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! :)
You take the square root of 17 so it would be 4.123105626 basically 4.12 is fine
Answer:
.083 is larger.
Step-by-step explanation:
To find out the solution, add a zero to the .08.
.080
.083
As you can see, the 3 is larger than the zero. This concludes with .083 larger than .080.
Answer:
0.9545
Step-by-step explanation:
Let an integer be x.
If x is increased by 15%, then the value of the number would be
115/100x=1.15x
If 1.15x is decreased by 17%, then the value of the number would be:
(100-17)/100×1.15x
83/100×1.15x=0.9545x
That would be the number of combinations of 11 from 23.
= 23C11 = 23! / (12! * 11!) = 1,352,078 ANswer
