A. The change after 1 hour is 2 inches because 6x10=60 (minutes) and you multiply 1/3 by 6/1 and get 6/3 or 2 inches.

b. The change after 2.25 hours is 4 1/2 inches because 2x2=4 and .25 (1/4) of an hour is 15 minutes so take 1/3 and multiply it by 1/2 (half of 10 is 5 and 10+5=15 min.) and you get 1/6 and then you add 1/3 and 1/6 together to get 1/2. So together it is 4 1/2 inches.

An electrician sent Bonnie an invoice in the amount of 'a' dollars for 6 hours of work that was done on Saturday. The electricia
Mazyrski [523]

Answer:

(a-f)/6 = r

Step-by-step explanation:

The total Bonnie must pay is the weekend fee plus the hourly rate times the hours worked

Cost = weekend fee * hourly rate* hours

hours = 6

weekend fee =f

hourly rate = r

Cost = a dollars

Substituting in what we know

a = f+ 6r

We want to solve for r

Subtract f from each side

a-f =f-f +6r

a-f = 6r

Divide each side by 6

(a-f)/6 = 6r/6

(a-f)/6 = r

Simplify. x-2/(x^2+4x-12)
balandron [24]
Simplifying the above expression we shall proceed as follows:
<span>x-2/(x^2+4x-12)
factoring out the denominator we get:
</span>x^2+4x-12
=x^2-2x+6x-12
=x(x-2)+6(x-2)
=(x+6)(x-2)
thus our expression will be:
(x-2)/[(x+6)(x-2)]
simplifying the above we get:
1/(x+6)

Answer: 1/(x+6)
