Walmart sells to sizes of milk. One contains a half gallon of milk and costs $1.82.

aivan3 [116]

Answer:

Difference = $0.01

Step-by-step explanation:

Given that:

Cost of half gallon = $1.82

Cost of one gallon = $3.68

First we will convert gallons to ounces.

1 gallon = 128 ounces

half gallon = 64 ounces

Now,

we will find unit rate of both.

Unit rate of half gallon = $\frac{1.28}{64} = \$0.02$

Unit rate of one gallon = $\frac{3.68}{128} = \$0.03$

Difference= 0.03 - 0.02 = $0.01

Hence,

Difference = $0.01

What is the standard form of the equation of a circle that has its center at (-2, -3) and passes through the point (-2, 0)?

Vlada [557]

Answer:

A. $(x+2)^2 + (y+3)^2 = 9$

Step-by-step explanation:

Equation of a circle is

$(x-x_1)^2+(y-y_1)^2=r^2$ ------------- (1)

Here

$(x_1, y_1) = (-2, -3)$

Radius is distance from center to circumference

$r=\sqrt{(-2+2)^2+(-3-0)^2}$

$r=3$

Substituting values in equation (1)

$(x+2)^2 + (y+3)^2 = 9$
