Which of the following numbers is 90 divisible by? 2,3,4,5,6,9,10

2,3,5,6,9,10

Step-by-step explanation:

To do this, we can look at how each value divides into 90. If it produces a whole number, they will be consider to be divisible

This means 4 is the only value that is not divisible into 90

2, 3, 5, 6, 9, 10

Step-by-step explanation:

We are to determine which numbers is 90 divisible by:

For this, we can use the divisibility rule which helps us find out whether a number is exactly divisible by other numbers (i.e. there is no remainder left).

Divisible by 2:

90 is divisible by 2 since it ends with a 0.

Divisible by 3:

90 is divisible by 3 because 90 is a multiple pf 3.

Divisible by 4:

90 is not divisible by 4 because the last two digits are not a multiple of 4

or the last two digits are not 00.

Divisible by 5:

90 is divisible by 5 since it ends with a 0.

Divisible by 6:

90 is divisible by 6 because it is divisible by 3.

Divisible by 9:

90 is divisible by 9 because it is a multiple of 9.

Divisible by 10:

90 is divisible by 10 since the last digit is 0.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
