Answer:
The balance in the account after 20 years will be $11280.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
.
In this problem
We want to find T, when
The first step is find the earnings due to interest. So
Adding to the principal to find the balance
The balance in the account after 20 years will be $11280.
Answer: option D is the correct answer.
Step-by-step explanation:
Let m represent the total number of minutes that the phone is used in a month.
Let C represent the amount of the bill for using m minutes.
His monthly bill will be $32.99 each month which includes 100 minutes of use. Additional minutes will cost $0.19 per minute. It means that the cost of additional minutes is
0.19(m - 100). Therefore, the linear model representing the amount of the bill would be
C = 0.19(m - 100) + 32.99
Answer:
Answer:
Step-by-step explanation:
1) One solution is to write, as our exponent:
2) Because this is special case of the Exponents Law, valid for every base ≠ 0.
3) Hence, including an exponent the numbers 6, 2 whose value is eight.
Therefore our expression is true
Step-by-step explanation:
Answer:
D. is the correct answer.
Step-by-step explanation:
The given situation can be represented as a figure attached in answer area.
B is the base of tree.
C is the base of wires.
A and D are the end of 2 wires supporting the tree.
Here, we need to find the Height of the tree which is represented the by side AB.
and we are given that bases of wires and tree base are at a distance 4 ft.
i.e. side BC = 4 ft
If we look at the , we are given the base BC and the , and the perpendicular is to be find out.
We can use trigonometric identity:
Hence, D. is the correct answer.
Step-by-step explanation:
A can is a cylinder.
Volume of a can = Volume of Cylinder
Given Radius = 3.2 inches and height = 15 inches,
Volume of one olive oil can =
Volume of 5 olive oil cans = 5 x volume of one olive can
I will just leave the answer in terms of pi as I'm not sure if you need to round off your answers.
