Answer:
Between all these pairs of numbers,a rational number can be found in all the 3 pairs
Step-by-step explanation:
PAIR1: -10 and -9
Rational numbers are: -10.5,-10.6,-10.1,etc (there are way more)
PAIR2: 5.91 and 5.92
Rational numbers:- 5.915,5.916,etc(there are way more)
PAIR3:2/3 and 4/5
LCM= 15
2/3=10/15
4/5=12/15 between these two (10/15 & 12/15)
Rational numbers: 11/15, 11.5/15(because it's result would be a recurring/repeating decimal),etc

This question is incomplete, the complete question is;
A household item uses 321 watts of electricity. This item is used for 27 hours each week. How much CO2 will be produced each week from this item? (assume 1.37 pounds of CO2 is produced per KWH of electricity used)
Answer: 11.87 lbs of CO2 will be produced each week from this item
Step-by-step explanation:
Given that;
Average wattage Wattage of the item = 321 watts
Time used = 27 hours each week
CO2 produced each week = ?
so;
Total electricity consume = 321 × 27 = 8667 watt = 8.667 kWh
given that; 1.37 pounds of CO2 is produced per KWH of electricity used
hence; CO2 generated by our item will be;
⇒ 8.667 kWh × 1.37
= 11.87 lbs
Therefore, 11.87 lbs of CO2 will be produced each week from this item
The answer is C. Sometimes because if the two lines never intersect, they could still no be parallel.
