Tom has a water tank that holds 5 gallons of water.Tom uses water from a full tank to fill 6 bottles that each hold 16 ounces and a pitcher that holds 1/2 gallon.How many ounces of water are left in the water tank?

Answers

Answer:

503.525 gallon ( approx )

Step-by-step explanation:

Given,

Water hold by of the water tank = 5 gallon

We know that, 1 gallon = 133.228 ounces

⇒ Water hold by of tank in ounces = 5 × 133.228 = 666.139 ounces,

Here, it is given that, 6 bottles that each hold 16 ounces and a pitcher that holds 1/2 gallon is used from tank,

Since, the quantity of water hold by6 bottle in which each hold 16 ounces = 6 × 16 = 96 ounces,

Also, 1/2 gallon = 1/2 × 1 gallon = 1/2 × 133.228 = 66.614 ounces

Thus, the total consumed water = 96 + 66.614 = 162.614 gallon

Hence, the quantity of water left in the tank = Water hold by of tank in ounces - the total consumed water

= 666.139 - 162.614

= 503.525 gallon
1 gallon is 128 ounces, 5 gallons is 640 ounces. So 6*16=94 ounces Pitcher equals 64 ounces, so 640-158=452, there are 452 ounces of water left

Answer:

\large\boxed{r^2=(x+5)^2+(y-4)^2}

Step-by-step explanation:

The equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have diameter endpoints.

Half the length of the diameter is the length of the radius.

The center of the diameter is the center of the circle.

The formula of a distance between two points:

d=√((x_2-x_1)^2+(y_2-y_1)^2)

Substitute the coordinates of the given points (-8, 2) and (-2, 6):

d=√((6-2)^2+(-2-(-8))^2)=√(4^2+6^2)=√(16+36)=√(52)

The radius:

r=(d)/(2)\to r=(√(52))/(2)

The formula of a midpoint:

\left((x_1+x_2)/(2),\ (y_1+y_2)/(2)\right)

Substitute:

x=(-8+(-2))/(2)=(-10)/(2)=-5\n\ny=(2+6)/(2)=(8)/(2)=4

(-5,\ 4)\to h=-5,\ k=4

Finally:

(x-(-5))^2+(y-4)^2=\left((√(52))/(2)\right)^2\n\n(x+5)^2+(y-4)^2=(52)/(4)\n\n(x+5)^2+(y-4)^2=13
