maria [59]

Answer:

  8 minutes

Step-by-step explanation:

The amount in the glass after m minutes can be described by ...

  a = 4 + 3/2m

We want to find m when a=16, so ...

  16 = 4 + 3/2m

  12 = 3/2m . . . . . subtract 4

  8 = m . . . . . . . . . multiply by 2/3

It will take 8 minutes to fill the glass.

Solve the following equation by using the addition principle. Check the solution.
omeli [17]

Answer:

y = 11/20

Step-by-step explanation:

-4/5 + y = -1/4

Add 4/5 to each side

-4/5  +4/5 + y = -1/4+4/5

y = -1/4 + 4/5

Get a common denominator

y = -1/4 *5/5   + 4/5 *4/4

y = -5/20 + 16/20

y = 11/20

Check

-4/5 +11/20 = -1/4

Get a common denominator

-4/5*4/4 + 11/20 = -1/4*5/5

-16/20 +11/20 = -5/20

-5/20 = - 5/20

Step-by-step explanation:

the angle of depression is the measure of the angle from the horizontal downwards from the top of the flag pole.

this angle is alternate to ∠ A and is congruent to ∠ A

using the sine ratio in the right triangle

sin A = \frac{opposite}{hypotenuse} = \frac{25}{31} , then

∠ A = sin^{-1} ( \frac{25}{31} ) ≈ 53.8° ( to 1 d.p )

Angle of depression ≈ 53.8°
