Pythagoras; a^2 + b^2 = c^2 So, (6.7)^2 + (5.5)^2 = 75.14 then square root to get, 8.668 (to 3 d.p) hope this helps!!
Answer:
Step-by-step explanation:
Any time you have compounding more than once a year (which is annually), unless we are talking about compounding continuously, you will use the formula
![A(t)=P(1+\frac{r}{n})^{(n)(t)}](https://tex.z-dn.net/?f=A%28t%29%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7B%28n%29%28t%29%7D)
Here's what we have:
The amount after a certain time that she has in the bank is 4672.12; that's A(t).
The interest rate in decimal form is .18; that's r.
The number of times the interest compounds is 12; that's n
and the time that the money is invested is 3.5 years; that's t.
Filling all that into the formula:
Simplifying it down a bit:
Raise 1.015 to the 42nd power to get
4672.12 = P(1.868847115) and divide to get P alone:
P = 2500.00
She invested $2500.00 initially.
Okay. So, Amber used 1/2 of the 4/5 bag for the art project. Let’s do 4/5 / 2. 4/5 * 1/2 is 4/10 or 2/5 in simplest form. Amber uses 2/5 of a pound of sand for her art project.
