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=

total of apples - take away four

6-4 = 2

answer is 2 apples

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
