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
The answer is : 64 persons.
why? beceause 12,50 dollars x 64 is 800
Answer:
B = 40 degrees
A = 32.117
C = 42.005
Step-by-step explanation:
Based on the given data set:
x 1 2 3 4 5
y 1 8 27 64 125
the relationship between the two variables is notably:
y = x^3
this formula represents the volume of a cube:
V = s^3
Therefore, the answer is C) Side length and volume of a cube.
