Answer:
The fourth pair of statement is true.
9∈A, and 9∈B.
Step-by-step explanation:
Given that,
U={x| x is real number}
A={x| x∈ U and x+2>10}
B={x| x∈ U and 2x>10}
If 5∈ A, Then it will be satisfies x+2>10 , but 5+2<10.
Similarly, If 5∈ B, Then it will be satisfies 2x>10 , but 2.5=10.
So, 5∉A, and 5∉B.
If 6∈ A, Then it will be satisfies x+2>10 , but 6+2<10.
Similarly, If 6∈ B, Then it will be satisfies 2x>10 , and 2.6=12>10.
So, 6∉A, and 6∈B.
If 8∈ A, Then it will be satisfies x+2>10 , but 8+2=10.
Similarly, If 8∈ B, Then it will be satisfies 2x>10. 2.8=16>10.
So, 8∉A, and 8∈B.
If 9∈ A, Then it will be satisfies x+2>10 , but 9+2=11>10.
Similarly, If 9∈ B, Then it will be satisfies 2x>10. 2.9=18>10.
So, 9∈A, and 9∈B.
The company should produce "85" DVD's to maximize the profit.
According to the question,
The profit P for producing n DVD copies are
Let,
- The number of units be "n".
Now,
To find the minimize profit,
→ 
→ 
By substracting "3.4" from both the sides, we get
→ 
→ 
→ 
→ 
Thus the answer above is right.

Answer:
q-22=24. Hope this helps.
Step-by-step explanation:
22 less than a number, meaning 22 is subtracted FROM an unknown variable. Going by this you would add 22 on both sides, giving you an answer of 46.
57/100 in a decimal notation would be 0.057.Sinse here is no whole number,we put p and a decimal(0.),then,here is 0 in tenth place,because we cant put anything there sinse our fraction starts with hungreths,so we put 0.057 Hope it helped
