The ratio of Ds to As in the school was 4 to 72. If there were 1080 As in the school this term, how many Ds were there? 60
4
66
19,440

60 D's

Step-by-step explanation:

We are given that the ratio of D to A is 4 to 72,

We can write that as 4:72.

Since students got 1080 A's. we can divide 1080 by 72 to help us find the answer.

1080/72=15

We know that the relationship between the amount of D's simplified and the actual amount of D's is equal to 15 times. So we do the given amount (4) multiplied by 15 (4*15) to get 60.

Please let me know if you have any questions.

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.
