1 answer:
alexira [117]3 years ago
7 0

Answer:

1. g. $0.10 per square inch

2. b. $0.08 per square inch

3. f. $10

4. m. $8

5. h. 79 in²

6. j. 113 in²

Step-by-step explanation:

1. A = πr²

  r = diameter ÷ 2 = 10 ÷ 2 = 5

  A = π(5)² = 25π in² ≈ 78.53981

  $8.00/25π = $0.10 per square inch

2. A = πr²

  r = diameter ÷ 2 = 12 ÷ 2 = 6

  A = π(6)² = 36π in² ≈ 113.0973355

  $10.00/36π = 0.088419 = $0.09 per square inch

3. information/answer was provided

4. information/answer was provided

5. A = πr²

  r = diameter ÷ 2 = 10 ÷ 2 = 5

  A = π(5)² = 25π in² ≈ 79 in²

6. A = πr²

  r = diameter ÷ 2 = 12 ÷ 2 = 6

  A = π(6)² = 36π in² ≈ 113 in²

Can you help me to create a histogram graph with the following data please?
AlekseyPX

The attached graph represents a histogram that has a range of 55

<h3>How to create the histogram?</h3>

The range is given as:

Range = 55

The range is calculated as:

Range = Maximum - Minimum

So, we have:

Maximum - Minimum = 55

Rewrite as:

Maximum = Minimum + 55

Let the minimum be 10.

So, we have:

Maximum = 10 + 55

Evaluate

Maximum = 65

The following dataset can be used to create the histogram

Score   Frequency

10           2

15            5

45          3

65         1

This is so because it has a range of 55

See attachment for the histogram

Can anyone help with this???
VikaD [51]

Answer:

56.25

Step-by-step explanation:

The number you need to add to both sides to complete the square needs to be calculated by doing (\frac{b}{2})². So, in this problem, b= -15.

-15/2 = -7.5, and -7.5² = 56.25. This is the number you will add to complete the square

Sidana [21]
Set up a proportion.

\sf\dfrac{20}{25}=\dfrac{50}{x}

Cross multiply:

\sf1250=20x

Divide 20 to both sides:

\sf~x=62.5

So it will take 62.5 minutes for her to complete the worksheet.
