According to a survey of workers, 5/25 of them walk to work, 1/25 bike, 4/25 carpool, and 15/25 drive alone. What percent of workers walk or bike to work?

24%

Step-by-step explanation:

First add up the proportion of people who walk to work and those who bike as well. This will show the proportion of people who walk or bike to work.

This is:

= 5/25 + 1/25

= 6/25

Then convert this to a percentage:

= 6/25 * 100

= 24%

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
