. Convert 5π/3 to degrees

Answers

\pi radians is equal to 180 degrees.

Convert \pi to 180 to get the following fraction:

(5 * 180)/(3)

Multiply 5 and 180 together to get the following fraction:

(900)/(3)

Simplify the fraction.

(900)/(3) = 300

The answer is 300 degrees.
π radians  = 180 degrees

so  5π / 3 radians  = 180 / π   * 5 π / 3 = 900 / 3 = 300 degrees Answer

reserved seats for the football game cost $4.00 each and the general admission tickets for $3.00 each. after the game was over, it was found that 1787 total tickets were sold and $5792 was made. find the number of each sold

Answers

r=numbero f reserved
g=number of generall


r+g=1787

4r+3g=5792
multiply first equation by -3 and add to second
-3r-3g=-5361
4r+3g=5792 +
1r+0g=431

r=431
sub

r+g=1787
431+g=1787
minus 431 both sides
g=1356


1356 general sold
421 reserved seat sold

50/8 converted as a mixed number

Answers

50/8

Simply divide 8 into 50. That is 6.  Because 8 *6 = 48.

There would be a remainder of 2.

So  50/8 =  6 whole number    2/8.

 So the answer =    6 whole number  2/8.      As mixed fraction.

You can reduce the 2/8 to 1/4.

So  6 whole number  1/4  is also correct.
6 1/4 because do 50÷8=6 (remainder: 2) 

So it is 6 2/8. Simplify it and it will be 6 1/4.

A ball is thrown horizontally from the top ofa building 110 m high. The ball strikes the
ground 61 m horizontally from the point of
release.
What is the speed of the ball just before it
strikes the ground?
Answer in units of m/s

Answers

The speed of the ball would be 13 m/s just before it strikes the ground.

A ball is thrown horizontally from the top of a 110 m high building. 61 meters horizontally from the moment of release, the ball falls on the earth.

What is the velocity?

Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.

First of all, we get the time of aviation from the vertical component:

Here s = 110 m and g = 9.8 m/s²

s = 1/2 × gt²

Solve for t

t = √(2s/g)

Substitute the values of s = 110 m and g = 9.8 m/s² in the equation,

t = √(2×110/9.8)

t = √22.44

t = 4.7 sec

The horizontal component of velocity is constant :

v = s/t

Here s = 61 m and t = 4.7 sec

v = 61/4.7

v = 12.97 ≈ 13

Therefore, the speed of the ball would be 13 m/s just before it strikes the ground.
