It takes ken 80 seconds to complete a lap and hamid 60 seconds to complete a lap .they start at the same time how many laps will they have run till the next meet at the start line search instead for it takes ken 80 seconds to complete a lap and hamid 60 seconds to complete a lap .they start at the same time how many laps will they have run till they next meet at the start line

 Ken will run 3 laps and Hamid will run 4 laps till they next meet at the start line.

Step-by-step explanation:

Given: It t takes Ken 80 seconds to complete a lap and Hamid 60 seconds to complete a lap .

To find when they, meet we need to find the least common multiple of 80 and 60.

Since

Therefore, LCM(60,80)=

Thus they will meet after 240 seconds.

So the number of laps completed by Ken=

The number of laps completed by Hamid=

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

0.50 , 0.75
