Mathematics

Answer: \sqrt{66}

Step-by-step explanation:

The Pythagorean Theorem says that a^2 + b^2 = c^2  where a and b are the two legs.  

In this care leg 1 is 4 and leg two is the square root of 50. So we will square them to find c which is the hypotenuse.

4^2 + \sqrt{50} ^2  = C^2

16 +  50 = c^2

  66 = c^2

    c =\sqrt{66}

marshall27 [118]

Answer:

x=-2 y=-6

Step-by-step explanation:

subtract x from both sides

-4=3x+2

subtract 2 from both sides

-6=3x

divide by 3 on both sides

x=-2

y=-2-4=-6

y=4(-2)+2=-8+2=-6

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.
