Answer:

Step-by-step explanation:

This is really a sloppy diagram. You have to know if the base of the triangle is 5 or 10.

It is 5. So the area of 1 of the triangles is 1/2 * b * h

b = 5

h = 8.7

Area = 1/2 * 8.7 * 5 = 21.75

There are 4 such triangles. The total area = 4 * 21.75 = 87 sqr in

10 pancakes produces 8 inches in diameter. 
The area of 1 pancake is 
Area = pi * r^2
Area = pi * 4^2
Area = 50.27 in^2
Then multiply it by 10
Total area = 502.65 in^2

A smaller pancake
Area = pi * r^2
Area = pi * 2^2
<span>Area = 12.56 in^2

Divide 502.65 by 12.56
= 502.65 / 12.65
= 39.74

So there are 39 pancakes.

What initial investment must be made to accumulate $60000 in 17 years if the money is invested in a mutual fund that pays 12% an
mars1129 [50]

$7881.18

Step-by-step explanation:

   Let the initial Investment be P_{0}. The Interest is compounded on a monthly basis at 12% annual interest rate. After 17 years, the Investment amounts to $60,000.

   As the annual interest rate is 12%, the monthly interest rate is 1%.

Since this is a compound interest problem, the total amount can be modeled as follows: P(t)=P_{0}(1+\frac{i}{100})^{t}

Here i is the interest rate, i.e 1, and t is the number of time periods, i.e 17\textrm{ years x }12\frac{\textrm{months}}{\textrm{year}}= 204\textrm{ months}

60,000=P_{0}\textrm{ x }(\frac{101}{100})^{204}

P_{0}=7881.18

∴ Initial Investment = $7881.18
