IF THESE ARE WRONG CAN YOU LET ME KNOW?
AND COULD YOU ALSO HELP ME AND GIVE ME THE RIGHT ANSWERS?THANKS HAVE A GREAT DAY EVERYONE!
#1. so, what is 62/4?
#2. nope. 108 = 2^2 * 3^3
#3. yes! 2*3^2*5 = 90. 540=6*90, so we're cool.
#4. nope. did you even check with a calculator?
Please tell me the answers i need it soo badly
For the quick check:
1. D
2. D
3. B
4. C
Sure! Let's go through each question and find the correct answers together:
1. To determine if 1.62 is divisible by a number, we need to check if it evenly divides 1.62 without a remainder.
For option D (1, 2, 31, 62), let's check if 1.62 is divisible by each number:
- 1 is a divisor of any number, so it is divisible by 1.
- 2 is not a divisor of 1.62 because 1.62 divided by 2 is not a whole number.
- 31 is not a divisor of 1.62 because 1.62 divided by 31 is not a whole number.
- 62 is not a divisor of 1.62 because 1.62 divided by 62 is not a whole number.
Therefore, option D is incorrect.
The correct answer is option B (1, 2, 3, 31). 1.62 is divisible by 1 and 2.
2. For this question, we need to find which set of numbers can all divide 108 evenly.
Let's analyze option C (1, 2, 3, 6, 18, 36, 54, 108):
- 1 is a divisor of any number, so it is divisible by 1.
- 2 is a divisor of 108 because 108 divided by 2 equals 54, which is a whole number.
- 3 is a divisor of 108 because 108 divided by 3 equals 36, which is a whole number.
- 6 is a divisor of 108 because 108 divided by 6 equals 18, which is a whole number.
- 18 is a divisor of 108 because 108 divided by 18 equals 6, which is a whole number.
- 36 is a divisor of 108 because 108 divided by 36 equals 3, which is a whole number.
- However, 54 is not a divisor of 108 because 108 divided by 54 is 2, which is not a whole number.
- 108 is, of course, divisible by itself.
Therefore, option C is incorrect.
The correct answer is option A (1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108). All these numbers divide 108 evenly.
3. To find a number divisible by 2, 3, 5, 6, 9, and 10, we need to find a number that is divisible by the least common multiple of those numbers. The least common multiple of 2, 3, 5, 6, 9, and 10 is 90.
Option B (540) is divisible by 90 because 540 divided by 90 equals 6, which is a whole number.
Therefore, the correct answer is option B.
4. To determine if a number is divisible by 9, we need to check if the sum of its digits is divisible by 9.
For option B (520):
- The sum of its digits (5 + 2 + 0) equals 7, which is not divisible by 9.
Therefore, option B is incorrect.
None of the given options is divisible by 9. Please note that the number 5,432 is divisible by 9, but it is not provided as an option.
