Answer:

90 bags of sand

Step-by-step explanation:

9 feet × 1.5 = 13.5

12 feet × 1.5 = 18

Large pit area= 13.5 × 18 = 243ft squared

The small pit area=9 × 12 = 108ft squared

243 / 108 = 2.25 times larger

This means the large pit needs 2.25 times more sand.

40 × 2.25 = 90 bags of sand

Answer: y=0.074x+50.48

Step-by-step explanation:

The solution is : B. y = 0.097x + 11.142

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

here, we have,

In order to find the best equation to descibe the housing price, we have to calculate the slope of the line  first.

The equation of the line can be written as

y = mx + q

where m is the slope and q the y-intercept.

In order to have the most accurate estimate for the slope, we use the first point and the last point, that are:

(1900, 196)

and

(2200, 225)

The slope of the line is calculated as:

m = y2-y1/x2-x2 = 0.097

So, the slope of the line is 0.097.

Therefore, the correct option is the only one having a slope of 0.097, which is:

B. y = 0.097x + 11.142

Step-by-step explanation:

A fictional account offers benefits such as readers connecting emotionally with characters, like understanding George Washington's feelings, and provides immersive details on what experiencing historical events may have felt like, unlike nonfiction accounts which focus on factual precision.

A fictional account like the one in An American Plague by Jim Murphy offers two main benefits that a nonfictional account may not typically provide. First, it includes detailed characterization, which allows readers to connect with the characters on an emotional level. In this case, it's the portrayal of George Washington's feelings and his impatience as he left the city of Philadelphia. Second, a fictional account can offer vivid, imaginative details of what it was like to experience the event, thus bringing history to life in a way that purely factual retellings may not.

While nonfiction focuses on presenting the facts as accurately as possible, fiction can delve into the personal experiences and emotional journeys of historical figures, providing a different layer of understanding.

Answer:

Step-by-step explanation:

To figure out whether a triangle is a right triangle using only the side lengths, you can use the Pythagorean theorem:

a^2 + b^2 = c^2

1.5^2 + 2^2 = 3^2

2.25 + 4 = 9

Since this equation isn't true, these numbers cannot be the side lengths of a right triangle.

After applying the Pythagorean theorem to the triangle with sides 1.5 cm, 2 cm, and 3 cm, it is determined that the triangle is not a right triangle because the squares of the shorter sides do not sum up to the square of the longest side.

To determine if a triangle with sides measuring 1.5 cm, 2 cm, and 3 cm is a right triangle, we can apply the Pythagorean theorem. The theorem states that for any right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). In mathematical terms, this is expressed as c² = a² + b².

Let's check if our triangle meets this condition:

Since 6.25 cm² does not equal 9 cm², the sides do not satisfy the Pythagorean theorem, so the triangle is not a right triangle.

To divide 530 by 34, divide the quotient and the remainder. The whole number part of the quotient is 14 and the remainder is 54.

To divide 530 by 34, we start by determining how many times 34 can fit into 530. We find that 34 can fit into 530 fourteen times. So, the whole number in the answer is 14. Now we calculate the remainder by subtracting 14 times 34 from 530. The remainder is 530 - (14 * 34) = 530 - 476 = 54.

Therefore, the answer to 530 divided by 34 is 14 with a remainder of 54.

Answer:

r ≈ 6.71

Step-by-step explanation:

The distance from the centre of the circle to a point on it is the radius.

Calculate the radius r using the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (8, 2) and (x₂, y₂ ) = (14, - 1)

r = [tex]\sqrt{(14-8)^2+(-1-2)^2}[/tex]

  = [tex]\sqrt{6^2+(-3)^2}[/tex]

  = [tex]\sqrt{36+9}[/tex]

  = [tex]\sqrt{45}[/tex] ≈ 6.71 ( to 2 dec. places )

Final answer:

The radius of the circle with the center at (8, 2) and a point on the circle at (14, -1) is 6.71 units, after rounding to two decimal places.

Explanation:

To find the radius of a circle with a given center and point on the circle, we need to calculate the distance between these two points. This distance represents the radius. The center of the circle is at (8, 2) and the point on the circle is at (14, -1).

Using the distance formula, which is d = √((x_2 - x_1)^2 + (y_2 - y_1)^2), where (x_1, y_1) is the first point and (x_2, y_2) is the second point:

[tex]d = √((14 - 8)^2 + (-1 - 2)^2) = √((6)^2 + (-3)^2) = √(36 + 9) = √45[/tex]

When using a calculator that has an eight-digit output, √45 is approximately 6.70820393. However, if we are to report the answer with only two decimal places, we get the radius as 6.71 units.

It's important to note that significant figures play a role in determining the precision of our result. Even though the calculator can give us many decimal places, we often round the number to either preserve significant figures or because the extra precision is not materially important for estimation purposes. In this case, the radius to two decimal places is 6.71, despite the calculator's eight-digit output.

Answer:

Both the claims by the companies are not possible.

Step-by-step explanation:

Equations modeling number of employees 'y' after 'x' years of the start are,

For company R: y = 3x +24

For company T: y = 4x + 10

If Company R states that this year they have 42 employees,

42 = 3x + 24

3x = 42 - 24

x = [tex]\frac{18}{3}[/tex]

x = 6 years

So company has completed 6 years this year.

Now we put x = 6 years in the equation for company T.

y = (4×6) + 10

y = 24 + 10

y = 34

Which doesn't match with the number of employees of the company R.

Therefore, claim of company R is not possible.

Company T stated that after 15 years they will have the same number of employees as company R.

For company T : y = 4(15) + 10

                           y = 70 employees

For company R : y = 3(15) + 10

                           y = 45 + 10

                          y = 55 employees

Therefore, claim of the company T is also not possible.

Given the equations that model the number of employees y, at these companies x years after the companies began expressed as:

Company R: y = 3x + 24

Company T: y= 4x + 10

If both companies has the same number of employees, then;

3x + 24 = 4x + 10

3x - 4x = 10 - 24

-x = -14

x = 14

Since 14 ≠ 42 that company R claimed, hence the company does not have the same number of employees as company T has this year.

Functions and values

Given the equations that model the number of employees y, at these companies x years after the companies began expressed as:

Company R: y = 3x + 24

Company T: y= 4x + 10

If both companies has the same number of employees, then;

3x + 24 = 4x + 10

3x - 4x = 10 - 24

-x = -14

x = 14

Since 14 ≠ 42 that company R claimed, hence the company does not have the same number of employees as company T has this year.

Since 14 ≠ 15 that company T also claimed, hence the company does not have the same number of employees as company T has this year.

Answer:

Quadrant 1

Step-by-step explanation:

The terminal side of the angle whose measure is 40° falls in quadrant I.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

To determine the quadrant in which the terminal side of an angle falls, we need to look at the direction in which the terminal side moves from the origin.

If the terminal side moves to the right of the origin, it is in quadrant I or IV; if it moves to the left of the origin, it is in quadrant II or III.

The angle whose measure is 40° starts on the positive x-axis and moves in a counterclockwise direction.

Since 40° is less than 90° the angle will move less than 90° counterclockwise from the x-axis.

The terminal side of the angle will fall in quadrant I, which is the quadrant that lies to the right of the positive x-axis and above the positive y-axis.

Hence, the terminal side of the angle whose measure is 40° falls in quadrant I.

Answer:

20.58 inches

Step-by-step explanation:

As the variable x represents the number of times the figure is enlarged, to find the length of the image after it has been enlarged 3 times, we just need to use the function f(x) with the value of x = 3:

f(x) = 3 * (1.9)^x

f(3) = 3 * (1.9)^3

f(3) = 3 * 6.859

f(3) = 20.577 inches

Rounding to nearest hundredth, we have f(3) = 20.58 inches

So the length of the image after being enlarged 3 times is 20.58 inches

Final answer:

Cross sections of a square pyramid can include a trapezoid, a triangle, or a square. A circle or a pentagon are not possible shapes for these cross sections because they don't align with the pyramid's geometric structure.

Explanation:

The cross section of a square pyramid could be either a trapezoid, a triangle, or a square, depending on the plane's angle relative to the pyramid's base and sides. A circle or a pentagon cannot be cross sections of a square pyramid since they do not conform to the sides or base of a square pyramid.

A trapezoid cross-section can be obtained if the cutting plane is parallel to one base edge and intersects the other three edges of the pyramid. A triangle appears when the cutting plane passes through one vertex and cuts through the base, creating a cross section congruent to the faces of the pyramid. Lastly, a square section results when the cutting plane is parallel to the base and slices through the pyramid.
