Step-by-step explanation:
The lengths of the two longer legs are both
The lengths of the two shorter legs are both
So
The given ratio of powder to water is 3:2 based on weight for Kool-aide. It is also given that 120g of flavored powder is needed for a certain amount of Kool-aide.
Let us assume that the amount of water (by weight) required to maintain the given ratio of 3:2 be represented by the letter . Thus, from the given information we can conclude that:
Cross-multiplying we get:
grams.
Thus, the amount of water in grams in that Kool-aide is 80 grams.
For each situation, we have that:
11) Using compound interest, it is found that she needs to invest $9,781.11 now.
12) Using the future value formula, it is found that you will have $728,753 after 48 years.
<h3>What is compound interest?</h3>The amount of money earned, in compound interest, after t years, is given by:
In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
For this problem, the parameters are given as follows:
A(t) = 15000, t = 4, r = 0.055, n = 2.
Hence we solve for P to find the amount that needs to be invested.
P = $9,718.11.
She needs to invest $9,781.11 now.
<h3>What is the future value formula?</h3>It is given by:
In which:
- P is the payment.
- n is the number of payments.
- r is the interest rate.
For item 12, the parameters are given as follows:
P = 150, r = 0.07/12 = 0.005833, n = 48 x 12 = 576.
Hence the amount will be given by:
V(n) = $728,753.
You will have $728,753 after 48 years.
