Answer:

9 ft

Step-by-step explanation:

The Pythagorean theorem states

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

Substituting in what we know (one leg is 12 and the hypotenuse is 15)

12^2 +b^2 = 15^2

144+ b^2 = 225

Subtract 144 from each side

144-144 +b^2 = 225-144

b^2 =81

Take the square root of each side

sqrt(b^2) = sqrt(81)

b = 9

Health club a charges 100.00 membership fee plus 25.00 per plus 25.00 per month
Snowcat [4.5K]

Answer:

Month 5 the cost will be the same

Step-by-step explanation:

Make to equations from the given information

Let y be the cost, and let x be the number of months

Club A:  y = 25x + 100

Club B:  y = 20x + 200

It wants to know when the cost will be the same, so set the 2 equations equal to each other and solve..

25x + 100 = 20x + 200

5x = 100              (subtract 20x and 100 from both sides)

  x = 20                (divide both sides by 5)

So after 5 months the cost will be equal,
