For this case we can solve the problem, applying the following rule of three:

1 pound ---------------> $ 3.09

4.5 pounds -----------> x

From here, we clear the value of x.

We have then:

x = (\frac{4.5}{1}) (3.09)

x = (4.5) (3.09)

x = 13.905

To the nearest hundredth

x = 13.91

Answer:

The cost of 4.5 pounds of beef equals $ 13.91.

Since 1 pound is $3.09, 4.5 pounds will be:

4.5*3.09=13.905

It says to round to nearest hundredth, so your answer is $13.91.

Find the center and radius of the circle represented by the equation below.
valina [46]

Answer:

radius 4

center (3,6)

Step-by-step explanation:

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

coordinates of the center (h, k) and the radius is (r)

x² + y²- 6x - 12y +29=0

x² - 6x + y²- 12y +29=0

(x² - 6x) + (y²- 12y) +29=0

complete the square

(x² - 6x) + 9 + (y²- 12y) +36 +29=  + 9  +36

(x² - 6x + 9) + (y²- 12y + 36) = + 9  +36 -29

(x-3)^2 + (y-6)^2 = 16

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

coordinates of the center (h, k) and the radius is (r)

center (3,6)

radius 4
