Answer:
23.38 inches of fabric was used for headband for each player.
9.43 inches of fabric was used for wristband for each player.
Step-by-step explanation:
Given that:
Total fabric used on headbands = 888.44 inches
Total number of players = 36
Total number of coaches = 2
Total number of people for whom headbands were made = Number of players + Number of coaches = 36 + 2 = 38
Amount of fabric used for each one = Total fabric used for headbands divided by Total number of people
Amount of fabric used for each one = 
Similarly,
Total fabric used on wristbands = 339.48 inches
Total number of players = 36
Amount of fabric used for each one = Total fabric used for headbands divided by Total number of players
Amount of fabric used for each one =

Answer:
the answer is c) 1.08
Step-by-step explanation:
Step1:
Formula for calculating z-score is;
Z= (x-mean)/standard deviation
where x is the value for which z-score is required
Step 2:
As asked in the question z-score for highest grade is required which is 91;
z= (91-81)/9.3
z=10/9.3
z=1.075
which is approximately;
z=1.08

To determine the perimeter of the pentagon, you must first calculate a side length of it. Let's name the coordinates A(-1,4) and B(2,3).
To figure out how far the points are from each other, you have to use the distance formula:
D_{AB}= \sqrt{(2--1)^2+{(3-4)^2}
Now, the formula for the perimeter of a pentagon is
P = 5×side length
So...
Perimeter = 5×
The answer is (2)
Answer:
5 square inches
Step-by-step explanation:
First, we need to find the area of one sticky note:
The formula is Lenth*Width
Area of one sticky note:
5/6*2/3=10/18
=5/9 square inches
Now, we find the area of 9 sticky notes:
5/9*9=5
5 square inches
Hope this helps! Have an amazing day!
