8 0

Answer: Unlike Terms

Step-by-step explanation:

Both numbers have one same letter which is n, but both are different because the first 8 has m, and the Second 8 has p. So, they're unlike terms.

The distance between planets in two stellar systems is 1.6x10^6 miles. If a spaceship is able to travel at 8,400 miles per hour,

emmainna [20.7K]

Answer:

Yes it will be able to make the journey in under a year.

Step-by-step explanation:

To find out how many hours it will take $1.6*10^2$ and divide by 8400

$\frac{1.6*10^2}{8400} = 190.476 hr$

So it will take the space ship 190.476 hours to make the trip.

Next, ask our self, how many hours are in a year?

To find out multiply 365 * 24 = 8760 hr

The 365 = number of day in a year. The 24 = number of hours in a day.

Knowing how many hours there are in a year and how long the trip will take tells us that the journey can be made under a year since there are 8760 hours in a year and we know we can make it there in 190.476 hr traveling at 8400 mph

Find all solutions for a triangle with a = 6,b = 8, and A = 150°

levacccp [35]

Answer:

6/sin 150 = 8 / sin B

Step-by-step explanation:

6/sin 150 = 8 / sin B

sin 150 = 1/2 so you cross multiply to get 6 sin B = (1/2) • 8

6 sin B = 4

sin B = 4/6

B = inverse sin (4/6) = 42º or 138º

But both of those add to 150 to go over 180 so there are no solutions.

Back in geometry, you had that the larger angle of a triangle is opposite the longer side, right? You can see that 150º can't be opposite 6 because then the angle opposite 8 would have to be larger than 150º which is impossible for a triangle.

Function,d(r) = 0.034r , is used to convert Russian rubles in United States dollars, and function, e(d) = 0.76d , is used to con

Dahasolnce [82]

We have two functions, one which converts rubles to USD and one which converts USD to euros. If we want to convert from rubles to euros, we could just convert it to USD and then euroes.

2000₽ ⇒ USD
$d(r)=0.034r\\d(2000)=0.034(2000)=68$

$68 USD ⇒ €
$e(d)=0.76d\\e(68)=0.76(68)=\boxed{51.68}$

Extra: If you wanted, you could create a function to convert rubles into euroes.
Just substitute that 0.034r for d in e(d) = 0.76d and... $e(r)=0.76(0.034r)=0.02584r$
