Mathematics
1 answer:
hoa [83]4 years ago
5 0

Answer:

Step-by-step explanation:

If arccos (√3 / 2) = β, then cos β = adjacent side / hypotenuse = √3 / 2.  This tells us immediately that the adjacent side length is √3 and the hypotenuse is 2.  Via the Pythagorean Theorem, we know that the third side is 1.  

This information rules out the 1st and 3rd answer choices.

Because cos 30° = adj / hyp = √3 / 2, we can conclude that the correct answer is the 4th one:  30°, 60°, 90°

A rectangular prism with dimensions 5 inches by 13 inches by 10 inches was cut to leave a piece as shown in the image. What is t
vesna_86 [32]

Answer:

Volume of the piece in the picture = 350 cubic inches

Volume of the remaining piece = 300 cubic inches

Step-by-step explanation:

Given question is incomplete without the picture; here is the picture as an attachment.

Volume of the rectangular prism = Length × width × height

V = 5 × 13 × 10

  = 650 cubic inches

Now volume of the piece given in the picture = Volume of prism at the base + Volume of the prism with triangular base

= 10×5×1 + (\text{Area of the triangular base})\times (\text{Height})

= 50 + \frac{1}{2}\times (12\times 5)\times 10

= 50 + 300

= 350 cubic inches

Volume of the other piece = 650 - 350

                                            = 300 cubic inches

Simone has 5 employees in her flower shop. Each employee works 6 4⁄15 hours per day. How many hours, in total, do the 5 employee
satela [25.4K]

Answer:

94/3 = 31.333

Step-by-step explanation:

The total hours worked = the amount of employees * hours worked

First I converted the mixed fraction 6\frac{4}{15} into \frac{94}{15}

Then I multiplied it by the amount of employees.

\frac{94}{15} * 5 = \frac{94}{3}

= 31.33333
