Answer:

In year 2026 population of both the states will be same.

Step-by-step explanation:

It has been given in the question that the population y of State A in year x will be represented by the equation

-3x + y = 11,400

⇒ y = 11,400 + 3x --------(1)

Similarly, equation that represents the population for State B is

-138x + y = 8,000

⇒ y = 138x + 8,000 -------(2)

If population y for both the states are equal then

3x + 11,400 = 138x + 8,000

11400 - 8000 = 138x - 3x

135x = 3400

x=\frac{3400}{135}

x = 25.19 [After 25 years ]

Since  x = 0 represents the population of the states in year 2000

therefore, population y will be same in both the states in year (2000 + 26)

= 2026

Pearl uses 9.8 pints of blue paint and white paint to paint her bedroom walls. 2 5 of this amount is blue paint, and the rest is
Ratling [72]

Answer:

She use <u>5.88 pints</u> of white paint.

Step-by-step explanation:

Given:

Pearl uses 9.8 pints of blue paint and white paint to paint her bedroom walls. \frac{2}{5} of this amount is blue paint, and the rest is white paint.

Now, to find the pints of white paint she use.

Pearl uses total pint of paint = 9.8 pints.

The amount of blue paint

= \frac{2}{5}\ of\ 9.8\ pints.

= \frac{2}{5} \times 9.8

= \frac{19.6}{5}

= 3.92\ pints.

Thus, the amount of blue paint = 3.92 pints.

Now, to get the white paint we subtract the amount of blue paint from  the total pint of paint:

9.8-3.92\\\\=5.88\ pints.

Therefore, she use 5.88 pints of white paint.

The area of circle mowed is 6644.24 square feet.

Step-by-step explanation:

Given,

Radius of circle = 46 feet

Area of circle is given by πr².

Area of circle = \pi r^2

Area of circle = 3.14*(46)^2

Area of circle = 3.14 * 2116

Area of circle = 6644.24 square feet

The area of circle mowed is 6644.24 square feet.

In the lab, Keith has two solutions that contain alcohol and is mixing them with each other. He uses twice as much Solution A as
egoroff_w [7]

Answer:

Quantity of solution B required is 300 ml

Step-by-step explanation:

Let "a" be quantity of solution A required

Let "b" be quantity of solution B required

We are given Solution A is 19% alcohol and Solution B is 14% alcohol and that the resulting mixture has 156 milliliters of pure alcohol

Thus;

0.19a + 0.14b = 156 - - - (eq 1)

Also, He uses twice as much Solution A as Solution B.

Thus;

a = 2b

Putting 2b for a in eq 1 gives;

0.19(2b) + 0.14b = 156

0.38b + 0.14b = 156

0.52b = 156

b = 156/0.52

b = 300 ml

Quantity of solution B required is 300 ml
