PLZ, QUICKLY IT IS HOMEWORK Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the other train travels at 80 mph. How long after they leave the station will they be 50 km apart?
Answer:
20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.
Step-by-step explanation:
The given is,
One train travels at an average speed of 80 km/hr
The other travels at an average speed of 70 km/hr
Step:1
Formula to calculate the distance traveled by two trains,
Distance traveled by two trains = (Rate of speed of train one +
Rate of speed of other train) × Time
From the given the above equation becomes,
Let, h = Time taken to each the distance
50 = ( 80 + 70 ) h
50 = (150) h
= 0.3333 hours
= ( 0.333 × 60 ) ( ∵ 1 hr = 60 minutes )
h = 20 minutes
Step:2
Check for solution,
From equation (1),
50 = ( 80+70 ) (0.3333)
50 = (150)(0.3333)
50 = 50
Result:
20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart.

Answer:
No, It is not true
Step-by-step explanation:
First of all, we should have a number in the tenths place, and we don't.
Also, in the hundredths place, we should have 9, not 4.
And finally, the answers should be 0.195, not 0.042.
Answer:
This is False
You want to add it up as if there wasnt any decimal than you want to put the decimals back 3 spots
0.025 + 0.17= 0.195

Answer:
Shaded area is 55 units²
Step-by-step explanation:
Ignoring the white cutout, we have a rectangle of length 10 and width 7 (count the squares in each direction). The area of this larger rectangle is
(10 units)(7 units) = 70 units². The white area that we previously ignored has dimensions 3 by 5 units, and thus an area of 15 units²
Subtract the latter from the former, obtaining the net area
70 units² - 15 units² = 55 units²

Answer:
x = 3
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the triangle , then
15x + 5 + 22x + 4 = 120
37x + 9 = 120 ( subtract 9 from both sides )
37x = 111 ( divide both sides by 37 )
x = 3

Here is to my last q
Answer: D (Mean is 85)
Explanation:
"The list below shows the quiz scores for a group of students.
95, 80, 80, 85, 80, 85, 90"
The choices talk about median and mode so we find those first:
Median: find by taking which is the middle number when the data is from low to highest
1) rearrange them from low to high
80, 80, 80, 85, 85, 90, 95
2) find middle number
80, 80, 80, 85, 85, 90, 95
The median is 85
Mean: mean is the average of all numbers. Find by adding numbers and dividing by amount of numbers
1) add 80, 80, 80, 85, 85, 90, 95 and get 595
2) There are 7 total numbers so do 595/7 = 85
The mean is 85
D is the correct answer
why?
A is wrong because they are 85 not 80
B is wrong because it is 85 not 80
C is wrong because it is 85 not 80
D is right because it is 85!
