23 weeks is how many months​
inna [77]

\huge \boxed{\mathfrak{Question} \downarrow}

  • How many months is 23 weeks?

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

Each month has at least 4 weeks, with some months having an extra day or two.

It's given to find how many months see there in 24 weeks. For this, we need to divide the given number of weeks (23) by the number of weeks in 1 month (4).

So,

\sf \: 23  \div  4 \\  =   \boxed{\boxed{ \bf \: 5.75 \approx \: 6 \: months}}

We can see that 23 weeks is <u>5.75 months which is approximately 6 months. </u>

__________________

If you want a more standard value then we can calculate weeks in 1 months as 4.345. Then, we must divide 23 weeks by 4.345.

\sf \: 23  \div 4.345 \\  =  \boxed{\boxed{ \bf \:  5.293 \: months}}

Now, we'll get the answer as <u>5.293 months</u>.

__________________

You can write the answer in either form. Your answer can be rounded of to 6 months in the 1st explanation or it can be written as 5 months if you followed the 2nd explanation. The given weeks is 23, an odd number..so it's hard to decide the correct number of months.

True or false if you are under the age of 21, you are considered DUI if your BAC is .02 or higher
Katarina [22]

The statement is false.

<h3><u>Explanation</u>:</h3>

The acronyms DUI stands for the Driving under influence and BAC stands for blood alcohol concentration. The blood alcohol concentration gives a value which signifies how many grams of alcohol is present in 100ml of blood. The BAC of a person is 0.2 means the person has 200mg of alcohol per 100ml of blood. Its much higher than the safety limit certified by American Medical Association.

The American Medical Association certifies that the maximum blood alcohol level can be upto 0.1 in worst case which can be allowed for a safe driving, although the levels under 0.05 are preferred. So the statement is false by its level.
