<span>If One full revolution is 8 seconds when the dent is 6.5 inches above floor and the dent at the bottom is 0.5 inches above floor, the answer will be half a revolution or 4 seconds when the dent is at the bottom..</span>
We have to evaluate the unit rate for 1 Apple for $0.19.
The formula for unit rate is shown below.
![\text{Unit rate }= \frac{\text{Cost of the prodcut}}{\text{Number of units}}](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20rate%20%7D%3D%20%5Cfrac%7B%5Ctext%7BCost%20of%20the%20prodcut%7D%7D%7B%5Ctext%7BNumber%20of%20units%7D%7D)
Now, we have been given the cost of the apple is $0.19 and the number of unit is 1. Hence, using the above mentioned formula, the unit rate is given by
![\text{Unit rate }= \frac{0.19}{1}\\ \\ \text{Unit rate }= 0.19](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20rate%20%7D%3D%20%5Cfrac%7B0.19%7D%7B1%7D%5C%5C%0A%5C%5C%0A%5Ctext%7BUnit%20rate%20%7D%3D%200.19)
Therefore, the unit rate is 0.19 dollars per apple.
The equivalent expressions are 6y + 4 and 11y + 16
<h3>How to determine the equivalent expressions?</h3>
<u>Expression (A)</u>
We have:
2y + 4(y + 1)
Open the bracket
2y + 4y + 4
Evaluate the like terms
6y + 4
<u>Expression (B)</u>
We have:
9y + 6 + 2(5 + y)
Open the bracket
9y + 6 + 10 + 2y
Evaluate the like terms
11y + 16
Hence, the equivalent expressions are 6y + 4 and 11y + 16
