Karen plans to drive to a national park that is 582.8 miles away her car gets 23.5 miles on 1 gallon of gasoline gasoline cost $
NARA [144]

Answer: The correct answer is $85.56

Step-by-step explanation:

If Karen gets 23.5 miles per one gallon of gas, we divide 582.8 miles by 23.5 to see how many gallons she will use to go the 582.8 miles. The answer is 24.8 gallons. (582.8/23.5=24.8)

We then multiply 24.8 ( the total amount of gallons) x $3.45 (per gallon)= $85.56 for the entire trip

What is the slope of a line perpendicular to the line whose equation is 5x - y = -7.
BARSIC [14]

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

5x-y=-7\implies 5x-y+7=0 \\\\\\ \stackrel{\stackrel{m}{\downarrow }}{5} x+7=y\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}

so a line perpendicular to that one above will have a slope of

\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{5\implies \cfrac{5}{1}} ~\hfill \stackrel{reciprocal}{\cfrac{1}{5}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{1}{5}}}

Kendra has $ 9.90 in dimes and quarters. If she has 4 times as many quarters as dimes, how many of each coin does she have?
KatRina [158]
Since it is 4 times as many quarters and dimes, you can use a chart for guess and check. I started with 8 dimes and 32 quarters.

If you keep going, you end up with the fact that there are 36 quarters and 9 dimes.
