Answer:

Option D is the correct option
Step-by-step explanation:
Let the sets be A and B.
A = { 1 , 2 , 3 , 4 , 5 }
B = { 2 , 4 , 6 , 8 , 10 }
<u>Finding </u><u>A</u><u> </u><u>union</u><u> </u><u>B</u><u> </u><u>(</u><u> </u><u>A</u><u> </u><u>∪</u><u> </u><u>B</u><u> </u><u>)</u>
<u>The</u><u> </u><u>union</u><u> </u><u>of </u><u>sets</u><u> </u><u>A</u><u> </u><u>and</u><u> </u><u>B</u><u> </u><u>is </u><u>the </u><u>set </u><u>of </u><u>all</u><u> </u><u>elements</u><u> </u><u>which</u><u> </u><u>belongs</u><u> </u><u>either</u><u> </u><u>A</u><u> </u><u>or </u><u>B</u><u> </u><u>or</u><u> </u><u>both</u><u> </u><u>A</u><u> </u><u>and</u><u> </u><u>B</u>
So, list them :
A ∪ B = { 1 , 2 , 3 , 4 , 5 , 6 , 8 , 10 }

7+8+9=24.. So 9 is the greatest..
It’ll take 7 days for both tanks to have the same amount of water.
Day 1
108 - 5 = 103
45 + 4 = 49
Day 2
103 - 5 = 98
49 + 4 = 53
Day 3
98 - 5 = 93
53 + 4 = 57
Day 4
93 - 5 = 88
57 + 4 = 61
Day 5
88 - 5 = 83
61 + 4 = 65
Day 6
83 - 5 = 78
65 + 4 = 69
Day 7
78 - 5 = 73
69 + 4 = 73
Answer:
you need a clearer picture.
Step-by-step explanation:
Using Heron's formula, 9=6+6+6/2
A=(sqrt)9(9-6)(9-6)(9-6)
A=9(sqrt)3
A=roughly 15.8845 square units
