Speed of student A is 180 ft/min
Speed of student B is 120 ft/min
Relative speed=(120+180)=300 ft/min
Distance between them is 2420 ft
Time taken for them to meet will be:
time=distance/speed
=(2420-20)/300
=8 min
The line from the point to its reflection should be perpendicular.If we imagine a line from (5,7) to (2,2), it would have a slope of (2-7)/(2-5) = 5/3.
For that line to be perpendicular to y=-2/5x+6, their slopes should be each other's negative reciprocals.
-2/5 negative reciprocal is 5/2, which is not equal to our calculated 5/3, so (2,2) cannot be the reflected point. Evan was wrong.
Q1-74: AB have slope 6/5, C has -5/6, D 6/5, E -5/6 again.
Answer:
It is the one you selected
C
Step-by-step explanation:
To convert this into a fraction, you would have to move the "3" to the fraction. But the position of the "3" would ALWAYS be below the number which in this case would be "7" so it would be x ^ 7/3
plz brainliest :'D
1min: 100 ft
2min: 100(.5)= 50 ---> 100+50= 150 ft
3min: 50(.5)=25 ---> 150+25= 175 ft
4min: 25(.5)=12.5 ---> 175+12.5= 187.5 ft
5min: 12.5(.5)=6.25 ---> 187.5+6.25= 193.75ft
answer: 193.75 ft
