Each month, you get your water bill in the mail. You know that each month you are charged a service

Answer:

$0.004 per gallon

Step-by-step explanation:

Given:

Service Fee= $22

Fixed rate per gallon= m

Water Consumed= 2256 gallons

Total bill charged= $31.02

Now by computing the equation we get

$\textrm{Total bill charged} = \textrm{Service fee} + (\textrm{fixed charge per gallon} \times \textrm{water consumed})$

Substituting data we get

$22+m2256=31.02$

$m2256= 31.02-22$

$m2256=9.02$

$\therefore m =\frac{9.02}{2256} =0.00399$

Rounding off above value we get

$m=0.004$ per gallon

Answer:

Step-by-step explanation:

As long as the indices are the same for all the radicals, you can multiply them together. Our index for each of these is 2 (square root) so we multiply them all together and put it under 1 square root sign (radical):

$\sqrt{150x^6$ The largest perfect square in 150 is 25, and the 6th power on the x needs just to be rewritten in terms of an exponent of 2 to give us:
