Answer:
207m
Step-by-step explanation:
We apply the cosine rule to find the distance between the other two subs.
Let this distance be x, then the cosine rule gives:
![{x}^{2} = {360}^{2} + {250}^{2} - 2 \times 360 \times 250 \cos(34)](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%3D%20%20%7B360%7D%5E%7B2%7D%20%20%2B%20%20%7B250%7D%5E%7B2%7D%20%20-%202%20%5Ctimes%20360%20%5Ctimes%20250%20%5Ccos%2834%29%20)
We simplify to get:
![{x}^{2} = 192100 - 180000(0.8290)](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%3D%20192100%20-%20180000%280.8290%29%20)
Simplify
![{x}^{2} =42873.2369](https://tex.z-dn.net/?f=%7Bx%7D%5E%7B2%7D%20%20%3D42873.2369)
Take square root;
![x = \sqrt{42873.2369}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Csqrt%7B42873.2369%7D%20)
![x = 207.06](https://tex.z-dn.net/?f=x%20%3D%20207.06)
To the nearest meter the distance between them is 207m
Answer:
Costco has the better deal.
Step-by-step explanation:
Find the unit rate for Costco:
<em>Remember, the unit rate is when one of the numbers in a ratio is 1.</em>
<em />
Toilet paper : Price
6 : 4.99
(divide both sides by 6)
1 : .83
<em>Remember to round to the nearest hundredth place because money only goes two places after the decimal point.</em>
<em />
Therefore, 1 roll of toilet paper at Costco costs 83 cents.
Find the unit rate for Target:
Toilet paper : Price
8 : 6.99
(divide both sides by 8)
1 : .87
Therefore, 1 roll of toilet paper at Target costs 87 cents.
Conclusion:
.83 < .87
In conclusion, Costco has a better deal because toilet paper is cheaper per roll.
