Answer:

60 degrees.

Step-by-step explanation:

We use trigonometry of a right angled triangle:

Adjacent side = 20 ft, Hypotenuse = 40 ft.

cos x = adjacent / hypotenuse = 20/40 = 1/2

x = 60 degrees.

Morgarella [4.7K]

Answer:

The correct answer is C, as growth on stock E is bigger from the growth of stock B

Step-by-step explanation:

In order to resolve this problem, we must have in mind that the negative numbers are smaller when they are more distant from 0, and that positive numbers are bigger when they are more distant from 0. So, the biggest number of growth is the one that is more distant from 0.

The correct answer is C, as growth on stock E is bigger from the growth of stock B.

Answer:

V_{composite\: figure} =678.24\: in^3

Step-by-step explanation:

  • For a single cylinder:

  • radius (r) = 3 in (Given)

  • height (h) = 8 in (Given)

  • It is given that: all the three cylinders are identical, means their radii and heights are equal.

  • Thus, the volume of composite figure will be equal to three times the volume of single cylinder.

  • \implies V_{composite\: figure} =3(\pi r^2 h)

  • \implies V_{composite\: figure} =3(3.14\times  (3)^2 \times 8)

  • \implies V_{composite\: figure} =3(226.08)

  • \implies V_{composite\: figure} =678.24\: in^3
