The height of the balloon from ground is 100√3m.

Justification:

<u>The above situation forms a right angled triangle ABC in which length of cable 200m indicates the hypotenuse side and angle of inclination is 60°</u>.

So, In ΔABC

sinθ = p/h

sin60° = AB/AC

√3/2 = AB/200

AB = 200√3/2

AB = 100√3m.

<u>Note</u>: Figure attached with answer.

Answer:

  100√3 ≈ 173 m

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relevant relationships.

  Sin = Opposite/Hypotenuse

  sin(60°) = height/(200 m)

  height = (200 m)sin(60°) ≈ 173.205 m

The height of the balloon is about 173 meters.

The intensity of a sound varies inversely where of its distance from the source at a distance of 1 meter the intensity of a jet
xz_007 [3.2K]

Answer:

  1/250 W/m² or 0.004 W/m² or 4 mW/m²

Step-by-step explanation:

The cargo worker is (50 m)/(1 m) = 50 times the reference distance. The intensity varies as the inverse of the square of the distance, so will be ...

  (1/50)²×(10 W/m²) = 10/2500 W/m² = 1/250 W/m²

This might be more conveniently written as 4 mW/m².

Each week carrie works 40 hours she spend 15% of her time at register
VLD [36.1K]
Please, share the goal of the problem.  If Carrie works 40 hours per week and spends 15% of her time at the register, how much time does she NOT spend at the register?  

Subtract 15% from 100%; the result is 85%.  Now find 85% of 40 hours:

0.85(40 hours) = 34 hours.

Please note that I invented part of this problem.  Next time, share all of the info so that someone can help you solve YOUR particular problem.

10g - 4 (g - 2) + 11 = 1
sergij07 [2.7K]

Answer:

g = -3

Step-by-step explanation:

10g-4(g-2)+11=1

1) 10g-4g+8+11=1  Combine like terms

2) 6g+8+11=1

3) 6g+19=1

4) 6g=-18   To continue the process of getting the variable by itself, we have to get rid of 19. So we are going to subtract 19 from 19 to get 0, and whatever we do to the other side, so we subtract 19 from 1 to get -18.

5)6g=-18    To get the variable by itself, instead of mutiplying, we will divide by 6 on both sides to get... g=-3! Hope this helps!
