Answer to problem 13 is the set {2, 4, 5, 6, 7, 8, 10}
Answer to problem 17 is the empty set { } (see explanation below)
-----------------------------------------------
-----------------------------------------------
Explanation to problem 11
Set A = {1, 3, 4}
Set C = {2, 5, 7, 10}
When we union these two sets together, we simply combine them writing all of the elements in one big set. This is why the answer is {1, 2, 3, 4, 5, 7, 10}
-----------------------------------------------
Explanation to problem 13
B = {x|x is an even whole number less than 9}
B = {2, 4, 6, 8}
C = {2, 5, 7, 10}
Union B and C together and we get {2, 4, 5, 6, 7, 8, 10}
Toss out any duplicates
-----------------------------------------------
Explanation to problem 17
The previous problems had us doing set unions. This time we're doing set intersections. We have these two sets
A = {1, 3, 4}
C = {2, 5, 7, 10}
The question is: what number is in BOTH set A and set C? The answer is "there is no such value"
1 is in A, but not in C
3 is in A, but not in C
4 is in A, but not in C
2 is in C, but not in A
5 is in C, but not in A
7 is in C, but not in A
10 is in C, but not in A
There are no overlapping values. No values are shared between the two sets
So the answer is simply "the empty set" which can be written as { }. This is a pair of curly brace with nothing inside them. Your book may use the special symbol [tex]\varnothing[/tex], which is another way of saying "empty set"
The union of sets A and C (A U C) includes all unique elements from both sets resulting in {1, 3, 4, 2, 5, 7, 10}. The union of sets B and C (B U C) combines all unique elements from the even numbers less than 9 and set C, resulting in {2, 4, 6, 8, 5, 7, 10}. The intersection of sets A and C (A n C) is the empty set since they share no common elements.
When combining or intersecting sets, we are looking at the members that belong to each set.
The union of sets A and C (A U C) includes all elements that are in A, C, or both. So, A U C = {1, 3, 4, 2, 5, 7, 10}.The union of sets B and C (B U C) needs to take into account that set B contains all even whole numbers less than 9. So, first we list those numbers to define B as {2, 4, 6, 8}. Now, combining B and C, we have B U C = {2, 4, 6, 8, 5, 7, 10}.The intersection of sets A and C (A n C) contains all elements that are present in both sets. Since there are no common elements between A and C, A n C = {} , which is also known as the empty set.72 is 48% of what number
Answers
= 18/1 x 48/25
= 864/25
= 34 14/25
The number for which 72 is 48 percent of is approximately equal to 150.
To find the number that corresponds to 72 being 48% of it, set up an equation.
Let "x" represent the unknown number.
The equation for "72 is 48% of x" can be written as:
72 = 0.48 × x
To solve for "x," divide both sides of the equation by 0.48:
x = 72 / 0.48
x ≈ 150
Therefore, 72 is 48 percent of approximately 150.

At 9 am a car (A) began journey from a point, traveling at 40 mph. At 10 am another car (B) started traveling from the same point at 60 mph in the same direction as car (A). At what time will car B pass car A?
Answers
speed = distance/time
distance = speed * time
Car A travels t time.
Since car B starts an hour later, car B travels t - 1 time.
Car A:
d = st
s = 40t
Car B:
d = st
d = 60(t - 1)
The distance are equal, so
40t = 60(t - 1)
40t = 60t - 60
-20t = -60
t = 3
Car A started at 9 am.

Nick is making a model of a car to show at his school. The circumference of each wheel is 9.42 inches. What is the diameter of the wheel?
Answers
9.42 = 2 × 22/7 × r
9.42 ×7 / 22 ×2 = r
r = 1.5 inches
Diameter = 2r
= 2× 1.5 =3
Therefore, diameter = 3 inches
The diameter of the wheel can be found using the formula d = C / π. Given the circumference of 9.42 inches, the diameter is approximately 3 inches.
Step by Step Solution:
To find the diameter of the wheel, we can use the relationship between the circumference and the diameter of a circle. The formula is:
Circumference (C) = π × Diameter (d)
In this case, the circumference (C) is given as 9.42 inches. We need to solve for the diameter (d).
Re-arranging the formula to solve for diameter:
Diameter (d) = Circumference (C) / π
We can use the value of π (pi) which is approximately 3.14.
Given: Circumference (C) = 9.42 inches
π ≈ 3.14
Now, substitute the values into the formula:
d = 9.42 / 3.14 ≈ 3 inches
Therefore, the diameter of each wheel is approximately 3 inches.

Byun walked 15 blocks in 25 minutes. What was his average speed?
average = distance / time
Answers
Answer:
3/5 blocks per minute
Step-by-step explanation:
Byun walked 15 blocks in 25 minutes.
average = distance / time
Average speed is equal to distanced traveled by the time taken
[tex]Average =\frac{distance}{time}[/tex]
Distance = 15 blocks
and time = 25 minutes
So [tex]Average =\frac{15}{25}[/tex]
Divide both sides by 5
[tex]Average =\frac{15}{25}=\frac{3}{5}[/tex]
Average speed is 3/5 blocks per minute
