Answer:

1. Reduction.

2. (0, 0)

3. 1/3

Step-by-step explanation:

1. This is a reduction becuase the image gets smaller.

2. The point of dilation is the origin because that is what they both share and it is where is shrinks with. Sorry if that sounded really weird it is how I like to think about it.

3. The scale factor is 1/3 because the size shrinks 3 times.

45% of the population of a city are men

leonid [27]

Answer:

$\boxed{\textsf{ The number of children is \textbf{24150}.}}$

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 ,

$\sf\implies Percentage_{(men)}= 45/% .\\\\\sf\implies Percentage_{(children)}= 15\% .$

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 ,

$\purple{\bigstar}\underline{\underline{\boldsymbol{ According\ to \ Question :- }}}$

$\sf\implies 40\% \ of \ x \ = \ 64,400 \\\\\sf\implies \dfrac{40x}{100}= 64,400 \\\\\sf\implies x =\dfrac{64,400\times 100}{40}\\\\\sf\implies \boxed{\pink{\sf x = 161,000 }}$

$\rule{200}2$

The percentage of children = 15% :-

$\sf\implies Number_{(children)}= 15\% \ of 161,000\\\\\sf\implies Number_{(children)}= \dfrac{15}{100}\times 161,000 \\\\\sf\implies \boxed{\pink{\frak {Number_{(children)}= 24150 }}}$

240,000 written as a whole number multiplied by a power of ten

IrinaK [193]

240,000 written as a whole number multiplied by a power of ten:

In the provided number 240,000 if we want to multiply this number by a power of ten then it would be like 240,000 raised to the power of 10
1. In which clearly stating that 240,000 shall multiply itself by 10 times in 240,000.
 2. Hence 240, 000^10 in numerical form 
3. The result is 6.340338097x10^53 
4. It seems like the product is a lot bigger and capsized itself to a smaller scientific reading but its still big in value because of the its current 53 power.

Hope this helps!
