Step-by-step explanation:

Factor the following integer:

54

Hint: | Is 54 divisible by 2?

The last digit of 54 is 4, which means it is even. Therefore 54 is divisible by 2:

54 = 2 27:

54 = 2×27

Hint: | Now try to factor 27. Is 27 divisible by 2?

27 is not divisible by 2 since 27 is odd and 2 is even:

54 = 2×27 (27 is not divisible by 2)

Hint: | Is 27 divisible by 3?

The sum of the digits of 27 is 2 + 7 = 9, which is divisible by 3. This means 27 is divisible by 3:

27 = 3 9:

54 = 2×3×9 (9 is not divisible by 2 since 27 is not)

Hint: | Now try to factor 9. Is 9 divisible by 3?

9 = 3 3, which means 9 is divisible by 3:

9 = 3 3:

54 = 2×3×3×3 (3 is not divisible by 2 since 9 is not)

Hint: | Now try to factor 3. Is 3 prime?

No primes less than 3 divide into it. Therefore 3 is prime:

54 = 2×3×3×3

Hint: | Express 54 as a product of prime powers.

Answer:

Step-by-step explanation:

To write the ratio of baking soda to salt, we need to compare the amount of baking soda to the amount of salt in the recipe.

The recipe uses 3/4 teaspoon of baking soda and 3 teaspoons of salt, so the ratio of baking soda to salt is:

3/4 : 3

To simplify this ratio, we can divide both numbers by the greatest common factor (GCF) of 3 and 4, which is 1.

3/4 divided by 1 = 3/4

3 divided by 1 = 3

So the simplified ratio of baking soda to salt is:

3/4 : 3 = 3: 12

To find the value of the ratio, we can divide both the numerator and denominator by 3:

3/3 : 12/3 = 1: 4

Therefore, the value of the ratio of baking soda to salt is 1:4.

376.52 is the volume of the composite figure.

Step-by-step explanation:

Let's break this into two shapes.

A rectangular prism and a hemisphere

Volume Formula for rectangular prism: l • h • w

Volume Formula for hemisphere: (2/3)πr^3

l • h • w

10 • 4 • 8

40 • 8

320

Rectangular Prism: 320

(2/3)πr^3

2/3(3)^3

2/3(3.14)(27)

2.09333333333(27)

56.52

Hemisphere: 56.52

320 + 56.52 = 376.52

The volume of the composite figure is 376.52  \(cm^{3}\).

The total space occupied by a hemisphere in a 3-dimensional region is called its volume. Geometrically a hemisphere is an exact half of a sphere.

Volume of hemisphere = \(\frac{2}{3} \pi r^{3}\)

The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height.

Volume of cuboid = Length × Width × Height

Given

Radius of hemisphere r = 3

Volume of hemisphere = \(\frac{2}{3} \pi r^{3}\)

Volume of hemisphere V1= \(\frac{2}{3} \pi r^{3}\)

= \(\frac{2}{3} .(3.14).(3)^{3}\)

= 56.52 \(cm^{3}\)

Volume of cuboid V2 = Length × Width × Height

= 10 × 8 × 4

= 320 \(cm^{3}\)

The volume of the composite figure V = V1 + V2

V =  56.52 +  320

V = 376.52  \(cm^{3}\)

Hence, the volume of the composite figure is 376.52  \(cm^{3}\).

A scientific hypothesis is a proposed explanation or prediction based on limited evidence or prior knowledge, which is subject to further investigation and testing.

A guess is a speculative, unsupported statement without any logical basis, whereas a hypothesis is an educated assumption derived from existing knowledge, observations, or theories. Unlike a guess, a hypothesis is testable and can be supported or refuted by evidence gathered through scientific methods.

Scientists need a hypothesis to provide a framework for their research and guide their investigations. It helps them define the specific question they want to answer and provides a starting point for designing experiments or making observations. By formulating a hypothesis, scientists can systematically evaluate and analyze data, ultimately leading to a deeper understanding of the phenomenon under investigation.

There are indeed scientific hypotheses that cannot be directly tested or proven due to practical or ethical constraints. For example, hypotheses related to historical events that occurred in the distant past may not have accessible evidence for direct testing. Additionally, some questions related to consciousness, subjective experiences, or philosophical concepts may lie beyond the scope of scientific inquiry, as they may not be objectively measurable or observable.

While science has its limitations, it is a powerful tool for investigating and understanding the natural world. However, there are questions that fall outside the realm of scientific inquiry and require other methods of investigation, such as philosophical or ethical considerations.

To estimate the divergence of the vector field vector f at the point (2, 7, 9), we can use the Divergence Theorem. The theorem states that the flux of a vector field through a closed surface is equal to the volume integral of the divergence of the vector field over the enclosed volume.

In this case, we are given the flux of vector f out of a small cube of side 0.01 centered around the point (2, 7, 9) as 0.003. This means that the flux through the cube's six faces is 0.003. Since the cube is small, we can approximate it as a point source, and the flux through the cube is proportional to the divergence of the vector field at that point.

Therefore, we can estimate the divergence of vector f at (2, 7, 9) as 0.003 divided by the volume of the cube. The volume of the cube is (0.01)^3 = 0.000001, so the estimated divergence is 3. This means that the vector field is spreading out from the point (2, 7, 9) with a magnitude of 3 units per unit volume.

Note that this is only an estimate since the cube is small, and the divergence may vary significantly over larger volumes. However, this calculation gives us a rough idea of the divergence at the point of interest.

Answer:

41° and 49°

Step-by-step explanation:

Two angles are said to be complements if the sum of their measures is 90 degrees. Since one angle is eight more than twice the other, we can set up the following equation to represent the situation:

2x + 8 = 90

Solving for x, we get:

2x = 82

 x = 41

Since the two angles are complements, their measures must add up to 90 degrees. Therefore, the measure of the other angle is 90 - 41 = 49 degrees.

Therefore, the two angles have measures of 41 and 49 degrees.

The graph that represents the given inequalities is required.

The required graph is attached.

The inequalities are

\(x^2+9y^2<81\)

\(y^2+2<x\)

Converting to general forms

Ellipse

\(\dfrac{x^2}{9^2}+\dfrac{9y^2}{9^2}<1\\\Rightarrow \dfrac{x^2}{9^2}+\dfrac{y^2}{3^2}<1\)

So,

\(a=\pm9\)

\(b=\pm3\)

The vertices of the major axes are \((9,0)\) and \((-9,0)\)

The vertices of minor axes are \((0,3)\) and \((0,-3)\)

The center lies on the origin.

Since, the sign of the inequality is \(<\) the shaded region will be inside the ellipse excluding the ellipse.

Parabola

\(x>1(y-0)^2+2\)

So,

Vertex of parabola = \((2,0)\)

If the shape is made up of one half-circle attached to an equilateral triangle with side lengths 20 inches then, the perimeter of the shape is 91.4 inches.

To find the perimeter of the shape, we need to know the length of the curved boundary (the circumference of the half-circle) and the length of the straight boundary (the perimeter of the equilateral triangle).

The radius of the half-circle is half the length of the side of the equilateral triangle, which is 10 inches. Therefore, the circumference of the half-circle is:

C = πr = π(10) = 31.4 inches.

The perimeter of the equilateral triangle is 3 times the length of one side, which is 20 inches. Therefore, the perimeter of the triangle is:

P = 3s = 3(20) = 60 inches

Finally, the perimeter of the entire shape is the sum of the lengths of the curved and straight boundaries:

Perimeter = C + P = 31.4 + 60 = 91.4 inches.

The measure of ∠PQR is approximately 101°.

To find the measure of angle ∠PQR, we can set up an equation using the information given.

From the problem, we know that m∠PQR = (12x - 2)° and mPR⌢ = (20x - 10)°.

Since ∠PQR is an inscribed angle and PR is a tangent, we can apply the inscribed angle.

According to the measure of an inscribed angle is half the measure of its intercepted arc.

The intercepted arc in this case is the major arc formed by points P and R.

Since Y lies on this arc, we can say that the intercepted arc measures 360° - mPR⌢.

We have the equation:

m∠PQR = 0.5 × (360° - mPR⌢)

Plugging in the given values, we get:

(12x - 2)° = 0.5 × (360° - (20x - 10)°)

Simplifying the equation:

12x - 2 = 0.5 × (360 - 20x + 10)

12x - 2 = 0.5 × (370 - 20x)

12x - 2 = 185 - 10x

22x = 187

x ≈ 8.5

Now we can find the measure of ∠PQR by substituting the value of x back into the expression:

m∠PQR = (12x - 2)°

= (12 × 8.5 - 2)°

≈ 101°

The correlation coefficient (r) measures the strength and direction of the linear relationship between two variables. The value of r ranges from -1 to +1, where a value of -1 indicates a perfect negative correlation, +1 indicates a perfect positive correlation, and 0 indicates no correlation.

The correlation coefficient's sign will not change when the order of the variables in a correlation study is changed, but the coefficient's numerical value might. This is due to the symmetry of the correlation coefficient with regard to the two variables under comparison.

For instance, if you calculate the correlation coefficient between X and Y and the result is r = 0.7, it indicates that Y tends to rise as X does. The correlation coefficient between the variables Y and X will have the same sign (+ or -) but a different numerical value if the variables are computed in a different order.
