Elan Coil [88]

Answer:

cheeseburger is $3 and chips is $0.75

Step-by-step explanation:

Let price of cheeseburger be x while price of a bag of chips be y hence for the case of Nathan, we can write the equation as x+y=3.75. Similarly, for Jack, we can write it as 2x+3y=8.25

x+y=3.75 hence x=3.75-y and substituting this into the second equation we have

2x+3y=8.25

2(3.75-y)+3y=8.25

7.5-2y+3y=8.25

y=8.25-7.5=0.75

x=3.75-y=3.75-0.75=3

Therefore, price of cheeseburger is $3 and chips is $0.75

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 $2.14^o.$
