2/5 = 42
1/5 = 21
5/5 = 105
105 students in the class
Using Pythagoras Theorem,
(12)^2+ (a)^2= (13)^2
144+a^2= 169
a^2= 169-144
a^2= 25
a= √25
a= 5mm

The slope of line that passes through given points is -1/2
Step-by-step explanation:
The formula for slope is:

Given points are:
(-2,-1) = (x1,y1)
(2,-3) = (x2,y2)
Putting the values in the formula of slope
m =

Answer:
B.
Step-by-step explanation:
The answer is B because 3/5 of 1/2 is less than 1/2. The equation that represents this problem is
3/5 x 1/2 = 3/10
3/10 < 1/2
Therefore, 3/5 is less than 1/2!
