The reason why people sometimes assume that the calculation 9 + 10 = 21 is as explained below.
<h3>How to calculate in number bases?</h3>
We want to find out the reason why people say that; 9 + 10 = 21
Now, the way you have explained it is one way to look at it by utilizing number bases to play around with the figures to arrive at 21.
However, another way is to use algebra trick pattern which is;
9 can be expressed as 3 * 3
Also, 10 can be expressed as 5 * 2. Thus, we now have;
(3 * 3) + (5 * 2)
The applying properties of algebra to cross multiply gives;
(3 * 2) + (5 * 3)
= 6 + 15
= 21
Now, though your explanation arrived at 21 and mine also 21, but those are not correct mathematical methods as 9 + 10 must be equal to 19 and not 21.

Answer:
Volume of the given oblique cylinder = 36π units³
Step-by-step explanation:
Volume of the oblique cylinder = πr²h
Here, 'r' = Radius of the circular base
'h' = Height of the cylinder
For the given oblique cylinder,
Radius of the circular base = 3 units
Height of the cylinder = 4 units
Volume of the cylinder = π(3)²(4)
= 36π units³
Therefore, volume of the given oblique cylinder = 36π units³
2,000
10,000 divided by 5 = 2,000
Use easy numbers if you get confused on problems like these.
I'm going to use 12 instead of c.
Since you have 12 pieces of candy and 6 friends, each friend would get 2 pieces, because 12/6=2.
Now, substitute c for 12, and you get c/6.
Hope this helps!
Answer:
Cookie monster needs to steal at least 6 cookies more.
Step-by-step explanation:
Given:
Number of cookies already stole = 4
Total number of cookies he wants to steal 
We need to find how many cookie he needs to steal more.
Solution:
Let number of cookies he needs to steal more be 'x'.
Now we can say that;
Number of cookies already stole plus number of cookies he needs to steal more should be greater than or equal to Total number of cookies he wants to steal
framing in equation form we get;
Now using Subtraction property of Inequality we will subtract both side by 4 we get;
Hence Cookie monster needs to steal at least 6 cookies more.
