Um, 150000? Don't write this inmetily because it may be wrong.
The best answer for this question would be:
D. 32
In order to get this, you have to get the sum in the line,
which is the first four people. So the solution would be: 4(23) = 92
For getting the sum of the people in the last 3 would be:
3(34) = 102
Next is the sum of everyone which the solution would be:
6(27) = 162
So the initial solution that we have now would be: F + 92 -
F + 102- F = 162
- F + 194 = 162
- F = 162 - 194
- F = - 32
The (F) here or the fourth person’s age would be= -32 / - 1
or 32
The given set is {-1,0,1,2,3,4,5}
(notice the -2 and 6 are excluded)
the subset which contain positive factors of 5 is {1,5}
so the complement set would be
{-1,0,2,3,4) which matches with b)
The answer is B, because 44 is greater than 42. I hope this helps!
This problem can be modeled by the picture shown below. We notice that we are given to side lengths, specifically legs, of the triangle. Therefore, we can use the Pythagorean Theorem, which states that a^2+b^2=c^2, where a and b are legs and c is the hypotenuse. So we can do:
16^2+12^2=c^2
256+144=c^2
400=c^2
The square root of 400 is
20, which is our hypotenuse.
(You might wonder why we used 12, that is because the whole base length is 24, but we only need half of the base to use the Pythagorean Theorem. 24/2 is 12).
