Answer:
A. 30 two-point questions and 10 four-point questions
Step-by-step explanation:
30 multiplied by 2 equals 60
10 multiplied by 4 equals 40
60 plus 40 equals 100 points which is the amount of points the test is worth as stated i the question.
30 plus 10 equals 40, which is the total amount of questions in the test as stated in the question.
If I’m not mistaken, the answer should be C.
Let me know if I was correct.
Answer: 0.72/20; 1.98/20; 17.3/20
0.036 * 10/10 = 0.36/10 * 2/2 = 0.72/20
0.099 * 10/10 = 0.99/10 * 2/2 = 1.98/20
0.865 * 10/10 = 8.65/10 * 2/2 = 17.3/20
Given parameters:
y varies directly as w;
This interpreted implies that as y increases, we increases by a certain factor or amount;
So, y ∝ w
y = kw
where k is the constant of proportionality
Now, given that y = 8 and w = 2
Input in the equation to solve for k;
8 = k x 2
Solving k gives, k = 4
Now to the second part,
if v is directly proportional to w;
v = k w
So v = 4w
The equation that relates v to w is v = 4w
