Which pair of measurements is not equivalent?3 hours, 10 minutes and 190 minutes
240 minutes, and 4 hours
350 minutes, and 5 hours, 50 minutes
480 minutes, and 6 hours

Answers

Answer:

480 minutes, and 6 hours

Step-by-step explanation:

At first we should know that

1 hour = 60 minutes

We will check which option is not equivalent.

1) 3 hours, 10 minutes and 190 minutes

3 hours, 10 minutes = 3 * 60 + 10 = 180 + 10 = 190 minutes

So, the pair of measurements is equivalent.

2) 240 minutes, and 4 hours

4 hours = 4 * 60 = 240 minutes

So, the pair of measurements is equivalent.

3) 350 minutes, and 5 hours, 50 minutes

5 hours, 50 minutes = 5 * 60 + 50 = 300 + 50 = 350 minutes

So, the pair of measurements is equivalent.

4) 480 minutes, and 6 hours

6 hours = 6 * 60 = 360 minutes

So, the pair of measurements is not equivalent.

The two points that lie on a line with an undefined slope are a) (-2,-3) and (2,-6) b) (-2,-3) and (-6, 2 c) (-2,-3) and (2,0) d) (-2,-3 )and (-2,6)

Answers

When you know 2 points on a line, the slope of the line is

(difference in y-values) / (difference in x-values).

The slope of the line that includes the points (-2,3) and (-2,6) ...
choice-d ... is
(6 - 3) / (-2 - -2) = 3 / 0 .

Division by zero is 'undefined'.

(On a graph, these two points are on a vertical line.)

The slope of the line that includes the points (-2,3) and (-2,6) ...
choice-d ... is
(6 - 3) / (-2 - -2) = 3 / 0 .
