A laptop computer is purchased for $2000. After each year, the resale value decreases by 25%. What will the resale value be after years?
Use the calculator provided and round your answer to the nearest dollar.

$[]

Answers

Answer:

2000? ... assume $2000

Resale Value = $2000*(1 - 0.25)t/yr

where: t = number of year after purchase

at t = 3 yr

Resale Value = $2000*(1 - 0.25)3 = $843.75

checking: at t = 0 $2000 (purchase price)

at t = 1 yr $2000 - 0.25*$2000 = $2000 - $500 = $1500

at t = 2 yr $1500 - 0.25*$1500 = $1500 - $375 = $1125

at t = 3 yr $1125 - 0.25*$1125 = $1125 - $281.25 = $843.75

Answer:

Step-by-step explanation:

Sum of angles of a triangle = 180

x + (180 - 105) + (180 -140) = 180

x + 75 + 40 = 180

x = 180 -75 - 40

Step-by-step explanation:

If you graph the equation you can see that it doesn't cross the x-axis. It doesn't go lower than y=1. If you don't have a graphing calculator use Desmos. Also the +1 at the end of the equation tells you that it won't go lower than y=1.

Answer:

Never your answer is 0

Step-by-step explanation:

The equation creates what's called a parabola the line curves up the 1 represents the y axis so the line curves up from the y axis point 1 never touching the x axis

y-5x-2 ... Show your work.
A) (-4,-22)

C) (-4; 6)
D) (4;18)
no links and pls show ur work

Answers

I’m not sure if you mistyped but if you meant y=5x-2 then here is your answer:

So the equation is y=mx + b

-2 is your b meaning that it is your y intercept so you can plot it on the y axis (0,-2)

Then your slope is 5. Since your slope is positive, in order to go to the left side you can change both the denominator and numerator into negatives. So 5/1 = -5/-1

Slope = rise/run

So each time you go down 5, you go to the left once. So if you go to -4, then you will have to go down 4 times as well so 4 x 5 = 20, so you go down 20 points. You are already at (0,-2) so if you go down 20 points then you are at (-4,-22)

Therefore the correct answer is (-4,-22)

The mean age of 11 women in an office is 31 years old.
The mean age of 6 men in an office is 29 years old.
What is the mean age (nearest year) of all the people in the office?

Answers

Answer: 30.2

Explanation:

The mean is calculated by taking the sum of the values and dividing by the count.

For instance, for the 6 women, with the mean being 31, we can see that the ages summed to 186:

186

6

=

31

And we can do the same for the men:

116

4

=

29

And now we can combine the sum and count of the men and women to find the mean for the office:

186

+

116

10

=

302

10

=

30.2

Step-by-step explanation:

9514 1404 393

Answer:

  30

Step-by-step explanation:

The total of the ages of the 11 women is 11·31 = 341. The total of the ages of the 6 men is 6·29 = 174. Then the total of the ages of all 17 people in the office is ...

  341 + 174 = 515

and their average age is ...

  515/17 ≈ 30.294 ≈ 30

The mean age of the people in the office, to the nearest year, is 30.

Classify the object with the given side lengths as acute, obtuse, right, or not a triangle.
16, 21, 28
Right
Acute
Obtuse
Not a triangle

Answers

Answer:

We have to first see that the given lengths makes a triangle or not by using a+b > c in which a,b and c are

length of sides of a triangle lets check out

16 + 21 = 37 > 28

21 + 28 = 49 > 16

16+ 28 = 44 > 21

As because the statement fits correct in the lengths given so its a triangle

So we can say that the triangle is scalene by means of measurements

but cant be a right angle as by taking the pythagorean triplet

= a^2 + b ^ 2 = c^2

lets see if a=16, b = 21 and c = 28

So a^2 + b^2

= 256 + 441

= 697

but c^2

= 28^2 = 784

As 441 =/= 784

So The triangle lengths cant be a right angled triangle

So 1/2 of possibility is the traingle acute and 1/2 of the possibilty that the triangle is obtuse

Now you can find the correct triangle on the basis of acute or obtuse angle by drawing with given length of sides of triangle

Maria y juan deben realizar el mapamundi en medio pliego de cartulina para la tarea de sociales pero cada uno tiene un cuarto de cartulina maria le dice a su compañero que si unen los cuartos de cada uno obten dran el medio pliego que necesitan . Maria tine razon justifica tu rrespuesta

Answers

Answer:

Cuando María afirma que si unen sus dos cuartos de cartulina obtendrán el medio pliego que necesitan, esto es:

Verdadero.

Step-by-step explanation:

Para entender mejor el ejercicio vamos a utilizar números cada vez que se habla de cantidades de cartulina, por lo tanto, María y Juan tienen 1/4 de cartulina cada uno, es decir, 1/4 * 2, y necesitan 1/2 pliego para poder realizar su tarea, por lo tanto, con la afirmación de María sobre unir los dos cuartos de cartulina, en caso de que sea verdadero, ocurrirá que la suma de los dos cuartos dará el medio pliego, como se muestra a continuación:

Total de cartulina de María y Juan = [tex]\frac{1}{4}+\frac{1}{4}[/tex]Total de cartulina de María y Juan = [tex]\frac{4+4}{16}[/tex]Total de cartulina de María y Juan = [tex]\frac{8}{16}[/tex]

Procedemos a simplificar el fraccionario obtenido, sacando mitad tanto en el numerador como en el denominador:

Total de cartulina de María y Juan = [tex]\frac{4}{8}[/tex]Total de cartulina de María y Juan = [tex]\frac{2}{4}[/tex]Total de cartulina de María y Juan = [tex]\frac{1}{2}[/tex]

Como puedes ver al final, la cantidad de cartulina de ambos, al ser sumada, da como resultado el 1/2 (medio) pliego que necesitan para su tarea de sociales, por lo cual la afirmación de María es correcta.

Based on historical data, your manager believes that 43% of the company's orders come from first-time customers. A random sample of 243 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is between 0.2 and 0.39?

Answers

Answer:

Following are the solution to the question:

Step-by-step explanation:

[tex]p = 0.43\\\\n = 243\\\\\sigma =\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.43 (1 -0.43)}{243}}=0.0013[/tex]

z-score for [tex]\hat{p}=0.2[/tex] will be:

z score for will be:

[tex]z=\frac{\hat{p}-p}{\sigma}=\frac{0.39 - 0.43}{0.0013}=-30.76[/tex]

[tex]P(0.2 <\hat{p}< 0.39) = P(-176.92 < z < -30.76)[/tex] using excel method to calculate the value.

what is the HCF of 3000 and 525 answer with process​

Answers

Answer:

The HCF is 75

Step-by-step explanation:

Here, we want to get the highest common factors of the two numbers

To do this, we have to write the numbers as the product of their prime factors

We have;

3,000 = 2 * 2 * 2 * 3 * 5 * 5 * 5

525 = 3 * 5 * 5 * 7

now looking at this, we can see that in both numbers, we can have 3 * 5 * 5 taken out as it is common to both numbers

This represents the highest common factor of the two numbers

and that is 75
