Answer:
11/75 & 17/75
Step-by-step explanation:
divide the two numbers and put it in a fraction and simplify it to get your answer
Answer:
A) 109 degrees
The answer is 109 degrees because each opposite angle added equals 180°. 180-71= 109

Answer:
a) Check Explanation
b) α = - 0.32 rad/s²
Step-by-step explanation:
a) The first drop rises higher than the second drop because the speed of the tire has reduced from what it was during the first turn to a lower value during the second turn. This will most likely be due to how bicycle tires are set up, plenty frictional elements to tamper and reduce the speed of the bike until it is pedalled again.
Note that the speed with which the drops of water rise are both equal to the corresponding tangential speeds of the tire at those points in time. And since the tangential speed of the tire reduces in between turns, the height travelled by the drops too, reduces.
b) To calculate the angular acceleration for the two cases.
The kinetic energy of the drops of water while on the tire is converted to the energy used to attain the respective heights that they attain.
(1/2)mv² = mgh
v = √(2gh)
For the first drop
h₁ = 54.0 cm = 0.54 m
r = 0.381 m
v₁ = √(2gh₁)
v₁ = √(2×9.8×0.54) = 3.253 m/s
w₁ = (v₁/r)
w₁ = (3.253/0.381) = 8.538 rad/s
For the second drop
h₂ = 51.0 cm = 0.51 m
r = 0.381 m
v₂ = √(2gh₂)
v₂ = √(2×9.8×0.51) = 3.162 m/s
w₂ = (v₂/r)
w₂ = (3.162/0.381) = 8.300 rad/s
Using the equations of angular motion,
w₂² = w₁² + 2αθ
θ = 2π
8.3² = 8.538² + 4π (α)
α = -0.32 rad/s²
Negative because it is angular deceleration
Hope this Helps!!!
Answer:
Umm... Try turning it on and off? If that doesn't work, I don't know.
Step-by-step explanation:
Step-by-step explanation:
Well, let's walk through it, shall we?
3x − 5 = 4 + 3x
Our first step is to simplify both sides of the equation.
3x − 5 = 4 + 3x
3x + −5 = 4 + 3x
3x − 5 = 3x + 4
Then, we subtract 3x from both sides.
3x − 5 − 3x = 3x + 4 − 3x
−5 = 4
FInally, we'll add 5 to both sides.
−5 + 5 = 4 + 5
0 = 9
In conclusion, your answer is:
This would be false. x = -3 is not a solution to 3x - 5 = 4 + 3x
