Answer:60%
Step-by-step explanation:
If there are 1000 students in total and 600 are majoring in engineering, you divide 600 by 1000 to find the percent of students majoring in engineering. (600/1000) =.6
To turn a decimal into a percent you move the decimal over 2 places making it 60%.

Step-by-step explanation:
1/8 +(-3/16) = -1/16
Answer:
line f has a slope of -7/4
Step-by-step explanation:
parallel line always have opposite slopes
Answer:
Step-by-step explanation:
slope of line through (6,-1) and (11,2) = (-1 - 2)/(6 - 11) = 3/5
slope of line through (5,-7) and (8,-2) = (-7 - (-2))/(8 - 5) = -5/3
product of the slopes = -1, so the lines are perpendicular.
