Srry but I can’t figure this one out
Answer: t = 340+22-10
Step-by-step explanation:
Hi, to answer this question we have to analyze each runner:
Norma takes 340 seconds to run the course.
Norma's time = 340
Jeremy takes 22 seconds longer to run a particular course than Norma. Since he takes seconds longer, we have to add that amount to Norma’s time:
Jeremy's time = Norma's time +22 = 340+22
Eleanor is a faster runner than Jeremy by more than 10 seconds. Since she is faster, we have to subtract 10 seconds to Jeremy's time to obtain Eleanor's time (t)
t = Jeremy's time - 10
t = 340+22-10 (seconds)
D =√(x2-x1)^2 + (y2-y1)^2
......._____________
5 =√(3-0)^2 + (k-1)^2
.......__________
5 =√3^2 + (k-1)^2
25 = 9 + (k-1)^2
16 = k^2 - 2k + 1
k^2 -2k - 15 = 0
(k - 5)(k + 3) = 0
k - 5 = 0.....or.......(k + 3) = 0
k = 5.........or.......k = -3
The smaller rectangle is like a smaller version of the big one, and 8 divided by 2 is four... so I think you need to divide 18 by 4, which is 4.5, so C is the answer
