Answer:

y = 25 and x = 10

Step-by-step explanation:

the angles on top and on bottom are equal so...

5y - 25 = 100

5y - 25 <em>+ 25</em> = 100 <em>+ 25</em>

5y = 125

5y/5 = 125/5

y = 25

Every line is 180 degrees so we know that if the top and bottom angles are 100 then the other angles need to equal 80

11x - 30 = 80

11x - 30 <em>+ 30  </em>= 80 <em>+ 30</em>

11x = 110

11x/11 = 110/11

x = 10

Answer: x=10 and y=25

Step-by-step explanation:

ok, so since we know straight angles=180 degrees, so since one part=100, the other smaller angle=80. This means that 11x-30=80 and 5y-25=100. 11*10=110, and 110-30=80, so x=10. 5*25=125, and 125-25=100, so y=25. And lol. me too. When I used to do these problems, I was stuck for a very, very long time. Just try to use logic most of the time.

A mule deer can run 1/4 of a mile in 25 seconds. At this rate which expression can be used to determine how fast a mule deer run
Tanzania [10]
Ok so this might be a bit confusing but I hope u understand it. Because the problem is in seconds, I tried to stick to seconds. In an hour there are 60 minutes and in those 60 minutes there are 3,600 seconds. Now in 25 seconds the mule deer can run 1/4 mile. So think for a second how many seconds it would take for it run a full mile. If u do the math then u would get 25*4 which is 100 seconds to run a full mile. Going back to our 3,600 seconds, all u have to do is divide it by 100 to get the miles. So 3,600/100 is 36. The mile deer runs 36 miles in an hour. I hope this was of help to u

ANSWER FAST MY DUDEZ!<br> What is the value of x in the equation <br> 1.8- 3.7x = 4.2x + 0.3
Inessa [10]

1.8- 3.7x = 4.2x + 0.3

Move 4.2x to the other side

Sign changes from +4.2x to -4.2x

1.8-3.7x-4.2x= 4.2x-4.2x+0.3

1.8-3.7x-4.2x= 0.3

1.8-7.9x= 0.3

Move 1.8 to the other side

Sign changes from +1.8 to -1.8

1.8-1.8-7.9x= 0.3-1.8

-7.9x= 0.3-1.8

-7.9x= -1.5

divide both sides by -7.9

-7.9/-7.9x= -1.5/-7.9

x= 0.18987341

Answer: x= 0.18987341

M=undefined, x-int=(3,0)
kumpel [21]

Answer:

  x = 3

Step-by-step explanation:

Maybe you want the equation of the line.

__

A vertical line has undefined slope. Its equation is of the form ...

  x = constant

In order for the line to go through a point with an x-coordinate of 3, the constant must be 3.

  x = 3 . . . . equation of the line

Identify the parameters in the following situation. When Jackie is camping, she sees 6 shooting stars every hour, on average. Wh
andrey2020 [161]

Answer:

The probability that she sees exactly 4 shooting stars in the next hour is 0.13

Step-by-step explanation:

An assumption is made that she see the shooting stars of 6 every hour based on a poisson distribution.

P(X = x) = \frac{e^{-m} m^{x} }{x!}

where m is the average per hour = 6

P(X = x) = \frac{e^{-m} m^{x} }{x!}\\P(X = 4) = \frac{e^{-6} 6^{4} }{4!}\\P(X = 4) = \frac{0.002478752 * 1296 }{4!}\\P(X = 4) = \frac{3.212462592}{24}\\P(X = 4) = 0.133852618\\P(X = 4) = 0.13
