down six over two im not sure though
Answer:
a) 2.5
b) 12
c) 40
Step-by-step explanation:
a) The ratio would be the relation between fixed and part time employees: for this would be 25/10= 2.5 Fixed per part time employee
b) Previous we got the ratio. So we have to divvide the 30 fixed by 2.5 to meet units
c) b) Previous we got the ratio. So we have to multiply the 16 for 2.5 to meet units
Answer:
800m
Step-by-step explanation:
First you multiply 20 by 60 to determine the amount of seconds in 20 minutes, which is 1200. then you divide 1200 by 1.5 to get the distance, which is 800m
Answer: the number of multiple-choice questions in the math test is 35 and the number of open-ended questions in the math test is 3
Step-by-step explanation:
Let x represent the number of multiple-choice questions in the math test.
Let y represent the number of open-ended questions in the math test.
The math test has 38 questions. It means that
x + y = 38
This test consists of multiple-choice questions worth 4 points each and open-ended questions worth 20 points each. The total number of points is 200. It means that
4x + 20y = 200 - - - - - - - - - -1
Substituting x = 38 - y into equation 1, it becomes
4(38 - y) + 20y = 200
152 - 4y + 20y = 200
- 4y + 20y = 200 - 152
16y = 48
48/16
y = 3
Substituting y = 3 into x = 38 - y, it becomes
x = 38 - 3 = 35
Answer:
8750
Explanation:
There are 5/5 math teachers in the university. 3/5 of them did not want to become math teachers which means 2/5 of the math teachers is equal to 3500.
3500=2/5
divide 3500 by 2 to get 1/5 of the math teachers.
3550/2=1750
1750 is 1/5 of the math teachers.
multiply 1750 by 5 to get 5/5 of the math teachers
1750*5= 8750
