One sample cup will hold 11.51 ounces of fluid.
Step-by-step explanation:
Diameter of cone shaped cup = 4 inches
Radius = 
Height of cup = 5 inches
Volume of cone = 
Putting values
Volume of cone = 
Volume of cone = 
Volume of cone = 20.93 inches cubed
Amount of fluid in one cubic inch = 0.55 ounces
Amount of fluid in 20.93 cubic inches = 0.55*20.93 = 11.51 ounces
One sample cup will hold 11.51 ounces of fluid.
6w^2 - 21w + 10w - 35
3w( 2w - 7) + 5 ( 2w - 7)
(3w + 5) ( 2w - 7)
This is the factorised form.
