In how many arrangements can a teacher seat 3 girls and 3 boys in a row of 6 seats if the boys are to have the first, third, and fifth seats?

36 ways.

Step-by-step explanation:

There are  3 seats available to the 3 girls.

So we need to find the number of ways  we can arrange 3 girls.

This is 3!  which works out to 3*2*1 = 6 ways.

Now the 3 boys can also be arranged in 6 ways in their 3 seats.

So the total number of arrangements are 6*6 = 36.

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
