Your sum is 4 times 10, or 40. We want to end up with 40. Subtract 8 because you added 8 before to work backwards. You get 32. Divide by 16 because the opposite of multiplication is division. You would get 2.

Nap ate 2/5 of the pizza Rowan ate 2/3 of the pizza that was left how much of the pizza did Rowan eat
kicyunya [14]

Answer:

Rowan ate \frac{2}{5} of the pizza

Step-by-step explanation:

Nap ate 2/5 of the pizza Rowan ate 2/3 of the pizza that was left how much of the pizza did Rowan eat?

Nap: \frac{2}{5} can be rewritten as \frac{6}{15}

Rowan: \frac{2}{3} can be rewritten as \frac{10}{15}

After Nap ate 2/5 of the pizza, there is 3/5 pizza left.

\frac{3}{5} can be rewritten as \frac{9}{15}

 

\frac{9}{15}*\frac{10}{15} = \frac{2}{5}

\frac{9}{15}*\frac{10}{15}=\frac{3}{5}*\frac{2}{3}=\frac{1}{5}*\frac{2}{1} =\frac{2}{5}

Rowan ate \frac{2}{5} of the pizza

Hope this helps!

You deposit 3100 in an account with an annual interest of 3.4% for 20 years
tamaranim1 [39]

Answer:

The amount in 20 years is $6,050.24

Step-by-step explanation:

Given the following information:

Principal (Present Value, or PV)= $3,100

Interest rate ( <em>r </em>)= 3.4% or 0.034

Number of compounding period (<em>n </em>)= 1 (annually)

Number of years ( <em>t </em>)= 20

We can use the Future Value formula to find out the value of $3,100 in 20 years:

FV = PV(1 + \frac{r}{n})^{nt}

FV = 3100(1 + \frac{0.034}{1})^{1*20}

FV = 3100(1.034)^{20}

FV = 3100(1.95169)

FV = $6,050.24

Therefore, the future value of the amount deposited is $6,050.24
