Answer:
D. 15×4/100×4 = 60/400
Step-by-step explanation:
First I figured out how many photos there are in total, which was by doing 60/.15, since only 15% of the total photos are in black and white. We can already cross out all possibilities that don't have the denominator 400, but we can go a step further by seeing which one is 60/400, or equal to 60/400, which is D. 15×4/100×4 = 60/400.
<u>Given</u>:
Let X and Y be two sets.
The two sets are given by 
and 
We need to determine the value of the set 
<u>Value of the set </u><u>:</u>
The value of the set is the set that contains all the elements that are at least in one of the two sets.
Hence, the union of the set is given by
Arranging in ascending order, we get;
Thus, the union of the sets X and Y is
C: pie
is a irrational number!
Ava's mother is 36, A+3A+2(3A)=120. 12+36+72=120. A=12. The smallest number is 12.5, X+(X+4)+2x=54. 12.5+16.5+25=54 :)
