The answer is 35. To find it, put the numbers in chronological order, the split the set in half. Find the middle of the first half, which is 49. Then, find the middle of the second half, which is 84. Lastly, subtract 49 from 84 to get 35! Hope that helps!

Answer:

FALSE, (2, 9) is not a solution to the set of inequalities given.

Step-by-step explanation:

Simply replace x by 2 and y by 9 in the inequalities and see if the inequality is true or not:

irst inequality:

$y\geq 4x\\9\geq 4\,(2)\\9\geq 8$

so thi inequality is verified as true since 9 is larger or equal than 8

Now the second inequality:

$y$

This is FALSE since 9 is larger than 4 (not smaller)

Therefore the answer to the question is FALSE, (2, 9) is not a solution to the set of inequalities given.

Step-by-step explanation:

formula for cone = $\frac{1}{3}$ *π* $r^{2}$ *h

they tell us that the diameter is 8 so r = 4
