A city has a population of 230,000 people. Suppose that each year the population grows by 9%. What will the population be after

zloy xaker [14]

<u>Answer:</u>

Step-by-step explanation:

If it grows by 9% each year, you can simply do the current population times 109%. Because its an additional 9%.

230,000*109% = 250,700

After the first year, there is a population of 250,700 people.

250,700*109% = 273,263

After the second year, there is a population of 273,263 people.

273,263*109% = 297,856.67

After the third year, there is a population of 297,856.67 people.

297,856.67*109% = 324,663.77

After the fourth year, there is a population of 324,663.77 people.

324,663.77*109% = 353,883.509

After the fifth year, there is a population of 353,883.509 people.

353,883.509*109% = 385,733.025

After the sixth year, there is a population of 385,733.025 people

Round it up to 385,733 people.

Answer:

the second one

Step-by-step explanation:

Hello There!

The area of a triangle can be found using this formula

$A = \frac{1}{2} (a+b)h$

where a and b = bases and h = height

The trapezoid shown has the following dimensions

top base = 9cm

bottom base = 14 cm

height = 12 cm

slant height = 13 cm

using this information, we plug in the values into the formula

So $A = \frac{1}{2} (9+14)12$

the equation we created matches the 2nd equation therefore the second one is your answer

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

The ratio of boys and girls =3:5

Let

Number of boys=3x

Number of girls =5x

According to the question Numbers of girls=130

${:}\longrightarrow$ $\sf 5x=130$

Now interchange both sides and get x

${:}\longrightarrow$ $\sf x={\dfrac {130}{5}}$

${:}\longrightarrow$ $\sf x=26$

The number of boys=3x

=3×26=78

$\therefore$ Number of boys is 78.
