The perimeter of a rectangle = 2(L+B)
therefore, 40 = 2(L+B)
40/2 = L+B
20 = L+B
3L+B = 20
B= 20/4
= 5
L= 5*3
= 15
i hope this helps
I don’t fully understand but you might be able to do something like
70t -30t = d, but I think that would be how much farther they are from the start point, but assuming they are driving in a straight line or would be a right triangle, so maybe The square root of 70t^2 + 30t^2
Answer:
x=5.9
Step-by-step explanation:
(a) A 1/7 (1 in 7) chance because there are 7 days in a week and you only can get get 1. (b) A 1/12 (1 in 12) because there are 12 months in a year and you can only get 1. (c) The probability of you getting a Monday is 1/7, 14.28%, or 0.1428. The probably of you getting a November is 1/12, 8.33333%, or 0.0833333. You are more likely to get a Monday than a November.
