Let the distance of the first part of the race be x, and that of the second part, 15 - x, then
x/8 + (15 - x)/20 = 1.125
5x + 2(15 - x) = 40 x 1.125
5x + 30 - 2x = 45
3x = 45 - 30 = 15
x = 15/3 = 5
Therefore, the distance of the first part of the race is 5 miles and the time is 5/8 = 0.625 hours or 37.5 minutes
The distance of the second part of the race is 15 - 5 = 10 miles and the time is 1.125 - 0.625 = 0.5 hours or 30 minutes.
We have been given that Layana’s house is located at 
on a map. The store where she works is located at 
.
We are asked to find the distance from Layana’s home to the store
We will use distance formula to solve our given problem.
Let us convert our given coordinates in improper fractions.
Now we will use distance formula to solve our given problem.
Upon substituting coordinates of our given point in above formula, we will get:
Therefore, the distance from Layana's home to the store is 4 units and option A is the correct choice.
R2+15r+36=0 the answer is r=6
Answer: I don't see what your talking about here, so I can't help you.
Step-by-step explanation:
Oh ok. So I think that x is 83. Because I did this 630-100-121-106-112-108=83. And then I did 630/6 and got 105 and thats the mean.
