Answer:

The answer is k = -18

Step-by-step explanation:

This is so easy... so first you do -2k/5 - 6 = 1.2

                                                     -2k + 5(-6)/5 = 1.2

                                                      and then all that divided by 5

Step-by-step explanation:

If your town's mill rate is 8 and your assessed home value is $188,000, your town tax bill will be $1504.

Tax is a complusory amount levied by the government or an agency of the government on the sales of goods and services. It is a fomr of transfer of wealth to the government.

Town tax = (8 x $188,000) / 1000 = $1504

Answer:

45 minutes

Step-by-step explanation:

Assume task completed in total x hours

[tex]\frac{x}{10} + \frac{3}{8} + \frac{3}{12} = 1 \\ 12x + 45 + 30 = 120 \\ 12x = 45 \\ x = \frac{15}{4} = 3 \frac{3}{4}[/tex]

So q will take 45 more minutes

An example of theoretical probability from the considered option is given by: Option 2: A spinner has 8 equal sections numbered 1 to 10. The probability of spinning the number 3 is 1/8

Experimental probability calculates the probability of some event from the results of experiments.

For an event E, we get the experimental probability of that event

[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]

where, [tex]P_e(E)[/tex]is denoting experimental probability of occurrence of E.

Probability which is derived theoretically, irrespective of what outcome comes, is called theoretical probability. Probabiltiy which is based on the outcomes of experiments performed is called experimental probability.

Suppose we want to find the probability of an event E.

Then, its theoretical probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

Checking all the options to see which one gives theoretical probability:

This option uses what was observed from one result. Thus, 3/5 is experimental probability here, as there is no evidence of it being theoretical probability but enough support towards being experimental probability.

No experiment is done here, just the description of the setup of the random experiment.

Now, E = event of getting 3 on the spinner.

All spinner's parts are assumingly equally likely, we have:

Number of ways E can occur = 1

Number of ways spinner's outcome can come = 8

Thus, we get P(E) = 1/3

Thus, this option is demonstrating theoretical probability.

This is using experimental results to get the estimated probability.

Actually, assuming coin being fair, both the tail and heads being equally probable, if we take:

E = event of getting head, then as there are two results possible being Tail or Head (assuming only 2 results), and there is one way of getting head in one toss, so we get:
P(E) = 1/2 = 0.5

Thus, this option is demonstrating experimental probability instead of theoretical one.

It is using the data from one experiment. So its experimental probability. Sometimes we can get experimental probability = theoretical probability value, but still, there'd be difference of how you calculated it from the start. Usually, if calculated from experiment, then its experimental probability, and if calculated virtually and based on theories, it is theoretical probability.

Thus, an example of theoretical probability from the considered option is given by: Option 2: A spinner has 8 equal sections numbered 1 to 10. The probability of spinning the number 3 is 1/8

Answer:

Step-by-step explanation:

The label on the car's antifreeze container claims to protect the car between -40°C and 125°C.

So inequality which models this situation will be -40°C < T < 125°C

Now we have to show this inequality in Fahrenheit temperature with the help of [tex]C=\frac{5}{9} (F-32)[/tex]

So the compound inequality in Fahrenheit temperature will be

Answer:

109.88 ft² (nearest hundredth)

Step-by-step explanation:

Formulae

To find the area of the lawn that is not watered, subtract the area of the 2 circles from the area of the rectangle.

From inspection of the diagram

Substituting the values into the area of a rectangle formula, and solving for r:

⇒ 512 = 2r × 4r

⇒ 512 = 8r²

⇒ r² = 64

⇒ r = ±8

As distance is positive, r = 8 ft

Area of one circle = π8² = 64π  ft²

Therefore,

Area not watered = area of rectangle - 2 × area of circle

                             = 512 - 2(64π)

                             = 109.88 ft² (nearest hundredth)

The Algebraic equations (x - 20)² and x² - 20 have an equal value My number is 6.

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

I think of a number, if I subtract 10 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result.

Let the number be x.

If I subtract 20 from my number that is x - 20 then square the result that is (x-20)².

And if I square my number that is x² then subtract 20 from the result that is x² - 20.

Both the result are the same then we have

         (x - 20)² = x² - 20

x² - 20x + 100 = x² - 20

  -20x + 100 = -20

                  x = 6

My number is 6

The computation of the figure illustrates that 0.47 expressed as a fraction in simplest form is 43/90.

From the information given, let a = 0.47. Now 10a = 4.777 .... equation i

100a = 47.77 ..... equation ii

Subtract equation i from ii

100a - 10a = 47 - 4

90a = 43

Divide both side by 90

90a/90 = 43/90

a = 43/90

Step-by-step explanation:

According to the rational factorization.

The degrees of arc which Cody he walks clockwise around the pool from point D to point E is 105 degrees.

The inscribed polygon in a circle is the polygon of which each corner point is on the circle.

The image shows the location of ladders around a circular pool. Cody walks clockwise around the pool from point D to point E. In the given image the value of x i,

[tex]2x+8=86\\2x=86-8\\x=\dfrac{78}{2}\\x=39^o[/tex]

Thus, the angle C and angle B are the supplementary angle. Thus,

[tex]m\angle C=m\angle D\\7y-4=360-(3y-6)\\7y+3y=360+6+4\\10y=370\\y=37[/tex]

3y-6 is the inscribed angle which intercept the arc DE. Thus,

[tex]\text {arc } DE= 3y-6\\\text {arc } DE= 3(37)-6\\\text {arc } DE= 105[/tex]

Thus, the degrees of arc which Cody he walks clockwise around the pool from point D to point E is 105 degrees.
