Answer:
450 students
Step-by-step explanation:
Let s = number of students
1/2 are Americans 1/2s are Americans
s -1/2s = number of students left
1/2 s = number of students left
1/3 of the students left are Europeans
1/3 (1/2s) = 1/6s are Europeans
The rest are Australians = 150
Students = Americans + Europeans + Australians
s = 1/2s + 1/6s + 150
Combine like terms
s = 1/2*3/3 *s + 1/6s +150
s = 3/6s + 1/6s +150
s = 4/6s + 150
Subtract 4/6s from each side
s -4/6s = 150
6/6s - 4/6s = 150
2/6s = 150
1/3s = 150
Multiply each side by 3
3* 1/3s = 150*3
s = 450
There are 450 students

Answer:
1.292 x 10^7 cm^2
Step-by-step explanation:
Since the area of a rectangle is A = L x W and you are given the area and one side, you can rearrange this equation to solve for the other:
Therefore the length of the other side is 6 x 10^6.
The perimeter of a rectangle is P = 2L + 2W. We can solve that now that we have the length of the sides:
Answer:
17: A,C,B 18: C,A,B 19: A,C,B 20:A,C,B
Step-by-step explanation:
Slope(rate of change) can be found by dividing the change in y over the change in x. For example, #17 table, the change in y is (1-0)=1 and the change in x is (6-3)=3. Now, divide the to to get 1/3. Once you have all the rates of change you can list them in order.
