Answer:
b=7
Step-by-step explanation:
We want to determine the positive base b in which:

The easiest way to approach this is to convert all the numbers to base 10.


Next, we factorize the resulting expression.

The positive value of b for which the equality hold is 7.
If AC=BD, than Quad ABCD is a rectangle
AC
√(3+3)²+(6-1)²
√6²+5²
√36+25
√61
BD
√(1+1)²+(2-7)²
√2²+(-5)²
√4+25
√29
Quad ABCD is not a rectangle because √61 and √29 are not equal.
The answer should be 320 rods = 1 mile 5280 ft= 1 mile

Answer:
Range
Step-by-step explanation:
The range of a given set of data is the difference between the largest value and the smallest value in the data. For convenience and ease in the calculation, it is advisable to place the data in ascending order.
For example, given the following set of data:
4,9,5,6,2
To find the range;
<em>=> First arrange the data in ascending order</em>
2,4,5,6,9
<em>=> Find the smallest and largest numbers and then find their difference.</em>
Since the data has been arranged, it is obvious to see that the smallest number is <em>2</em> and the largest number is <em>9.</em>
Therefore the;
range = 9 -2 = 7
