Brenna is buying 4.25 feet of ribbon for $1.95 a foot. she determines the product of the two numbers to determine the actual cost of the length of ribbon. which expression will result in the best estimate for brenna to use to check her multiplication?

4.25 feet of ribbon cost around $ 8.29

Step-by-step explanation:

We are given the following information in the question:

Length of ribbon to be bought by Brenna = 4.25 feet

Cost of 1 foot of ribbon = $1.95

Total or actual cost of the ribbon =

Cost of ribbon to be purchased by Brenna =

Thus, to find the actual cost Brenna should use the product of total length of ribbon to be bought and the unit cost of the ribbon.

Hence, 4.25 feet of ribbon cost around $ 8.29

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.

depends on how many days you are talking about
