Hi there! Hopefully this helps!

<h2 /><h2>Answer: 235.</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2><h2 />

First we need to <em>substitute the value of the variable</em> into the expression:

10a - 5b = 10(25) - 5(3).

Now we Multiply 10 and 25 to get <u>250</u>.

250 − 5 × 3 = 235

Multiply 5 and 3 to get <u>15</u>.

<u>250</u> − <u>15</u> = 235

<h2>Subtract 15 from 250 to get, you guessed it, 235!</h2>

Answer:

$\boxed{235}$

Step-by-step explanation:

<em>Hey there!</em>

Well given that,

a = 25

b = 3

10(25) - 5(3)

250 - 15

= 235

<em>Hope this helps :)</em>

A person on a runway sees a plane approaching. The angle of elevation from the runway to the plane is 11.1° . The altitude of th

Gnoma [55]

Answer:

The horizontal distance from the plane to the person on the runway is 20408.16 ft.

Step-by-step explanation:

Consider the figure below,

Where AB represent altitude of the plane is 4000 ft above the ground , C represents the runner. The angle of elevation from the runway to the plane is 11.1°

BC is the horizontal distance from the plane to the person on the runway.

We have to find distance BC,

Using trigonometric ratio,

$\tan\theta=\frac{Perpendicular}{base}$

Here, $\theta=11.1^{\circ}$ ,Perpendicular AB = 4000

$\tan\theta=\frac{AB}{BC}$

$\tan 11.1^{\circ} =\frac{4000}{BC}$

Solving for BC, we get,

$BC=\frac{4000}{\tan 11.1^{\circ} }$

$BC=\frac{4000}{0.196}$ (approx)

$BC=20408.16$ (approx)

Thus, the horizontal distance from the plane to the person on the runway is 20408.16 ft
