Answer:

(x +4)^2 + (y-2)^2 = 16

Step-by-step explanation:

We can write the equation for a circle with the formula

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

Where (h,k) is the center and r is the radius

We know the center is at (-4,2) and the radius is 4

(x- -4)^2 + (y-2)^2 = 4^2

(x +4)^2 + (y-2)^2 = 16

Ariana bought 5 dozen pears at $36 per dozen . She discovered that 7 were rotten and she sold the rest at $4.50 each . Calculate

GrogVix [38]

Step-by-step explanation:

1 dozen = 12 pears

12 pears = $36

1 pear = 36/12 = $3

Total Cost of Pears = No. of pears x price of 1 pear

= (5x12) x 3

= 60 x 3

= $180

Sale of Pears = Price per pear x (Total Pears bought - Rotten Pears)

= $4.50 x (5x12-7)

= $4.50 x 53

= $238.50

Profit/Loss = Sale of Pears - Total Cost of Pears

= $238.50 - $180

= $58.50

Ariana made a profit of $58.50.

Help? 11 3/4 is the quotient of a number y and 6 1/4

LUCKY_DIMON [66]

Answer:

y divided by 6 1/4 = 11 3/4

Step-by-step explanation:

First, change the mixed numbers into improper fractions:

y divided by 25/4 = 47/4

Next, multiply both sides by 25/4:

y divided by 25/4 x 25/4 = 47/4 x 25/4

The 25/4's on the left side of the equation cancel each other out, leaving you with:

y = 47/4 x 25/4

Multiply 47 x 25 and keep the same denominator:

y = 1,175/4

Divide and:

y = 293 3/4
