Answer:
2.85
Step-by-step explanation:
You will pay $2.85 for a item with original price of $3.80 when discounted 25%. In this example, if you buy an item at $3.80 with 25% discount, you will pay 3.80 - 0.95 = 2.85 dollars.
A cube is a 3 dimensional object with 6 square faces. All its sides are the same length, there fore the volume is equal to
![s^3](https://tex.z-dn.net/?f=s%5E3)
where s is the side length.
![s^3 = \frac{27}{64}](https://tex.z-dn.net/?f=s%5E3%20%3D%20%20%5Cfrac%7B27%7D%7B64%7D%20)
To solve for s, take the cube root of both sides.
![\sqrt[3]{s^3}= \sqrt[3]{ \frac{27}{64} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bs%5E3%7D%3D%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B27%7D%7B64%7D%20%7D%20%20)
![s= \frac{3}{4}](https://tex.z-dn.net/?f=s%3D%20%5Cfrac%7B3%7D%7B4%7D%20)

Answer:
The third one of the first question.
Answer:
They are correct
Step-by-step explanation:
Answer:
Revolution = 127.24 revolutions
Step-by-step explanation:
<em><u>Circumference of the tire = πD</u></em>
Where D = 15 inch
So,
C = 15π = 47.1 inch
<u><em>In feets:</em></u>
47.1 inch = 3.93 feet.
So, <u>one revolution = 3.93 feet</u>
<u><em>Travelling 500 feet will make the following revolutions:</em></u>
Revolution = 500 feet/3.93 feet
Revolution = 127.24 revolutions
