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.

Answer:

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

Answer:

First, if we look at these angles, we can see that they are vertical.

Vertical angles are congruent(meaning they measure the same degrees).

So let's set up an equation where -2x - 6 is equal to 40°, because they are vertical angles.

-2x - 6 = 40°

Solve for x!

Get rid of constants by performing the inverse operation of subtraction which is addition(because 6 is negative).

Make sure to apply this to both sides!!

(Add 6 to both sides)

+6           +6

-2x = 46

Now, we isolate x by getting of x's co-efficient.

To do that, we also perform the inverse operations.

The inverse operation of multiplication is division (since -2 is being multiplied by x).

(Divide -2 from both sides)

÷ -2 ÷ -2

x = -23

Therefore, x measures -23°.

Answer:

x = -23

Step-by-step explanation:

Vertical Angle Theorem

A pair of opposite angles formed by intersecting lines.

Vertical angles are congruent.

⇒ -2x - 6 = 40

Add 6 to both sides:

⇒ -2x = 46

Divide both sides by -2

⇒ x = -23

Answer:

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

Using proportions, it is found that the total purchase price of the bracelet is of $10,769.

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 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)

Step-by-step explanation:

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.

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.

Answer:

Now plot those points in graph and find intersection hope it helps you.......

The rational function shown in the graph is:

[tex]y = \frac{x - 6}{x - 5}[/tex]

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]

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.
