The hypotenuse MO is found from the Pythagorean theorem to be
  MO = √(12² + 5²) = √(144+25) = √169 = 13

The sine of angle O is the ratio of the opposite side (MN=12) to the hypotenuse (MO=13). The appropriate choice is ...
  C. 12/13

Sphere and a cylinder have the same radius and height. The volume of the cylinder is 64 meters cubed.
Mrrafil [7]

Answer:

C. 128/3 meters cubed

Step-by-step explanation:

The volume of a cylinder is denoted by: V=\pi r^2h, where r is the radius and h is the height. We know it's equal to 64, so we can set that equal to V:

V=\pi r^2h

64=\pi r^2h

We know that the sphere and cylinder have the same height and radius. However, the "height" of a sphere is actually the same as its diameter, which is twice its radius. Then, we can replace h in the above equation with 2r:

64=\pi r^2h

64=\pi r^2*2r=2\pi r^3

\pi r^3=64/2=32

Now, the volume of a sphere is denoted by: V=\frac{4}{3} \pi r^3, where r is the radius. From above, we know that \pi r^3=32, so we can plug this into the equation:

V=\frac{4}{3} \pi r^3

V=\frac{4}{3} *32=128/3

Thus, the answer is C.

Last season two running back's on the college football team rush for a combined 1550 yards one rushed four times as many yards a
dmitriy555 [2]

Answer:

The player with the most runs had a rush of 1,240 yards

Step-by-step explanation:

In this question, we are asked to calculate the number of yards that was rushed by one of two person given their combined run and an extra information.

Firstly, let the person that had the smaller number of rush have a rush of x rushes. The second person has a rush of 4 times the other. This makes a number of 4x rushes

By adding both together, we have a total of 1550 yards

Mathematically, this means that x + 4x = 1550

5x = 1550

x = 1550/5 = 310 rushes

The second player had a rush of 4x and that is 4 * 310 = 1,240 rushes
