Answer:
620.14
Step-by-step explanation:
Original Equation:
![\frac{4y}{1.025^4}+y-2y(1.05)^2=1500](https://tex.z-dn.net/?f=%5Cfrac%7B4y%7D%7B1.025%5E4%7D%2By-2y%281.05%29%5E2%3D1500)
Calculate exponents
![\frac{4y}{1.103812890625}+y-2y(1.1025)=1500\\](https://tex.z-dn.net/?f=%5Cfrac%7B4y%7D%7B1.103812890625%7D%2By-2y%281.1025%29%3D1500%5C%5C)
Simplify:
![3.6238025791990193084270042653997y + y - 2.205y = 1500](https://tex.z-dn.net/?f=3.6238025791990193084270042653997y%20%2B%20y%20-%202.205y%20%3D%201500)
Add like terms
![2.4188025791990193084270042653997y \approx 1500](https://tex.z-dn.net/?f=2.4188025791990193084270042653997y%20%5Capprox%201500)
Divide both sides by 7.012
![y\approx 213.91](https://tex.z-dn.net/?f=y%5Capprox%20213.91)
![y\approx620.14](https://tex.z-dn.net/?f=y%5Capprox620.14)

4
Step-by-step explanation: 2+2=4
because imagine if u had 2 dollars and your mom gave u another 2 dollars u will have 4 dollars
Two sevenths over two fifths = five over seven mile per hour
The unit rate is 5 over 7 miles per hour
<em><u>Solution:</u></em>
Given that, Suzanna walked two over seven of a mile in two over five of an hour
We have to find the unit rate in miles per hour
Unit rate means number of miles covered in 1 hour
From given information,
Two over seven of a mile in two over five of an hour
Which means,
![\frac{2}{7} \text{ miles } = \frac{2}{5} \text{ hour }](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B7%7D%20%5Ctext%7B%20miles%20%7D%20%3D%20%5Cfrac%7B2%7D%7B5%7D%20%5Ctext%7B%20hour%20%7D)
![\text{ So she covered } \frac{2}{7} \text{ miles in } \frac{2}{5} \text{ hour }](https://tex.z-dn.net/?f=%5Ctext%7B%20So%20she%20covered%20%7D%20%5Cfrac%7B2%7D%7B7%7D%20%5Ctext%7B%20miles%20in%20%7D%20%5Cfrac%7B2%7D%7B5%7D%20%5Ctext%7B%20hour%20%7D)
To find for number of miles covered in 1 hour, divide the ![\frac{2}{7} \text{ by } \frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B7%7D%20%5Ctext%7B%20by%20%7D%20%5Cfrac%7B2%7D%7B5%7D)
![\text{Unit rate in miles per hour } = \frac{\frac{2}{7}}{\frac{2}{5}}\\\\\text{Unit rate in miles per hour } = \frac{2}{7} \times \frac{5}{2} = \frac{5}{7}](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20rate%20in%20miles%20per%20hour%20%7D%20%3D%20%5Cfrac%7B%5Cfrac%7B2%7D%7B7%7D%7D%7B%5Cfrac%7B2%7D%7B5%7D%7D%5C%5C%5C%5C%5Ctext%7BUnit%20rate%20in%20miles%20per%20hour%20%7D%20%3D%20%5Cfrac%7B2%7D%7B7%7D%20%5Ctimes%20%5Cfrac%7B5%7D%7B2%7D%20%3D%20%5Cfrac%7B5%7D%7B7%7D)
Two sevenths over two fifths = five over seven mile per hour
Thus unit rate is 5 over 7 miles per hour
The Pythagorean theorem tells you the other leg is
... √(c² - a²) = √(4.2² -2.9²) = √9.23 ≈ 3.038 ≈ 3.0
