Find the values of x and y. <br><br> Please show steps

miv72 [106K]

X: 90 degrees. y: 43 degrees

We know that x is a right angle. The way we find y is to add 47 + 90 which gives us 137. We also know that a right triangle adds up to 180. So, we subtract 137 from 180. This means that y would be 43 degrees.

If 2x+5=8x, then 12x=?

mr_godi [17]

Answer:

$\boxed{10}$

Step-by-step explanation:

$2x+5=8x$

$\sf Subtract \ 8x \ from \ both \ sides.$

$2x+5-8x=8x-8x$

$-6x+5=0$

$\sf Subtract \ 5 \ from \ both \ sides.$

$-6x+5-5=0-5$

$-6x=-5$

$\sf Divide \ both \ sides \ by \ -6.$

$\displaystyle \frac{-6x}{-6} =\frac{-5}{-6}$

$\displaystyle x =\frac{5}{6}$

$\sf Evaluate \ 12x.$

$\displaystyle 12 \cdot \frac{5}{6} =\frac{60}{6} =10$

On average, mary has noticed that 18 trains pass by her house daily (24 hours) on the nearby train tracks. what is the probabili

Ludmilka [50]

The probability that exactly 1 train will pass Mary's house is 0.00889.

According to the given question.

On average, 18 trains pass by Mary's house daily i.e. in 24 hours.

As, we know that "Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event".

Therefore,

The probability that exactly one train will pass Mary's house in a 3 hour period

= $\frac{^{18C_{1} } }{^{24} C_{3} }$

$= \frac{\frac{18!}{1!\times17!} }{\frac{24!}{3!\times 21!} }$

$= \frac{18}{\frac{24\times23\times22}{3\times2\times1} }$

$=\frac{18}{8\times23\times\ 11}$

= 18/2024

= 0.00889

Hence, the probability that exactly 1 train will pass Mary's house is 0.00889.
