Answer:

12

Step-by-step explanation:

I always look at ratios as fractions.

since 3/4 ratio and there are 9 boys and 3*36=9.

that means 4*3=12.

we can check by simplifing 9/12 equals 3/4.

1600 dollars is placed in an account with an annual interest rate of 5.25%. How much will be in the account after 25 years, to t
Andru [333]

Step-by-step explanation:

Exponential Functions:

y=ab^x

y=ab

x

a=\text{starting value = }1600

a=starting value = 1600

r=\text{rate = }5.25\% = 0.0525

r=rate = 5.25%=0.0525

\text{Exponential Growth:}

Exponential Growth:

b=1+r=1+0.0525=1.0525

b=1+r=1+0.0525=1.0525

\text{Write Exponential Function:}

Write Exponential Function:

y=1600(1.0525)^x

y=1600(1.0525)

x

Put it all together

\text{Plug in time for x:}

Plug in time for x:

y=1600(1.0525)^{25}

y=1600(1.0525)

25

y= 5750.0628984

y=5750.0628984

Evaluate

y\approx 5750.06

y≈5750.06

How do I do #12? <br><br> Please show all work. <br><br> Please help!
hammer [34]

You have the ratio set up correctly:

2x+2/12 = x+3/21

Now cross multiply:

2x+2 * 12 = x+3 * 21

Simplify:

24x + 24 = 21x + 63

Subtract 24 from each side:

24x = 21x + 39

Subtract 21x from each side:

3x = 39

Divide both sides by 3:

x = 39/3

x = 13
