Usually, Δ stands for a difference: if you have two quantities a₂ and a₁, their difference a₂-a₁ can be shortened as Δa.
This said, your formula is not set up correctly: the linear speed can be found with the formula:
v = ω·r
where r is the radius and <span>ω is the angular frequency, which is given by:
</span>ω = Δα / Δt
Substituting this into the one above, you find the correct formula:
<span>v = (Δα / Δt) · r
The problem gives you directly </span>Δα, which is 1/3 rad, because does not say at what angle the point started moving and at what angle it stopped.
Similarly, for the time you have Δt, which is 20 s.
Therefore, plugging in the numbers you get:
v = (Δα / Δt) <span>· r = (1/3 </span>÷ 20) × 10 = 1/6 = 0.167 cm/s
B is the answer because when you find the common denominator. B will turn into -9/24 and -5/12 is going to be -10/12

Answer:
Its just how many times can 113 go into 20 (divide them)
Step-by-step explanation:
The question that will be important to consider when exploring the problem is "What is the amount of nickels, dimes, pennies, and quarters that are put in the jar?"
<h3>How to illustrate the information?</h3>
From the information given, it should be noted that Elliot is the principal of a local high school and he is raising money for classroom supplies as he places jars in the cafeteria to collect change.
It should be noted that from the information given, we are not give the amount of each denomination. This will be important in solving the question.
Therefore, the question that will be important to consider when exploring the problem is "What is the amount of nickels, dimes, pennies, and quarters that are put in the jar?"

Answer:
56.25
Step-by-step explanation:
so basically you divide 180 by the denominator of the fraction which is 16 and multiply by the numerator, so 180 divided by 16 times 5 cool i guess
