Answer: Second equation should be x/10 = 12/16
Step-by-step explanation:
Everything is right except that x=12 and 10=16
Answer:
Step-by-step explanation:
Remark
If this compounds, it means that the interest of the second year has the interest of the first year added to the principle. So if you gain 50 dollars as interest in the first year and the base amount was 1000 dollars, the second year will be taken as 1050 and you will find the interest on that.
Formula
Your formula should be A = P(1 + r)^t
Givens
- A = ??
- P = 165,000
- r = 8% = 8/100 = 0.08
- t = 3 years
Solution
- A = 165000*(1 + 0.08)^3
- A = 165000*(1.08)^3
- A = 165000*1.259712
- A = $207852
Answer: A
<em><u>Problem 2</u></em>
Givens
- P = 5000
- i = 17% = 17/100 = 0.17
- t = 15 years
- A = ?
Formula
A = P (1 + r)*t This is not compounded
Solution
A = 5000*(1 + 0.17)*15
A = [5000*1.17]*15
A = 5850 * 15
A = $87750
Answer C
Answer:
We know that:
If T = area of the triangle
and R = area of the rectangle:
I T - RI < 4.
Now, we know that:
T = 8*6/2 = 8*3 = 24
R = 4*(x - 4) = 4*x - 16
Then replacing those values, we can write:
I24 - (4*x - 16)I < 4
I40 - 4*xI < 4
Now let's solve it:
First we aim for the first value that is not a solutions, this is when:
I40 - 4*xI = 4
we can write this as:
40 - 4*x = +-4
The first extreme is:
40 - 4*x = +4
x = (40 - 4)/4 = 9
The other extreme is:
40 - 4*x = -4
x = (40 + 4)/4 = 11.
Then the set of solutions is: S = (9, 11)
