Step-by-step explanation:

To calculate a fraction, it is almost the same as calculating a number normal to the power. The numerator and denominator of the fraction are multiplied as many times as possible indicated by its exponent, then:

    [tex]\boldsymbol{\sf{\left(\dfrac{1}{9}\right)^{2}=\dfrac{1\times1}{9\times9}=\cfrac{1}{81} }}[/tex]

Therefore the fraction 1/81 is already in reduced form, so it is no longer possible to simplify it.

The polynomial which models the company's sales in thousands of dollars will be 4.4x² + 4x.

A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.

The profit is given as,

Profit = Selling price - Cost price

Sales volume for an auto manufacturer may be calculated as 7.8x² + 3.2x + 3.5 and costs as 3.4x² - 0.8x + 3.5.

The net profit by subtracting cost from sales will be

Net profit = (7.8x² + 3.2x + 3.5) - (3.4x² - 0.8x + 3.5)

Net profit = 7.8x² + 3.2x + 3.5 - 3.4x² + 0.8x - 3.5

Net profit = 4.4x² + 4x

The polynomial which models the company's sales in thousands of dollars will be 4.4x² + 4x.

The total sales done by Madelyn Logan is $975,000.

Madelyn Logan earns $58,000 in total.

Madelyn Logan's total commissions are;

$58,000 - $19,000 (base salary) = $39,000.

That is, $39,000 equals 4% of her sales.

So,

0.04x = $39,000, in which x would be the total sales amount.

Then, x = $39,000 /0.04

x = $975,000.

Therefore, Madelyn Logan must sell the goods of worth $975,000. for making the amount of $58,000.

Using proportions, it is found that their total monthly payment is of $2,887.37.

A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.

Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.

For this problem, the payments are given as follows:

Hence:

2165.62 + 0.0833 x 6478.5 + 0.0833 x 2186 = $2,887.37

Their total monthly payment is of $2,887.37.

By changing units from calories per minute to watts, we conclude that your power output is 1.11 Watts.

Power is the ratio between energy consumed and the time in which it was consumed.

Here we know that you consume 111 calories per mile, and you run a mile in 7 minutes, then your power is:

P = (111 cal)/(7 min) = 15.86 cal/min

Now, we know that:

1 watt = 14.33 cal/min

Then we can rewrite our power as:

P = 15.86 cal/min = (15.86/14.33) W = 1.11 W

Your power output is 1.11 watts.

The solution of the equation P = A/(1 + rt) for r is r = (A/P - 1)/t

The equation is given as

P = A/(1 + rt)

Multiply both sides of the equation by (1 + rt)

So, we have

P(1 + rt) - A

Divide both sides by P

So, we have

1 + rt = A/P

Subtract 1 from both sides

rt = A/P - 1

Divide by t

r = (A/P - 1)/t

Hence, the solution of the equation P = A/(1 + rt) for r is r = (A/P - 1)/t

The two equations that represent the remaining angle relationships are

x = 2(y + z) - 20 and x = 3z - 20

From the question, we are to determine the two equations that represent the remaining angle relationships

From the given information, we have that

x is the largest angle, y is the next largest angle and z is the smallest angle

Also, from the information,

"The measure of the largest angle is 20 degrees less than twice the sum of the measure of the other two angles"

That is,

x = 2(y + z) - 20

and

"The largest angle is 3 times the smaller angle minus 20 degrees"

x = 3z - 20

Hence, the two equations that represent the remaining angle relationships are x = 2(y + z) - 20 and x = 3z - 20

Answer:

can you add a picture of the triangle

Step-by-step explanation:

We can rearrange it to the standard form perimeter a = s - b - C/2

In arithmetic, what is a perimeter?

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.

The answer to your question is a = s - b - C/2

To solve for "a", we must get "a" on it's own side of the equal sign. We can first subtract "s" from both sides:

0 = a + b + C/2 - s

Then, we can subtract a from both sides:

-a = b + C/2 - s

Finally, we divide both sides by -1, so a is by itself.

a = -b - C/2 + s

And we can rearrange it to the standard form:

a = s - b - C/2
