4 x = 36
Step-by-step explanation:
Because the groups have an equal number of students, we assume that each of the groups has <em>x </em>number of students.
Therefore since there is <em>x</em> number of students in each of the 4 groups, there is 4 * x number of total students in all groups combined.
Since the question already indicates that there are a total of 36 students in the class, then we can indicate that..
4x = 36
Answer:
Step-by-step explanation:
Since π=3.14 and 1.75 should be half of π so cos(1.75) should be in the approximation of 
or 
.
Clearly Sam's calculator is in the degree mode since 
is about 
and obviously, 
, So on the unit circle, it will be in the second quadrant.
Thus, cos(1.75) is negative.
