Problem
500 students wore blue and 300 students did not. What percent of all the students attending the game wore blue?
Result
62.5% of all the students attending the game wore blue.
Solution
We can calculate the percent of students wearing blue, after finding the total amont of students, using division and multiplication.
Let's add
500 + 300 = 800
Let's divide
800/500 = 0.625
Let's multiply
0.625 · 100 = 62.5
Answer: first option
Step-by-step explanation:
Direct variation equation has the following form:
Where "k" is the constant of variation.
In direct variation when the variable "x" increases, the variable "y" increases by the same factor and when the variable "x" decreases, the variable "y" decreases by the same factor.
Inverse variation equation has the form:
Where "k" is the constant of variation.
In inverse variation when the variable "x" increases, the variable "y" decreases by the same factor and when and when the variable "x" decreases, the variable "y" increases by the same factor.
Given the equation:
You can observe that "r" varies directly with "l" and inversely with "p" and "t"
The answer to the question is: Yes.
Explanation: It can be solved by following exactly the same procedures
that solved the other two questions that you posted within the past 15 minutes.
Since I'm here already, here is the solution to this one:
6x² + 18x = 0
Divide each side of the equation by 6 :
x² + 3x = 0
Factor the left side:
x(x+ 3) = 0
This statement is true if x=0 or if x=3.
The solution to this one is even the same as the solution to the last one you posted.
You really ought to take a break, go back, review the solutions you've been given,
and try to solve a few on your own.
A)
25 to the power of 8
Hope this helps
A percentage is a number out of 100. So, 17.5% is really 17.5/100, or 0.175.
To find 17.5% of 1500, you multiply 1500 by 0.175
1500 x 0.175 = 262.5.
The commission is $262.50.
