Answer:
$8.8 per hour
Step-by-step explanation:
Well, the equation is simple.
Time (hours) * Money (per hour) = Total
We know the time he worked for and the total amount he earned, so just replace in this equation and find the unknown number
12.5 * money = 110
To find the money he earns per hour we should just simply divide the total amount he earned by the hours he spent working
money = 110/12.5
money = 8.8$
You can also check it out to make sure it's correct.
If he earns 8.8$ per hour and worked for 12.5 hours how much he'll earn? Let's find out
8.8 * 12.5 =?
8.8 * 12.5 = 110, the same total amount so our solution must be correct.
That is a 30 60 90 triangle
The "short" side (DE) equals the middle side (FE) times (1 / sq rt(3))
short side = 8 * sqrt(3) * (1 / sq rt(3) = 8
Hypotenuse (DF) is 2 times the short side which equals 16.

The width is 18.
step by step:
1. 2 lengths are 20 which is 20+20 that's 40.
2. 76-40= 36
3. Two widths are 36 cm.
4. so do 36÷2 and that equals 18
Answer:
The graph has a closed circle.
–7 is part of the solution.
Step-by-step explanation:
Given
Required
Select 3 options from the given list of options
Subtract 22 from both sides
Swap positions of the expression; Note that the inequality sign will change
This means <em>x less-than-or-equal-to negative 7</em>
<em></em>
There are two options left to select;
The inequality sign in implies that the graph has a close circle.
Inequality signs such as 
and 
signifies a close circle
There is only one option left to select;
Lastly;
Split the expression into two
We have:
or 
Because 
,
Then, -7 is also a part of the solution
