<h2>Firstly, we let for the number to be any number or letter.</h2>
Step-by-step explanation:
The above pictures shows working.
Answer:
θ = 2π
Rotational period = T
so the angular velocity is:
w=2πT
v=Dt
D=vt
Step-by-step explanation:
3/7. There are 7 temperatures, so the denominator is 7. However, only 3 of them were above 75, so the numerator is 3.
The number of hours she practices each day is unknown, so let's call it x.
She practices dancing x hours each day she goes to practice.
Since she practices 3 days per week, in a week she practices 3x hours.
In two weeks she practices 2(3x) hours, or 6x hours.
We are told she practices 12 hours in 2 weeks, so 6x must equal 12.
The equation is
6x = 12
We can solve it by dividing both sides by 6.
x = 2
She practices 2 hours per day.
Check:
2 hours per for 3 days = 2 * 3 hours = 6 hours in 1 week.
In 2 weeks, she practices 2 * 6 hours = 12 hours.
Our solution is correct.
Y=3/2x-1
