The required area of the rectangle with dimensions 13 yards long and 23 yards wide is 299 square yards.
How to calculate the area of the rectangle?In order to evaluate the area of the rectangle we must know the length and width of the rectangle and put this measure of length and width of the rectangle in the formula of area,
Area of the rectangle = length × width
Here,
From the question,
we have length = 23 yard and width = 13 yards
Area of the rectangle = 23 × 13
= 299 square yards
Thus, the required area of the rectangle with dimensions 13 yards long and 23 yards wide is 299 square yards.

When simplifying an expression with a negative exponent, you take a positive version of the exponent, in this case that would be 2, and apply that to the base.
After doing that, we have 9.
The next step is to put one over that number.
In this case, now after doing that the answer is [tex] \frac{1}{9} [/tex].

This cylindrical fish tank has a height of 36 inches and a diameter of 30 inches. What is the volume of the fish tank?
Answers
area of cross-section x the height.
First lets work out the area of the cross-section. Since the cross-section is a circle, we use the formula π x r²
Halve the the diameter to get the radius, so we can use the formula:
30 / 2 =15
Area of cross-section
π x 15² = 706.8583471 inches²
Now that we know the area of the cross-section, we multiply this by the height to get the volume.
706.8583471 x 36 = 25446.90049
= 25446.90 (2dp)
So the volume of the cylindrical fish tank is 25446.90
The volume of the cylindrical fish tank is 25446.90 inches cube.
What is the volume of a right circular cylinder?Suppose that the radius of considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
The formula for the volume of a cylinder is:
The area of cross-section x the height.
Since the cross-section is a circle, we use the formula π x r²
Radius= 30 / 2 =15
Thus, Area of cross-section
π x 15² = 706.8583471 inches²
Now that we know the area of the cross-section,
706.8583471 x 36 = 25446.90049
= 25446.90 (2dp)
So. the volume is 25446.90

y= 2.75x
y= 3.05x- 0.6
y= 3.25x- 1
y= 9.75x- 14
Answers
Answer:
[tex]y=3.25x-1[/tex]
Step-by-step explanation:
step 1
Find the slope
we have the points
(2,5.5) and (5,15.25)
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
substitute
[tex]m=\frac{15.25-5.5}{5-2}[/tex]
[tex]m=\frac{9.75}{3}=3.25[/tex]
step 2
Find the equation of the line in slope intercept form
y=mx+b
we have
[tex]m=3.25\\point\ (2,5.5)[/tex]
substitute
[tex]5.5=3.25(2)+b[/tex]
solve for b
[tex]b=-6.5+5.5=-1[/tex]
therefore
[tex]y=3.25x-1[/tex]

In triangle XYZ, the length of side XY is 29 mm and the length of side YZ is 43 mm. Which of the following could be the length of side XZ?
Answers
The possible length of side XZ could be 50 mm
Which could be the length of side XZ?
From the question, we have the following parameters that can be used in our computation:
The length of side XY = 29 mmThe length of side YZ = 43 mmUsing the triangle inequality theorem, we have
Smallest length of XZ = 43 - 29
Smallest length of XZ = 14
Largest length of XZ = 43 + 29
Largest length of XZ = 72
So, we have
Range: 14 < x < 17
This means that the length of side XZ could be 50 mm because 50 is in the range 14 < x < 17

On average, 75% of the days in Henderson county are sunny, with little or no cloud cover. Describe a model that you could use to find experimental probability of sunny days each day for a week in Henderson county.
Answers
You could place 3 red marble and 1 blue marble in a bag. The probability of drawing a red marble would be 3/4, which is 75%; this means red marbles would be sunny days and blue marbles would be cloudy days.
Each draw out of the bag would represent one day of the week. Draw a marble 7 times, replacing it after each draw. This would represent the weather for the days of the week.
amy has 30 grams of flour. she puts 4 grams of flour in each pot of chowder that she make. she puts 5 grams of flour in each pot of potato soup that she makes. she makes 4 pots of chowder. does amy have enough flour left over to makes 3 pots of potato soup.
Answers
After using 16 grams of flour to make 4 pots of chowder, Amy has only 14 grams of flour left, which is not enough to make 3 pots of potato soup, each requiring 5 grams of flour.
To solve this problem, we need to calculate the total amount of flour Amy uses for the chowder. Since she makes 4 pots of chowder, she would need:
4 pots × 4 grams/pot = 16 grams of flour
After making the chowder, Amy would have 30 grams - 16 grams = 14 grams of flour left.
Amy wants to make 3 pots of potato soup, and each pot requires 5 grams of flour. Therefore, she would need:
3 pots × 5 grams/pot = 15 grams of flour for the potato soup
Since Amy has only 14 grams of flour remaining, she does not have enough flour to make 3 pots of potato soup.

Terrance has one fewer sibling than Casey. Kolbie has three more siblings than Terrance
Answers
Final answer:
By setting up simple equations based on the given statements, we can determine the relative number of siblings that Terrance, Casey, and Kolbie have.
Explanation:
Based on the provided statements, we can set up a system of simple algebraic equations to solve for the number of siblings each person has. Let's assume Casey has C siblings. According to the given information:
Terrance has one fewer sibling than Casey, which can be represented as T = C - 1.
Kolbie has three more siblings than Terrance, which can be represented as K = T + 3.
Therefore, Kolbie's equation becomes K = (C - 1) + 3 or K = C + 2 after simplifying. Through these relationships, we can understand the relative number of siblings each individual has.

The ordered pairs (1, 3), (2, 6), (3, 9), (4, 12) and (5, 15) represent a function. What is a rule that represents this function? a: y=x^3 b: y= 3^x c: y=3x d: y= x+3

.. a. 2^3 = 8 ≠ 6
.. b. 3^2 = 9 ≠ 6
.. c. 3*2 = 6

Justification:
All the ordered pairs meet that the second number of the pair equal 3 times the first number of the pair:
Here is the proof:
Pair first number times 3 second number of the pair
(1, 3) 3 * 1 = 3 3 => check
(2,6) 2 * 3 = 6 6 => check
(3,9) 3 * 3 = 9 9 => check
