10+8h=66
minus 10 both sides
8h=56
divide both sides by 8
h=7
worked 7 hours

To solve this question you need to make an equation including each variable: the extra $10, the $8 per hour (we'll represent hours as h) and the total amount of money, $66. Then simply solve the equation to get your final answer.

10 + 8h = 66
8h = 56 Subtract 10 from both sides
h = 7 Divide both sides by 8

In other words, he worked 7 hours.

A small college needs two additional faculty members: a chemist and a statistician. There are five applicants for the chemistry

Mrac [35]

Answer:

15 ways

Step-by-step explanation:

The events "choosing one out of 5 chemists" and "choosing one out of 3 statisticians" are independent, and, therefore, the number of ways that both positions can be filled is determined by the product of the number of ways that each event can occur:

$n=3*5 =15\ ways$

The college can fill these positions in 15 different ways.

Two figures are shown. EFJL is dialation of ABIK AB has a length of 12 and EF has a length of 3

Dimas [21]

The scale factor of dilation from AB to EF is 0.25

<h3>How to determine the scale factor of dilation?</h3>

The given parameters are:

EFJL is dilation of ABIK
AB has a length of 12
EF has a length of 3

From the above parameters, side lengths AB and EF are corresponding sides

This means that:

The scale factor of dilation (k) is

k = AB/EF

So, we have

k = 3/12

Evaluate

k = 0.25

Hence, the scale factor of dilation from AB to EF is 0.25
