A train leaves Chicago for Los Angeles going a constant rate of 40 MPH. Two hours later, another train leaves Chicago for Los Angeles on the same track as the first going a constant rate of 60 MPH.
1. When will the 2nd train catch up to the first train?
2. How many miles will the trains have traveled when they meet?
Answer:
1 . 4 hrs , 2 . total 400 miles because the first train had travelled 160 miles and 2nd one had travelled 240 miles
Step-by-step explanation:
in 1. use relative motion concept I. e. you sir on 1st train and put velo. of same mag. and in oppo. direction on the train on which you have sit and do the same with the velocity only with 2nd train means you stop the train on which you are sitting and put the velocity of the train on which you are sitting on 2nd train but in oppo. direction , so now the relative velocity comes out to be 20 mph and then apply formula time = Srel / Vrel and here we can find S rel by multiplying the velo. of 1st train by given time I. e. 2 hrs and in 2. multiply the time calculated by us by the velocity of both trains and by which you get the dist. travelled by both trains and then add them to get final answer.
what is the distance between points (4,0) and (-2,-3)
Hi! I'm happy to help!
To solve this equation, we need to find how much distance is between the y coordinates, how much distance is between the x coordinates, and then use the Pythagorean Theorem.
Let's start with finding the distance between the x coordinates. The first x coordinate is 4, and the second is -2. This means that the distance in x is 6.
Next, we need to find how much distance is between the y coordinates. The first y point is at the y coordinate 0, and the second is at the y coordinate -3. This means that the distance in y is 3.
Now we use the Pythagorean Theorem, which says that a²+b²=c²
A and b refer legs of a right triangle, and c refers to the hypotenuse (longest side) of the right triangle. Imagine the two points on a line, the direct distance is the c, and the y and x movements alone are a and b.
Let's say x is a, and y is b. Let's insert our values:
6²+3²=c²
36+9=c²
45=c²
To find c, we need to find the square root of 45
√45
6.708203...
Rounds to about 6.7 in tenths.
So, the distance between those two points is about 6.7.

On a certain trip, a traveler is driving at a constant rate of 85 km/hour. At that rate, the number of minutes needed to complete the last 43 kilometers of the trip is between
a. 20 and 25
b. 25 and 30
c. 30 and 35
d. 35 and 40
e. 40 and 45
Answer:
30 and 35
Step-by-step explanation:
Distance covered of 85km=1hour=60minutes
Distance covered of 1km=60minutes/85km
Distance covered of 43km=60mins/85km × 43mins
= 30.35mins

Plugging all the values,
[tex]p=\frac{94-43}{94}[/tex] × [tex]100[/tex]

Therefore, the percent change from 94 to 43 is 54.25%
What is the value of U. 51degrees, 79degrees and u.
Hi ;-)
[tex]u+51^o=79^o\\\\u=79^o-51^o\\\\\huge\boxed{u=28^o}[/tex]
The required equation is,
→ 51° + U = 79°
Now we should,
find the required value of U.
→ 51° + U = 79°
→ U = 79° - 51°
→ [U = 28°]
Let's check whether the required value of U is correct or incorrect,
→ 51° + U = 79°
→ 51° + 28° = 79°
→ 79° = 79°
→ LHS = RHS
Hence, 28° is the required value of U.

4. Explain the difference between (-5)2 anc
-52.
Answer: The answer is super easy bc it is only a small difference. The outcome of (-5)^2 will be 25 meanwhile -5^2 will have an outcome of -25
Answer:
(-5)² = 25 -5² = -25
Step-by-step explanation:
When we have (-5)², then -5 gets multiplied to itself. When there are two negative numbers, the answer is always positive. ex. (-5 x - 5 = 25)
(-5)² = 25
-5 x 5 = -25
-5² = -25

Question in photo. Please explain it too
=============================================================
Explanation:
Let's say that all of the 11 songs are 2 minutes each, which is just a bit under the "2 minute 1 second" mark of the shortest song. I'm going for the lowest time value possible and rounding to the nearest minute.
This would mean the entire album is 2*11 = 22 minutes long. This is the lower bound or the shortest the album can be.
If we go to the other end of the spectrum, and say each song is 6 minutes (I rounded "5 minutes 37 seconds" up to the nearest minute), then the album is now 6*11 = 66 minutes long. This is the upper bound or the longest the album can be.
While we don't know how long the album is exactly, due to the fact we don't know the individual song lengths (other than the shortest and longest songs), we do know 100% that the album length is somewhere between 22 minutes and 66 minutes.
In other words, 22 < x < 66 where x is the album length in minutes.
Of the four answer choices, 44 is the only one that fits, i.e. 22 < 44 < 66.
So I would say 44 minutes is a reasonable estimate. Or better yet, we can rule out 4 minutes, 88 minutes and 10 minutes as they don't fit in the interval 22 < x < 66.
We can calculate the volume V of a rectangular prism using V = lwh, where l is the length, w is the width, and h is the height of the
prism. Suppose that a prism has a volume of 200 cm and l = 2w.
a. Select all of the equations that rewrite the volume formula by making substitutions for V and l.
200 = 2w²h
200 = 4wh
V = 22
2w xwxh = 200
Answer:
Step-by-step explanation:
200=2w²h
The equations are -
200 = 2[tex]w^{2}[/tex]h
2w x w x h = 200
We have a prism and the formula to calculate its volume is given.
We have to select all of the equations that rewrite the volume formula by making substitutions for V = 200 cubic centimeter and L = 2w.
What is Prism ?A Prism is a three-dimensional shape, which consists of two identical polygons, which do not lie in the same axis.
According to the question, we have -
Volume of Prism = 200 cubic centimeter
L = 2w
The formula to calculate the volume of prism equals to -
V = Lwh
Substituting values, we get -
200 = 2[tex]w^{2}[/tex]h
or
2w x w x h = 200
Hence, the equations are -
200 = 2[tex]w^{2}[/tex]h
2w x w x h = 200
