Please help, is associated with angles. thank u :)

SOVA2 [1]

Answer:

Step-by-step explanation:

Because those lines are parallel, that means that the angle measuring 75 and the angle measuring 4x + 7 are alternate interior and by definition are congruent. Therefore,

75 = 4x + 7 and

68 = 4x so

x = 17

The sum of 10 consecutive integersstarting with 11, equals the sum of 5 consecutive integers, starting with

kaheart [24]

Answer: $\large\boxed{29}$

Step-by-step explanation:

The sum of 10 consecutive integersstarting with 11

= 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 = 155

Lets try 29:

29 + 30 + 31 + 32 + 33 = 155

Therefore our answer is:

$\large\boxed{29}$

The travel time for a college student traveling between her home and her college is uniformly distributed between 40 and 90 minu

love history [14]

Answer:

d. the travel time

Step-by-step explanation:

We are studying the travel time for the college student, which is between 40 and 90 minutes, distributed uniformly.

40 and 90 minutes are the intervals of the variable, and the variable is the travel time, which is random. Uniform is how the distribution is characterized, which means that each outcome(travel time beween 40 and 90 minutes) is equally as likely.

So the correct answer is:

d. the travel time

Please help I don’t understand this

enyata [817]

Answer:

d. √(1/(x+1))

Step-by-step explanation:

Just as operations can be performed on numbers and variables, so can operations be performed on functions. Here, you're asked to simplify the ratio of two functions.

$\displaystyle\left(\frac{g}{f}\right)(x)=\frac{g(x)}{f(x)}=\frac{\sqrt{x-1}}{\sqrt{x^2-1}}=\sqrt{\frac{x-1}{x^2-1}}$

At this point, you're supposed to know the factoring of the difference of squares:

$\displaystyle=\sqrt{\frac{x-1}{(x-1)(x+1)}}=\boxed{\sqrt{\frac{1}{x+1}}}$
