Answer:
<u>45°</u>
Step-by-step explanation:
From the diagram :
- ∠AOC = ∠AOB + ∠BOC
- 96 = 9x - 75 + 8x - 67
- 17x - 142 = 96
- 17x = 238
- x = 238/17
- x = 14
Finding ∠BOC :
- ∠BOC = 8x - 67
- ∠BOC = 8(14) - 67
- ∠BOC = 112 - 67
- ∠BOC = <u>45°</u>
To solve this problem, first we have to figure out how many total rolls Hanna buys.
3 packs*36 rolls in each pack = 108 total rolls
2 packs*24 rolls in each pack = 48 total rolls
108 rolls + 48 rolls = 156 rolls.
Next, it says that Hanna uses 8 rolls of film. To model this in our expression, we need to subtract 8 rolls from our total amount.
156-8 = 146 rolls
Hanna has 146 rolls left.
Answer: 14.75
Step-by-step explanation:
x divided by 4
=14.75
that answer is true
The speed of the satellite is v = √(Gmp/r)
At the geostationary orbit, the gravitational force of attraction of the planet on the satellite equals the centripetal force on the satellite.
Let F = gravitational force
where G = universal gravitational constant, mp = mass of the planet, m = mass of satellite and r = radius of geostationary orbit.
Also, the centripetal force F'
where m = mass of satellite, v = speed of satellite and r = radius of geostationary orbit.
Since both forces are equal,
F = F'
So, the speed of the satellite is v = √(Gmp/r)
