Answer:
The graphical representation of the intervals as well as the solutions of the operation on the number line can be found in the attachment.
A ∪ B = (0, 6) ∪ (12, 24)
C ∩ D = (0, 6) ∩ (14, 24)
Question:
To control the pandemic, people have been restricted from leaving their homes. This measure is called quarantine and is one of the main ways to decrease the number of infections. The exit restrictions that have been taken are the following: o
• A: In Guayaquil, the first week you could not leave home from 12:00 to 6:00.
• B: In the rest of the country, the first week you could not leave home from 8:00 p.m. to 6:00 a.m.
• C: In the whole country, from the third week onwards you cannot leave the house from 2:00 pm to 6:00 am.
• D: If the cases of contagion continue to increase potentially, a 24-hour restriction would be considered. Activities 1. Represent in the form of an interval and on the number line the 4 cases of restrictions posed.
2. Solve the interval corresponding to the following operations: A∪B; C∩D
Step-by-step explanation:
1. The time in Hours is represented on the number line.
A) Restrictions From 12.00pm until 6.00am
In hours: 0 to 6.00am; 12.00pm to 24.00pm
(0, 6); (12, 24)
B. Restriction from 8.00pm to 6.00am
In hours: 20:00pm to 24.00pm; 0 to 6:00 am
(0, 6); (20, 24)
C. Restriction from 2.00pm to 6.00am
In hours: 14:00pm to 24.00pm; 0 to 6:00am
(0, 6); (14, 24)
D. 24hr restrictions
In hours: 00:00am until 24:00pm
(0, 24)
2. From the graph,
A ∪ B = (0, 6) ∪ (12, 24)
C ∩ D = (0, 6) ∩ (14, 24)
Where '∪' mean the union of A and B. That is, we combine all the element of A and B together.
And '∩' mean the intersection of C and D. That is we pick the values common to C and D.
B. surface of a sphere.
C. side of a cone.
D. side of a box.

Answer:
You need to paint 9 faces to earn $15 in profit.
Step-by-step explanation:
Given : You buy painting supplies for $12, and you charge $3 per person to paint faces.
To find : How many faces will you need to paint to earn $15 in profit?
Solution :
Let x represent the number of faces painted.
According to question,
Solving equation,
Therefore, You need to paint 9 faces to earn $15 in profit.
Investment = $12
For $15 profit, I have to earn, 12+15 = $27
Charge for 1 person(for paint faces) = 3
multiply by 9,
9 persons= $27
So, 9 person is the answer.
The number 81.54 is 107.99% percentage of 75.5
We have,
To find what percent of 75.5 is 81.54, we can use the following formula:
(81.54 / 75.5) * 100
Step 1: Divide 81.54 by 75.5:
81.54 / 75.5 ≈ 1.0799
Step 2: Multiply the result by 100 to convert it to a percentage:
1.0799 * 100 ≈ 107.99
Therefore, 81.54 is approximately 107.99% of 75.5.
To explain it further, if we consider 75.5 as the whole or 100%, then 81.54 is approximately 107.99% of that whole value.
