What is the surface area of this wedge ?

84 ft^2  

Step-by-step explanation:

The whole prism can be divided into  5 surfaces.

Two triangles and 3 rectangles.

 Find the area of each of the 5 shapes and add them together.

The triangle has a  base of 4 and a height of  3.

Area of triangle 1:    A= 4*3 * 1/2  

                               A = 6  

Area of triangle 2:     A = 4*3 * 1/2

                                   A = 6

Area of rectangle 1 :   A= 4*6

                                    A = 24

Area of rectangle 2;   A = 3*6  

                                     A = 18

Area of rectangle 3:    A= 5 *6  

                                      A = 30

Now add the areas together

    6 + 6 + 24 + 18 + 30 + =  84 ft^2

84

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.

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
