A train travels at a constant speed of 35 miles per hour how long does it take the train to travel 490 miles
charle [14.2K]
We have to write a proportion. We put 35 over 60 to show that 35 miles can go in every 60 minutes. Next to it we write another fraction and put 490 over x because we are trying to find how many MINUTES first. we multiply 490 by 60 which is 29400. Now we divide that by 35. we get 840 minutes. Now we convert this into hours by dividing it by 60 because there are 60 minutes in an hour. 840 divided by 60 is 14 hours. The answer is 14 hours.

PLZ HELP I WILL GIVE 20 POINTS WHOEVER ANSWERS FIRST:
nalin [4]

Answer:

-2

Step-by-step explanation:

So to find slope you just subtract y^1 - y^2 and divide it by x^1 - x^2

The first point is (2, 1)

The second is (0, 5)

1 is our y^1 and 5 is our y^2

1 - 5 = -4

2 is our x^1 and 0 is our x^2

2 - 0 = 2

So our slope is -4/2, reduced its -2

I hope this helped, please mark Brainliest, thank you!

I just need 6, 7, 8, 9, and 10. Please help me if you know how to do this..
goblinko [34]

Answer:

Step-by-step explanation:

#6  

a       n

---- = ----    Solve for a.  Note that if we multiply both sides of this equation by

m       p                                     n

                  m, we get a = m * ----

                                                  p

                                                                                    m*n

                    and this simplifies to a = mn/p or  a = ---------

                                                                                       

#7     Solve mx = np for x.  We want to isolate x on the left side.  Dividing

both sides by m isolates x on the left and adds the divisor m on the right:

                            np

mx = np  =>  x = ------

                              m

#8    Solve c - x = d + r  for x       We want -x alone on the left side.  Accomplish this by subtracting c from both sides, obtaining:

-x = d + r - c.       Now multiply both sides by -1, obtaining x = -d - r + c

The width of the rectangle is 75% of its length, the length is 24, what's the area?
lapo4ka [179]
S = a * b  where a - <span>length and b - width
a = 24
b = 0.75 * a
S = 24 * 24 * 0.75 = 432</span>
