6: The integer must end in either a 0, 2, 4, 6, or 8, and the sum of its digits is divisible by 3. (Example. 24. Ends in a 4, and sum of digits (2+4 = 6) is divisible by 3)
7: To determine if the number 672 is divisible by 7, start by multiplying the last digit by 2, which in this case results in 4. Subtracting this from the rest of the number, 67 minus 4, yields 63. Since 63 can be divided by 7 evenly to result in 9, it is simple to conclude that 672 is divisible by 7.
8:
A number is divisible by 8 if the number formed by its last three digits is divisible by 8. 3240 is divisible by 8, because 240 is divisible by 8. 3145 is not divisible by 8, because 145 is not divisible by 8.
9: This is similar to the rule for 3. A number is divisible by 9 if the sum of its digits is divisible by 9. 7065 is divisible by 9, because 7 + 0 + 6 + 5 = 18 which is divisible by 9. 3045 is therefore not divisible by 9, because 12 is not divisible by 9.
57.55 in base 10 equal in base 2 is 57.55₁₀ = 111001.10001100110₂
Base 10:
It refers the decimal number system.
A number system which uses digits from 0 to 9 to represent a number.
Base 2:
It refers the Binary number system.
A binary number is defined as a number that is expressed in the binary system or base 2 numeral system. It describes numeric values by two separate symbols; 1 (one) and 0 (zero).
Given,
The base 10 number = 57.55
Now we have to convert it into base 2,
So, the conversion will follow the following step in image 1.
Write the Remainders from bottom to top
So, 57₁₀=111001₂
For Decimal Numbers
Refer image 2,
Write the Integer part from top to bottom
55₁₀ = 10001100110₂
Therefore,
57.55₁₀ = 111001.10001100110₂

Answer: 59 degrees
Step-by-step explanation:
90-31=59
Answer:
The range is 58
Step-by-step explanation:
In math, the range of a data set is the difference between the highest and lowest value. In this data set, we can see that the highest value is 65, and the lowest value is 7. 65 - 7 = 58.
