Answer:
4.72
Step-by-step explanation:
In order to solve this problem you need to setup a proportion. A proportion is two equivalent ratios. The problem gives you the first ratio, 4 inch gear to 22 inch diameter.
Then you will cross multiply and end up with 22g = 104
For the final step, you will divide both sides by 22, in order to isolate the variable g.
g = 4.72
or in other words, the size of the gear for a bike with a 26 inch wheel, is 4.72 in.

Answer:
The area of new pumpkin patch is = 15 x² + 380 x + 2400
Step-by-step explanation:
Given as :
The length of rectangular patch = L = 40 meters
The width of rectangular patch = W = 60 meters
So, The area of rectangular patch = Length × Width
Or, = L × W
So , = 40 meters × 60 meters
Or, = 2400 meters²
Again The Width of new Patch = ( 40 + 3 x ) meter
And The Length of new Patch = ( 60 + 5 x ) meter
Or, = L × W
So , = ( 40 + 3 x ) meters × ( 60 + 5 x ) meters
Or, = 2400 + 200 x + 180 x + 15 x²
Or, = 15 x² + 380 x + 2400
Hence The area of new pumpkin patch is = 15 x² + 380 x + 2400 Answer
