The common factor is 7 so its
7(2x - 3)
He ran 2700 mins total in 12 weeks.
He ran 1800 laps in this time frame.
= 1800/2700 = 2/3 lap per minute x 60 min/hour
= 40 laps/hour average

Answer:
0.7857
Step-by-step explanation:
Given the following :
Number of Easy faces = 4
Number of challenging faces = 7
Number of extreme faces = 3
Total number of faces or route = (4 + 7 + 3) = 14
If one route is chosen at random, the probability of not choosing an extreme route will be :
Probability = (required outcome / Total possible outcomes)
P(not choosing an extreme route) = 1 - P(choosing an extreme route)
P(choosing an extreme route) = 3 / 14 = 0. 2143
Hence,
P(not choosing an extreme route) = 1 - 0.2143
= 0.7857
Answer:
17 feet
Step-by-step explanation:
Let x represent the shorter leg of the triangle. Then the longer leg is (2x-1) and the area is ...
A = (1/2)bh = (1/2)(x)(2x-1) = 60
2x^2 -x = 120 . . . . multiply by 2 and simplify
2x^2 -x -120 = 0 . . . . subtract 120
(x -8)(2x +15) = 0 . . . . factor. The positive solution is x=8.
The square of the hypotenuse is ...
hypotenuse^2 = x^2 + (2x -1)^2 = 8^2 + 15^2 = 289
hypotenuse = √289 = 17
The length of the hypotenuse is 17 feet.
