Commemorative coins come in packs of 15,while coin holders come in packs of 25. What are the least numbers of packs you should buy in order to have the same numbers 9f coins and coins holders

Answer:

5 packs of commemorative coins and 3 packs of coin holders.

Step-by-step explanation:

We have been given that commemorative coins come in packs of 15,while coin holders come in packs of 25.

To find the least number of packs, we need to find LCM of 15 and 25.

Multiples of 15: 15, 30, 45, 60 ,75, 90,..

Multiples of 25: 25, 50, 75, 100,...

We can see that least common multiple of 15 and 25 is 75.

\text{Packs of commemorative coins}=\frac{75}{15}=5

\text{Packs of coin holders}=\frac{75}{25}=3

Therefore, you should buy 5 packs of commemorative coins and 3 packs of coin holders.

What does a mu mean in physics


'mu' is a letter in the Greek alphabet.  It looks like this:  μ
If you need labels for quantities or variables in math or science,
you can use any letter from any alphabet you like ... just be sure
to explain what the symbol stands for somewhere on the page
where the equation or formula is.

I've seen 'mu' used to stand for 'micro-' when writing units.
For example:

" μ-meter " ... one millionth of a meter

" μ-farad " ... one millionth of a farad

" μ-second " ... one millionth of a second

Explain how language is much more than just a means of communication

Language is much more than communication because it also shows culture. How did they originally start it? Why is it different than ours? There are many reasons, but we don't normally look into it. Language can be communication, but it's also a way of life. Without it, we wouldn't be able to understand each other. Language is a key part of our lives to express ourselves whilst others can hear what we have to say. Language is far more than communication, it's something that everyone in the world has.        Hope this helps. Copy it if you wish :)

QUESTION POSTED AT 05/12/2019 - 11:11 PM

My algebra math book has this math problem ---> 4a - 3b = 21. i am supposed to figure out if it is true or false. but the thing is, i do not know how to do this so that i can find out if it is true or not. PLEASE HELP!!!!!


The value of (4a - 3b) depends on what 'a' and 'b' are.

There are many combinations of 'a' and 'b' that make
(4a - 3b) equal to 21, and a whole bunch of others
that don't.

The equation in your question is not true OR false until you know
what 'a' and 'b' are.  I suspect that right next to this problem in your
math book, it gives you some values for 'a' and 'b'.

Here are a few examples of how to do it:

1).  I tell you that  a=2  and  b=1.
You take those numbers, and write them in place
of 'a' and 'b' in the left side of the equation:

                   4a - 3b

                  4(2) - 3(1)

                    8   -   3  =  5

If  a=2  and  b=1, then the left side of the equation is  5, not 21,
and the equation is false. 

================================

2).  I tell you that  a=5  and  b=4.
You take those numbers, and write them in place
of 'a' and 'b' in the left side of the equation:

                       4a - 3b

                       4(5) - 3(4)

                         20 -  12  =  8

If  a=5  and  b=4, then the left side of the equation is  8, not 21,
and the equation is false. 

=================================

3).  I tell you that  a=6  and  b=1.
You take those numbers, and write them in place
of 'a' and 'b' in the left side of the equation:

                   4a - 3b

                 4(6) - 3(1)

                   24  - 3  =  21

If  a=6  and  b=1, then the left side of the equation is  21,
and the equation is TRUE.

This is not the only possible pair of numbers for 'a' and 'b'
that make the equation true.  There are tons of possibilities.
Look around the question in your book and see if it gives you
values for 'a' and 'b' to test in the equation.

What is the answer to x+36=4x

X + 36 = 4x

First, subtract x from both sides. / Your problem should look like: 36 = 4x - x
Second, simplify 4x - x to get 3x. / Your problem should look like: 36 = 3x
Third, divide both sides by 3. / Your problem should look like:  \frac{36}{3} = x
Fourth, simplify  \frac{36}{3} to get 12. / Your problem should look like: 12 = x
Fifth, switch the problem around (switch sides). / Your problem should look like: x = 12

Answer: x = 12

An athelete swims from northend to southend of a 50.0m pool in 20.0s and makes the return trip to the starting position in 22.0s a) What is the average velocity for the first half of the swim? b) what is tje average velocity for the second half of the swim? c) what is the average velocity for the roundtrip?


Average velocity =

    (distance between start-point and end-point) / (time from start to end)
in the direction of
    (direction from the start-point to the end-point) .

a).  The average velocity for the first half is

                             (50m)/(20sec) = 2.5 m/s south.

b).  The average velocity for the second half is 

                            (50m)/(22sec) = 2.273 m/s north

c).  Average velocity for the round trip is zero, because
the start-point and end-point are the same point.

However ...

Average SPEED = (total distance covered) / (time to cover the distance)

Average SPEED for the round trip is 

                 (100 m) / (42 sec) = 2.381 m/s  (rounded)

If joanne can read 18 pages in 30 mins how long will it take her to read 63 pages? Explain how yu got your answer

Every 18 pages takes 30 minutes to read. Since she has to read 63 pages  more pages, it would take more than 90 minutes(18+18+18 =54 pages) but less than 120 minutes (18+18+18+18=72) pages. 9 more pages need to be read and that would be dome in half the time of 18 pages or 15 minutes. 90 minutes plus 15 minutes= 105 minutes or 1 hour 45 minutes.

The waiting time to ride a roller coaster is 20 minutes when 150 people are in line. how long is the waiting time when 240 people are in line?

If you have to wait 20 minutes when 150 people are in line, you will have to wait 10 minutes for 75 people, and 2 minutes for 15 people. I divided both numbers by two to finding out the simplest form, but it didn't help. I went back and divided by numbers by 10 to get 2 minutes for 15 people.  Since you would wait 4 minutes for 30 people. You would also wait 20 minutes for 150 people, and 32 minutes for 240 people.
