Answers are below
Step-by-step explanation:
10a) Find how many multiples of 3 there are 4/12 = 1/3
10b) Find how many factors of 12 there are 6/12 = 1/2
10c) Find how many prime numbers there are 5/12
10d) 3/12 = 1/4
10e) Find how many numbers are less than 12 11/12
8.8 million is the right answer
The area of a rhombus is 1/2 times the lengths of the diagonals
A = (1/2)(AC)(BD)
Since the diagonals bisect each other, and ed = 8, BD must be 16. Substituting in this for BD and the given area (168) we get the following:
168 = (1/2)(AC)16
168 = 8(AC)
21 = AC
A. A=1/2(6x8)= 24
B=6+15+10=31
SA=2(24)+31(8)=296in.
b.V=1/2(8)(6)(15)=360in.
c. I'm not sure.
