6^2 = x (x - 9)
x^2 - 9x - 36 = 0
(x -12)(x + 3) = 0
x - 12 = 0; x = 12
x +3 = 0; x = -3

so in this case x = 12 then DC = 12 - 9 = 3

y^2 = 12^2 - 6^2
y^2 = 144 - 36
y^2 = 108
y = 10.4

Paula walks 1/12 mile in 5/3 minutes. What rate is equivalent to the rate she walked?

mel-nik [20]

The rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute

<h3>Calculating Rate </h3>

From the question, we are to determine the rate which is equivalent to the rate Paula walked

Using the formula,

$Rate = \frac{Distance}{Time}$

From the given information,

Distance = 1/12 mile

Time = 5/3 minutes

Putting the parameters into the formula, we get

$Rate =\frac{\frac{1}{12} }{\frac{5}{3} }$

$Rate = \frac{1}{12} \div \frac{5}{3}$

$Rate = \frac{1}{12} \times \frac{3}{5}$

$Rate = \frac{3}{60}$

$Rate = \frac{1}{20}$ mile/minute

Hence, the rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute
