Answer:
The amount the $20.000 will be worth in 17 years at compound interest is $65068.443
Step-by-step explanation:
Here we have the Principal, P = $20,000.00
The annual interest rate, r = 7% = 0.07
Time , t = 17 years
Number of compounding period per year, m = quarterly = 4
The compound interest can be found from the following formula;
Therefore, by plugging the values of the equation parameters, we have;
Therefore, the amount the $20.000 will be worth in 17 years at compound interest = $65068.443.
Answer:
<em>The elephants' moat should be 3.2 meters deep.</em>
Step-by-step explanation:
Suppose, the depth of the elephants' moat is 
meter.
Width of the lions' moat is 5 meter and width of the elephants' moat is 4 meter.
Given that, the lion’s moat is 4 meter deep.
So, <u>according to the ratio of width and depth</u>, the equation will be.......
Thus, the elephants' moat should be 3.2 meters deep.
Alright so if I do remember my math correctly, this is how it goes:
- y = -x^2 + x + 3
- x = -b/2a
- x = -1/2(-1)
- x = -1/-2, which = (1/2)
Not quite sure if this was correct, but if it was, hope this helps and you're welcome! :)
Answer:
C
Step-by-step explanation:
If 9 members paid on the first day, this means they did not pay on the third day
The remaining people (everyone but the 9) paid on the third day
Therefore we must subtract to find out how many members paid on the third day
22 - 9 = 13
Each of the 13 members paid $12.80 which means we must multiply
13 × 12.80 = 166.40
In total, the grocery store collected $166.40 on the third day of the month
