Answer: Relative error = 50%
Step-by-step explanation:
Relative error Re = Absolute error/True value × 100%
True value = 2 scoops
Measured(used) value = 3 scoops
Absolute error Ae = measured(used) value - True value
= 3 scoops - 2 scoops
Ae = 1 scoop
Re = 1/2 × 100%
Re = 50%
Answer: You are right! Just multiply for your answer!
Step-by-step explanation:
The room is a square, meaning all four sides are 20ft long.
Because we know all the side lengths, we can find the perimeter of the square by adding the side lengths together.
(20 + 20 + 20 + 20) = 80
Now that we know the perimeter, we have to match this number to the feet of crepe paper.
We can find this by dividing the total length needed by the length a single roll provides.
80 / 8 = 10
Therefore, we know that Katie will have to buy a minimum of 10 rolls if she wants to cover the entire perimeter of the room.
Hope this helps! :)
