Answer:

12 girls are in the classroom.

Step-by-step explanation:

We find out that the ratio is 3:4 based upon the question.

If there's 9 boys then the ratio is incomplete however you just need complete it based on the information given.

So, 3:4

      9:?

9 / 3 = 3

4 x 3 - 12 girls

Thus, there being 12 girls in the classroom.

<em>To check: </em>

<em>9:12; </em>

<em>9 / 3 = </em> <em>3</em>

<em>12 / = 4 </em>

<em>So the ratio still ends up being 3:4 therefore 9:12 is equivalent and correct!</em>

<em>Hope this helped! Have a great day or night wherever you are, stay safe!</em>

If the population of a country increases at a rate of 1.5% annually and its current population is 430,000, how many years will i
Sphinxa [80]

Answer:

That is 74 years.

Step-by-step explanation:

1.5% = 0.015.

The equation for the rate of growth is P = 430,000(1.015)^n where n is the number of years.

Triple the population  is 430,000 * 3 =  1,290,000, so:

1,290,000 = 430,000(1.015)^n

(1.015)^n = 1290,000 / 430,000 = 3

Taking logs of both sides:

n log 1.015 = log 3

n = log 3 / log 1.015  =  73.8 years

Solve with steps<br> 5^(x+3)=25^(x-2)
Taya2010 [7]

5^(x+3)=25^(x-2)

Apply the exponent rule ( 5 ^2 = 25, so remove the 5 and replace 25?with 2)


x + 3 = 2(x-2)

Simplify:

X + 3 = 2x -4

Add 4 to both sides:

X + 7 = 2x

Subtract x from both sides

X = 7


Answer: x = 7
