Answer:
B, H
Step-by-step explanation:
The electrician charges 45 dollars per hour and 30 at the beginning. We are multiplying the hours, h, by 45 to get 45h. We add 30 to get C=45h+30
Jerome will always earn 75 dollars, but he also gets 10 percent commission, which is 0.10.
Answer:
<h3>A) </h3>
First were going to put our numbers in perspective.
÷ 
But to find the improper fraction, we have to <em>cross multiply</em> these numbers.
×
<em>7 x 5 = 35. </em>
<em>4 x 8 = 32.</em>
Now we have our<em> improper fraction </em>is 
<h3>B) </h3>
To turn our improper fraction into a <em>mixed number</em>, we will use <em>division</em>.
We know that the 32 can only go into 35 <u><em>one</em></u> time. We also know that the bottom number <em><u>always</u></em> stays the same. So our equation will look somewhat like this.

Now to fine the top number we will have to<em> subtract 35 from 32</em> because we already know that 32 can go into 35 <u><em>one</em></u> time, so <em>35 - 32 = 3</em>. So are mixed number will look like this.

This is our <em>answer!</em>

we have

Remember that
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents
so

Answer:
V = 486
, or approx. 1,526.814
Step-by-step explanation:
V =
*r²*(h/3)
plug in the numbers: V =
* (9)² * (18/3)
simplify: V =
* 81 * 6
simplify: V = 486
, or approx. 1,526.814
