<em><u>Question:</u></em>
Ana participated in a charity walk. She raised $0.25 for each 1/2 mile that she walked.The first day Ana walked 11 miles.The second day, she walked 14 miles.How much money did Ana raised?
<em><u>Answer:</u></em>
Ana raised $ 12.5
<em><u>Solution:</u></em>
From given question,
First day walk = 11 miles
Second day walk = 14 miles
<em><u>Let us first calculate the total distance she walked</u></em>
Total distance = first day walk + second day walk
Total distance = 11 + 14 = 25 miles
Thus she walked for 25 miles
Given that,
<em><u>She raised $0.25 for each 1/2 mile that she walked</u></em>
![\frac{1}{2} \text{ mile} = 0.25 \text{ dollars }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5Ctext%7B%20mile%7D%20%3D%200.25%20%5Ctext%7B%20dollars%20%7D)
Therefore, for 1 mile we get,
![\frac{1}{2} \times 2 \text{ mile} = 0.25 \times 2 \text{ dollars }\\\\1 \text{ mile } = 0.5 \text{ dollars }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%202%20%5Ctext%7B%20mile%7D%20%3D%200.25%20%5Ctimes%202%20%5Ctext%7B%20dollars%20%7D%5C%5C%5C%5C1%20%5Ctext%7B%20mile%20%7D%20%3D%200.5%20%5Ctext%7B%20dollars%20%7D)
Now calculate for 25 miles
![25 \text{ mile } = 25 \times 0.5 = 12.5 \text{ dollars }](https://tex.z-dn.net/?f=25%20%5Ctext%7B%20mile%20%7D%20%3D%2025%20%5Ctimes%200.5%20%3D%2012.5%20%5Ctext%7B%20dollars%20%7D)
Thus she raised $ 12.5
Answer:
10 kph
Step-by-step explanation:
Find the speed of the current of the river.
20/(20 - c) + 180/(20 + c) = 8
20(20 + c) + 180(20 - c) = 8(400 - c^2)
8c^2 - 160c + 800 = 0
8(c^2 - 20c + 100) = 0
8(c - 10)^2 = 0
c = 10
The speed of the current of the river is 10 km/hour.
Don’t take my word for it but if there’s no x then it might be undefined.
Sorry if I’m incorrect
Answer:
Only option (A) is incorrect.
So , true statements are (B), (C) &(D).
