Which expression is a perfect cube

Mathematics
1 answer:
mamaluj [8]2 years ago
6 0

Answer: some perfect cubes are

8 (2^3)

27 (3^3)

64 (4^3)

there are many perfect cubes

maybe there is more to this question?

Step-by-step explanation:

A perfect cube of a number is a number that is equal to the number, multiplied by itself, three times. If x is a perfect cube of y, then x = y3. Therefore, if we take the cube root of a perfect cube, we get a natural number and not a fraction. Hence, 3√x = y. For example, 8 is a perfect cube because 3√8 = 2.

Express 0,mnmnmn.... = 0 ,mn, where m and n are distinct integers,in the form p/q where p and q are integers
Rama09 [41]

The required fraction in the form of a/b is 2343/100

<h3>Fractions</h3>

Fractions are written as a ratio of 2 integers

Since the question is incomplete, we can e<u>xpress the decimal 23.43 as a fraction in the form p/q</u>

Given the decimal number 23.43

  • 23.43 = 2343/100

To get this, you will replace the decimal point by 1 and then add zeros depending on the number of decimal numbers that we have.

a sheep breeding farm counted a total of 40 sheep on their grounds after one year the number of sheep doubled then in the next y
SpyIntel [72]
Answer:
graph (b)

Explanation:
The farm started with 40 sheep and the number doubled each year.
So, the equation modeling this situation would be:
N(x) = 40*(2)^2
By getting the equation, we can notice that we already excluded the third and fourth choices as they have the wrong equations.

Now, we will need to select the right graph which is either graph a or graph b.
To do this, we will get the value of N(x) for different values of x as follows:
At x = 0: N(0) = 40*(2)^0 = 40
At x = 1: N(1) = 40*(2)^1 = 80
At x = 1: N(2) = 40*(2)^2 = 160

Now, taking a look at graph a, we will find that:
N(1) = 120
N(2) = 360
These numbers are not the same as the numbers we calculated, therefore, this graph is wrong

Taking a look at graph b, we will find that:
N(1) = 80
N(2) = 160
These numbers are exactly the same as the ones calculated, therefore, this graph is the correct one.

Hope this helps :)

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.

  To find the percentage always multiply whatever decimal number you have by 100% <span>
1) 5 + 8 + 12 = 25 (total number in bag) 
5/25 x 100% (because you're trying to find probability of red) 
= 20% 

2) 5 + 8 = 13 (# of red AND blue) 
13/25 x 100% (divide out of the total) 
=52% 

3) 5/25 = 0.2 x 12/25 = 0.48 (find probability of drawing red and green) 
0.2 x 0.48 x 100% 
= 9.6% 

4) 10 + 12 + 28 = 50 (to find total number of trials) 
28/50 x 100% 
= 56% 

5) 5 x 7 (number of sections on first spinner multiply by # of sections on second spinner) 
= 35</span><span>Its B 20%
