18 girls represent 56.25 percent of the total number of students.
To find what percent 18 girls out of 32 students represent, you can set up a proportion comparing the number of girls to the total number of students. This proportion is represented by the fraction 18/32. To convert this fraction into a percentage, multiply it by 100.
Here's the calculation step by step:
Divide 18 by 32 to get the decimal form.
Multiply the result by 100 to get the percentage.
Performing the calculation gives:
(18/32) x 100 = 56.25%
Therefore, 18 girls represent 56.25 percent of the total number of students.

Distributive Property
Reflexive Property of Congruence justifies the following statement ∠AOB ≅ ∠AOB. Option B is correct.
What are the angle?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
∠AOB ≅ ∠BOB
It can be obtained, only by when the angle gets reflected.

How many ways are there of seating six people at a round table so that two specific people sit together?
Answer:
6 People in a round table can be seated in (6 - 1) ! ways = 120. Now we need to subtract the number of cases when one of those is sitting next to 2 of the other 5. We can consider as if 5 people are sitting in a row because it is round table.
The set of complex numbers is closed under subtraction. true or false
The set of complex numbers is indeed closed under subtraction because the subtraction of any two complex numbers always results in another complex number.
Explanation:The set of complex numbers being closed under subtraction is indeed true. In mathematics, a set is said to be closed under a particular operation if performing that operation on members within the set always results in a member that is also within that set.
In the case of complex numbers, if we subtract one complex number from another, the result is a complex number. For example, if we have two complex numbers, (a + bi) and (c + di), and we subtract the latter from the former, the result will be a complex number (a - c) + (b - d)i.

Which of the following is the correct action to take when simplifying the expression A. add the exponents B. subtract the exponents C. multiply the exponents D. divide the exponents
Final answer:
To simplify an expression involving division of exponential terms with the same base, subtract the exponents of those terms. Numerical coefficients are divided normally while applying the subtraction rule to the exponents.
Explanation:
When simplifying the expression that involves division of exponentials, the correct action is to subtract the exponents. This rule applies when the bases of the exponential terms are the same. For example, when dividing [tex]a^m[/tex] by [tex]a^n[/tex], you would calculate a^(m-n). If we have numerical coefficients in front of the terms, we divide those normally, then apply the rule for exponents. An example is 4.5 × [tex]10^9[/tex] / [tex]10^6[/tex] = 4.5 × [tex]10^(9-6)[/tex] = 4.5 × [tex]10^3[/tex].

If Consider today’s stock listing for Enam Telecom, shown below.
52 wk High52 wk LowSymbolDiv.CloseNet Change122.8664.77ENM3.4599.144.74if the lowest price in the past year occurred 48 days ago, find the approximate average change per day since then. a. $4.74 b. $0.72 c. $0.49 d. $1.34
Answer:
Average change per day since then = $0.72
Step-by-step explanation:
Stock listing for Enam Telecom is given as
52 wk high 52 wk low Symbol Div. Close Net change
122.866 64.77 ENM 3.45 99.14 4.74
The lowest price $64.77 occurred 48 days ago.
Today's close for the stock was $99.14.
Now we have been asked to tell the approximate average change per day since then.
Therefore Average change per day = (closing value for today - closing value 48 days ago) ÷ (number of days)
Since closing value 48 days ago = 52 week low = $64.77
Now average change = [tex]\frac{(99.14-64.77)}{48}=0.72[/tex]
Therefore answer is $0.72 is the average change per day.
The approximate average change per day since the lowest price occurred is approximately $0.72, option B is correct.
To find the approximate average change per day since the lowest price occurred 48 days ago, we need to calculate the total change and divide it by the number of days.
The lowest price in the past year was 64.77, and the current price is 99.14.
The change in price is the difference between these two values:
Change = 99.14 - 64.77
= 34.37
Now, we divide the total change by the number of days:
Average Change per Day = Change / Number of Days
Average Change per Day = 34.37 / 48
Average Change per Day = 0.716
Hence, the approximate average change per day since the lowest price occurred is approximately $0.72.
Therefore, the correct option is b. $0.72.

Paula is working on her English essay. She already has 150 words written and has planned out the rest. Paula's essay must be 3,000 words in length, and she types at a rate of 38 words per minute.
Which equation represents the number of words in her essay, and how many minutes, m, will it take Paula to complete it?
a) 38m - 150 = 3,000; m = 75 minutes
b) 38m - 150 = 3,000; m = 83 minutes
c) 38m + 150 = 3,000; m = 75 minutes
d) 38m + 150 = 3,000; m = 83 minutes
The correct equation for the given scenario is 38m + 150 = 3,000. Solving this equation, we find that it will take Paula approximately 75 minutes to finish her essay.
Explanation:The question involves calculating how much time Paula needs to complete her essay based on her typing speed and desired essay length. Paula needs to write 3,000 words, but she already has 150 written. Therefore, she needs to write 3,000 - 150 = 2,850 more words. If she types at a rate of 38 words per minute, the number of minutes, represented as m, can be found using the equation 38m = 2,850. Therefore, the correct equation from the options is 38m + 150 = 3,000. Solving this equation for m gives m = 2,850 / 38 ≈ 75 minutes. Thus, option c) 38m + 150 = 3,000; m = 75 minutes is the correct answer.

Answer:
1/5
Step-by-step explanation:
5y = x - 3
To find the slope of a line, we need to get the equation in the form y= mx+b where m is the slope and b is the y intercept
5y = x - 3
Divide each side by 5
5y/5 = x/5 - 3/5
y = 1/5 x - 3/5

Dylan scored a total of 48 points in first 4 games of the basketball season. Which equation can be used to find g, the average number of points he scores per game?
Answer:
[tex]g = \frac{48}{4}[/tex]
Step-by-step explanation:
[tex]Average = \frac{\text{Sum of all observations}}{\text{No. of observations}}[/tex]
[tex]Average = \frac{\text{Total score}}{\text{Total no. of games}}[/tex]
Since we are given that Dylan scored a total of 48 points in first 4 games of the basketball season.
So,[tex]Average = \frac{48}{4}[/tex]
Let the average be g
So, [tex]g = \frac{48}{4}[/tex]
Hence The equation can be used to find g, the average number of points he scores per game is [tex]g = \frac{48}{4}[/tex]
