Answer:
3 1/2
Step-by-step explanation:
if you multiply 4 and 3 you 12 if you multiply 1/2 times 3 you get 1 1/2 and 1 1/2 + 12 = 13 1/2 and then you have to find a fraction that when multiplied by 4 1/2 you get 2 1/4 and 4 1/2 × 1/2 = 2 1/4 so 2 1/4 + 13 1/2 = 15 3/4
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%
Yes, the only odd composite numbers below 20 are 9 and 15.
9 can be divisible by 1,3, and itself
15 can be divisible by 1,3,5, and itself
Answer:
To calculate , calculate the quotient of two consecutive terms.
For all , , so the series converges, as the series grows (even more than) exponentially.
Answer:
Yes
Step-by-step explanation
For one book it is $2.25. So take $2.25 and multiply that by 4, and you get $9. That shows a proportional relationship.
