The expression can be simplified as:
k^3(k7/5)^-5
= k^(3+-5) * (7/5)^-5
(Collecting the powers of k at one side and the constants at other side)
= k^-2 * (5/7)^5
(Solving thr integer powers)
= k^-2 * (3125/16807)
Answer:
A rational expression is a ratio of two polynomials. The domain of a rational expression is all real numbers except those that make the denominator equal to zero.
Step-by-step explanation:
Answer:
The answer is yes.
Step-by-step explanation:
3/4 US Cups or 0.75 US Cups of fluid is equal to 6 fluid ounces so if we add all the liquid that is given in fluid ounces together and divide the total amount by 6, then it would be equal to the total number of 3/4 US cups servings. So the answer is yes, the expression could be used to calculate the servings.
I hope this answer helps.

Answer:
Step-by-step explanation:
Question 1. 50% of what number is 100?
Number = x
50%x = 100
5x/10 = 100 (50% = 2/10)
5x = 1000 (Multiplying by 10 at both sides of the equation)
<u>x = 200</u> (Dividing by 5 at both sides of the equation)
<u>Part 50 Whole 100 Part 75 Whole 150 Part 100 Whole 200</u>
Question 2. 25% of what number is 30?
Number = x
25%x = 30
x/4 = 30 (25% = 1/4)
x = 120 (Multiplying by 4 at both sides of the equation)
<u>Part 25 Whole 30 Part 50 Whole 60 Part 75 Whole 90 Part 100 Whole 120</u>
<u>Question 3. What did you differently to find the whole using a ratio table?</u>
Using a ratio table is a much more simple path to get the whole. I take it and just calculate the double of the information given to me for completing the next values in my table, until I get the part 100 and its correspondent whole.
