could someone help me with number 19. PLEASE! thanks. :)

Answer:

$4,500.00

Step-by-step explanation:

.05(50,000) + .08(75,000-50,000)

2,500 + 2,000

4,500

Answer:

  $4500

Step-by-step explanation:

You want to know the commission on a $75000 sale if it is 5% on the first $50000 and 8% of the amount over $50000.

The amount of commission is found by multiplying the commission rate by the applicable sale amount. For a sale amount x such that x > $50,000, the commission is ...

  C = 0.05(50000) +0.08(x -50000) = 0.08x -0.03(50000)

  C = 0.08x -1500

The commission on a sale of 75000 would be ...

  C = 0.08(75000) -1500 = 6000 -1500 = 4500

Your commission is $4500.

using exponents, On simplifying the equation, we get =4m+8.

The PEMDAS order of operations must be followed when you want to simplify a mathematical equation without using parenthesis (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). There are no parenthesis in the expression, so you may start looking for exponents. If it does, first make that simpler.

Work simplification is to develop better work processes that boost output while cutting waste and costs.

Simplifying an expression is the same as solving a mathematical issue. When you simplify an equation, you essentially try to write it as simply as you can. There shouldn't be any more multiplication, dividing, adding, or deleting to be done when the process is finished.

Given equation,

m-(8-3m)

=m-8+3m

The given statement about developing quantitative and measurable usability tests is true.

Use cases can help with developing quantitative and measurable usability tests. Use cases are scenarios that describe how a user might interact with a system or product in a specific situation.

By developing use cases, researchers can identify specific tasks that users may need to perform and design usability tests to measure how well users can perform those tasks.

This can help make the usability tests more objective and measurable, as researchers can use metrics such as completion rates, task time, and errors to assess the usability of the system or product.

The missing information is:

Carson drove a total distance of 120km, he initially has 30L of fuel on his tank, and his car efficiency is 100 cm^3/km

Remember that 1000cm^3 = 1 L

then:

100cm^3 = 0.1L

This means that he uses 0.1 L per kilometer.

The equation that shows how many liters of fuel he will have is:

initial fuel - consumed fuel.

We know that the initial fuel is 30 liters.

And the consumed fuel will be the amount of fuel he used to drive the 120 km

Remember that for each km, he consumes 0.1 L of fuel.

Then for the 120km he used 120 times 0.1 L of fuel, so he used a total of:

120*0.1 = 12 L of fuel

Then the remaining fuel in the tank is:

30 L - 12 L = 18L

There are 18 L of fuel in the tank.

Answer:

Step-by-step explanation:

given: 6 yds / sec

find the time to ride 12 miles,  so how many yards is 12 miles?

12 miles *   1760 yards / 1 mile = 21120 yds

d =r*t    d=distance , r= rate , t = time

we know the distance and the rate .. so we can find the time

d/r = t

21120/6 = t  ( in seconds)

3520 = t sec.

3520 sec *   1 min / 60 seconds   ( to convert to minutes )

3520/60=t ( in minutes)

She spends 111 minutes doing cardio workouts and 39 minutes doing weight training

Step-by-step explanation:

Call the time she spend on cardio workouts : a
And the time she spend on weight training : b

We have : a + b = 150
                 a - b = 72
Add them together, we get : a + b + (a-b) -> a+ b + a - b = 150 + 72 = 222
                                                                      = 2a
=> 2a = 222, and we have a = 111
=> b = 150 - 111 = 39

A coin is worth 50 points if collected

Step-by-step explanation:

Here, we want to calculate the worth of each coins in his video game;

Before falling into 3 pits, he had 400 points;

If he falls into a pit, 125 points is debited;

So the amount of points left after falling will be;

400-3(125) = 400-375 = 25

Now, after collecting a coin in each pit, his score is 175 points;

That means he has gained 175-25 = 150

Now kindly recall he fell into 3 pits and collected a point each in the three;

So this means, the worth of a coin is 150/3 = 50 points

The equation shown on the graph tells you the unit rate is 7. (The unit rate is the coefficient of x.)

The integral: S1 0 (-x³ - 2x² - x + 3)dx is -1/12

An integral is a mathematical operation that calculates the area under a curve or the value of a function at a specific point. It is denoted by the symbol ∫ and is used in calculus to find the total amount of change over an interval.

To evaluate the integral:

\($ \int_0^1 (-x^3 - 2x^2 - x + 3)dx $\)

We can integrate each term of the polynomial separately using the power rule of integration, which states that:

\($ \int x^n dx = \frac{x^{n+1}}{n+1} + C $\)

where C is the constant of integration.

So, we have:

\($ \int_0^1 (-x^3 - 2x^2 - x + 3)dx = \left[-\frac{x^4}{4} - \frac{2x^3}{3} - \frac{x^2}{2} + 3x\right]_0^1 $\)

Now we can substitute the upper limit of integration (1) into the expression, and then subtract the result of substituting the lower limit of integration (0):

\($ \left[-\frac{1^4}{4} - \frac{2(1^3)}{3} - \frac{1^2}{2} + 3(1)\right] - \left[-\frac{0^4}{4} - \frac{2(0^3)}{3} - \frac{0^2}{2} + 3(0)\right] $\)

Simplifying:

\($ = \left[-\frac{1}{4} - \frac{2}{3} - \frac{1}{2} + 3\right] - \left[0\right] $\)

\($ = -\frac{1}{12} $\)

Therefore,

\($ \int_0^1 (-x^3 - 2x^2 - x + 3)dx = -\frac{1}{12} $\)

The measurement of the actual part is 36 inches. The plans are drawn to a 1:192 scale, so 3/16 inch on the plans is equal to 36 inches in actual size.

When plans for a vehicle are drawn to 1:192 scale, this means that for every 1 inch on the plans, the actual size of the vehicle is 192 inches. To calculate the measurement of the actual part, we need to determine how many inches 3/16 inch is on the plans. To do this, we can use the ratio 1:192 to convert the measurement from the plans to the actual size.

1/192 = 3/16 / x

To solve for x, we can multiply both sides of the equation by 16, which gives us:

16/192 = 3/16 * 16 / x

Simplifying, we get:

1/12 = 3/x

Finally, to solve for x, we can multiply both sides of the equation by x, which gives us:

x/12 = 3

Therefore, x = 36. This means that 3/16 inch on the plans is equal to 36 inches in actual size, so the measurement of the actual part is 36 inches.
