$2x +y = 20~~....(i)\\\\6x -5y = -4~~....(ii)\\\\\\\text{Multiply equation (i) by 3:}\\\\6x +3y = 60~~...(iii)\\\\(iii)-(ii):\\\\6x+3y - 6x+5y = 60-(-4)\\\\\implies 8y = 60+4 = 64\\\\\implies y = \dfrac{64}8\\\\\implies y = 8\\\\\\\text{Substitute y =8 in equation (i):}\\\\2x+8 =20\\\\\implies 2x = 20-8 = 12\\\\\implies x = \dfrac{12}2 = 6\\\\\text{Hence (x,y) = (6, 8)}$

you have a big bag of 17 marbles for our blue sticks are green 2 are red and the others are yellow what is the probability of dr

Alex Ar [27]

Answer:

3/68

Step-by-step explanation:

<u>Given</u>

Total 17 marbles
4 - blue marbles
6 - green marbles
2 - red marbles
The rest - yellow marbles

<u>Probability of drawing red first:</u>

P(red) = number of red / total number = 2/17

<u>Probability of drawing green second, without replacement:</u>

P(green) = number of green / number left in the bag = 6/16 = 3/8

<u>Probability of red and green in order:</u>

P = P(red)*P(green) = 2/17*3/8 = 3/68

A cell phone tower that is 150 ft tall sits on a mountain that

aliina [53]

Answer:

angle of elevation will be $2.14^o.$

Step-by-step explanation:

Given,

height of tower = 150 ft

height of tower = 1200 ft

So, total height of peak of tower = 1200 + 150

= 1350 ft

distance of user from cell tower = 5 miles

= 5 x 5280 feet

= 26,400 feet

Since the height of user from sea level = 400 ft

so, height of peak of tower with respect to user = 1350 - 400 ft

= 950 ft

If the angle of depression is assumed as $\theta$ , then we can write

$tan\theta\ =\ \dfrac{\textrm{height of peak of tower w.r.t user}}{\textrm{distance of user from tower}}$

$=>\ tan\theta\ =\ \dfrac{950}{26400}$

$=>\ tan\theta\ =\ 0.374$

$=>\ \theta\ =\ 2.14^o$

So, the angle of elevation will be $2.14^o.$
