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! :)
Answer:
Step-by-step explanation:
LCM of 3 and 6 = 6
2/3 = (2×2) / (3×2) = 4/6
4/6 = (4×5) / (6×5) = 20/30
5/6 = (5×5) / (6×5) = 25/30
Hence, 21/30, 22/30, 23/30 and 24/30 are four rational numbers between 2/3 and 5/6.
Answer:
x = 1.6
Step-by-step explanation:
4x + 6x - 6 = 10
10x - 6 = 10
+6 +6
10x = 16
10x/10 = 16/10
x = 1.6
I’ll answer this later but use an equation 180 degrees
