Answer:

  tan(α+β) ≈ -5.8688

Step-by-step explanation:

You can use the formula for the tangent of the sum of angles, or you can use a calculator to find the angles. The latter is much simpler.

  tan(α+β) = tan(arccos(0.871) +arccos(0.338))

  tan(α+β) ≈ -5.8688

Note that the two angles total slightly more than 90°, so the tangent of their sum is a large negative number.

The use of trig identities also requires a calculator, and many more steps.

The tangent of the angle can be found from the cosine using ...

  tan(x) = √((1/cos(x))² -1)

  tan(α) = √((1/0.871)² -1) ≈ √(1.1481056² -1) ≈ 0.56404479

  tan(β) = √((1/0.338)² -1) = √(2.9585799² -1) ≈ 2.7844559

And the tangent of the sum of angles is ...

  tan(α +β) = (tan(α) +tan(β))/(1 -tan(α)tan(β))

  tan(α+β) = ((0.56404479 +2.7844559)/(1 -(0.56404479)(2.7844559))

  tan(α+β) = 3.3485007/(1 -1.5705579)

  tan(α+β) ≈ -5.8688

Additional comment

The approximate angles are ...

  α ≈ 29.4249°

  β ≈ 70.2448°

Then α+β ≈ 99.6699°

Answer:

  1/216

Step-by-step explanation:

The ratio of volumes of similar shapes is the cube of the scale factor. The filled portion of the cone is similar to the entire cone.

If the filled height is 1/6 of the total height, the scale factor for linear dimensions is 1/6.

The scale factor for the volume is the cube of the scale factor for linear dimensions. it is ...

  (1/6)³ = 1/216

The volume of the filled portion of the cup is 1/216 of the volume of the cup.

Answer:

1. How much profit would the restaurant make by selling 100 burritos?

Answer: The restaurant would make $550

2. How much money would the restaurant take in by selling 100 burritos

Answer: The restaurant would take in $800

Step-by-step explanation:

First we have to add all the negatives.

-1.50 + -1.00

= -2.50

Now that we have that, we just need to multiply both the 8 dollars and the -2.50 by 100.

8 * 100 = 800

-2.50 * 100 = -250

Now we have the answer for the second question.

The restaurant would take in $800 before the cost of the ingredients.

But now we need to find the profit. (Which is the amount of money they made minus the cost of the ingredients and meat)

800 - 250 = 550

So the restaurant will make $550 in profit.

Hope this helped! :D

Answer: is C

Step-by-step explanation:

Answer: The truck is carrying 55 large boxes and 60 small boxes

Step-by-step explanation:

Let x represent the number of large boxes

Therefore,

The number of small boxes = 115 - x

[tex]\therefore[/tex] According to the question

60x + 25(105 -x) = 4550

60x + 2625 - 25x = 4550

35x = 4550 - 2625

35x = 1925

x = 55

Number of large boxes = x = 55

Number of small boxes = 115 - 55 = 60

The time taken by the boat to travel 32 miles downstream is 2.1 hours and for upstream 3.56 hours.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

Given that:-

The time taken by the boat upstream will be calculated as:-

( B + W ) Td = D

( 12 + 3 ) Td = 32

( 15 ) Td = 32

Td = 32 / 15 = 2.1 hours

The time taken by the boat downstream will be calculated as:-

( B - W ) Tu = D

( 12 - 3 ) Tu = 32

9 Tu = 32

Tu = 32 / 9 = 3.56 hours.

Therefore the time taken by the boat to travel 32 miles downstream is 2.1 hours and for upstream 3.56 hours.

Using a system of equations, it is found that the average of sheep A and sheep D is of 191 pounds.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are the weights of the sheep, given by A, B, C and D.

Sheep A and sheep B have an average weight of 150 pounds, hence:

[tex]\frac{A + B}{2} = 150[/tex]

A + B = 300 -> B = 300 - A

Sheep B and sheep C have an average weight of 127 pounds, hence:

B + C = 254

300 - A + C = 254

C - A = -46.

A - C = 46.

C = A - 46.

Sheep C and sheep D have an average weight of 168 pounds, hence:

C + D = 336

A - 46 + D = 336.

A + D = 382.
