Mason is cutting wood for a carpentry project his bossis completing. he has been given boards which are 72 inches long, but he needs them to be 20 percent of this size. how long should the boards be cut to? (he can only measure in fractions of an inch)

Answer

Find the  how long should the boards be cut to .

To proof

as given

He has been given boards which are 72 inches long,

but he needs them to be 20 percent of this size.

20 % is written in the decimal form

= 0.20

20 % of the  72 inches long

=0.20× 72

= 14.4 inches

let us assume that x be the boards be cut to get the 20 percent of the  72 inches long board.

Now find out  how long should the boards be cut to.

72 - x = 14.4

x = 72 - 14.4

x = 57.6 inches

Mason cuts 57.6 inches to get  20 percent of the  72 inches long board.

Hence proved

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.
