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.
If we convert the given in its mathematical form, we have,
(30x⁶/14y⁵)(7y²/6x⁴)
It can be observed that the numerator of the first and the denominator of the second have a common factor of 6x⁴. Also, the denominator of the first and the numerator of the second expression have a common factor of 7y².
((6x⁴)(5x²)/(7y²)(2y³))(7y²/6x⁴)
Cancellation of the common terms will give us an answer of,
<em>5x²/2y³
</em><em />Therefore, the simplified version of the involved operation is 5x²/2y³. <em>

Pythagorean theorem
c2 = a2 + b2
58^2 = 42^2 + b2
3364 = 1764 + b2
1600 = b2
b = 40
