Answer:
b = 77
Step-by-step explanation:
a² + b² = c²
36² + b² = 85²
1296 + b² = 7225
b² = 7225 - 1296
b² = 5929
b = 77
Answer:
$55.80
Step-by-step explanation:
8, 16, 24, 32, 36
8=12.40, 16=24.80, 24=37.2, 32=49.6,
+4 makes it 36 so it's have of 8, so add 6.20 to the end and it's 55.80
Answer:
0.125
Step-by-step explanation:
(5 divided by 8) - ((1 divided by 4) x 2) = 0.125

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! :)
