What decmal of an hour is a second​

0.000126. Hint:There are 60 seconds in a minute and 60 minutes in an hour. Therefore on multiplying all the values we get the number of seconds in an hour. Hence we can divide one second by the total number of seconds in an hour to get the desired decimal value.

Step-by-step explanation:

Please give me brainlist

1 hour has 3600 seconds

to get the decimal of of a second you divide 1 by 3600

you get 2.78× 10 ^ -4

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
