A plane traveled from California and back. It took one hour longer on the way out than it did on the way back. The plane's avera

padilas [110]

Answer:

Option D is the correct answer.

Step-by-step explanation:

Let x be the one way distance and t be the time out.

Time taken for back = t-1

We have plane's average speed out was 300 mph and average speed on the way back was 350 mph.

That is

$\frac{x}{300}=t\texttt{ and }\frac{x}{350}=t-1$

Dividing both equations

$\frac{\frac{x}{300}}{\frac{x}{350}}=\frac{t}{t-1}\\\\350t-350=300t\\\\t=7\texttt{ hours}$

Time taken for back = t-1 = 7-1 = 6 hours.

Total time taken = 7 + 6 = 13 hours

Option D is the correct answer.

Which pair of monomials has the least common multiple (LCM) of 54x2y3?

Lera25 [3.4K]

ANSWER

The correct answer is D.

EXPLANATION

If we express the monomial,

$18 {x}^{2} y$

as product of primes, we obtain:

$2 \times {3}^{2} \times {x}^{2}y$

If we express the monomial

$27x {y}^{3}$

as product of primes we obtain:

$= {3}^{3} \times x {y}^{3}$

The least common multiple of these two binomials is the product of the highest powers of the common factors.

The LCM is

$= 2 \times {3}^{3} \times {x}^{2} {y}^{3}$

$=54 {x}^{2} {y}^{3}$

Therefore the correct answer is D.

Find the circumference of a circle with an area of 28.26.<br> Show work please.

muminat

Answer:

18.84

Step-by-step explanation:

Since the formula for circumference is $C=2\pi r$ , we need to first find the radius. The formula for the radius is $r=\frac{\sqrt{A\pi } }{\pi }$ , so we will get $r=3$ . Substitute that into $C=2\pi r$ , and we get $C=18.84$ . Hope this helps!
