allochka39001 [22]3 years ago
3 0

Answer:

Option (A)

Step-by-step explanation:

Statement 'p':

"Memorial Day is in July"

Statement 'q':

"Parallel lines intersect"

Since both the statement are joined by the 'OR',

Statements p and q will be joined by disjunction represented by the sign (∧).

Therefore, two statements will be represented as,

p ∧ q

Option (A) will be the correct option.

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%

enot [183]
400/2 = 200
200 + 20 = 220
200 - 20 = 180
Answer: He had gone 220 miles.

He was 180 miles from the finish and 220 from the start, so he was 40 miles closer to the finish than to the start.

I believe the answer is C. however, I'm not 100% sure.
Brut [27]

The answer would be C. You’re correct! Because there are 3 blue marbles @ $1 each that amounts to a possible $3 gain for Mark. Evan has the chance to get $4. Cayla also can make $3 like Mark.
