Answer:
Step-by-step explanation:
<u>Payment is</u>
<u>Divide both by 4/5 to find payment per hour</u>
- 7.20 ÷ 4/5 ⇔ 4/5 ÷ 4/5
- 7.20 ÷ 0.8 ⇔ 1
- 9.00 ⇔ 1
9.00 unit of money per 1 hour
Answer:
33.14 ft^2
Step-by-step explanation:
First find the area of the circle
The diameter is 20 ft so the radius is 1/2 of the diameter of 20*1/2 = 10 ft
A = pi r^2 = pi ( 10)^2 = 100 pi
The central angle is 38
That is a fraction of the circle, which is 360 degrees
38/360 = 19/180
Multiply the fraction of the circle by the area
19/180 * 100 pi
19/9 * 5 pi
Using 3.14 for pi
33.144444
To the nearest hundredth
33.14 ft^2
For the part b of the question please find the attached image.
When increasing a percentage I usually just turn the percentage to a decimal. So, let's say you have 100 gallons of gas and it'll get an increase by 20%, just multiply 100 by .20 and you'll get 20, then add 20 to 100 to see what you'll have after. In this case, 15% would be .15, just multiply 22 by .15 to see how much the increase is, then add what you get to 22.
