a. The return on investment is $700.

b. The payment should be $20.

c. The total value is $10,680.

Calculation of the return on investment, payment and total value:

a. Since the return on investment is 7%

And, the invested amount is $10,000

So, the return on investment should be

= 7% of $10,000

= $700

b. Since the expense ratio is 0.2%

So, here the payment be like

= 0.2% of $10,000

= $20

c. The total value should be

= $10000-$20 +$700

= $10680

Answer:

A = -5

Step-by-step explanation:

The change in the temperature after 4 1/4 hour is -6.8 C.

Given :

A freezer in a lab is set so that the temperature changes at a rate of –1.6 C every hour.

Temperature :

Temperature is the degree of hotness or coldness of an object.

The degrees must contain any units like kelvin , centigrade etc .

Change in temperature after 4 1/4 hours = change rate for hour * number of hours.

= -1.6 C * 4 1/4

= -1.6 C * 4.25

= -16 / 10 C * 425 / 100

= -16 * 425 / 10 * 100 C

= -6800 / 1000 C

= -68 / 10 C

Answer: x = 25

Step-by-step explanation:

(x-7) = 36/2

x-7 = 18

x = 18 +7

x = 25

Answer: x = 1 and x = 13.

Step-by-step explanation: To solve the equation (x - 7)^2 = 36, we can first rewrite the equation as x^2 - 14x + 49 = 36.

Next, we can rewrite the equation as x^2 - 14x + 13 = 0.

To solve for x, we can then use the quadratic formula:

x = (-b +/- sqrt(b^2 - 4ac)) / (2a)

where a = 1, b = -14, and c = 13.

Substituting these values into the formula, we get:

x = (14 +/- sqrt(14^2 - 4(1)(13))) / 2

x = (14 +/- sqrt(196 - 52)) / 2

x = (14 +/- sqrt(144)) / 2

x = (14 +/- 12) / 2

The values of x are therefore 1 and 13.

Therefore, the correct answer is x = 1 and x = 13.

Sales Tax added to the cost of the computer is 178.34 pounds

What is sales tax?

Sales tax is a tax imposed by the government on the price of a commodity for the sale of that commodity. Imposing sales tax on a product increases the price of the product. Nowadays, sales tax has been replaced by Goods and Service Tax (GST).

Here, sales tax is added to increase the price of the computer.

The graph of the equation, y = -50x + 300, is given in the attachment below.

The equation of a line, where m is the slope or unit rate, and b is the y-intercept or starting value, is expressed as y = mx + b in the slope-intercept form.

Given the situation above, first determine the value of the starting value / y-intercept (b) and that of the slope / unit rate (m).

The starting value / y-intercept is b = 300.

The slope / unit rate is m =  - 50 [this is negative because the distance from home reduces as she drives at the speed of 50 mph]

To write the equation, substitute m = -50 and b = 300 into y = mx + b:

Answer:

x = 2 , x = 5

Step-by-step explanation:

assuming you mean

[tex]\sqrt{9x-9}[/tex] = x + 1 ( square both sides to clear the radical )

([tex]\sqrt{9x-9}[/tex] )² = (x + 1)² ← expand using FOIL

9x - 9 = x² + 2x + 1 ( subtract 9x from both sides )

- 9 = x² - 7x + 1 ( add 9 to both sides )

0 = x² - 7x + 10 ← factor the quadratic

consider the factors of the constant term (+ 10) which sum to give the coefficient of the x- term (- 7)

the factors are - 2 and - 5 , since

- 2 × - 5 = + 10 and - 2 - 5 = - 7 , then

(x - 2)(x - 5) = 0

equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 5 = 0 ⇒ x = 5

As a check

substitute these values into the equation and if both sides are equal then they are the solutions.

x = 2

left side = [tex]\sqrt{9(2)- 9}[/tex] = [tex]\sqrt{18-9}[/tex] = [tex]\sqrt{9}[/tex] = 3

right side = 2 + 1 = 3

left side = right side , so x = 2 is a solution

x = 5

left side = [tex]\sqrt{9(5)-9}[/tex] = [tex]\sqrt{45-9}[/tex] = [tex]\sqrt{36}[/tex] = 6

right side = 5 + 1 = 6

left side = right side, so x = 5 is a solution

The measure of an exterior angle of a triangle is equal to the measure of its neighboring interior angle if both measure 90 degrees, according to the theory of supplementary angles.

If the sums of two angles equal 180 degrees, they are said to be supplementary.

However, two angles do not need to be near one another in order to be complementary.

If two angles' measures sum up to 180 degrees, they are said to be supplementary.

A triangle's outside angle complements the neighboring inner angle.

The adjacent internal angle will therefore likewise be 90 degrees if the exterior angle is.

The line has a 17/5 slope and y has a value of 51 which will be (15, 51).

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

The general equation for every straight line is y = MX + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y -axis).

So, the water level rises by 17 cm in 5 minutes.

Then in 15  minutes, the water will rise by:

15 * 17/5

3*17

51

Then (x, y) will be (15, 51).

Obtaining the slope as follows:

Formula: m = y1 - y2/x1 - x2

m = y2 - y1/x2 - x1

m = 17  - y/5 - x

m = 17/5

To solve the quadratic equation 3w^2 - 12w = -12, we can use the quadratic formula:

x = (-b +/- sqrt(b^2 - 4ac)) / (2a)

In this case, a = 3, b = -12, and c = -12. Plugging these values into the formula, we get:

w = (-(-12) +/- sqrt((-12)^2 - 43(-12))) / (2*3)

Simplifying, we get:

w = (12 +/- sqrt(144 + 144)) / 6

w = (12 +/- sqrt(288)) / 6

w = (12 +/- sqrt(288)) / 6

w = (12 +/- 16.97) / 6

w = (12 +/- 16.97) / 6

w = 28.97/6 or -4.97/6

On Thursday when the correct time is 5:00h, watch shows 4:24h.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

The watch is set at 11:00 h on Sunday.

Also, the watch loses 8 seconds in every hour.

To determine the time in watch on Thursday,

In one day total hours = 24 hours.

from Sunday 11:00 to Thursday 11:00

Total hours = 24 x 4 = 96 hours

And 11:00 to 5:00, total = 6 hours

Total hours = 96 + 6 = 102 hours

Since, watch loses 8 seconds in 1 hour

So in 102 hours watch losses = 102 x 8 = 816 seconds

816 seconds = 816/60 minutes = 13.6 minutes

The watch loses 13.6 minutes in 102 hours.
