<span>The answer is:
not a dilation because the points of the image are not moved toward the center of dilation proportionally</span>
The r% of a quantity x is computed by dividing x in 100 parts, and considering r of such parts. So, the r% of the male is

and similarly, the r% of female is

The number of males decreased by this quantity, so now it is

and the number of female increased by this quantity, so now it is

we know that these two new counts are the same number, so we can build and solve the equality

Subtract 20 and add 0.3r from both sides:

Divide both sides by 0.5 to solve for r:

Let's check the answer
The 20% of 30 is
, while the 20% of 20 is 4. So, we are stating that
which is true because both expressions evaluate to 24.
Answer:
1 out of 3 times more likley but
Step-by-step explanation:
Answer:
648
Step-by-step explanation:
Write 162% as 162
/100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
162
/100 of 400 = 162
/100
× 400
Therefore, the answer is 648
If you are using a calculator, simply enter 162÷100×400 which will give you 648 as the answer
