two cylindrical candles have a scale factor of 3:5. The larger candle has a volume of 40(3.14) cubic inches. Fund the volume of thel the smaller candle. Write your answer in term of (3.14)
Answers
[tex]5 = 40\pi \\ 3 =( (40 \div 5) \times 3)\pi \\ = 24\pi[/tex]
The volume of the smaller candle is 8.64π cubic inches.
How to find the volume
The volume of a cylinder is given by the formula
V = π r² h,
where
r is the radius and
h is the height.
The scale factor is given as 3:5, which means the ratio of the volumes is (3³ : 5³)
Using the ratio, let volume of the the smaller candle. be x
3³ : 5³
x : 40π
cross multiply
x = 40π * 3³ / 5³
x = 40π * 27 / 125
x = 8.64π cubic inches.

During a basketball game a player makes 12 of 18 free throws attempted write the ratio as fraction reduced to the lowest term
Answers
Final answer:
The ratio of free throws made to free throws attempted by the player is 12/18, which can be reduced to its lowest terms by dividing both numbers by their greatest common divisor, 6, resulting in the reduced fraction 2/3.
Explanation:
To find the ratio of free throws made to free throws attempted, we start by looking at the numbers given: 12 made out of 18 attempted. We express this ratio as a fraction 12/18.
To reduce this fraction to its lowest terms, we need to find the greatest common divisor (GCD) that divides both numerator and denominator evenly.
In this case, the number 6 is the GCD of 12 and 18. Dividing both the numerator and the denominator by 6, we get 2/3.
Hence, the ratio of free throws made to free throws attempted, reduced to the lowest term, is 2/3.

C. A common ratio less than 0
D. A common difference greater than 0
Answers
B. A common ratio between 0 and 1 would result in decay, not growth
C. A common ratio less than one would just reflect the graph across the x-axis. It does not give any information about whether or not it is exponential growth.
D. Exponential growth functions have no common differences.
Thus, A is the correct answer.
Exponential growth features a quantity increasing at a constant growth rate. The correct answer is Option A.
Exponential growth is characterized by a situation where a quantity increases at a constant growth rate. It is often represented graphically by an increasing curve.
This means that as time progresses, the rate at which the quantity grows also increases. For example, the population of a species might grow slowly at first, but as it becomes larger, the growth rate accelerates.

The students walk to school is 175.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
let the ratio of students who walk to students who take bus = 5: 7
let the common ratio be x.
So, Number of students who walk = 5x
and, Number of students who Bus= 7x
Total students= 420
So, 5x+ 7x = 420
12x= 420
x= 35
Hence, students walk to school =5 x 35 = 175.

(10⁰x 10¹ x 1¹⁰), (10⁰ + 10¹x 1¹⁰), (10⁰ + 10¹ + 1¹⁰), (10 x 10¹).
Explanation:
To arrange the expressions in increasing order of their values, we must first calculate the value of each expression.
(10⁰ x 10¹ x 1¹⁰): Here, 10⁰ = 1, 10¹ = 10, and 1¹⁰ = 1 (since any number to the power of zero is 1). Multiplying these together, we get 1 x 10 x 1 = 10.(10 x 10¹): This equals 10 x 10 = 100.(10⁰+10¹+1¹⁰): Adding these values together gives us 1 + 10 + 1 = 12.(10⁰+10¹ x 1¹⁰): Following the rules of operations (multiply before adding), first calculate 10¹ x 1¹⁰ which equals 10 x 1 = 10, then add 10⁰ which is 1. So, this gives 1 + 10 = 11.Now we can arrange the expressions in increasing order:

A rectangular table is six times as long as it is wide. If the area is 294 ftsquared, find the length and the width of the table.
Answers
please respond back if it was correct
the width of a rectangular table is 7 feet and the length of a rectangular table is 42 feet.
The area of a rectangular table is 294 ft².
What is the area of a rectangle?The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.
Let the width of a rectangular table be x.
Then, six times as long as it is wide = 6x
Area of a rectangular table = 6x × x
⇒ 6x²=294
⇒ x²=49
⇒ x=7 feet
So, length=6x=42 feet
Therefore, the width of a rectangular table is 7 feet and the length of a rectangular table is 42 feet.

The formula is [f(-1)-f(-4)]/[3]
The value of f(-1) is 3
The value of f(-4) is -3
The average rate of change is 2
==============================================
Explanation:
For the first blank, we use the formula
[ f(b) - f(a) ]/[ b - a ]
where 'a' and 'b' are the endpoints for the x interval
In this case, a = -4 and b = -1. When you plug those values into the formula above, you get...
[ f(b) - f(a) ]/[ b - a]
[ f(-1) - f(-4)]/[ -1 - (-4) ]
[ f(-1) - f(-4)]/[ -1+4 ]
[ f(-1) - f(-4)]/[ 3 ]
which is why the answer is choice C for the first blank
-------------------------------------------
To compute the value of f(-1), we draw a vertical line through -1 on the x axis. This vertical line crosses the diagonal function graph at the point (-1,3). The y value of this point is what we want. Plugging in x = -1 leads to y = 3. This is why f(-1) = 3
If you want, you can draw a horizontal line through (-1,3) and you'll see it touching 3 on the y axis.
-------------------------------------------
Follow similar steps as above to compute f(-4). Draw a vertical line through x = -4 on the x axis. Mark the point where the vertical line crosses the diagonal line. This point is (-4,-3). Optionally draw a horizontal line over til you hit the y axis and you'll find that y = -3 corresponds to x = -4
This is why f(-4) = -3
-------------------------------------------
We'll use the last three sections to compute the average rate of change. Everything combines together building up to this moment.
From the first part, we had the formula
[ f(b) - f(a) ]/[ b - a ]
[ f(-1) - f(-4)]/[ 3 ]
We can replace the "f(-1)" with 3 since we found that f(-1) = 3
Similarly, f(-4) = -3 so we can replace the "f(-4)" with -3
Doing those replacements and simplifying leads to...
[ f(-1) - f(-4)]/[ 3 ]
[ 3 - (-3)]/[ 3 ]
[ 3 + 3]/[ 3 ]
6/3
2
So the average rate of change is 2
Note: because the entire graph is a straight line, the average rate of change for any interval a < x < b is going to be equal to the slope m. In this case, the slope of the line is m = 2/1 = 2. We move up 2 units each time we move to the right 1 unit along the diagonal line.

Then you should simplify your radical,
there are 3 groups of 2 in the x variables and 2 groups of 2 in the y variables, as a result, the x and y go outside the square root, and one y variable remains in the root (as there wasn't enough y's to make another group of 2) this should be over 5

Find the dimensions of a rectangle with an area of 100 square feet that has the minimum perimeter.
Answers
The side length of the square with an area of 100 ft² is √(100 ft²) = 10 ft.
The rectangle with the minimum perimeter for an area of 100 ft² is 10 ft by 10 ft.
The rectangle with an area of 100 square feet that has the minimum perimeter is a square with sides of 10 feet each.
Explanation:To find the dimensions of a rectangle with a particular area that has the minimum perimeter, the rectangle should be a square. This is because squares minimize perimeter for a fixed area.
Given the area of the rectangle (square in this case), which is 100 square feet, the sides would be the square root of the area. Therefore, in this case, the length and the width of the rectangle (also known as the dimensions) are both √100 = 10 feet.Hence, the rectangle with an area of 100 square feet and minimum perimeter is a square with side lengths of 10 feet.
