Answer:

  A. This is a linear function because there is a common difference of 2

Step-by-step explanation:

Differences are ...

The differences of 2 are common, so this is an arithmetic function.

Option: A is the correct answer.

A.   This is a linear function because there is a common difference of 2.

Linear function--

A function is said to be linear if the rate of change is constant.

i.e. the function is increasing by a fixed constant.

Here the table is given by:

Hour (x) Number of Customers f(x)

    1               3

    2                  5

    3                  7

From the table of values we observe that as the value of increasing by 1 the value of y is increasing by 2.

i.e. the rate of change is constant i.e. 2.

Also, the common difference is 2.

since,

5-3=2

and 7-5=2

Hence, the table represents a linear function.

Answer:

Perimeters is 32.44 unit and area is 30 square unit.

For this case we have to define trigonometric relations of rectangular triangles that, the cosine of an angle is given by the leg adjacent to the angle on the hypotenuse of the triangle. That is, according to the data of the figure we have:

[tex]Cos (45) = \frac {6} {h}[/tex]

Where:

h: It's the hypotenuse

So:

[tex]\frac {\sqrt {2}} {2} = \frac {6} {h}[/tex]

We cleared h:

[tex]h \sqrt {2} = 6 * 2\\h \sqrt {2} = 12\\h = \frac {12} {\sqrt {2}}[/tex]

We rationalize:

[tex]h = \frac {12 \sqrt {2}} {(\sqrt {2}) ^ 2}\\h = \frac {12 \sqrt {2}} {2}\\h = 6 \sqrt {2}[/tex]

Answer:

Option C

ANSWER

[tex] 6\sqrt{2} \: units[/tex]

EXPLANATION

This is an isosceles right triangle.

The two legs of an isosceles right triangle are equal, hence each of them is 6 units each.

Let h be the hypotenuse, then from the Pythagoras Theorem,

[tex] {h}^{2} = {6}^{2} + {6}^{2} [/tex]

[tex]{h}^{2} = {6}^{2} \times 2[/tex]

Take square root of both sides;

[tex]{h} = \sqrt{ {6}^{2} \times 2 } [/tex]

[tex]{h}= \sqrt{ {6}^{2} } \times \sqrt{2} [/tex]

[tex]{h} = 6\sqrt{2} \: units[/tex]

The correct answer is C

Answer:

x=7

Step-by-step explanation:

Equate the angles 7x-7 and 4x+14 and solve:

7x-7 = 4x+14

7x-4x = 14+7

3x = 21

x = 7

Answer:

x = 7

Step-by-step explanation:

Alternate interior angles are equal. Alternate interior  angles look like these two angles.

7x - 7 = 4x + 14             Add 7 to both sides

7x - 7 + 7 = 4x + 14+7   Combine

7x = 4x + 21                  Subract 4x from both sides

7x-4x = 4x - 4x + 21      Combine

3x = 21                          Divide by 3

3x/3 = 21/3                    Do the division

FICA taxes on a W-2 form include Social Security and Medicare taxes, summed up at a standard rate of 7.65% of gross wages. To know the total FICA taxes paid, one must multiply the gross wages by 7.65% based on the provided rates.

The question is asking for the total FICA taxes paid, which includes both Social Security and Medicare taxes. The information provided indicates that the employee pays 6.2% for Social Security and 1.45% for Medicare, which are standard rates for FICA tax deductions. To calculate the total amount of FICA taxes, add these percentages together to get a combined rate of 7.65%. If you know the gross wages, you multiply this amount by 7.65% to find the total FICA tax contribution on your W-2 form. If the actual gross wages earned are unknown, the calculation cannot be completed without this figure.

It is important to note that your employer also matches the FICA tax contributions, and some economists argue that this employer contribution effectively reduces employees' wages, meaning that employees might bear the total cost of these taxes indirectly.

Step-by-step explanation:

The 007C requires the least significant two digits be in the range 35-39. In order for the 10-thousands digit to be zero, the sum of 1000 times the least digit of Genet's number and 2 times the hundreds digit must result in a sum with no thousands. About the only way to do that is to make the least digit 9 and the hundreds digit 5.

Answer:

The answer is (D): 2 h 52 min

Step-by-step explanation:

write these equations separately as functions:

A(x)=15+0.02m

B(x)=4.69+0.08m

Since we want to find when they are equal, set them equal to each other:

15+0.02m=4.69+0.08m

simplifying this equation gives

10.31+0.02m=0.08m

subtract 0.02m from both sides

10.31=0.06m

divide both sides by 0.06

m=171.833 etc approximately equals 172 minutes

172 min/60=

2 hours and 52 min

Hope this helps!

Answer:

  2 h 52 min

Step-by-step explanation:

Let m represent the number of minutes that will make the plans have equal cost. Equating the two plan costs, we have ...

  15.00 + 0.02m = 4.69 + 0.08m

  10.31 = 0.06 m . . . . . subtract 4.69+0.02m

  10.31/0.06 = m = 171.8333... ≈ 172 . . . . minutes at equal cost

There are 60 minutes in an hour, so ...

  172 minutes = 120 minutes + 52 minutes = 2 hours + 52 minutes

Plan A will cost the same as Plan B for 2 h 52 min of usage.

Answer:

The equation is 5x + 10y = 800

Step-by-step explanation:

* Lets explain what is the equation and how can we make one

- The equation is a mathematical statement that two things are equal.

- It consists of two expressions, one on each side of an equal sign (=).

* Lets solve the problem

- There are two types of vehicles, large one and small one

- The cost of washing the small vehicle is $5

- The cost of washing the larger vehicle is $10

- They collected from washing both is $800

- To make an equation for the amount collected let the number of the

 small vehicles is x and the number of the large vehicles is y

∵ x is the number of the small vehicles were washed

∵ y is the number of the large vehicles were washed

∵ The cost of washing the small vehicle is $5

∵ The cost of washing the larger vehicle is $10

∴ The money collected from the small vehicles = 5 × x = 5x

∴ The money collected from the large vehicles = 10 × y = 10y

- find the total money collected from both

∴ The amount of money collected from both = 5x + 10y

∵ The amount of money collected is $800

- Equate the two expressions above

∴ 5x + 10y = 800

* The equation is 5x + 10y = 800

Answer:

1/5; 20%

Step-by-step explanation:

If she is only choosing 2 shirts, and they both have to be white, the probability of choosing those 2 white shirts out of 10 white shirts is 2/10 or, equivalently, 1/5.  In percent form, this is 20%

The probability of a woman randomly choosing two white shirts from a collection of 14 shirts (10 white and 4 red) is approximately 49%, derived through the process of combinations calculation in the field of probability.

The question relates to the field of probability in mathematics. To calculate her probability of selecting two white shirts, we first need to understand the number of total possible outcomes when she is selecting 2 out of the 14 shirts. This is represented by the combination formula C(n, r) = n! / r!(n-r)!, where n is the total number of items to choose from and r is the number of items to choose. Using this combination formula, we find that there are C(14, 2) = 91 total possible combinations of shirts she could end up with.

Next, we need to find the number of combinations that involve her picking 2 white shirts. As there are 10 white shirts, this is represented by C(10, 2) = 45. So, the probability of her taking two white shirts is then the number of desired outcomes divided by the total number of outcomes, or 45 / 91 which simplifies to approximately 0.4945 or 49% when rounded to the nearest whole percent.

  1.5

Step-by-step explanation:

The coordinate values of point J are 1.5 times those of point A, so if dilation is about the origin, the scale factor is 1.5.

If the dilation is about some other point, this problem statement does not contain enough information to tell what the scale factor might be.

[tex]\boxed{x=1, \y=-1, \ z=2}[/tex]

We will use the Gaussian elimination method to solve this problem. To do so, let's follow the following steps:

Step 1: Let's multiply first equation by −2. Next, add the result to the second equation. So:

[tex]\begin{array}{ cccc }~~ x&+~~2~ y&-~~~~~ z&~=~-3\\&-~~~5~ y&+~~3~ z&~=~11\\~~ x&-~~~~~ y&+~~~~ z&~=~4\end{array}[/tex]

Step 2: Let's multiply first equation by −1. Next, add the result to the third equation. Thus:

[tex]\begin{array}{ cccc }~~ x&+~~2~ y&-~~~~~ z&~=~-3\\&-~~~5~ y&+~~3~ z&~=~11\\&-~~~3~ y&+~~2~ z&~=~7\end{array}[/tex]

Step 3: Let's multiply second equation by −35, Next, add the result to the third equation. Therefore:

[tex]\begin{array}{ cccc }~~ x&+~~2~ y&-~~~~~ z&~=~-3\\&-~~~5~ y&+~~3~ z&~=~11\\&&+~~\frac{ 1 }{ 5 }~ z&~=~\frac{ 2 }{ 5 }\end{array}[/tex]

Step 4: solve for z, then for y, then for x:

[tex] \frac{ 1 }{ 5 } ~ z & = \frac{ 2 }{ 5 } \\ \\ \boxed{z & = 2}[/tex]

[tex]-5y+3z &= 11\\-5y+3\cdot 2 &= 11\\ \\ \boxed{y &= -1}[/tex]

By substituting [tex]y=-1 \ and \ z=2[/tex] into the first equation, we get the [tex]x[/tex]. So:

[tex]x+2(-1)-2=-3 \\ \\ x-2-2=-3 \\ \\ \boxed{x=1}[/tex]

Answer:

The final angle is 124°

Step-by-step explanation:

1. Getting the total sum of all angles:

The general rule to get the sum of all interior angles is as follows:

sum of interior angles = (n-2)*180

where n is the number of sides

We know that a heptagon has 7 sides, therefore:

sum of interior angles of a heptagon = (7-2)*180 = 5 * 180 = 900°

2. Getting the missing angle:

We know that the total sum of all 7 angles is 900°

We also know that the sum of 6 of those angles = 776°

This means that:

measure of the last angle = 900 - 776

measure of last angle = 124°

The final angle is 124°

Hope this helps :)

area=6×11.4×13÷2=444.6 yd²

Final answer:

The area of a regular hexagon with an apothem of 11.4 yards and a side of 13 yards is approximately 444.6 square yards when rounded to the nearest tenth.

Explanation:

To find the area of a regular hexagon with a given apothem and side length, you can use the formula for the area of a regular polygon:

Area = (1/2) × Perimeter × Apothem

In this case, the perimeter of the hexagon can be calculated by multiplying the length of one side by 6 (since a hexagon has 6 sides). Therefore, the Perimeter = 13 yards × 6 = 78 yards.

Now, plug the values into the area formula:

Area = (1/2) × 78 yards × 11.4 yards

Area = (1/2) × 889.2 square yards

Area = 444.6 square yards

So, the area of the regular hexagon is approximately 444.6 square yards, when rounded to the nearest tenth.
