Answer:

The speed of the jet is 410 mph.

Step-by-step explanation:

The jet and the passenger plane flew in opposite directions.

Given that the passenger plane flew at a speed of 450 mph, then after 11 hours, the passenger plane will fly (450 × 11) = 4950 miles.

Again, given that after 11 hours the passenger plane and the jet are 9460 miles apart.

Therefore, in 11 hours the jet flew (9460 - 4950) = 4510 miles.

Hence, the speed of the jet is $\frac{4510}{11} = 410$ mph. (Answer)

Answer:

9/2 inches or 4 1/2

Step-by-step explanation: Try to find the unit rate FIRST. Divide 2 on both sides and you will get that ONE INCH = 3/2 miles.

Since you need to know the distance for 3 inches, MULTIPLY both SIDES by 3, and you will get 3 INCHES = 9/2 MILES.

HURRY I NEED HELP!!! Solve triangle JKL round to the answer to the nearest tenth

creativ13 [48]

Answer:

It's Option A.

Step-by-step explanation:

Using the Cosine Rule:

cos < K = (3.9^2 - 1.9^2 - 2.8^2) / (-2 *1.9*2.8)

= 3.76 / -10.64

= - 0.3534.

m < K = 110.7 degrees.

Using the Sine Rule:

3.9 / sin 110.7 = 2.8 / sin <J

sin J = 2.8 sin 110.7/ 3.9 = 0.6716

m < J = 42.2 degrees

So m < L = 180 - (110.7 + 42.2)

= 180 - 152.9

= 27.1 degrees

Dafna11 [192]

As given by the question

There are given that the profit of $16 milonin 2018 and $24 milion in 2019.

Now,

To find the profit,

$\frac{24-16}{16}\times100$

Then,

$\begin{gathered} \frac{24-16}{16}\times100=\frac{8}{16}\times100 \\ =\frac{1}{2}\times100 \\ =0.5\times100 \\ =50\% \end{gathered}$

Hence, the correct option is C.
