While traveling across flat land, you notice a mountain directly in front of you. The angle of elevation to the peak is 1.5°. Af

Answer:

0.68 miles

Step-by-step explanation:

Let's say that the height of the mountain is h

The distance between the mountain and the car, after moving 23 miles closer to the mountain, will be x (let's pose it as x for now)

tan(1.5°) = opposite/adjacent = h/23 + a

=> h = (23 + a)tan(1.5°) ---- (1)

tan(13°) = h/a

=> h = a(tan(13°)) ---- (2)

Now since h is common among the two equations, we can equate them;

$\left(23+a\right)\tan \left(1.5^{\circ \:}\right)=a\left(\tan \left(13^{\circ \:}\right)\right),\\23\tan \left(1.5^{\circ \:}\right)+\tan \left(1.5^{\circ \:}\right)a=\tan \left(13^{\circ \:}\right)a,\\\\\tan \left(1.5^{\circ \:}\right)a-\tan \left(13^{\circ \:}\right)a=-23\tan \left(1.5^{\circ \:}\right),\\\left(\tan \left(1.5^{\circ \:}\right)-\tan \left(13^{\circ \:}\right)\right)a=-23\tan \left(1.5^{\circ \:}\right),\\\\$

$a=\frac{23\tan \left(1.5^{\circ \:}\right)}{\tan \left(13^{\circ \:}\right)-\tan \left(1.5^{\circ \:}\right)} = 2.94249...$

$h = 2.94249tan\left(13^{\circ }\right) = 0.67932\dots$

The height of the mountain ≈ 0.68 miles

PLEASE HELP ASAP……..

Answer:

4x+2y = 14 The original equation

2y = 14-4x Subtract 4x from both sides

2y = -4x+14 Rearrange so x is first

y = -2x+7 Divide everything by 2

Explanation:

The steps above practically explain everything needed, so there's not much to add. The standard form is Ax+By = C while slope intercept form is y = mx+b

In the case of y = -2x+7, we have a slope of m = -2 and y intercept of b = 7. This means (0,7) is one point on the line. Use the slope to move down two and to the right one unit to arrive at (1, 5) as another point on this line.

I have 11 red marbles and 4 blue marbles in a bag if I choose one what color will it be

Veronika [31]

Answer:

11/15 red, 4/15 blue

Step-by-step explanation:

There are 15 marbles in all so that is the denominator.

The numerator is the number of marbles for each color.

So...

11 red marbles / 15 total marbles

4 blue marbles / 15 total marbles
