Answer:
each person has to pay 12.82
Answer:
She typed 32 words in her letter
Step-by-step explanation:
Assume that the letter has x words
∵ She typed x words in her letter
∵ She misspelled 8 words
∵ She misspelled 25% of the words she typed
∴ She misspelled 25% of x
→ That means 8 is equivalent to 25% of x
∴ 25% of x = 8
∴ 25% × x = 8
→ Change 25% to decimal by divide it by 100
∵ 25% = 25 ÷ 100 = 0.25
∴ 0.25 × x = 8
∴ 0.25x = 8
→ Divide both sides by 0.25
∵ =
∴ x = 32
∵ x represents the number of words that she typed in the letter
∴ She typed 32 words in her letter
A typical example of a rational exponent and radicals is a^x/y = y√(a)^x
<h3>What is a rational exponent?</h3>
We have a rational exponent when a number is raised to a power such as x/y. In this case, we must know that; a^x/y is the same as y√(a)^x.
Now let me give you a specific example. Assuming that a write something like 5^3/2. This would be the same as saying √(5)^3.
