Calculate the unit rate: write your answer as a decimal 1/2 mile in ever 1/3 hour

Alexandra [31]

Answer:

$unit \: rate = \frac{distance}{time}$

unit rate is similar to speed / velocity:

$unit \: rate = \frac{ (\frac{1}{2} )}{ (\frac{1}{3})} \\ \\ = \frac{1}{2} \div \frac{1}{3} \\ \\ = \frac{1}{2} \times \frac{3}{1} \\ \\ = > { \boxed{ \boxed{unit \: rate = \frac{3}{2} \: miles \: per \: hour}}}$

[unit rate must have units including per <time> ]

Answer: m∠QPR = 40

<h2>Step-by-step explanation:</h2>

Because PG is perpendicular to PS, it is safe to assume that angle QPS is 90 degrees.

(7x-9) + (4x +22) = 90

x = 7

Because we need to find the degrees of QPR, plug in the equation for that angle with the value of x we found.

7(7) - 9 = 40

m∠QPR = 40
