At the beach, 20% of people are on the boardwalk and 23% are on the sand. If the rest are in the water, what percentage of people are in the water?

57%

Step-by-step explanation:

You need to find the percentage of people that are either on the boardwalk or the sand.  Do this by adding the two given percentages.

20% + 23% = 43%

Since the rest of the people are in the water, you can subtract the percentage found above (43%) by 100% to find the answer.

100% - 43% = 57%

The percentage of people in the water are 57%

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
