Step 1:
Calculate the square root of 60 to be:
√60 = 7.74596669241483
Step 2:
Reduce the tail of the answer above to two numbers after the decimal point:
7.74
Step 3:
Round 7.74 so you only have one digit after the decimal point to get the answer:
7.7
To check that the answer is correct, use your calculator to confirm that 7.72 is about 60.

Answer:
25
Step-by-step explanation:
Let x be the number of students in the class
15 is 60% of x
60% of x can be written as 0.6x
15 = 0.6x
Divide by 0.6 on both sides
25 = x
There are 25 students in the class

Answer: Option B
Step-by-step explanation:
The equation of a line has the following form:
Where m is the slope of the line and b is the intersection with the y axis
So the slope of the line 
is 
By definition if two lines are parallel then they will have the same slope. Therefore the line parallel to will have the same slope:
To find b we substitute point (3, 4) in the equation and solve for b
Then the equation is:
