Answer:

The answer to your question is It will take 1 hour to find Marissa

Step-by-step explanation:

Data

Marissa    time = 7:00 am      speed = 12 mi/h

Roommate  time = 7:30 am   speed = 18 mi/h

Process

1.- Calculate the distance traveled by Marissa in 30 min (0.5 h)

    d = vt

    d = (12)(0.5)

    d = 6 mi

2.- Write an equation to solve this problem

Distance  traveled by Marissa = Distance traveled by the roommate

                                       6 + vmt = vrt

- Substitution

                                       6 + 12t = 18t

- Solve for t

                                       6 = 18t - 12t

                                        6 = 6t

                                        t = 6/6

                                        t = 1 h

Which choice is equivalent to the quotient shown here when x is greater than or equal to 0?
Dima020 [189]

Answer: OPTION C

Step-by-step explanation:

Remember that:

\sqrt[n]{a^n}=a

And the Product of powers property establishes that:

a^m*a^n=a^{(mn)}

Rewrite the expression:

\frac{\sqrt{18x} }{\sqrt{32} }

Descompose 18 and 32 into their prime factors:

18=2*3*3=2*3^2\\32=2*2*2*2*2=2^5=2^4*2

Substitute into the expression, then:

\frac{\sqrt{(2*3^2)x} }{\sqrt{2^4*2} }

Finally,simplifying, you get:

\frac{3\sqrt{(2)x} }{2^2\sqrt{2} }=\frac{3\sqrt{2x}}{4\sqrt{2}}=\frac{(3)(\sqrt{x})(\sqrt{2})}{(4)(\sqrt{2})}= \frac{3\sqrt{x}}{4}
