Mathematics

Answer: 14.32 degrees

The circle has a diameter of 8 kilometers, so the perimeter would be:
perimeter= pi * diameter
perimeter= 22/7 * 8 kilometers= <span>25.14 kilometers

A full perimeter </span>of the circle, which is 25.14km,  has 360° angle. So 1km arc would be: 1km/ 25.14 km * 360°= 14.32°

The diameter of a circle is 8 ft. Find the circumferenceto the nearest tenth.
AURORKA [14]

Answer:

25.1 ft

Step-by-step explanation:

To solve for circumference is pretty simple. Just use the equation 2pi r (r=radius, radius is diameter divided by 2).

So essentially, apply to your calculator:

2(3.14)4=25.12

pretty simple! hope this helps!

Work the following pricing problems for services rendered. (For all calculations use hundredths.)
Lesechka [4]

Answer:

Hourly Rate = $12.22 per hour

Step-by-step explanation:

\text{Labor Time = }4\tfrac{1}{2}=4.5\thinspace{ hours}

Overhead Rate = 95%

Retail price of parts = $134.75

Total cost of job = $241.98

Cost of labor = Total cost - Retail price

                      = 241.98 - 134.75

                      = $107.23

Now, labor works for 4.5 hours and ears a total amount of $107.23

\implies\text{Amount earned in one hour or hourly rate = }\frac{107.23}{4.5}\\\\\implies \text{Hourly rate = }\$23.83\text{ per hour}

Now, Labor will get 95% overhead rate

⇒ The labor is getting 100% already but an overhead of 95% is also given

\text{So, Hourly Rate = }\frac{23.83}{1+0.95}\\\\\bf\implies\textbf{Hourly Rate = }\$12.22\textbf{ per hour}

a science quiz has eight multiple choice questions with five choices for each. Find the total number of ways to answer the quest
almond37 [142]

Answer:

390625

Step-by-step explanation:

The questions are all independent -- the answer on one question does not limit the number of possible answers on another question.

The quiz has 5 choices for each question, so there are

5\times5\times5\times5\times5\times5\times5\times5 ways to answer the quiz questions.

Notice that this could be written 5^8.  You could say that the number of ways to answer the questions is

number \, of \, choices^{number \, of \, questions}

Use a calculator to find 5^8
