Answer: The simplified form is 
Step-by-step explanation:
Since we have given that

As we know the "Exponential law":

So, it becomes

Now, at last it becomes,

Hence, the simplified form is 
Answer:

Step-by-step explanation:
Given that the 45% of the population of a city are men and 15% are children . The number of women is 64,400 . And we need to find the number of children . Here ,
So the percentage of women will be equal to [ 100 - ( 45 -15) ]% = [ 100 - 60 ]% = 40% .
So let us take the total number of people be x . So ,


<u>The </u><u>percentage</u><u> of</u><u> </u><u>children </u><u>=</u><u> </u><u>1</u><u>5</u><u>%</u><u> </u><u>:</u><u>-</u>

Answer:
39.5
Step-by-step explanation:
angle ABC=60=(5x+2)+(3x-2)
60=8x
x=7.5
Angle ABD=(5x+2),(sub x=7.5)
=(5*7.5+2)
=39.5
