cubes (1/2 x 8 = 4)

-In order to get 4 inches height, you will need 8 1/2 cubes (1/2 x 8 = 4)

-In order to get 4 inches length, you will need 8 1/2 cubes (1/2 x 8 = 4)

8 length x 8 width x 8 height = 512 1/2 inch cubes to build a solid 4x4x4 inch cube.
