Answer:
25 minutes
Step-by-step explanation:
Worker1 is filling up at a rate of 11 per minute while worker2 is filling up at a rate of 11+1 per minute. Since worker1 has 25 extra barrels and since worker2 makes one extra barrel per minute it will take exactly 25 minutes to match worker1's barrel count.
we know the mid point formula
(x ,y)=<u>x</u><u>1</u><u>+</u><u>x</u><u>2</u> , <u>y</u><u>1</u><u>+</u><u>y</u><u>2</u>
2 2
=<u>0</u><u>+</u><u>1</u><u>0</u> , <u>6</u><u>+</u><u>0</u>

=(5,3)
centre of circle(x, y)=(5,3)
Answer:
25.) Slope of AB = 5
Slope of CD = -1/5
Perpendicular
26.) Slope of EF = -3/5
Slope of GH = -3/5
Parallel
Step-by-step explanation:
Use this formula to find slope.
Parallel lines have the same slope
Perpendicular lines have the opposite reciprocal and sign
25.)
Plug in AB slope is 5
2 - 7/ 3 - 4 = -5/-1 = 5
Plug in for CD slope is -1/5
3 - 4/ 2 - -3 = -1/5 = -1/5
The lines AB and CD are perpendicular because they have opposite reciprocals and opposite signs.
26.)
Plug in EF slope is -3/5
1 - 4/ 3 - -2 = -3/5 = -3/5
Plug in GH slope is -3/5
-5 - -2/ 4 - -1 = -3/5 = -3/5
The lines EF and GH are parallel lines because they have the same slopes.
Hope this helps ya!
