Ana Participated in each charity walk she raise $.25 and each 1/2 That she walked the first day and I walked 11 miles a second day she walked 14 miles how much money did she raise

Answers

Question:

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?

Answer:

Ana raised $ 12.5

Solution:

From given question,

First day walk = 11 miles

Second day walk = 14 miles

Let us first calculate the total distance she walked

Total distance = first day walk + second day walk

Total distance = 11 + 14 = 25 miles

Thus she walked for 25 miles

Given that,

She raised $0.25 for each 1/2 mile that she walked

(1)/(2) \text{ mile} = 0.25 \text{ dollars }

Therefore, for 1 mile we get,

(1)/(2) * 2 \text{ mile} = 0.25 * 2 \text{ dollars }\n\n1 \text{ mile } = 0.5 \text{ dollars }

Now calculate for 25 miles

25 \text{ mile } = 25 * 0.5 = 12.5 \text{ dollars }

Thus she raised $ 12.5

The following table shows the length and width of two rectangles:Length Width
Rectangle A 3x + 2 2x - 1
Rectangle B x + 5 5x - 1


Which expression is the result of the perimeter of rectangle B minus the perimeter of rectangle A?
2x + 2
2x + 6
22x + 14
22x + 18

Answers

The perimeter of a rectangle is equal to two times the sum of the length and the width.
P=2(l+w)

Rectangle A:
l=3x+2 \n w=2x-1 \n \nP_A=2(3x+2+2x-1)=2(5x+1)=10x+2

Rectangle B:
l=x+5 \n w=5x-1 \n \nP_B=2(x+5+5x-1)=2(6x+4)=12x+8

The perimeter of rectangle B minus the perimeter of rectangle A:
P_B - P_A=12x+8-(10x+2)=12x+8-10x-2=\boxed{2x+6}

Answer:

2x+6
