Answer:
30 students
Step-by-step explanation:
3 students = 10% of the class.
x students = 90% of the class.
(If more, less divides. Let x be the subject. Since we know 10% of the class already, we have to find the remaining 90% that is 100% - 10% = 90%.)
x = 90%/ 10% × 3 students. ( the percentage signs cancel out and so do the zero's.)
x= 9/1 × 3 students ( 9/1 is the same as 9)
x= 27 students
(To find the total, you must add the 10% of the students to the remaining 90% of the students in the class.)
Total number of students in the class = 27 students + 3 students
= 30 students

Step-by-step explanation:
1. The sample of this study is 250 households in a cedar bluff. Population sample means the total number of units or participants are participating in a study to determine the result.
2. The population of interest refers to the objects and measurement through which a population sample can be measured to make a bold decision. Here, 4 pounds of garbage per day is a measurement to make a valuable decision to validate the study.
Do you know how to find area
Given:
Price of car = $32,000
Sales tax = 8%
To find:
The price of car including sales tax.
Solution:
We have,
Price of car = $32,000
Salas tax = 8%
Amount of sales tax = 8% of price of car
Now,
Total price of car including tax = Price of car + Sales tax
Therefore, the price of car including tax is $34560.
Answer:
m=2
Step-by-step explanation:
Add the numbers
-7+4m+10=15-2m
3+4m=15-2m
Rearrange terms
3+4m=15-2m
4m+3=15-2m
Rearrange terms
4m+3=15-2m
4m+3=-2m+15
Subtract 3 from both sides of the equation
4m+3=-2m+15
4m+3-3=-2m+15-3
Simplify
4m=-2m+12
Add 2m to both sides of the equation
4m=-2m+12
4m+2m=-2m+12+2m
Simplify
6m=12
Divide both sides of the equation by the same term
6m = 12
6m/6 = 12/6
Simplify
m = 2
