Answer:
The probability of rolling a factor of 9 is 1/2, or 50%.
Step-by-step explanation:
The number 9's factors are 1, 3, and 9. Three of the six sides of the cube have a factor of 9. Therefore 3/6 of the sides are factors of nine.
Simplify 3/6 to 1/2 to get a probability of 50%.
Answer:
34 minutes
Step-by-step explanation:
Given


Required
Number of minutes left to spend (x)
Since there's only 1 minute left to spend on every other call;
Time left = x * 1
Time left = x
The required can further be calculated using:

This gives:

Subtract 6 from both sides


<em>Hence, there are 34 minutes left to spend</em>
Answer:
y = -9/10x + 3/10 or y = 3/10(1 - 3x)
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of one another
so slope of line w is -9/10
Using (-3,3) >> y = -9/10x + b
3 = -9/10(-3) + b
3 = 27/10 + b
b = 3 - 27/10 = 30/10 - 27/10 = 3/10
y = -9/10x + 3/10 or y = 3/10(1 - 3x)
