Think of a situation in the real world where a relationship occurs between two sets. For example, I could list several different

people and then list their birthdays. I could then form a relationship between these sets. First, illustrate the relationship using arrows. Then determine if the relationship is a function or not. State why?

Answer:

See Explanation

Step-by-step explanation:

Required

Determine if a real life situation is a function or not

I will give 2 instances

(1) Students and their ID

The relationship is as follows:

Student 1 -----> ID-1

Student 2 -----> ID-2

Student 3 -----> ID-3

Student 4 -----> ID-4

---------

----

--

Student n -----> ID-n

The above is a function because every student has a unique student ID.

In fact, the relation is a one-on-one function because no two students will have the same ID

(2) People and their year of birth

The relationship is as follows:

Person 1 -----> 2000

Person 2 -----> 2001

Person 3 -----> 2002

Person 4 -----> 2001

---------

----

Person n -----> 2005

The above is not a function because there is a possibility that a more than one person will have the same year of birth.

Answer:

1. Because a right angle is 90 degrees, the answer to this is 90 - 65 = 25.

2. This question is similar to the last one, but this time the angle is 180 degrees total, so the answer is 180 - 55 = 125.

3. I'm fairly certain the lines here indicate that all three angles are the same. If all three angles make 180 degrees, the answer would be 180 / 3 = 60.

4. This is the same as in question 2. 180 - 135 = 45.

5. Again, because all three angles need to make up 180 degrees, we can just simply do 180 - (65 + 45) = 70.

6. With a quadrilateral, the angles add up to 360 degrees. We can do the same thing as in question 5 here. 360 - (70 + 95 + 55) = 140.

7. I don't remember exactly how to solve this but 55 degrees is correct because 55 + 55 + 70 = 180 which is the only possible value.

I haven't done this kind of stuff in a looooong time so I hope this suffices! :)

C Betty rearranged the movies on her shelving unit after a few days. She placed equal numbers of movies on the bottom 3 shelves,
mixas84 [53]

There are total 53 movies on the shelving unit

Step-by-step explanation:

<u>DATA</u>

Equal movies on the bottom 3 shelves: 3x

10 movies on each of the top 2 shelves = 2*10 = 20

<u>Equation:</u>

3x + 20

<u>Question:</u>

Number of movies on the shelving unit if 11 movies are on each bottom 3 shelves: x = 11

<u>Solution:</u>

3x + 20

3(11) + 20 = 33 + 20 = 53

Therefore, there are total 53 movies on the shelving unit; 20 on the top 2 shelves and 33 on the bottom 3 shelves altogether.

Step 1: d+3 &lt; 1 <br><br> Step 2: b+6&lt; 9
In-s [12.5K]

Answer:

1) d < -2

2) b < 3

Step-by-step explanation:

1) d+3< 1

subtract both sides by 3

d+3 -3 < 1-3

d<-2

2) b+6< 9

subtract both sides by 6

b+6 -6 < 9 -6

b< 3
