Okay, first, given the equation, we need to find out what the radius of the circle is. Let us state the general equation of a circle:
Where
is the centre of the circle. In this case, we don't need to know the centre. Just the radius.
Let us start by converting the equation into standard for, which I typed above. Divide both sides by 81.
Great! We now know the radius of the circle. It is
because it is the bottom fraction. Now we know that the radius is 9.
So now lets input this into the area of circle formula:
Now we insert our radius.
You can convert that into a decimal if you wish.
Hope this helped!

Answer:
The tip will be $3.05.
The bill will cost $18.28 with the tip and tax.
Step-by-step explanation:
14.50 + 5% (or 0.73) = 15.23
15.23 + 20% (or 3.05) = 18.28
Answer:
Step-by-step explanation:
The area of a regular polygon is
where a is the apothem and p is the perimeter. Perimeter is simple: just count the number of sides the polygon has and multiply it by 3 (the length of one side).
p = 3(9) is 27 inches for the perimeter.
We have what we need now to find the area:
and
so
A = 55.35 square inches
Hey there!
“Which expression is equivalent to b + b – 0.56b?”
• “b” or any other letter value is considered an “unknown number” so usually we label it/them as an invisible 1
• COMBINE the LIKE TERMS
(b + b – 0.56b)
(1b + 1b – 0.56b)
1b + 1b = 2b
2b – 0.56b = 1.44b
• Therefore, b + b – 0.56b is equivalent to 2b + 0.56b
Possible answer that you could be looking for: 2b + 0.56b ☑️
Good luck on your assignment and enjoy your day!

15444 ways we can choose 5 objects, without replacement, from 15 distinct objects.
Given that, suppose we want to choose 5 objects, without replacement, from 15 distinct objects.
<h3>What is a permutation?</h3>
A permutation is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters.
Now, 
= 13!/(13-5)!
= 13!/8! = 13x12x11x10x9= 1287 x 120 = 15,444
Therefore, 15444 ways we can choose 5 objects, without replacement, from 15 distinct objects.
