Wires are attached to a pole to make it more secure. The diagram shows one of those wires having a length of 220 feet. The angle
LuckyWell [14K]
The wire, the pole and the segment joining the leg of the pole to the wire in the ground form a right triangle whose hypotenuse is the wire, and the side opposite to the angle 36° is the pole.

By right triangle trigonometry, sin36°=(opposite side)/(hypotenuse.)

Substituting, we have 0.588=(opposite side)/220, thus the length of the opposite side, which represents the length of the pole, is 

                                       0.588*220 ft=129.3 ft

rosijanka [135]

Answer:

1.15

Step-by-step explanation:

Multiply each shot by its point value. Then add. Divide this sum by the total number of shots taken.

288*2 + 79*3 + 340*0 = 813

----------------------------------------

288 + 79 + 340 = 707

813 / 707 = 14.992

The weighted average is approximately 1.15 points per shot.

John has a storage bin in the shape of a rectangular prism the storage bed is still in the and 1/2 ft long 2 ft wide and 2 ft ta
Phoenix [80]

We know, volume of rectangular prism is given by :

V = lbh\\\\V=\dfrac{1}{2}\times 2\times 2\ ft^2\\\\V=2\ ft^2

Volume of cubic box :

v=a^3\\\\v=(\dfrac{1}{2})^3\ ft^3\\\\v=\dfrac{1}{8}\ ft^3

Number of cubes can be filled :

N=\dfrac{V}{v}\\\\N=\dfrac{2}{\dfrac{1}{8}}\\\\N=16

Therefore, 16 cubes can be put in the bin.

Hence, this is the required solution.
