B

Step-by-step explanation:

Remind what are the elements of all given sets.

Natural numbers are numbers used when counting 1, 2, 3, 4, ...

Whole numbers are numbers 0, 1, 2, 3, 4, ... (natural numbers and 0)

Integers are natural numbers, 0 and negative numbers (see attacged diagram for details).

Rational numbers are numbers that can be written as fractions of integers and natural numbers.

You are given number 8.25. This number can be written as

This number is not a whole number, is not an integer, but is rational because it can be written as fraction.

1st part is 64,000,000

2nd part 500,000

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
