To solve this problem, we need to first find the dimensions of the side of the blue and purple squares.
We're given that the purple (smaller) square has a side length of x inches.
We are also given that the blue band has a width of 5 inches.
Since the blue band surrounds the purple square on both sides, the length of the blue square is x+2(5)=x+10 inches.
The net area of the band is therefore the difference of the area of the blue square and the purple square, namely take out the area of the purple square from the blue.
Therefore
Area of band

[recall



or 20(x+5) if you wish.
Answer:
40%
Step-by-step explanation:
sloution is 16/40 only this we can get answer
It would be 80% since it decreases 20% each year so 20*4 is 80 so it’s 80%
Answer:
5 inches
Step-by-step explanation:
A cone's volume can be found using the formula
. If the cone has a diameter of 3 inches then its radius is half r= 1.5 inches. Substitute r = 1.5 and V = 12 cubic inches.

This means the height of the cone is 5.10 inches or to the nearest inch 5 inches.
