74% of the lottery tickets were sold. If the number of lottery tickets was 5032 how many total tickets were sold
emmainna [20.7K]

Answer:

3,724 lottery tickets were sold.

Explanation:

When you say percent, it means a part for every one hundred. So when you say 74% it can be expressed as the fraction:

\dfrac{74}{100}

To determine how many tickets were sold, you need to find a fraction or a ratio that is proportional to 74/100 where 5032 is proportional to 100.

\dfrac{x}{5,032} = \dfrac{74}{100}\\\\x = \dfrac{74\times5,032}{100}

x = \dfrac{372,368}{100}=3,723.68\; tickets\:were\:sold

But since you cannot sell only part of a ticket, we round that up to the nearest whole number:

3,724

Read the passage. What is the meaning of the euphemism "I have been stilled”?
lianna [129]

Answer:

The correct answer is: I have died.

Explanation:

A euphemism is a word or a phrase that is substituted for a word or phrase that is considered to be too blunt or too straightforward when referring to something disturbing, sad, upsetting etc. 'I have been stilled' is a much gentler way of saying 'I have died'
