Stop copying the question, it's confusing
so 100 cookies and 20 brownies
what is the greatest number you can divide them both by?
find the GCF
factor them
100=2*2*5*5
20=2*2*5
so the GCF is the common group to both or 2*2*5 or 20
100/20=5
20/20=1
there are 20 groups, each wit 5 cookies and 1 brownie
20 groups
Answer:
Option A.
Step-by-step explanation:
we know that
The area of a trapezoid is equal to
![A=(1/2)(b1+b2)h](https://tex.z-dn.net/?f=A%3D%281%2F2%29%28b1%2Bb2%29h)
we have
![b1=1\frac{1}{4}\ ft](https://tex.z-dn.net/?f=b1%3D1%5Cfrac%7B1%7D%7B4%7D%5C%20ft)
![b2=14\ in](https://tex.z-dn.net/?f=b2%3D14%5C%20in)
![h=3\ in](https://tex.z-dn.net/?f=h%3D3%5C%20in)
Convert feet to inches first
Remember that
![1\ ft=12\ in](https://tex.z-dn.net/?f=1%5C%20ft%3D12%5C%20in)
so
![1\frac{1}{4}\ ft=\frac{5}{4}\ ft=12*\frac{5}{4}=15\ in](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B4%7D%5C%20ft%3D%5Cfrac%7B5%7D%7B4%7D%5C%20ft%3D12%2A%5Cfrac%7B5%7D%7B4%7D%3D15%5C%20in)
substitute in the formula
I think you’re right as if the less than was the other way I would shade the top
