The volume of the box when it's filled to 3 inches deep is 12×8×3 = 288 in³
The box is filled up to 1.5 inches from the top, that means the box is filled only
3-1.5 = 1.5 inches deep
The volume of the box when it's filled to 1.5 inches deep is 12×8×1.5 = 144 in³
The number of flours saved is 288 - 144 = 144 in³
Answer:
50
Step-by-step explanation:
cos (2x) = cos x
2 cos^2 x -1 = cos x using the double angle formula
2 cos ^2 x -cos x -1 =0
factor
(2 cos x+1) ( cos x -1) = 0
using the zero product property
2 cos x+1 =0 cos x -1 =0
2 cos x = -1 cos x =1
cos x = -1/2 cos x=1
taking the arccos of each side
arccos cos x = arccos (-1/2) arccos cos x = arccos 1
x = 120 degrees x=-120 degrees x=0
remember you get 2 values ( 2nd and 3rd quadrant)
these are the principal values
now we need to add 360
x = 120+ 360n x=-120+ 360n x = 0 + 360n where n is an integer
Answer:
How is the behavior of food coloring in the cool and heated water different? ... The food coloring in cool water remained at the bottom of the container. ... the food coloring was caused by the movement of heat through the water and the formation of convection currents. The warmer water is less dense, so it rises to the surface.
