Answer: 5%
Step-by-step explanation:
First and foremost, we need to know that 60 minutes = 1 hour. Therefore,
7 hours = 60 × 7 = 420 minutes.
Number of minutes awake = 21 minutes
Number of minutes supposed to be asleep = 7 hours = 420 minutes
The percentage of the seven hours that Frank was awake during the night will be:
= 21/420 × 100
= 1/20 × 100.
= 5%

Triangle ABD and ADC are righttriangles so u can use the Pythagorean theorem/triples. the triples are 3/4/5 and 5/12/13. 12 is 4x3, and 15 is 5x3, so BD is 3x3, which is 9. AC is 13, as it is part of the Pythagorean’s triples
Answer is: Irrational because if the answer doesn’t repeat for an example 0.392827263, it’s irrational if it does repeat like this 0.3434343434 it’s rational! Hoped this helped!!
