Determine the number that 88 is divisible by from the choices provided.(1 point)
To determine the number greater than 19 and less than 34 that is divisible by both 6 and 10, we need to check if each number in the given range satisfies the conditions.
Checking 24: 24 is divisible by 6 (24 ÷ 6 = 4) but not by 10.
Checking 60: 60 is divisible by both 6 (60 ÷ 6 = 10) and 10 (60 ÷ 10 = 6).
Checking 20: 20 is divisible by 10 (20 ÷ 10 = 2) but not by 6.
Checking 30: 30 is divisible by both 6 (30 ÷ 6 = 5) and 10 (30 ÷ 10 = 3).
Therefore, the number that is greater than 19 and less than 34, and divisible by both 6 and 10 is 30.
There are no choices provided, so it is not possible to determine the number that 88 is divisible by.

To determine the number that 88 is divisible by from the provided choices, we need to check if 88 is divisible by each choice.
Checking 88 divided by 5: 88 ÷ 5 = 17.6. Since the result is not a whole number, 88 is not divisible by 5.
Checking 88 divided by 6: 88 ÷ 6 = 14.6. Again, the result is not a whole number, so 88 is not divisible by 6.
Checking 88 divided by 3: 88 ÷ 3 = 29.3. Once more, the result is not a whole number, meaning 88 is not divisible by 3.
Finally, checking 88 divided by 2: 88 ÷ 2 = 44. Since the result is a whole number, we can conclude that 88 is divisible by 2.
So, from the provided choices, the number that 88 is divisible by is 2.

Identify a prime number between 40 and 50.(1 point)
To identify a prime number between 40 and 50, we need to check each number in the given range if it is divisible by any number other than 1 and itself.
Checking 41: 41 is a prime number.
Checking 42: 42 is divisible by 2, 3, 6, 7, 14, 21, and 42, so it is not a prime number.
Checking 43: 43 is a prime number.
Checking 44: 44 is divisible by 2, 4, 11, 22, and 44, so it is not a prime number.
Checking 45: 45 is divisible by 3, 5, 9, 15, and 45, so it is not a prime number.
Checking 46: 46 is divisible by 2, 23, and 46, so it is not a prime number.
Checking 47: 47 is a prime number.
Checking 48: 48 is divisible by 2, 3, 4, 6, 8, 12, 16, 24, and 48, so it is not a prime number.
Checking 49: 49 is divisible by 7 and 49, so it is not a prime number.
Checking 50: 50 is divisible by 2, 5, 10, 25, and 50, so it is not a prime number.
Therefore, the prime number between 40 and 50 is 41.

A composite number is a number that has factors other than 1 and itself. To identify the composite number among the given choices, we need to check if each number has factors other than 1 and itself.
Checking 71: 71 is a prime number since it is only divisible by 1 and 71.
Checking 31: 31 is a prime number since it is only divisible by 1 and 31.
Checking 51: 51 is divisible by factors other than 1 and itself. Specifically, it is divisible by 3 and 17. Therefore, 51 is a composite number.
Checking 61: 61 is a prime number since it is only divisible by 1 and 61.
Therefore, the composite number among the given choices is 51.
