What percent of 4 hours is 8 seconds?

2 answers:

8 0

To do this equation, you need to convert 4 hours into seconds, which is 14400 seconds. Or you can convert the 8 seconds to hours, which is 0.08 hours. Then, you have a fraction (8/14400) which you can convert into a decimal by dividing it. The answer to this is 0.0006. From here you can convert it to a percentage, which is 0.0006%

Choose the correct equation for the line shown on the graph?

fomenos

Answer:

y=-1/4x-1

How to find the slope

To find the slope of the line you need to do the change in y/change in x. This is also known as the rise/run. To do this you count the spaces in between the two points.

In this graph the change in y (rise) is 2. The change in x (run) is 8. Since the line is going down they are negative. The rise/run is -2/8. This can be simplified to -1/4.

Slope: -1/4x

How to find the y-intercept

To find the y-intercept, you need to look at where the line crosses y.

In this graph the line crosses y at -1.

Y-intercept: -1

Final equation: -1/4x-1
