Answer:

x = 73.3

y = 46.2

Step-by-step explanation:

Reference angle (θ) = 39°

Adjacent = 57

Hypotenuse = x

Opposite = y

Recall: SOHCAHTOA

✔️To find x, apply CAH:

Cos θ = Adjacent/Hypotenuse

Plug in the values

Cos 39° = 57/x

x × Cos 39° = 57

x = 57/Cos 39°

x = 73.3 (nearest tenth)

✔️To find x, apply TOA:

Tan θ = Opposite/Adjacent

Plug in the values

Tan 39° = y/57

57 × Tan 39° = y

y = 46.2 (nearest tenth)

Answer

1/2

Step-by-step explanation:

Explanation:

You have a right triangle with legs of 11 and 60. The hypotenuse is unknown.

Use the pythagorean theorem to find the hypotenuse.

[tex]a^2 + b^2 = c^2\\\\11^2 + 60^2 = c^2\\\\121 + 3600 = c^2\\\\3721 = c^2\\\\c^2 = 3721\\\\c = \sqrt{3721}\\\\c = 61\\\\[/tex]

The ramp is exactly 61 inches long.

Answer:

C. Paired t-interval for means

Step-by-step explanation:

The answer to this question is the paired t interval for means. The reason is because both of these events are independent. One of the event starts as the other event gets to it's completion. The population standard deviation is not also not known. This makes the paired t interval for means more suitable

[tex]arc \ length = 2\pi r \frac{\theta}{360} = \\\\[/tex][tex]2 \pi *9 * \frac{135}{360} =21.205[/tex]

[tex]\frac{3\pi }{4} =\frac{3*180}{4}=135[/tex]

The average monthly wage for the entire workforce of the business is $7489.09.

The mathematical average of a group of two or more numbers is called the mean. There are two different sorts of means that can be calculated: the arithmetic mean and the geometric mean. The arithmetic mean is calculated by adding all of the numbers in a set and dividing by the total number of integers in the set.

Given, The six departments of a company consisting of 22, 32, 18, 16, 10, and 12 employees have equal monthly salaries of $7200, $7600, $6900, $8200, $7800, and $7400 respectively.

First, calculate the total monthly salary

22*7200 + 32*7600 + 18*6900 + 16*8200 + 10*7800 + 12*7200  dollars.

Total monthly salary = $823,800

Then divide this sum by the total number of employees  

 22 + 32 + 18 + 16 + 10 + 12

Total number of employees = 110

the mean monthly salary of all the employees  = [tex]\frac{Total salary}{total number of employee}[/tex]

the mean monthly salary of all the employees  = 823800/ 110

the mean monthly salary of all the employees = 7489.0909

Therefore, the mean monthly salary of all the employees of the company is $7489.09.

Answer: x=3

Step-by-step explanation:

5x=7x-6

6+5x=7x

6=7x-5x

6=2x

solve for x which x=3

Answer:

x = 3

Step-by-step explanation:

Set the equations equal to each other:

5x = 7x - 6

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Division

Addition

Subtraction

~

Subtract 7x from both sides of the equation:

[tex]5x (-7x) = 7x (-7x) - 6\\5x -7x = -6\\-2x = -6[/tex]

Next, divide -2 from both sides of the equation:

[tex]\frac{-2x}{-2} = \frac{-6}{-2}\\ x = \frac{-6}{-2}[/tex]

*Remember that, when you divide two negative numbers, your answer will be positive:

[tex]x = \frac{-6}{-2} = 3[/tex]

If Raj was getting a 5% commission, he would make 24000 * 5% = $<<240005.01=1200>>1200 on $24,000 of sales.

If he is now getting a 6.5% commission, he will make 24000 * 6.5% = $<<240006.5.01=1560>>1560 on $24,000 of sales.

Thus, Raj will make 1560 - 1200 = $<<1560-1200=360>>360 more on $24,000 of sales with his new commission rate of 6.5% than he did with his old commission rate of 5%.

Answer:

  28 toys

Step-by-step explanation:

Ben has 50 toys, of which 15 are new, 9 are favorites, and 2 are new and favorites. You want to know the number that are neither new nor favorite.

The number of new toys includes (new and favorite) and (new and not favorite). That is ...

  15 = 2 + new and not favorite

So ...

  new and not favorite = 15 -2 = 13

Likewise, the number of favorite toys includes (new and favorite) and (not new and favorite). That is ...

  9 = 2 + not new and favorite

  not new and favorite = 9 -2 = 7

The total of 50 toys includes ...

  total = (new and favorite) + (new and not favorite) + (not new and favorite) + (not new and not favorite)

  50 = 2 + 13 + 7 + (not new and not favorite)

Then the number of (not new and not favorite) is ...

  not new and not favorite = 50 -2 -13 -7 = 28

These are the toys that Ben gives away.

Ben gives away 28 toys.

Dilation factor by 3 is bigger than 1 = Expansion

Originally 6, 4

6*3 = 18

4*3 = 12

Answer:

18,12

Step-by-step explanation:

W (1, -2), X (7,-2), Y (7,-6), and Z (1, -6).

To dilate the shape, multiply it's coordinates by the scale factor.

W'(3,-6), X'(21,-6), Y'(21,-18), Z(3, -18)

The distance formula: [tex]d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]

plug W'(3,-6) and X'(21,-6) in to get the length

[tex]\sqrt{(3-21)^2+(-6-(-6))^2}=\sqrt{(-18)^2 +0^2}=\sqrt{324} =18[/tex]

plug X(21,-6) and Y(21,-18) to get the width

[tex]\sqrt{(21-21)^2+(-6-(-18))^2}=\sqrt{0^2 +12^2}=\sqrt{144} =12[/tex]
