It would be 16 more 6th graders that are not in either band or orchestra.
  15 6th Graders in band
  9 6th Graders in both classes
+18 6th Graders in orchestra
-----
42 6th Graders in either class

  100 6th Graders in total
 -42 6th Graders in either class
-------
58 6th Graders in neither class
 58-42= 16 more 6th Graders that are not in either class

A cylindrically shaped space station is rotating about the axis of the cylinder to create artificial gravity. The radius of the
erica [24]

Answer:

8%

Step-by-step explanation:

The maximum change happens when all 500 people moves form outer surface to the station center. When all of them are at the surface, the total moment of inertia is:

I = I_s + 500I_p = 3*10^9 + 500m_pr_p^2=3*10^9 + 500*70*82.5^2=3.24*10^9

When they are at the axis, the total moment of inertia is only the station's, which is 3*10^9

By the law of angular momentum conservation:

I_1\omega_1 = I_2\omega_2

\omega_2/\omega_1 = I_1/I_2 = \frac{3.24*10^9}{3*10^9} = 1.08

So the angular speed changes by 0.08 of itself, or 8%

I need this solved please
ss7ja [257]

Answer:

x = 23

y = 128

Step-by-step explanation:

Theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

98 = 2x + 3x - 17

115 = 5x

x = 23

Angles 3x - 17 and y form a linear pair, so they are supplementary.

3x - 17 + y = 180

3(23) - 17 + y = 180

69 - 17 + y = 180

52 + y = 180

y = 128
