6.40 cms I hope This helped
A because the intersection point of the graph is 3x-8y=19
D)42 because u first have to multipy left to right then divide left to right then do the same thing with add and subtract
Find the area of the wheel:
Area of a circle is found using the formula:
Area = PI x r^2
9 inch would be the diameter, so the radius would be 9/2 = 4.5 inches.
The area would be 3.14 x 4.5^2 = 63.6 square inches.
Now divide the price by the area to get price per square inch:
Cost per square inch = 18.60 / 63.6 = $0.29 (rounded to the nearest cent)
You can find this by finding how much she would be paid per hour and then multiplying it by 6. So, you have $35 for the other days but on Sunday's it is that and then half of that added on just in one hour.
35+(1/2)(35)= 35+17.5=$52.5/hour
after you find this value you need to multiply it by 6 hours in order to be left with $315.
Now if you can just put a good word in for me at that job :)
