D^2 = (x2-x1)^2 + (y2-y1)^2
D =sqrt((10+5)^2 + (10-2)^2)
D P SQRT(15^2 + 8^2)
D = sqrt(225 +64)
D= sqrt(289)
D = 17
The distance is 17
Answer: The claim is not valid because the average is 2
Considering now that you have $150 subtract that from $1270. To see what you actually need to save. This would equal $1120. Divide $1120 by 80= 14 months So every 14 months, you save $80. 80 times 14= $1120. We got the $1120 by subtracting the $150 which you already had to make it easier.
The answer to that problem is c
So you are going to multiply the fractions by 10,000 to find the amount of money used on that item.
1/2 x 10,000 = 5,000 - FOOD
1/4 x 10,000 = 2,500 - BEVERAGES
1/10 x 10,000 = 1,000 - DECORATIONS
5,000 + 2,500 + 1,000 = 8,500
10,000 - 8,500 = MONEY SPENT ON STAFFING
= 1,500
