If your initial principal is $243 and your principal in 2 years is $1,359.19, how much interest did you earn?
Answer: $1,116.19
Step-by-step explanation:
If you invested $243 and this increased to $1,359.19 in two years, the difference between your investment and its current worth is the interest:
= Current principal - Initial principal
= 1,359.19 - 243
= $1,116.19

Why does the highest percent profit occur with the smallest annual interest rate?
Answer:
This is so because the higher the interest rate the lower the profit and the higher the total expenses and the percentage profit = (Profit/Expenses) × 100
Step-by-step explanation:
Question;
It is desired to find out the monthly percentage profit made to help decide the best loan option
Part A
Given that the monthly operating cost of the gym is 5,000 and the monthly sales is 7,500
Let 'I' represent the monthly interest paid on the loan, we have;
The percentage profit = Profit/(Total expenses) × 100
The total expenses = I + 5000
Profit = Sales - The total expenses
∴ Profit = 7,500 - (I + 5,000) = 2,500 - I
The percentage profit, P = (2,500 - I)/(5,000 + I) × 100
Therefore, as the interest rate becomes smaller, the numerator of the function for the percentage profit approaches its maximum value of 2,500 and the denominator approaches the minimum value of 5,000 and the percentage profit therefore, approaches the maximum value
Therefore;
The highest percentage profit occurs at the smallest interest rate.

You are constructing a 95% confidence interval using the information: n = 60, x-bar = 65.5, s = 2.5, and E = 0.70. What is the value in the middle of the interval?
Answer:
65.5
Step-by-step explanation:
Using the relation :
Xbar ± Margin of error
Margin of Error = Zcritical * s/√n
The Zcritical value at 95% = 1.96
Hence,
Margin of Error = 1.96 * 2.5/√60
Margin of Error = 1.96 * 0.3227486
Margin of Error = 0.6326
Lower boundary = 65.5 - 0.6326 = 64.867
Upper boundary = 65.5 + 0.6326 = 66.133
(64.867 + 66.133) / 2
The ratio of boys to girls is 2 to 3. If there are 90 students in the band, how many of them are boys?
Answer:
36
Step-by-step explanation:
We can make an algebric equation.
2x+3x=90
5x=90
x=18
Since we wanna find the boys, we multiply the boys ratio with our x value.
2x=2•18=36 boys

5/8 + 3/4 divided by -2/3 - 5/6
Answer:
11/12
Step-by-step explanation:
4x = 2(x-5)-2 can you solve please
Answer:
x = -6
Step-by-step explanation:
4x = 2(x-5)-2
2 * x = 2x
2*-5 = -10
4x = 2x - 10 -2
4x = 2x - 12
4x - 2x = 2x
2x = -12
-12/2 = -6
x = -6

F(x)=4x^2+3x+13
Find f(1)
Answer:
f(1) = 42
Step-by-step explanation:
Step 1: Switch all x out to 1 for f(1) which would look like this: f(1)=4(1)^2+3(1)+13
Step 2: You would then simplify it starting with 4(1)^2 which would equal 4 squared which equals 16.
Step 3: After simplifying you would have f(1)=16+3+13
Step 4: You then just add and get 42

Answer:
a. east
b. 60 feet per second
Step-by-step explanation:
did this a while ago.
a. -180 is east, 120 is east. the car is traveling east because it is moving positive. read the last sentence of the description.
b. to calculate velocity you do time times position. in this case position is 60 and time is 1 so 60*1 is 60. so it is 60 feet per second.

The solutions of the of the equation are,
⇒ x = 3.12
⇒ x = 0.21
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ (3x - 5)² = 19
Now,
We can simplify the expression for the solutions as;
⇒ (3x - 5)² = 19
Take square root both side,
⇒ √(3x - 5)² = √19
⇒ (3x - 5) = √19
Add 5 both side,
⇒ 3x - 5 + 5 = √19 + 5
⇒ 3x = √19 + 5
⇒ 3x = ± 4.36 + 5
⇒ 3x = 4.56 + 5
⇒ 3x = 9.36
Divide by 3;
⇒ x = 9.36 / 3
⇒ x = 3.12
And, 3x = - 4.56 + 5
3x = 0.64
x = 0.64/3
x = 0.21
Thus, The solutions of the of the equation are,
⇒ x = 3.12
⇒ x = 0.21
