Answer:

  48°

Step-by-step explanation:

The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(α) = (350 m)/(470 m) = 35/47

  α = arcsin(35/47) ≈ 48.13°

The angle of elevation of the plane is about 48°.

lara [203]

Step-by-step explanation:

Answer: 16 and 5/4 tbsp of sugar.

7 ÷ 2 = 3.5

Don't worry about the decimal for now, just find how many tbsp of sugar she needs for 6 tbsp of milk.

6 ÷ 2 = 3

3 x 5 = 15

Now, we will focus in the 0.5 tbsp of milk.

Find how much 1/2 a tbsp of milk can get for sugar.

4 1/2 tbsp of milk is 5 tbsp of sugar.

5 ÷ 4 = 1.25

So 16 and 5/4 tbsp of sugar is required.
