The linear speed of the object is the ratio between the measure of the arc it had traveled and the time. For the length of the arc,
2π x (20 m) x (0.2 rad/ 2π rad) = 4 meters
Divide this by the time, 10 s. Thus, the linear speed is equal to 0.4 m/s.

Y=3.25x should be the most probable choice because 6.50 is the price of 2 pounds of candy and once it’s divided by 2 the equation will show how much the unit rate is or the price of each pound of candy.
Answer:
3/2
Step-by-step explanation:
formula k = y/x
comes from
y = kx
k = constant of variation
when y = 3 , x = 2
k = 3/2
Answer:
6 + 0.05
Step-by-step explanation:
To write a number in expanded form, you write each value of the digits by themselves. For example, let us say that that the number is 250.96 . To write in expanded form, you are essentially stretching out all the non-zero numbers, and keeping them separate (but in the same value), As in the example, we will write it out as expanded form:
250.96 = 200 + 50 + 0.9 + 0.06
