1. He worked 10 hours + 15 hours = 25 hours
He earned $280 for 25 hours of work.
The rate per hour is $280/25 hours = $11.20/hour

2. You need to find 6% of $32,345.
To find a percent of a number, multiply the percent by the number.
To change the percent into a decimal, move the decimal point two places tot he left.
6% of $32,345 = 6% * $32,345 = 0.06 * $32,345 = $1,940.70

3. flat paint: 33 gal
gloss paint: 57 gal
Total paint = 33 gal + 57 gal = 90 gal
Ratio of gloss to total = 57:90

A supervisor finds the mean number of miles that the employees in a department live from work. he finds x overbar = 29 and s = 3
V125BC [204]

A supervisor finds the mean number of miles that the employees in a department live from work is 24. Then the correct option is B.

<h3>What is a z-score?</h3>

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The z-score is given as

z = \dfrac{x-\mu }{s}\\

x = 29

s = 3.6

z = 1.5

Then the mean will be

1.5 = \dfrac{29 - \mu }{3.6}\\\\\mu = 29 - 5.4\\\\\mu = 23.6 \approx 24

More about the z-score link is given below.

PLEASE HELP

Answer:

12\sqrt{3} feet

Step-by-step explanation:

In a 30-60-90 triangle, the ratios of the side lengths of the triangle is 1:\sqrt{3} :2

Where 1 is the shortest leg, root(3) is the longer leg, and 2 is the hypotenuse.

First we can set x equals to the length of the original pole, and so the shorter leg has a length of x/3 and using the ratio of side lengths, we can find that:

\frac{x}{3} * \sqrt{3} = \frac{\sqrt{3} x}{3} = 12

Solving for x, we find that

x=\frac{36}{\sqrt{3} } = \frac{36 * \sqrt{3} }{\sqrt{3} * \sqrt{3} } = \frac{36  \sqrt{3} }{3} = 12\sqrt{3}

So the length of the original pole would be 12\sqrt{3} feet

Oxana [17]

x = number of adult tickets

y = number of children tickets

9x + 6y = 1053

x+y = 127 so x = 127 - y

replace x = 127 - y into 9x + 6y = 1053

9(127 - y) + 6y = 1053

1143 -9y + 6y = 1053

-3y = 1053 -1143

-3y = -90

y = 30

x = 127 - 30

x = 97

answer: 97 adults and 30 children
