What is the solution set of {x | x < -5} ∩ {x | x > 5}
Kisachek [45]

Answer:

The answer is: {x | x < -5} ∩ {x | x > 5}= { }.

Step-by-step explanation:

Let us first list the elements of the first set.

{x | x < -5} reads x is an element such that x is less than -5. So we list all the integers less than -5.

{x | x < -5}= {-6,-7,-8,-9,-10,-11,-12,-13,-14,...}

Similarly, we find the elements of the second set which reads: x is an element such that, x is greater than 5.  So we list all integers greater than 5

{x | x > 5}=  {6,7,8,9,10,11,12,13,14,...}

Finally we are required to find the numbers or elements in both sets that intersect or are the same with each other.

Since no element in both sets listed above intersect each other, the solution is an empty set:

Therefore, {x | x < -5} ∩ {x | x > 5}= { }.

Plsss help and thank u

Answer:

11/16

Step-by-step explanation:

There are 9 red crayons, 2 blue crayons, and 5 yellow crayons. We can represent this as a ratio of 9:2:5. Now we have to combine the red crayons and blue crayons so it's 11 red and blue crayons: 5 yellow crayons OR 11:5. Then we add those two values to find out the number of crayons there are, and there are 16. So out of 16 times, you will pick up a red or blue crayon 11 times. So this fraction is 11/16 which is already its simplest form.

Please help with geometry, you will get crown or smthin

Answer:

52√3 ft ²

Step-by-step explanation:

Formula for area of the trapezoid:

A=\frac{a+b}2h

a = Base = 11

b = Base = 15

h = Height = 4√3

Since the height is  4√3 we can turn it into a number:

4√3 = 6.92820323028 = 6.93

Now using the formula:

A=\frac{a+b}2h=\frac{11+15}2\times6.93=90.06664 =90.07

As you can see that it not a answer choice.

We can turn the answer choice into number:

44√3 ft ² = 76.21023553.. ≈ 76.20

44√3-24 ft ²=52.21023553.. ≈ 52.20

60√3 ft ² = 103.92304845.. ≈ 103.90

52√3 ft ² = 90.06664199.. ≈ 90.07

Thus, the answer is 52√3 ft ²
