Hey there! I'm happy to help!

The area of a circle is the radius squared multiplied by pi (we will use 3.14). We already have the area, so we will go backwards.

1441÷3.14≈458.9171975

We find the square root.

√458.9≈21.42235275

Now we have our approximate radius. The diameter is twice the radius.

21.42235275×2=42.8447055

I don't know exactly if they want you to round it or not, but the diameter is somewhere around there.

Have a wonderful day! :D

Answer:

C

Step-by-step explanation:

Decreased price = 16.50 - 12 = $ 4.50

Percent of decrease =

=\frac{4.50}{16.50}*100\\\\= 27.27

= 27%

Give the solution set for the inequality<br> 7x &lt; 7(x - 2) in interval notation.
eduard

<u>ANSWER:</u>

The solution set for the inequality 7x < 7(x - 2) is null set \varnothing

<u>SOLUTION:</u>

Given, inequality expression is 7x < 7 × (x – 2)

We have to give the solution set for above inequality expression in the interval notation form.

Now, let us solve the inequality expression for x.

Then, 7x < 7 × (x – 2)

7x < 7 × x – 2 × 7

7x < 7x – 14

7x – (7x – 14) < 0

7x – 7x + 14 < 0

0 + 14 < 0

14 < 0  

Which is false, so there exists no solution for x which can satisfy the given equation.

So, the interval solution for given inequality will be null set

Hence, the solution set is \varnothing
