Answer:
45 J
Step-by-step explanation:
Just plugged into the work force formula got 45 jules
<h2>
362.8 meter^2 </h2>
(rounded by the nearest tenth .79>.8)
<h3 />
<u>Formula:</u>
A=2⋅π⋅r⋅h+2⋅π⋅r^2
<u>Equation:</u>
<h3>
2⋅ 3.14⋅ 5.3⋅ 5.6+ 2⋅ 3.14⋅ 5.3^2 =</h3><h2>
362.8 m^2</h2>
The correct selling price is about $20, and the likely mistake was the manager multiplied the $12 by .67 (the 67%), got about 8, and took that as the price instead of adding it to the original 12, which is what they were supposed to do.
First you want to add all of those together.
12 + 4 + 6 + 2 = 24
So there are 24 miles in total.
Next, it says she biked 12 miles so you make a fraction.
12 / 24 which can be reduced to 1/2.
She spent one half of the total distance biking.
Hope this helps!
