Two trains on opposite tracks leave the same station at the same
time. One train travels at an average speed of 80 kilometers per
hour and the other travels at an average speed of 70 kilometers
per hour. How long after they leave the station will they be 50
km apart?

Answers

Answer 1

Answer: The answer is 1/3 hour, or 20 minutes

Step-by-step explanation:

The combined rate of separation is (80 km/hr + 70 km/hr) = 150 km/hr,

therefore they will be 1/3 of 150 km apart after traveling 1/3 of an hour.

pls mark brainliest

The number of sides in the building is 6

6 sides

Given :

Melissa is walking around the outside of a building that is in the shape of a regular polygon.

She determines that the measure of one exterior angle is 60 degree

We know that the measure of exterior angle of any regular polygon is 360 degrees.

one exterior angle is 60°

The number of sides of regular polygon is total exterior angle / one exterior angle

Number of sides of regular polygon =[tex]\frac{360}{60}=6[/tex]

So, the building have 6 sides .

Write the equation of the line in slope-intercept form for the line with a slope of 13 and a y - intercept of (0, 4)

Answers

Answer:

y=13x+4

Step-by-step explanation:

y-y1=m(x-x1)

y-4=13(x-0)

y-4=13(x)

y-4=13x

y=13x+4

Answer:

y=13x + 4

Step-by-step explanation:

Hi there!

We want to write the equation of the line in slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept

We are given that the line has a slope of 13, and a y intercept of (0,4)

As we are directly given the slope and the y intercept, we can substitute these values into the formula to find the equation of the line

First, substitute 13 as m

y=13x + b

Now, as stated earlier, the value of b is the value of y at the y intercept.

We were given that the y intercept is (0,4); the value of y at this point is 4

Substitute 4 as b into the equation

y=13x + 4

Hope this helps!

Step-by-step explanation

3=e and 5=f (but I guess u accidentally put a plus sign)

so 2e= 6 and 3f=15, and 6-15=-9 so this checks out

Next e=3 and 3f=15 (that 5 in the second problem should be an f)               and 3+15-18 again is checks out so 3,5 must be correct yada yada yada goodnight.

John, Kevin, and Andrew are counting their pennies. John has three times as many pennies as Kevin. If John and Andrew put their pennies in the same container, they'll have 266 pennies. However, if Kevin and Andrew put their pennies together, they will have 198 pennies. How many pennies does John have?

Answers

Answer:

102 pennies

Step-by-step explanation:

Let the number of pennies owned by John, Kevin, and Andrew be J , K and A respectively

Given that John has three times as many pennies as Kevin then

J = 3K

If John and Andrew put their pennies in the same container, they'll have 266 pennies then

J + A = 266 Since J = 3K

3K + A = 266

However, if Kevin and Andrew put their pennies together, they will have 198 pennies

K + A = 198

Subtract K + A = 198 from 3K + A = 266

2K = 68

K =68/2 = 34 pennis

J = 3K J = 3 * 34

= 102 pennies

John has 102 pennies
