Answer:

If we are going with the information you supplied, all the statements are false except -(-5) = 5

Step-by-step explanation:

-1 - 51 = -52

-52 =/= -5

-(-5) = 5

5 = 5

-151 =/= -5

1 - 5 = -4

-4 =/= -5

Galactic Rotation Speed. We are located about 27,000 light-years from the galactic center and we orbit the center about once eve

Alexxandr [17]

Answer:

speed = 796142.197 km/hr

Step-by-step explanation:

solution

we consider here orbit around galactic center is circular so

circumference formula will be here

circumference C = 2πr ........1

here we know r = 27000

circumference C = 2 π × 27000

C = 169560 light year

we travel 169560 light year in 230000000 years

so distance will be

distance = $\frac{169560}{230000000}$

distance = 0.00073721 light year/year

and we know 1 year = 8760 hours

so 1 light year = 9.46027 × $10^{12}$ km

sped of moving is

speed = 0.00073721 × 9.46027 × $\frac{10^{12}}{8760}$ km/hr

speed = 796142.197 km/hr

Answer:

Step-by-step explanation:

You can use the cosine rule to solve this problem:

cos(∠KLJ) = (KL² + JL² - KJ²)/(2*JL*KL) = 21463/21960 = 0.97737

∠KLJ = cos⁻¹(0.97737) = 12.2°
