Percent means per 100 so 40% 40 per 100, or simply 40/100
When we divide 40 by 100 we get 0.4 which is a decimal number.
to convert from percent to decimal you have to divide by 100, and then remove the % sign.

On a string of red and blue lights, the red lights blink everyb3 seconds, and the blue lights blink every 5 seconds. How many times will they blink at the same time in one minute?
The red and blue lights will blink at the same time 4 times in one minute.
Explanation:To determine how many times the red and blue lights will blink at the same time in one minute, we need to find the time at which both the 3-second cycle of the red light and the 5-second cycle of the blue light coincide. This is equivalent to finding the least common multiple (LCM) of 3 and 5. The LCM of 3 and 5 is 15, which means they will blink at the same time every 15 seconds.
Since there are 60 seconds in a minute, we need to find how many times 15 seconds fit into 60 seconds. 60 ÷ 15 = 4. Therefore, the red and blue lights will blink at the same time 4 times in one minute.
Answer: The red and blue lights will blink at the same time 4 times in one minute.

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.Mckenzie and Cara both tried to find the missing side of the right triangle.

Byun walked 15 blocks in 25 minutes. What was his average speed?
average = distance / time
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

72 is 48% of what number
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.
