Determine whether the geometric series 17 + 12.75 + 9.5625 + ... converges or diverges, and identify the sum if it exists.
ANSWER
Converges
[tex]S_{ \infty } = 68[/tex]
EXPLANATION
The guy sequence is
17 + 12.75 + 9.5625 + ...
The common ratio is:
[tex] \frac{9.5625}{12.75} = \frac{12.75}{17} = \frac{3}{4} = r[/tex]
Since
[tex] |r| < 1[/tex]
the series converges.
The sum to infinity of this sequence is :
[tex]S_{ \infty } = \frac{a}{1 - r} [/tex]
where a=17 is the first term of the series.
[tex]S_{ \infty } = \frac{17}{1 - \frac{3}{4} } [/tex]
[tex]S_{ \infty } = \frac{17}{ \frac{1}{4} } = 68[/tex]

Step-by-step explanation:
Margin of Error is simply a range, an amount that is allowed for in case of miscalculation or change of circumstances. The margin of error is 5%.
1. Find the 5% of 3.20 = .16
2. Subtract and add .16 to 3.20 to get rid of that margin of error
3.20 + .16 = 3.36 and 3.20 - .16 = 3.04
3. 3.04 and 3.36
Answer:
b 3.04 to 3.36
Step-by-step explanation:
First we need to find 5% of 3.20
.05*3.20 = .16
To find the lower value, subtract 16 cents from 3.20
3.20-.16 = 3.04
To find the upper value, add 16 cent to 3.20
3.20 + .16 = 3.36
The range is 3.04 to 3.36
An opaque bag contains 5 green marbles 3 blue marbles and 2 red marbles. what is the of randomly picking out a marble and the marble being red?
Answer:
1/5
Step-by-step explanation:
Since there are 2 red marbles and since there are a total of 10 marbles, the probability is 2/10. This simplifies to 1/5. So the probability of picking a red marble is 1/5.
The probability of randomly picking out a red marble is 1/5
Calculating the probability of randomly picking out a marble and the marble being red?To determine the probability of randomly picking out a marble and it being red, we need to consider the total number of marbles and the number of red marbles.
Total marbles = 5 green + 3 blue + 2 red = 10 marbles
Red marbles = 2
So, we have
Probability = (Number of favorable outcomes) / (Total possible outcomes)
This gives
Probability = (Number of red marbles) / (Total marbles)
By subsituition
Probability = 2/10 = 1/5
Hence, the probability of randomly picking out a marble and it being red is 1/5

A bakery offers a sale price of $3.00 for 3 muffins. What is the price per dozen?
Answer:
$12 per dozen muffins
Step-by-step explanation:
3.00/3 = 1
1x = the price of one muffin
1(12) = 12
Step 1: Find what the price is per muffin. To do this you must divide $3.00 by 3 muffins (this will tell you dollar per muffin or $/muffin)
3 ÷ 3 = 1
This means that every muffin is $1
Since we know this, and we know that a dozen means 12 we can multiply 1 by 12 to find how much you would pay for a dozen muffins
12 × 1 = 12
It's $12 per dozen muffins

What is the equation of the line that passes through the point (-5, 2) and has an undefined slope?
Answer:
x = - 5
Step-by-step explanation:
A line with an undefined slope indicates that the line is vertical and parallel to the y- axis.
The equation of a vertical line is
x = c where c is the value of the x- coordinates the line passes through.
The line passes through (- 5, 2) with x- coordinate -5, hence
x = - 5 ← equation of line
The equation of a line that passes through the point (-5, 2) and has an undefined slope is x = -5.
i.e y-axis.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
We have,
The equation of a line passes through the point (-5, 2)
The equation of a line has an undefined slope.
Now,
An undefined slope means,
The line is parallel to the y-axis.
There is only one point on the x-axis.
Slope = Change in y-axis / Change in the x-axis
Slope= Change in y-axis / 0
Slope = undefined
If the slope of a line is undefined there is no y-intercept.
The equation of the line is:
y = mx + c
y = (1/0)x + 0
0 = x
x = 0
This means the y-axis.
The equation of the line passes through the point (-5, 2) so,
x = -5
Thus,
The equation of a line that passes through the point (-5, 2) and has an undefined slope is x = -5.

The length of a rectangle is eight more than twice the width. The perimeter is 64. Find the length and width
Answer:
24 and 8
Step-by-step explanation:
The formula for the perimeter of the rect. is P = 2W + 2L.
Here, L = 2W + 8, so the area formula becomes:
P = 2W + 2(2W + 8) = 64
Dividing all terms by 2 reduces this to:
W + 2W + 8 = 32, or 3W = 24, or W = 8.
Then: L = 2W + 8 = 2(8) + 8 = 24
Check: does 2W + 2L = 64 when these values for W and L are substituted?
Is 2(8) + 2(24) = 64 true? Yes
The length and width are 24 and 8 respectively.
The length of rectangle will be 8 units.
The width of rectangle will be 24 units.
What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The length of a rectangle is eight more than twice the width.
The perimeter is 64.
Now,
Let the width of rectangle = x
Then, The length of rectangle = 2x + 8
Here, The perimeter is 64.
So, We get;
2 (length + width) = 64
2 (2x + 8 + x) = 64
2 (3x + 8) = 64
3x + 8 = 64/2
3x + 8 = 32
3x = 32 - 8
3x = 24
x = 8
Thus, The width of rectangle = x
= 8
Then, The length of rectangle = 2x + 8
= 2 × 8 + 8
= 24
Therefore, The length of rectangle will be 8 units.
The width of rectangle will be 24 units.

Amanda is building a soft triangular kennel for her dog. She has four wooden planks of lengths 2 feet, 3 feet, 5 feet, and 6 feet. Determine which planks Amanda should use to build the triangular-shaped kennel. Enter the lengths from least to greatest.
Answer:
3 ft, 5ft, 6ft
Step-by-step explanation:
To build a kennel of my dog, I would try to make it the largest possible with what I have.
So, I would go with the 3 longest planks: 3ft, 5ft and 6ft.
By looking at the length, I see I could make something very close to a right triangle since I could use the 6ft as an hypotenuse, and have the two other sides as 3ft and 5 ft (6² is almost 3²+5², which equal 34).
That means my corner angle would be slightly over 90 degrees.

is actually 66 in. tall.
How tall is her dog?
A. 13.2 in.
B. 22.0 in.
C. 26.4 in.
D. 33.0 in.
HELP ASAP PLZ!!
Answer:
a. 13,2 in.
Step-by-step explanation:
66 : 2.5 = 26.4
0.5 x 26.4 = 13.2
By creating a proportion based on the heights shown in the photo and Alice's actual height, we can calculate that Alice's dog's actual height is 13.2 inches, which is option A.
To find out how tall Alice's dog is in reality, we need to use the ratio of their heights in the photograph to determine the dog's actual height. In the photograph, Alice's height is 2.5 inches and her dog's height is 0.5 inches, while her actual height is 66 inches. This creates a ratio that we can use to calculate the dog's actual height.
First, we set up a proportion where the height of Alice in the photo is to her actual height as the height of the dog in the photo is to the dog's actual height:
2.5 inches / 66 inches = 0.5 inches / x inches
Now we solve for x, which represents the dog's actual height:
x = (0.5 inches * 66 inches) / 2.5 inches
After performing the multiplication and division, we get:
x = 13.2 inches
Therefore, the height of Alice's dog in reality is 13.2 inches, which corresponds to option A.

Answer:
x = 4, y = 2
Step-by-step explanation:
Given the 2 equations
5x + 2y = 24 → (1)
5y = x + 6 → (2)
Rearrange (2) expressing x in terms of y by subtracting 6 from both sides
x = 5y - 6 → (3)
Substitute x = 5y - 6 into (1)
5(5y - 6) + 2y = 24 ← distribute and simplify left side
25y - 30 + 2y = 24
27y - 30 = 24 ( add 30 to both sides )
27y = 54 ( divide both sides by 27 )
y = 2
Substitute y = 2 into (3) for corresponding value of x
x = (5 × 2) - 6 = 10 - 6 = 4
The volume of a cube is 729 cubic feet . What is the side length of the cube ?
Side length of cube = 9 feet
The side length of the cube is 9 feet. Thus, the third option is correct.
To find the side length of a cube when given its volume, we can use the formula for the volume of a cube:
Volume = side length³
In this case, we know that the volume of the cube is 729 cubic feet.
Let's substitute this value into the formula:
729 = side length³
To find the side length, we need to take the cube root of both sides of the equation:
∛729 = ∛(side length³)
Simplifying:
9 = side length
Therefore, the side length of the cube is 9 feet.
