People use water to​ cook, clean, and drink every day. An estimate of 27.4​% of the water used each day is for drinking. If a family uses 68.5 gallons of water a day for drinking​, how many gallons do they use every​ day?

The common definition of a 3-day supply is 3 gallons per person—a gallon per person, per day—half to drink and a half to use for cooking and sanitation. The Centers for Disease Control and Prevention (CDC) even recommends drinking your half-gallon every day during an emergency, no matter what.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
