Answer:
(a) Amount owed after 2 years is $ 1081.54
(b) The shark's vig is $ 1031.54
Step-by-step explanation:
(a)
The amount on a principal, <em>P</em>, after a period, <em>T</em>, at a compound interest, <em>R</em>, is given by
From the question,
<em>P</em> = $ 50
<em>R</em> = 3% per week
<em>T</em> = number of weeks in 2 years = 2 × 52 = 104 (Assuming 52 weeks for each year)
(b)
The shark's vig = $ 1081.54 - $ 50 = $ 1031.54
Answer:
<em>15 times and more. After she pours the 15th container, in the middle of the next one, the work will be done.</em>
Step-by-step explanation:
<u>Length, Area, and Volume Scale Factors</u>
If two similar shapes have a length scale factor of a:b, then the scale factor of their areas (or surface lateral areas) is and the scale factor of their volumes is
.
We are given the scale factor of the surface areas of two similar containers A and B as 4:25.
The length scale factor is
The volume scale factor is: = 125:8 = 15.625
Warda needs to fill with oil and pour into container B 15.625 times to get container B full of oil.
Thus, after she pours the 15th container, in the middle of the next one, the work will be done
