A container in the shape of a pyramid has a rectangular base with dimensions of 5 inches by 15 inches. The height of the rectangular pyramid is 12 inches. Marbles fill half the volume of the container. How many more cubic inches of marbles are needed to finish filling the container?Enter your answer in the box. { }in3

First you find the volume of the pyramid:

1. find the area of the base:

A= 15 x 5= 75

2. Multiply the Area of the rectangle by the height; h= 12 and si use the result by 3.

V= A x h /3 =. 75 x 12 = 900 /3

V= 300

3. If only 1/2 is filled, that means

V= 300/2= 150 in3 is filled and

150 in3 of marbles is needed to fill the container.

150

Step-by-step explanation:

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
