In this question, I’m supposed to use sin instead of tan. But the question is worded weirdly. How can I know that I’m suppose to

Answer:

Since the kite is flying, the hypotenuse side of the triangle is 32.4m, while the adjacent side is unknown.

Given the opposite and hypotenuse, we use sine to find the angle.

$\boxed{sinθ = \frac{opp}{hyp} }$

$sinθ = \frac{18.3}{32.4}$

$θ = {sin}^{ - 1} ( \frac{18.3}{32.4} )$

θ= 34.4° (1 d.p.)

Thus, the angle the kite string makes with the ground is 34.4°.

Notes:

$cosθ = \frac{adj}{hyp}$

$tanθ = \frac{ opp}{adj}$

Answer:

8, 9, 10, 11, 12

Step-by-step explanation:

Consecutive integer problems are often easier to work if you consider average values. Here, the middle of the 5 consecutive integers is their average, which is 50/5 = 10.

This tells you the integer side lengths are 8, 9, <em>10</em>, 11, 12.

Answer:

Mean = 35.56

Median = 35.5

Step-by-step explanation:

Given the data:

16 25 24 19 33 25 34 46 37

33 42 40 37 34 49 73 46 45

Reordered data :

16, 19, 24, 25, 25, 33, 33, 34, 34, 37, 37, 40, 42, 45, 46, 46, 49, 73

The mean = ΣX / n

n = sample size ; ΣX = sum of values

The mean = 658 / 18

The mean = 36.56

The Median = 1/2(n+1)th term

1/2(18+1)th term = 1/2(19)th term = 9.5 term

Median = (9th + 10th) / 2 = (34 + 37) / 2 = 35.5

For how many weeks would the class need to have car washes to earn $5000.

nikdorinn [45]

The correct answer would be for 29 weeks.
Its because if for 4 weeks the profit is $700, divide 700 and 4 which gives you $175 per week. Then divide 5000 and 175 which gives you 28.5714286. So all you have to do is round it up to the nearest whole which gives you the answer: 29 weeks.
Hope that helps. :)
