68 is 17% of what number?
68 = 0.17 • X
x = [?]
Answer:
400
Step-by-step explanation:
Division cancels multiplication. Divide by 0.17 to isolate "x" on the right side of the equation.
68 = 0.17 * x
divide both sides by 0.17
400 = x
68 is 17 percentage of the number 400.
To find the number that 68 is 17% of, we can set up the equation:
17% of x = 68
To solve for x, we need to divide both sides of the equation by 17% (or 0.17 as a decimal):
x = 68 / 0.17
Evaluating the division:
x=400
Therefore, 68 is 17% of 400.

Amanda invests a sum of money in a retirement account with a fixed annual interest rate of 9 % compounded ontinuously . After 19 years , the balance reaches $38,956.06. What was the amount of the initial investment ?
Answer:
$7045.82
Step-by-step explanation:
The formula for the balance of an account earning interest at rate r compounded continuously for t years is ...
A = Pe^(rt)
We want to find P, given the other parameters in this formula.
__
38956.06 = P(e^(0.09×19)) = P(5.52896148)
P = 38956.06/5.52896148 ≈ 7045.82
The amount of the initial investment was about $7045.82.

What percentage of the tires can be expected to last more than 40,000 miles? Assume that Hankook Tires is considering a guarantee that will provide a discount on replacement tires if the original tires do not provide the guaranteed mileage.

Nancy Regan purchased a new diamond bracelet for $12,600. The state sales tax is 6% and the federal excise tax on the jewelry is 11%. What is the total purchase price of the bracelet? Round your answer to the nearest cent.
Using proportions, it is found that the total purchase price of the bracelet is of $10,769.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, we consider the two taxes, of 6% and 11%, hence the price suffers an increase of 17%, that is, the price is multiplied by 117% = 1.17 to reach $12,600, hence:
1.17p = 12600
p = 12600/1.17
p = 10769.
The total purchase price of the bracelet is of $10,769.

Please help!!!!!!!! Determine the function which corresponds to the given graph.
The rational function shown in the graph is:
[tex]y = \frac{x - 6}{x - 5}[/tex]
How to determine the function?
First, we can see that we have an asymptote at x = 5, so the denominator becomes equal to zero when x = 5.
Then the rational function is something like:
[tex]y = \frac{g(x)}{x - 5}[/tex]
We also can see that when x = 6, the function intercepts the x-axis, then we must have that:
g(6) = 0
So we can define:
g(x) = x - 6
So the rational function is:
[tex]y = \frac{x - 6}{x - 5}[/tex]

12) A job offers you $15 an hour. Your boss
states that a percentage of your check will
be taken out for taxes, and then $35 for
medical insurance and $4 for dental
insurance. If you worked 38 hours, and
your total paycheck (for the week) was
$462.60, what percentage is taken out for
taxes?
Answer:
12%Step-by-step explanation:
Total paycheck before taking out taxes and insurance :
38×15 = 570
Left Amount of money after applying taxes :
570 - 570×(p/100)
= 570×[1 - (p/100)]
= 570×[(100-p)/100]
= (570/100) × [100 - p]
= 5.7 × [100 - p]
After taking out the insurance amounts we can write this equation:
.,7 × [100 - p] - (35+4) = 462.6
⇔ 5.7 × [100 - p] - 39 = 462.6
⇔ 5,7 × [100 - p] = 462.6 + 39
⇔ 5,7 × [100 - p] = 501.6
⇔ 100 - p = 501.6/5.7
⇔ 100 - p = 88
⇔ p = 100 - 88
⇔ p = 12

Step-by-step explanation:
Finding the center.
The general formula for a circle is
(x - a)^2 + (y - b)^2 = r^2
The center is a and b. The center is marked as (6,5)
So the equation becomes
(x - 6)^2 + (y - 5)^2 = r^2
Finding the radius
The radius is found by calculating the distance between the center and any point on the circumference.
The point given on the circumference is (8,8)
x1 = 8
x2 = 6
y1 = 8
y2 = 5
r^2 = (8 - 6)^2 + (8 - 5)^2
r^2 = 2^2 + 3^2
r^2 = 4 + 9
r^2 = 13
Answer
(x - 6)^2 + (y - 5)^2 = 13

HELP ME PLEASE ! HOMEWORK DUE IN LESS THAN 2 HOURS! NO CLUE ON HOW TO DO THIS ! OFFERING 15 POINTS
Answer:
Edna had $510 more amount of money than Toby in the end.
Step-by-step explanation:
LET :-
Edna's amount of money - x
Fatimah's amount of money - y
Toby's amount of money - z
Now,
By the question,
x = 4y
y : (y + z) = 5 : 8
y - 30 = z + 30
Now,
y : (y + z) = 5 :8
or, y/(y + z) = 5/8
or, 8y = 5y + 5z
or, 3y = 5z
so, y = 5z/3
Now,
y - 30 = z + 30
or, 5z/3 - 30 = z + 30
or, (5z - 90)/3 = z + 30
or, 5z - 90 = 3z + 90
or, 5z - 3z = 90 + 90
or, 2z = 180
so, z = 90
Toby's amount of money - $90
Now,
y = 5z/3
or, y = 5 * 90/3
or, y = 5 * 30
so, y = 150
Fatimah's amount of money - $150
Again,
x = 4y
or, x = 4*150
or, x = 600
Edna's amount of money - $600
Now,
$600 - $90
= $510
Therefore,Edna had $510 more amount of money than Toby in the end.
Balloons By Sunset (BBS) is considering the purchase of two new hot air balloons so that it can expand its desert sunset tours. Various information about the proposed investment follows: (Future Value of $1, Present Value of $1, Future Value Annuity of $1, Present Value Annuity of $1.) (Use appropriate factor(s) from the tables provided.)
Initial investment (for two hot air balloons) $ 399,000
Useful life 9 years
Salvage value $ 48,000
Annual net income generated 30,324
BBS’s cost of capital 8 %
Assume straight line depreciation method is used.
Required:
Help BBS evaluate this project by calculating each of the following:
1. Accounting rate of return. (Round your answer to 2 decimal places.)
2. Payback period. (Round your answer to 2 decimal places.)
3. Net present value (NPV). (Do not round intermediate calculations. Negative amount should be indicated by a minus sign. Round the final answer to nearest whole dollar.)
4. Recalculate the NPV assuming BBS's cost of capital is 11 percent. (Do not round intermediate calculations. Negative amount should be indicated by a minus sign. Round the final answer to nearest whole dollar.)
I'm mostly confused on NPV
The accounting rate of return is 7.6%, the payback period is 5.755 years, the Net present value is $58,072, and the net present value(11%) is $3611.
What is NPV?The Net Present Value (NPV) is a corporate finance technique for analyzing the viability of an investment or a firm. It's the disparity between the anticipated cash flows and the initial investment. Let's look more closely at NPV.
We can calculate the accounting rate of return as follows:
Accounting rate of return = (Annual net Income/ Average Investment)×100
=(30,324/399,000)×100
= 7.6%
For Payback period:
Payback = Initial investment/ Annul cash flow
Annual cash flow = Annual net income + Depreciation
Deprecition = cost - salvage value/useful life
= (399,000-48,000)/9
= $39,000
Annual cash flow = 30,324 + 39,000 = 69324
Payback= 399,000/69324
= 5.755 years
For NPV:
NPV = Total present value of investment - initial investment
= 69324×PVIFA(8%, 9 years)+48,000×PV(8%, 9 years) - 399,000
= 69324×6.2469+24,011.95 - 399,000
= $58,072
For Net value recalculate if the cost of capital is 11%
NPV = Total present value of investment - initial investment
= 69324×PVIFA(11%, 9 years)+48,000×PV(11%, 9 years) - 399,000
= 69324×5.5370+18,764.39 - 399,000
= 3610.988
= $3611
Thus, the accounting rate of return is 7.6%, the payback period is 5.755 years, the Net present value is $58,072, and the net present value(11%) is $3611.
