Step-by-step explanation:
Kayla can make 50 ribbons for the show using 32 feet ribbon
<u>Solution:</u>
Given, Kayla's making ribbons for school spirit day a roll of ribbon is 32 ft long And for each individual ribbon she needs 0.64 ft
We have to find how many ribbons can she make for her old show.
Number of ribbons that can be made is found out by dividing total available ribbon by ribbon length required for single ribbon
![\text { number of ribbons can be made }=\frac{\text { total available ribbon length. }}{\text { ribbon length required for single ribbon }}](https://tex.z-dn.net/?f=%5Ctext%20%7B%20number%20of%20ribbons%20can%20be%20made%20%7D%3D%5Cfrac%7B%5Ctext%20%7B%20total%20available%20ribbon%20length.%20%7D%7D%7B%5Ctext%20%7B%20ribbon%20length%20required%20for%20single%20ribbon%20%7D%7D)
![\begin{array}{l}{=\frac{\text { total } 32 \text { feet }}{0.64 \text { for each ribbon }}} \\\\ {=\frac{32}{0.64}} \\\\ {=50 \text { ribbons }}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%3D%5Cfrac%7B%5Ctext%20%7B%20total%20%7D%2032%20%5Ctext%20%7B%20feet%20%7D%7D%7B0.64%20%5Ctext%20%7B%20for%20each%20ribbon%20%7D%7D%7D%20%5C%5C%5C%5C%20%7B%3D%5Cfrac%7B32%7D%7B0.64%7D%7D%20%5C%5C%5C%5C%20%7B%3D50%20%5Ctext%20%7B%20ribbons%20%7D%7D%5Cend%7Barray%7D)
Hence, Kayla can make 50 ribbons for the show using 32 feet ribbon.
Answer:
3 feet
Step-by-step explanation:
A cube has 6 square congruent faces, thus
area of 1 face =
= 9 ft²
The area of a square = s² ← s is the length of a side, hence
s² = 9 ( take the square root of both sides )
s =
= 3
X²-10x+15=0
x²-10x=0-15
x²-10x=-15
x(x-10)=-15
x=-15/(x-10)
Answer:
y = -8
Step-by-step explanation:
-7y + 11 = 75 + y
Bring the <em>"</em><em>y</em><em>"</em><em> </em>variable on one side, and rest on the other.
Rearranging, we get,
-7y - y = 75 - 11
-8y = 64
-y = 8
y = -8
