Carlos worked 31.5 hours at a hospital as a volunteer. This represents 87.5% of his school’s requirement for community service. How many hours does the school require for community service?

Answers

Answer 1

Answer:

The answer to this question would be (to my best guess), 36 hours.

Step-by-step explanation:

First

 You have to find the ratio between 87.5% and 100%. This is because you want to find what 100% represents.

To do this, you have to divide 100 by 87.5, which would represent 100 divided by 87.5. This will equal 1.142857142857143 , which isnt an easy number to work with.

Lastly

 You have to multiply 1.142857142857143 by 31.5, because you reverse the previous operation, but the only difference is you swap out the percentages with the numbers they represent. This equals the final answer, which is 36, representing 36 hours.

Answer:

48% is A and since i like quarters more than nickels and dimes its c for 30

Step-by-step explanation: Because I said so.

Answer:

To calculate the average you must add the percentages up and divide by the number of percentages. So, 52+28+34+95+16+63=288/6=48. The percentage is 48%.

For the second questions you take 100 divide by 3 since there are 3 coins and you get an 33.3%. But, since you can't have 0.3 of a coin. So, since you started with a nickel, you would end with a nickel giving you a percentage of 34% and the dimes and quarters a percentage of 33% each.

What is the mDEF? plz help

Answers

Answer:

m∠DEF = 148°

Step-by-step explanation:

The total sum of angles inside a triangle is 180°

m∠FDE + m∠EFD + m∠DEF = 180°

We can also see that because two sides are congruent, their angles are also congruent, so we can solve for x

m∠FDE = m∠EFD

2x + 8 = 3x + 4; subtract 2x from both sides

8 = x + 4; subtract 4 from both sides

x = 4; now we can substitute into equations

m∠FDE = m∠EFD;

2(4) + 8 = 3(4) + 4

8 + 8 = 12 + 4; 16=16; therefore = m∠FDE = m∠EFD = 16

To solve for m∠DEF

m∠FDE + m∠EFD + m∠DEF = 180°

16 + 16 + m∠DEF = 180

m∠DEF = 148°

An airline has two flights each day from City A to City B. A random sample of 10 morning flights left the gate an average of 15 minutes late with a standard deviation of 5 minutes. A random sample of 10 evening flights left the gate an average of 20 minutes late with a standard deviation of 3 minutes. Suppose both the morning and evening flights are 30 minutes late. To determine which flight is more late than usual, first find the z-scores. Round to one decimal place if necessary.

Answers

Answer:

Step-by-step explanation:

Let X denote the random variable that obeys the normal distribution.

Given that:

For morning flights

Mean [tex]\mu_1[/tex] = 15

standard deviation [tex]\sigma_1[/tex] = 5

Sample size [tex]n_1[/tex] = 10

[tex]X_1 \sim Normal ( \mu_1, \sigma _1)[/tex]

The Z - score is calculated as:

[tex]Z = \dfrac{x_1 - \mu_1}{\sigma_1}[/tex]

[tex]Z = \dfrac{30 -15}{5}[/tex]

[tex]Z = \dfrac{15}{5}[/tex]

Z = 3

For evening flights

Mean [tex]\mu_2[/tex] = 20

standard deviation [tex]\sigma_2[/tex] = 3

Sample size [tex]n_2[/tex] = 10

[tex]X_2 \sim Normal ( \mu_2, \sigma _2)[/tex]

[tex]Z = \dfrac{x_2 - \mu_2}{\sigma_2}[/tex]

[tex]Z = \dfrac{30 -20}{3}[/tex]

[tex]Z = \dfrac{10}{3}[/tex]

Z = 3.33

Hence, from the above z-scores, we will realize that the evening flight is more late than usual.

A sculpting tool is in the shape of a solid triangular prism. The tool is made of 12 in.3 of metal and is 4 in. Long. What is the height of the base if it is 2 in. Wide?

Answers

Answer:

The height of the base if it is 2 in. Wide is 3 inches

Step-by-step explanation:

Volume of rectangular prism = [tex]\frac{1}{2} \times Length \times Base \times Height[/tex]

Volume of given rectangular prism = [tex]12 in^3[/tex]

Length of prism = 4 in

Base of prism = 2 in

Substitute the values in formula

So, [tex]12 = \frac{1}{2} \times 4 \times 2 \times Height[/tex]

[tex]\frac{12 \times 2}{4 \times 2}=Height[/tex]

3 = Height

Hence the height of the base if it is 2 in. Wide is 3 inches

3 inches
