Answer:
Step-by-step explanation:
You haven't given the equation, but I can make one up.
Cost = 55 + 42*h
So let the cost = 265 dollars
265 = 55 + 42h Subtract 55 from both sides
210 = 42h Divide both sides by 42
210/42 = 42h/42
h = 5
He worked 5 hours.
Right angles are always 90 degrees. The answer is C.
Hope this helps.
1 hour = 60 minutes
15 minutes = (60/15) = 1/4th of an hour
1/4 = 0,25
<span>15 minutes is 25% of an hour</span>
Solving for x...

Times the

, both the numerator and denominator, by 8 to get the denominator to 16.
Times the

, both the numerator and denominator, by 4 to get the denominator to 16.
Then rewrite the problem,

now that the denominators are all the same, you can solve...
subtract the

from both sides
you should get

Multiply both sides by 16 (it'll cancel both the 16 out making it go away)
8x = 11
divide each side by 8 to have the x alone
<u>8x</u> = <u>11
</u> 8 8
<u>
</u> You should end with x =

or 1.375<u>

Answer:
The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object). When the absolute value of the scale factor is greater than one, an expansion occurs. When the absolute value of the scale factor is less than one, a compression occurs.
