1. Set A represents rational numbers. Set B represents integers. Which diagram shows
gulaghasi [49]

Answer: Choice C) Upper right corner (aka northeast corner)

====================================================

Explanation:

Rational numbers are ones where we can write as a fraction of two integers. Any rational number is in the form a/b where a,b are integers and b is nonzero.

Terminating decimals can be written as a rational number. Something like 3.1 is equivalent to 31/10.

Of the four answer choices, only choice C is correct.

Choice A has the value '3' as a rational number, but it doesn't have it in the set of integers as well. So that's why choice A is incorrect.

Choice B has -3.4 in the set of integers, which is not correct. Integers do not have any decimal portion. The same applies to choice D also. We can rule choices B and D out.

Write the possible range of the measurement: 220 km ± 5%.
Alenkinab [10]
5% of 25 km is:

0.05*25 = 1.25 km

25 - 1.25 = 23.75

25 + 1.25 = 26.25

The possible range is (23.75, 26.25). Hope it helps
