Train A leaves the station traveling east at 55 mph, while train B leaves the station 45 minutes later traveling west at 70 mph.

Choose the equation below that represents the distance in miles between the two trains, D, as a function of T, the time in hours after train B has departed.
A.
D = 125T
B.
D = 125T + 41.25
C.
D = 125T - 41.25
D.

Answer: b)  D=125T+41.25

Step-by-step explanation:

Given,

speed of train A travelling east = 55 mph

speed of train B travelling west = 70 mph

time train A travelled while train B was at rest = 45 min or (\frac{3}{4})hr

so, Distance travelled by train A while train B was at rest = 55(\frac{3}{4} ) miles\\

                                                                                               = 41.25 miles

Now, after 'T' hour both the train will travel;

train A = 55T

train B = 70T

hence, the distance (D) between two train in miles will be;

⇒ D = 41.25 + 55T + 70T

⇒ D = 125T + 41.25

The following sets of numbers are possible side lengths of a triangle. Which of the following sets forms a Pythagorean triple?
sveta [45]
A Pythagorean triple means that when you do Pythagorean theorem, a, b and c will all be integer values. The largest number will always be put in for the 'c'.
Letter B is a Pythagorean triple.
28^2 + 45^2 = 53^2
784 + 2025 ?=? 2809
2809 = 2809

4. Starcraft 2 player Serral won 36 out of his last 45 matches in high-level play. Continuing with that level of competition, wh

Answer:

Starcraft

a) Probability of losing at most 2 games = 33%

b) Probability of winning at least 4 games = 67%

Step-by-step explanation:

a) To lose 2 out of 6 games, the probability is 2/6 x 100 = 33.333%

b) To win at least 4 games out of 6, the probability is 4/6 x 100 = 66.667%

c) Since Serral is playing 6 games, for her to lose at most 2 of the games is described as a probability in this form 2/6 x 100.  This shows the chance that 2 of the games out of 6 could be lost by Serral.  On the other hand, the probability of Serral winning at least 4 of the 6 games is given as 4/6 x 100.  It implies that there is a chance, 4 out of 6, that Serral would win the game.
