Answer:
75cm is the measurment
Step-by-step explanation:
It would have had to have been the lenght of the gem because 75cm or 75 centimeters is a measurment not the mass of something. The mass is the amount of matter in an object.
Answer:
2 pieces
Step-by-step explanation:
3/4 = 6/8 (multiply by 2/2)
![\frac{6}{8}/\frac{3}{8} =\frac{6}{8} * \frac{8}{3} = \frac{6}{3} =2pieces](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B8%7D%2F%5Cfrac%7B3%7D%7B8%7D%20%3D%5Cfrac%7B6%7D%7B8%7D%20%20%2A%20%5Cfrac%7B8%7D%7B3%7D%20%3D%20%5Cfrac%7B6%7D%7B3%7D%20%3D2pieces)

<u><em>If the question was similar to the one given below </em></u>
A researcher plans to identify each participant in a certain medical experiment with a code consisting of either a single letter or a pair of distinct letters written in alphabetical order. What is the least number of letters that can be used if there are 12 participants, and each participant is to receive a different code?
<em><u>The answer would be as follows</u></em>
If we use 3 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
4C2= 6 ways to use these letters and the comma
If we use 4 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
5C2= 10 ways to use these letters and the comma
If we use 5 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
6C2= 15 ways to use these letters and the comma
We need the least number of the alphabets to assign codes to 12 participants.
So the least number of alphabets is 5 because it can give codes to at least to 12 people .
Pair of alphabets + distinct letter ≥ 12
5 + 1 ≥ 12
6c2 ≥ 12
15 ≥ 12
Answer:
The volume of the water in the pool is 1,017 cubic feet
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
![V=\pi r^{2} h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7D%20h)
we have
----> the radius is half the diameter
Remember that
![1\ ft=12\ in](https://tex.z-dn.net/?f=1%5C%20ft%3D12%5C%20in)
so
![6\ in=6/12=0.5\ ft](https://tex.z-dn.net/?f=6%5C%20in%3D6%2F12%3D0.5%5C%20ft)
To find out the height of the water, subtract 0.5 feet from the height of the swimming pool
![h=4.5-0.5=4\ ft](https://tex.z-dn.net/?f=h%3D4.5-0.5%3D4%5C%20ft)
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
Find the volume of the water
![V=(3.14)(9^{2})(4)](https://tex.z-dn.net/?f=V%3D%283.14%29%289%5E%7B2%7D%29%284%29)
![V=1,017\ ft^3](https://tex.z-dn.net/?f=V%3D1%2C017%5C%20ft%5E3)
