Well range is the difference between the highest and lowest numbers so 20-7 is 13
Answer:

Explanation:
Given the irrational numbers:

In order to arrange the numbers from the least to the greatest, we convert each number into its decimal equivalent.

Finally, sort these numbers in ascending order..

The given numbers in ascending order is:

Note: In your solution, you can make the conversion of each irrational begin on a new line.
Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).
A.

Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.

Indeed, those two numbers are relatively prime.
Answer:
0.92
Step-by-step explanation:
cosine = adjacent/ hypotenuse
cosine of t = 12/ 13
cos t= 0.92308
The question is find the total cost when the price is $89.75 and the tax is 7 1/4%
Total cost = price + tax
Tax = 7 1/4 % of price
Tax rate = [7 + 1/4] = 7.25 %
Tax = 7.25 % * price = 7.25 % * $89.75 = $[7.25/100] * 89.75 = $6.51
Total cost = $89.75 + $ 6.51 = $96.26
