Answer:
D
Step-by-step explanation:
Firstly let's see definition of Rational numbers ,
<u>Rational</u><u> numbers</u><u> </u><u>:</u><u>-</u><u> </u>
- The number in the form of p/ q where p and q are integers and q is not equal to zero is called a Rational number .
From the options , look at option D ,its
→ √400
→ √{20²}
→ 20
<h3>
Hence option D is correct.</h3>
Answer:
Least number is 60.
Step-by-step explanation:
Let the number of CDs has Jo be represented by x + 10. Where x = 0, 1, 2, 3....
Then, since Ken has twice as many CDs as Jo, the number of CDs that Ken has can be expressed as;
2(x + 10) = 2x + 20
Maisie has three times as many CDs as Ken, then the number of CDs that Maisie has can be expressed as;
3(2x + 20) = 6x + 60
Thus to determine the least number of CDs that Maisie can have, let x = 0.
3(2x + 20) = 6x + 60
= 6(0) + 60
= 60
Therefore, the least number of CDs that Maisie can have is 60.

Answer:
91
Step-by-step explanation:
we will call Allen : A
we will call MIller: M
we will call James: J
The problem tells us we have three answers we need to find and it only gives us one of those answers. We can use that to find the other needed answers. We will start with answering the first one.
A = 44
We know from the given A = 44 so miller is half the weight we divide by 2.
A/2 = M
44/2 = 22 so we know that M is = to 22
then the question tells us james is three more than miller. we know from solving miller is 22.
M + 3 = J
22+3 = J
J=25
then the final question asks to add all of them together
A + M + J = Total weight
44 + 22 + 25 = Total Weight
91 = Total Weight
