Answer:
48 students.
Step-by-step explanation:
25% of total students = 12
suppose,
total students= x
so,
25% of x=12
(25/100)*x=12
25*x=(12*100)
x=1200/25
x=48
therefore,
x= total students= 48.
Confusing to me, sorry i cant help. I am not good with graphs.
Answer:
The expression that represents hourly rate Brendan earns working on a holiday is 
.
Step-by-step explanation:
Given:
Regular hourly rate = d
Percent extra Money earned on holidays = 25% more
We need to find expression represent the hourly rate Brendan earns working on a holiday.
Solution:
Extra money earned on holidays can be calculated by Percent extra Money earned on holidays multiplied by Regular hourly rate.
framing in equation form we get;
Extra money earned on holidays = 
Now we will find hourly rate Brendan earns working on a holiday.
hourly rate Brendan earns working on a holiday can be calculated by sum of Regular hourly rate plus Extra money earned on holidays.
framing in equation form we get;
hourly rate Brendan earns working on a holiday = 
Hence The expression that represents hourly rate Brendan earns working on a holiday is .
No.
EXPLANATION:
To tackled this problem we should find an equivalent denominator.
We find that the lcm ( lowest common denominator ) is 20.
1 x 5 = 5
4 x 5 = 20
2 x 4 = 8
5 x 4 = 20.
so the answer is no.
Set up a proportion to describe this relationship. So, for every 2 cats, there is five dogs. Therefore, “c” can represent your unknown quantity for every 35 animals.
2/5 = c/35
Cross multiply, multiplying the numerator/top number of the first fraction/ratio, by the denominator/bottom number in the second fraction/ratio.
2 • 35 = 70
Then, Cross multiply, multiplying the numerator/top number of the second fraction/ratio, by the denominator/bottom number in the first fraction/ratio.
C • 5 = 5c
So, now the problem shows both products as equal to each other.
70 = 5c
To solve for the variable, “c”, you must isolate the variable, by performing the opposite/inverse operation of multiplication, since that will undo the multiplication, for the variable to stand alone. Therefore, divide both sides of the equation by 5.
70/5 = 5c/5
14 = c
So, there is 14 cats out of 35 animals.
