Answer:
$861.09
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.
<em>A = total
</em>
<em>P = principal amount
</em>
<em>r = interest rate (decimal)
</em>
<em>t = time (years)
</em>
<em />
First, change 3.25% into its decimal form:
3.25% -> 
-> 0.0325
Next for <em>t, </em>we can use 4.25 since 4 years and 3 months is 4.25 in its decimal form. Now lets plug in the values:
Your answer is $861.09
Point A would be zero; Point B, the end of the 1/2-hour time interval, would be 1/2 (representing 1/2 hour). Then Amy needs to subdivide the interval A to B into three equal time intervals and to determine the length of each of these subintervals.
I would begin with 1/2 and divide that by 3:
1
--
2
====
3
--
1
Inverting the fraction in the denom. and multiplying, we get
1 1 1
-- * ---- = -----
2 3 6
So Amy will spend 1/6 th of an hour, or 10 minutes, on each chore.
Note that 3 times 1/6 comes out to 1/2 (hour), which is were we started.
Answer:
1/4n-2=10
Step-by-step explanation:
The weight of the boat translates to a volume of water displaced. When this volume of displaced water is less than the volume of the hull, the boat will float.
(weight(boat) x density(water)) / Total volume of the hull = percentage of hull submerged, i.e waterline
