254.47 in²(rounded to nearest hundredth)
_________________________________________________________
[tex]A = \pi r^2[/tex]
tiny r means radius
² means multiply the number by itself twice
[tex]\pi r^2 = \pi * 9^2 = 81\pi(254.47~in^2)[/tex]
_________________________________________________________
Since the radius of a circle is 9 inches, the circle's area is equal to 254.34 square inches.
How to calculate the area of a circle?In Mathematics and Geometry, the area of a circle can be calculated by using this mathematical equation (formula):
Area = πr²
Where:
r represents the radius of a circle.
By substituting the given parameters into the formula for the area of a circle, we have the following;
Area of circle = 3.14 × 9²
Area of circle = 3.14 × 81
Area of circle = 254.34 square inches.

Step-by-step explanation:
a+2d=0
a+3d=6
d=6
a=6-3(6)
a=6-18
a= -12
a+(n-1)d
= -12+(n-1)6
= -12+6n-6
= -18+6n

The world health organization has studied the consumption of junk food in countries around the world since 2000. the function c = 179( 1.029 )^t models the amount of sods consumed in the world, where c is the amount consumed in billions of liters and t is the number of years since 2000.
approximately how much soda was being consumed when the study began in 2000?
Answer:
179 billion liters
Step-by-step explanation:
The variable t represents years since 2000, so in the year 2000 the value of t is zero.
When t=0, the exponential term is 1, so the value of the function is the multiplier of the exponential factor, 179.
__
Approximately 179 billion liters of soda was consumed in 2000.

A line plot with Kelly's lengths of ribbons is shown
What is the total length, in inches, for all pieces of ribbon?
Answer: (I changed it back to fraction form instead of decimal because it seems that is how you are doing it)
Two possible lengths of ribbon (In inches) are 25 and 133 3/4
Step-by-step explanation
Okay, so- First, You need to find out how much ribbon is there before the two additional ones are added. Like this:
12 + 14 2/4 + 14 3/4 = 41 1/4
Next, subtract that amount from 200 to get the number of inches of ribbon that are needed to get 200 inches of ribbon. Like this:
(I changed it to a decimal to make it easier, so don't mind that)
200 - 41.25 = 158.75
So, 158.75 inches of ribbon are needed to get 200 inches. You can subtract any number less than 158.75 from that to get two seperate ribbon measurements.
(This might sound confusing so here)
For example:
158.75 - 25 = 133.75 (The bolded numbers are the two measurements)
158.75 - 65 = 93.75
So, Two possible lengths (in inches) of ribbon that kelly could have added are "25" and "133.75 "
Two possible lengths (in inches) of ribbon that kelly could have added are also "65" and "93.75"

Graph function g when the value of h is -2. f(x) = |x| g(x) = f(x − h)
Using translation concepts, the graph of g(x) = |x + 2| is given at the end of the answer.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, we have that:
f(x) = |x|, h = -2, g(x) = f(x - h)
Hence, the equation of g(x) is:

The pressure at the depth of 5 meters will be 333.34 N / cm ²
What is pressure?Pressure is defined as the normal force acting at the per unit area of any object.
Given that:-
If the pressure is 200 newtons/cm2 at a depth of 3 m, calculate the pressure at a depth of 5 m.The pressure at the 5 m below sea level will be:-
3 m = 200
1 m = 200 / 3
5 m = 200/3 x 5
5m = 333.34 N / cm²

The sum of three times Annabell's age plus her mother's age is 42. He
mother is 6 more than 6 times Annabell's age. How old is Annabell?
Answer:
4
Step-by-step explanation:
First you have to analyze the word equations. Let x equal to Annabell's age and y equal her mother's age
3x + y = 42
6 + 6x = y
Then you use substitution to find x
3x + 6 + 6x = 42
9x = 36
x = 4
Jim anderson has a $150,000 whole life policy. what will the cash value of his policy be at the following anniversary dates? (use a thousands comma where applicable.) anniversary date cash value 15 year $ 25 year $
The cash value of Jim's policy at 15 years and 25 years are equal to $9,000 and $51,000 respectively.
How to calculate the cash value of Jim's policy?From the table shown in the image attached below, we can deduce that the cash value per unit for 15 years is given as:
15 years = $160.00 per unit.
Next, we would divide the face value of the policy by 1000:
Number of units = 150,000/1000
Number of units = 150.
Now, we can determine the cash value:
Cash value = 150 × 160
Cash value = $9,000.
The cash value per unit for 25 years is given as:
25 years = $340.00 per unit.
Next, we would divide the face value of the policy by 1000:
Number of units = 150,000/1000
Number of units = 150.
Now, we can determine the cash value:
Cash value = 150 × 340
Cash value = $51,000.

Answer:
15 years = 24,000.00
25 years = 51,000.00
Step-by-step explanation:
Hey, I'll explain how you solve these.
Since the value is 150,000, this has to be divided by 1,000.
That gives us 150.
Now you multiply 150 by the 15 yr cash value, which is 160.
This results in 24,000.00.
Since you have 150, you next need to multiply that by the 25 yr cash value, 340.
That gives us 51,000.00.

Radius is half the diamiter of a circle, basically the whole length from one point of the circle to the middle.
Answer:
Radius is how far the middle of the circle is from the edge of the circle. For example, we know that a circle has a middle point and we know that we have a line around it in the shape of a circle. The radius would be the distance from the middle point to the outer line of the circle.

Step-by-step explanation:
Given:
The double number line shows the price of 1 cupcake.
To Find:
Complete the table to show the same information as the double number line.
Solve:
Base on the 1st image:
1 cupcake costs $1.5.
Therefore, we can use the rule of three to complete the table.
If 1 cupcake costs $1.5 then 5 cupcakes would be $1.5 × =$7.50
And 18 cupcakes would be $1.5 × 18 =$27.
Then, 18 ÷ 1.5 = 12
As a result, 12 cupcakes costs $18.
Final Table:
Cupcakes Prices
5 $7.50
12 $18
18 $27

The number line shows the price of one cupcake
The price of 1 cupcake = $ 1.50
So ,
The price of 5 cupcakes = 5 x price of 1 cupcake
Substituting the values in the equation , we get
The price of 5 cupcakes = 5 x 1.50
The price of 5 cupcakes = $ 7.50
And , the number of cupcakes that can be bought for $ 18 is
Number of cupcakes for $ 18 = 18 / price of 1 cupcake
Substituting the values in the equation , we get
Number of cupcakes for $ 18 = 18 / 1.5
Number of cupcakes for $ 18 = 12 cupcakes
And , the price of 18 cupcakes is = 18 x price of 1 cupcake
Substituting the values in the equation , we get
The price of 18 cupcakes = 18 x 1.5
The price of 18 cupcakes = $ 27
Hence , The price of 5 cupcakes = $ 7.50
The number of cupcakes for $ 18 = 12 cupcakes
