Describe the difference between an exact value and an approximation when finding square roots of numbers that are not perfect squares. Give an example of each.
Answers
Final answer:
An exact value in square roots is the precise numerical value. It's typically computed from perfect squares. On the other hand, an approximation is given when dealing with numbers that aren't perfect squares and a precise square root cannot be calculated.
Explanation:
In mathematics, the terms exact value and approximation are often used when dealing with the concept of square roots and particularly, perfect squares.
An exact value is the precise numerical value of a square root. It's typically associated with perfect squares, as these can be exactly square rooted to a whole number. For instance, the square root of 25 (√25) is exactly 5 because 5*5 equals to 25.
On the other hand, an approximation is used when dealing with numbers that aren't perfect squares, and an exact square root cannot be found. For example, the square root of 10 (√10) cannot be expressed precisely as a whole or even as a simple fraction, so it is approximately 3.16.
It's important to understand the differencebetween these two concepts, especially when solving different mathematical problems.

What percentage of orange sodas sold are small, and what percentage of large servings sold are colas? Round your answers to the nearest whole number.
A. 29% of orange sodas sold are small, and 12% of large servings sold are colas.
B. 12% of orange sodas sold are small, and 53% of large servings sold are colas.
C. 53% of orange sodas sold are small, and 53% of large servings sold are colas.
D. 29% of orange sodas sold are small, and 53% of large servings sold are colas.
E. 53% of orange sodas sold are small, and 12% of large servings sold are colas.
Answers
Orange: 51 + 37 +9 = 97
cola: 66 +56 +17 = 139
Lemon: 57 + 48 + 6= 111
small: 51 +66 +57 = 174
medium: 37 + 56 +48 = 141
large: 9 +17 +6 = 32
percents of orange sodas are small: 51 / 97 = 0.526 = 53%
large servings are cola: 17 / 32 = 0.536 = 53%
Answer is C
53 percentage of orange sodas sold are small , and 53 percentage of large serving sold are colas.
What is percentage?
"Percentage is a number which represents the fraction of a number as its hundredth part."
Formula used
Percentage(%) = ( Value / Total value) × 100
According to the question,
As given in the table,
Total number Oranges soda = 51 + 37 + 9
= 97
Number of Small Oranges soda = 51
Substitute the value in the formula we get,
Percentage of orange sodas sold are small= (51 / 97) × 100
= 52.57%
= 53% (nearest whole number)
Total number of large sodas = 9 + 17 + 6
= 32
Number of large sodas are Cola = 17
Percentage of large sold sodas are colas = (17 / 32) × 100
= 53.125%
= 53% (nearest whole number)
Hence, Option(C) is the correct answer.
