The area of the circle is 254. 502 square units
How to determine the area
The formula for area of a circle is expressed as;
Area = πr²
Where;
r is the radius of a circle
Note that the radius of a circle with an inscribed triangle is expressed as;
Radius = ABC/4A
Where;
A, B and C are the sides of the inscribed triangle
Radius = 6 × 6 × 6 / 4(6)
Radius = 216/ 24
Radius = 9 units
Now, substitute the value of the radius into the formula
Area = 3. 142 × (9)²
Area = 3. 142 × 81
Area = 254. 502 square units
Thus, the area of the circle is 254. 502 square units

Explanation:
So, looking at the ruler, we;re going to take the whole number of the measurment from the whole bars of inches it overlaps (1-3) since we know it goes past there we will have a fraction beside it (because it does not go all the way to 4) If you see the longest lines in between the 3 and 4, there are 3 bars (which means each is 1/4.) Now, we know that it covers 3/4 of the last inch. To convert to /8, we multiply the numerator and denominator by 2 so we have 6/8. The CLOSEST (but not completely correct) (in 1/8 inches) would be D. (but ONLY if A is incorrect because that is simplified and the accurate answer.
A die was rolled 60 times. It landed on one—11 times, two—9 times, four—12 times, five—12 times, and six—8 times. What is the empirical probability of rolling a 5?
Answers
A die was rolled 60 times, then the empirical probability of rolled a five = 1/5.
An experiment is repeated a fixed number of times and each repetition is known as a trial. Mathematically, the formula for the experimental probability is defined by; Probability of an Event P(E) = Number of times an event occurs / Total number of trials.
Empirical probability = [tex]\frac{Number of favorable outcomes in experiment}{Total outcomes}[/tex]
Based on the given conditions,
Die was rolled 60 times.
That is,
Total outcomes = 60
She rolled One—11 times,
Two—9 times,
Four—12 times,
Five—12 times, and
Six—8 times.
But we can use rolling five,
That means, Five—12 times
And Total outcomes = 60
So,
We can write,
Number of favorable outcomes of getting 5 = 12
Then, the experimental probability rolled a five is given by,
= 12/60
= 1/5
Therefore, The empirical of probability of a rolled a five = 1/5.

Explain why the HCF of 81 and 154 must be 1.
Answers
the HCF of the numbers 81 and 154 must be 1.
HCF means the highest common factor that the two numbers have between them. When the numbers are divided by HCF, they become composite numbers. It is the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.
We are given two numbers:
81 and 154
We know that 81 is:
81 = 3 × 3 × 3 × 3
And 154 is:
154 = 2 × 7 × 11
We can see that both the numbers do not have any factor in common.
So, the highest common factor that is the HCF can be 1 only.
Therefore, the HCF of the numbers 81 and 154 must be 1.

Money is borrowed at 9% simple interest. After one year $615.85 pays off the loan. How much was originally borrowed?
Answers
Given the total amount paid off and the interest, the original amount borrowed within the given period of time is $565.00
How much was the original amount borrowed?Simple interest is simply a method to determine the amount of interest charged on a sum at a given rate and for a given period of time.
It can be expressed as;
A = P( 1 + rt )
Given the data in the question;
Annual interest rate r = 9% = 9/100 = 0.09Total amount A = $615.85 Time period t = 1 yearsPrincipal P = ?To determine the initial amount borrowed, plug the given values into the equation and solve for P.
A = P( 1 + rt )
615.85 = P( 1 + ( 0.09 × 1 ) )
615.85 = P( 1 + 0.09 )
615.85 = P( 1.09 )
P = 615.85 / 1.09
P = $565.00

The multiples of 4 are : 4, 8, 12, 16, 20, ...
The multiples of 5 are : 5, 10, 15, 20, ...

Angular kinetic energy, E, is the kinetic energy created by the rotation of an object and is described by the formula
E=Iw², where w is the angular velocity and I is the moment of inertia around the axis of rotation. What is the
formula solved for I?
Answers
The moment of inertia (I) solved for, from the angular kinetic energy formula is I = 2E/w².
Angular kinetic which is also referred to as rotational energy is simply the kinetic energy due to the rotation of an object.
It is expressed mathematically as;
E = (1/2)Iw²
To solve for I, we first reorder the equation to bring the term containing I to the left side.
E = (1/2)Iw²
(1/2)Iw² = E
Multiply both sides by 2
2 × (1/2)Iw² = 2 × E
Iw² = 2 × E
Iw² = 2E
Now, divide both sides by the question of I.
Iw²/w² = 2E/w²
I = 2E/w²
Therefore, the moment of inertia (I) solved for, from the angular kinetic energy formula is I = 2E/w².

Step-by-step explanation: The 2 would be used to double Mark's age since the question says Joey is twice Marks age. The +1 is used to add one more year after multiplying Mark's age by 2 since the question says Joey is one year older. For example if Mark's age is 2 then plug it into the equation 2(2)+1 which would make Joey's age 5.

As a result, this equation has had only one solution, x = 5/2. In contrast, a linear equation with two variables has two solutions.A linear equation for one variable is one that has only one variable of order 1. It has the formula ax + b = 0, in which x is a variable.For the given equation; -3/5 - 8³ + 3t.
The value of t = -1.5.
Put the value of 't' in the one degree linear equation.
