Answer:

36 centimeters in the poster

Step-by-step explanation:

Let us plan out our steps, and solve for each:

1. Given the information, let us create a proportionality as such:

3 = 1 ⇒ x - centimeters in the poster

x 12

2. Now let us cross multiply, and solve through simple algebra for x:

3 * 12 = x,

x = 36 centimeters in the poster

It takes Wayne 1/10 hours to walk 2/6 mile park loop. What is Wayne's unit rate, in miles per hour?

-BARSIC- [3]

If it takes .1 hours to walk 2/6 miles, then it takes one hour to walk 20/6 miles.
20/6 miles = 3.33 miles
So that is 3.33 miles per hour.

Answer:

$2{x}^{ \frac{3}{2} }$

Step-by-step explanation:

We want to simplify:

$\frac{ {x}^{2} + {x}^{2} }{ {x}^{ \frac{1}{2} } }$

We first simplify the numerator to obtain:

$\frac{ 2{x}^{2} }{ {x}^{ \frac{1}{2} } }$

Next the quotient rule:

$\frac{ {a}^{m} }{ {a}^{n} } = {a}^{m - n}$

We apply this quotient rule to get:

$\frac{ 2{x}^{2} }{ {x}^{ \frac{1}{2} } } = 2{x}^{2 - \frac{1}{2} }$

Simplify exponents:

$\frac{ 2{x}^{2} }{ {x}^{ \frac{1}{2} } } = 2{x}^{ \frac{3}{2} }$

Therefore the given expresion simplifies to:

$2{x}^{ \frac{3}{2} }$
