The tax on the chair is $7.50.

A tax is a mandatory financial charge or other sort of levy imposed by a governmental entity on a taxpayer in order to fund government spending and related public expenses.

The tax rate is the ratio at which a firm or individual is taxed in a tax system. A tax rate can be presented in numerous ways: statutory, average, marginal, and effective.

Let the cost of the chair be $150 and the assumed tax rate be 5%.

In this case, the tax on the chair will be:

= Tax rate × Cost of chair

= 5% × $150

= 0.05 × $150

= $7.50

If the average number of babies born at a private hospital's maternity wing is 6 per hour. The probability that three babies are born during a particular 1-hour period in this maternity wing is 0.09.

Mean = 6 per hours

Number of babies = 3 babies

Hence,

Now let determine the probability

Let x represent the probability

Pr(X=3) = e^-6 × 6^3 ÷ 3!

Pr(X=3) =0 .535410 ÷ 6

Answer:

  116

Step-by-step explanation:

Given the ratio 1.2 : 29, you want x in the equivalent ratio 4.8 : x.

Equivalent ratios can be written as a proportion:

  1.2/29 = 4.8/x

Multiplying by 29x, we have ...

  1.2x = 29(4.8)

Dividing by 1.2 gives ...

  x = 29(4.8/1.2) = 29(4) = 116

The ratio is the same as 4.8 to 116.

Answer:

  -12 m/km

Step-by-step explanation:

You want to know the average elevation change per kilometer given the elevation changes from 876 meters to 672 meters over a distance of 17 kilometers.

The average elevation change per kilometer is found by dividing the elevation change by the number of kilometers. The elevation change is the difference between the ending elevation and the starting elevation.

  rate of change = ((end elevation) -(start elevation))/(distance)

  = (672 m -876 m)/(17 km) = (-204 m)/(17 km) = -12 m/km

The average elevation change is -12 meters per kilometer traveled from the lodge.

1 rad x 180/pi =57.296 deg

so the answer is 744.845

In order to add these numbers, first let's write all of them with the same number of decimal places:

17.34 = 17.340

8.03 = 8.030

0.009 = 0.009.

Then, let's add all algarisms that are in the same position in each number:

0 + 0 + 9 = 9

4 + 3 + 0 = 7

3 + 0 + 0 = 3

7 + 8 + 0 = 15 (5 plus 1 to next algarism)

1 + 0 + 0 (+ 1) = 2

Answer:

28 miles

Explanation:

The equation that describes the relationship between the fare and the number of miles is:

f = 2.25 + 0.20(m - 1)

Where f is the fare and m is the number of miles.

So, if the taxi fare was $7.65, we can replace f by 7.65. Then:

7.65 = 2.25 + 0.20(m - 1)

Therefore, we can calculate the number of miles by solving the equation for m. So, subtracting 2.25 from both sides:

7.65 - 2.25 = 2.25 + 0.20(m - 1) - 2.25

5.4 = 0.20(m - 1)

Dividing by 0.20, we get:

Finally, add 1 to both sides:

27 + 1 = m - 1 + 1

28 = m

So, he travels 28 miles in the taxi

The combination that gives the most profit exists 12 VIP rings and 12 SST rings (900 / day).

This is a linear programming problem.

The objective function is profit R, which has to be maximized. [tex]$R=40 \mathrm{~V}+35 S$[/tex]

being V: number of VIP rings produced, and S : number of SST rings produced.

The restrictions are

Amount of rings (less or equal than 24 a day): [tex]$V+S \leq 24$[/tex]

Amount of man-hours (up to 60 man-hours per day):[tex]$3 V+2 S \leq 60$[/tex]

The number of rings of each type exists a positive integer: [tex]$V, S \geq 0$[/tex]

We get 3 points, in which 2 of the restrictions exists saturated. In one of these three points lies the combination of V and S that maximizes profit.

The points and the values for the profit function in that point are:

Point 1: V=0 and S=24

[tex]$R=40 \mathrm{~V}+35 S=40 \cdot 0+35 \cdot 24=0+840[/tex]

R = 840

Point 2: V=12 and S=12

R = 40 V+35 S [tex]=40 \cdot 12+35 \cdot 12=480+420[/tex]

R = 900

Point 3: V=20 and S=0

R = 40 V+35 S [tex]=40 \cdot 20+35 \cdot 0=800+0 \\[/tex]

We can see two graphs and we need to determine the reason why graph A IS a function, and graph B is NOT a function.

To achieve that, we can proceed as follows:

1. A function is a relation in which for each element of the domain we have only (exactly) one element of the range.

2. The domain of a function is the values for x for which the function is defined, and the range is those values for y that result when the function takes values for x and after following the rule of the function (the values for which the function is defined).

3. To determine if a graph is a function, we can use the vertical line test. Given the above definitions, this test tells us that if a vertical line passes through a graph at more than a point, then the relation is NOT a function.

4. Now we can use the Vertical Line Test on each graph as follows:

As we can see from the graph, the vertical line passes through only one point (one value for y associated to x). We can see that the open circle indicates that the function is not defined for the value while the solid circle indicates that the function is defined for that value.

For instance, for x = -1 the value of the function is y = 0 (and not y = -1 - see the open circle). We have a similar case for x = 1 (y = 1) (not y = 0).

Therefore, graph A IS a function.

In this case, we can say that the vertical line passes through more than one point in most of the values. However, we can say that there are some values where the line passes through one point - from x = -3 to x = -2 (included) -, and for values greater than 2 (x>2).

However, since the vertical line test indicates that the line passes through more than a point (there are more than a value, y, for each x) then Graph B is NOT a function.

Therefore, in summary, we can say that using the method of the vertical line test, Graph A IS a function, while Graph B is NOT a function.

The dimensions of the enclosure that can be erected at minimum cost are 21.25 feet by 42.50 feet

From the question, the given parameters are

Area = 903 square feet

Shape = rectangle

From the question, we understand that:

One side of the area would be enclosed by the external wall of the store

If the dimensions of the area are Length (L) and Width (W), then we have

Area = LW

Perimeter = 2L + W

Rewrite as

A = LW

P = 2L + W

Substitute 903 for A in A = LW

LW = 903

Make W the subject

W = 903/L

Substitute W = 903/L in P = 2L + W

P = 2L + 903/L

Differentiate the equation

So, we have

P' = 2 - 903/L²

Set to 0

2 - 903/L² = 0

So, we have

903/L² = 2

This gives

L² = 903/2

Divide

L² = 451.5

Take the square roots

L = 21.25

Substitute L = 21.25 in W = 903/L

W = 903/21.25

Evaluate

W = 42.50

Hence, the dimensions of the enclosure are 21.25 feet by 42.50 feet
