Answer:

Step-by-step explanation:

Adjacent to the undetermined angle is 6, and the hypotenuse has been given. We can conclude, after looking at our SOHCAHTOA, that we will be using cosine(CAH) to solve this problem.

Let the unspecified angle be $\theta\\$ (This sign is called theta, which is just a sign for angle)

Lets start!

cos $\theta\\$ = adj/hyp

cos $\theta\\$ = 6/13

$\theta\\$ = $cos^{-1}$ (6/13)

$\theta\\$ = 62.5

$\theta\\$ = 63

Hope that helped!

During summer vacation, you charge people 8$ per hour for swimming lessons and 20$ registration fee. If you make 52$ one day, ho

zepelin [54]

Answer:

You taught for 4 hours

Step-by-step explanation:

Let this number of hours be x. Then:

Total earned = $20 + ($8/hr)x

Equate this to $52 and then solve the resulting equation for x:

20 + 8x = 52

Then 8x = 32, and x = 4. You taught for 4 hours.

I beg of you solve it. A small Plane can travel 120 mph in still air. The plain can fly 700 miles with the wind in the same that

Fiesta28 [93]

Answer:

speed of the wind, w = 20 mph

Step-by-step explanation:

Let,

s = speed in still air = 120 mph

w = wind speed = ?

t = travel time in hours

Plane traveling with the wind, we have:

(v + w)t = 700

(120 + w)t = 700 ------------------(equation 1)

Plane traveling against the wind, we have:

(v - w)t = 500

(120 - w)t = 500 --------------------(equation 2)

From equation 1, make t subject of formula,

t = 700/(120 + w) -------------------(equation 3)

From equation 2, make t also subject of formula,

t = 500/(120 - w) ---------------------(equation 4)

It is the same t in both equations, so equating equation 3 and 4

700/(120 + w) = 500/(120 - w)

Solve for w.

500(120 + w) = 700(120 - w)

60000 + 500w = 84000 - 700w

500w + 700w = 84000 - 60000

1200w = 24000

w = 24000/1200

w = 20 mph
