Pat wants to enter a typing contest. in order to enter, one has to be able to type 50 words per min. pat took 15 seconds to type 10 words. can she enter the contest.

Answer from: 902coo

Well, if a minute is 60 seconds, and she typed 10 words in 15 seconds, we can easily calculate the words per minute. Since 15 * 4 = 60, we need to do the same with 10. Ten * 4 = 40, so she cannot enter the typing contest. I hope this helps you.

Answer from: Quest

the system of inequalities is

$y> (1/3)x$

$y\leq-x+4$

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

$m=y/x=1/3$

the equation of the dashed line is

$y=(1/3)x$

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

$y> (1/3)x$

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

$m=(4-0)/(0-4)=-1$

the equation of the solid line is

$y=-x+4$

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

$y\leq-x+4$

step 3

the system of inequalities is

$y> (1/3)x$

$y\leq-x+4$
