if u don't understand fractions u can always turn ur fractions into decimals that's what I did :)
Answer:
y = 
x²
Step-by-step explanation:
Given that y and x² are directly proportional then the equation relating them is
y = kx² ← k is the constant of proportion
When x = 2
y = k × 2² = 4k
When x = 5
y = k × 5² = 25k
Then
25k - 4k = 20 ( difference between values is 20 )
21k = 20 ( divide both sides by 21 )
k =
y = x² ← equation of proportion
Answer:
The spinner travelled 94.2 inches.
Step-by-step explanation:
In order to solve this question we first need to calculate the length of the circle, that is given by the following formula:
length = 2*pi*r
length = 2*3.14*3 = 18.84 inches
Since the spinner revolved around the circle 5 times, the distance travelled by the tip is the length of the circle multiplied by 5, as shown below:
distance = length*5
distance = 18.84*5 = 94.2 inches
The spinner travelled 94.2 inches.
The answer would be 7.99.
