the population of a town is 1,03.500 if 56%of the population is male find the number of females in the town
bija089 [108]
The population you gave isn't formatted correctly so I'll solve the problem assuming you mean 103,500.

First we find the number of males from the percentage given:

0.56 * 103500 = 57960 males

Subtract the number of males from the total population to get the number of females:

103500 - 57960 = 45540 females

You could solve the problem by finding the percentage of females first. Since there are 56% males, that means there are 100-56 = 44% females.

0.44 * 103500 = 45540

The answer is 45540.

PLSSS ANSWER, 35 pointss

Answer:

1.

(y - 5)(x + y)

2.

{(x - y)}(x - y   + a)

3.

(b - 3)(5b - 17)

Step-by-step explanation:

1. The given polynomial is

x(y - 5) - y(5 - y)

We need to factor the second part to get:

x(y - 5)  +  y(y - 5)

We factor y-5 to obtain:

(y - 5)(x + y)

2. We have

{(x - y)}^{2}  - a(y - x)

We again factor -1 from the second part to get:

{(x - y)}^{2} +  a(x- y)

We now factor x-y to get:

{(x - y)}^{2}   + a(x- y)

{(x - y)}(x - y   + a)

3. We have

2(3 - b) + 5 {(b - 3})^{2}

We factor negative 1 from the first part to get

- 2(b - 3) + 5 {(b - 3})^{2}

We now factor b-3 to get:

(b - 3)( - 2 + 5(b - 3))

We now simplify to get:

(b - 3)( - 2 + 5b - 15) = (b - 3)(5b - 17)
