A sum of money is invested at 12% compounded quarterly. About how long will it take for the amount of money to double?

kompoz [17]

Answer:

5.9 years

Step-by-step explanation:

We believe a better representation of the compound interest formula is ...

$V(t)=P(1+\dfrac{r}{n})^{nt}$

We want to find the value of t for P=1 and V(t)=2. We are told n=4, so the formula becomes ...

$2=(1+\dfrac{.12}{4})^{4t}\\\\\log{(2)}=4t\log{(1.03)}\quad\text{take logs}\\\\t=\dfrac{\log{2}}{4\log{1.03}}\approx\boxed{5.9\quad\text{years}}$

Which fraction is larger 7/16 or 51/100?

zaharov [31]

51/100 would be larger
From the first look, I already know half of 100 is fifty and 51 is greater than that
So when I looked at 7/16, I was looking for something greater than half, but 7 is greater than half of 16.
51/100 is your answer

Which answer choice shows 4 + 0.3 + 0.09 written in standard form?

puteri [66]

Solution:

A few changes were made:

4 as 4.00.
0.3 as 0.30

New equation:

4 + 0.3 + 0.09 = 4.00 + 0.30 + 0.09

Solving the equation:

4.00 + 0.30 + 0.09
=> 4.39 (Refer to image for work)
