The correct option is that in science, a theory encompasses many hypotheses.

In science, a theory is a well-established explanation that is supported by scientific evidence and is extensively tested through experimentation and observation.

It's a big idea that includes several connected hypothese that have been thoroughly investigated and found to be true. A theory that hasn't been put to the test is called a hypothesis.

A hypothesis is a proposed explanation that is subject to further testing. It's an untested hypothesis that hasn't yet undergone experimental validation. Theories are the result of a drawn-out and labor-intensive process of experimentation and observation.

They can never be established as an absolute answer to a scientific problem. Instead, they lay the groundwork for additional investigation and experimentation in that field of study.

The volume of the rectangular prism is 144 cubic inches.

The volume of a rectangular prism is calculated by multiplying its length, width, and height. In this case, the given dimensions are 3 inches by 12 inches by 4 inches.

To find the volume, we multiply the length (3 inches) by the width (12 inches) and then multiply the result by the height (4 inches):

Volume = 3 inches × 12 inches × 4 inches = 144 cubic inches.

This means that the prism can hold 144 cubic inches of space or fill a container with a capacity of 144 cubic inches.

The volume of an object is a measure of the amount of three-dimensional space it occupies. In this case, the rectangular prism has a length of 3 inches, a width of 12 inches, and a height of 4 inches. By multiplying these dimensions together, we determine that the volume of the prism is 144 cubic inches.

The answer is 23/40

To simplify this expression, we need to find a common denominator for each pair of fractions that are being added or subtracted.

 
The common denominator for 1/4 and 1/5 is 20, so we can rewrite 1/4 as 5/20 and 1/5 as 4/20. Then, we can subtract these fractions to get 1/20.

 
The common denominator for -3/4 and 1/8 is 8, so we can rewrite -3/4 as -6/8. Then, we can add these fractions to get -5/8.

 
Now, we can combine the two simplified fractions by finding a common denominator of 40. We can do this by multiplying 20 and 8, which gives us 160.

Then, we can rewrite 1/20 as 2/40 and -5/8 as -25/40. Adding these fractions together gives us:

2/40 - 25/40 = -23/40.

The absolute value of any number is always positive so it becomes 23/40.

The simplified version of (1/4 - 1/5) + (-3/4 + 1/8) is 23/40.

Answer:

126.5 or 126 and 1/2 (one half)

Step-by-step explanation:

To find out how much that yearly salary is in weeks, we can take the number and divide by 52, because there are 52 weeks in the year.

54,262/52 = 1043 and 1/2 or 1043.5

Now, we must do 26 * 45 because you are working for 45 hours, and making $26 an hour.

and that number for 26 * 45 is 1170.

Now to find how much more you make from taking the hourly job over the salary job, you need to find the difference.

To do that, you would subtract 1170 and 1043.5 or 1043 and 1/2.

That is 126.5 or 126 and 1/2 (one half)

1. Angles BAP and CAP are congruent by the definition of the angle bisector theorem.

2. Segment AP is congruent to itself by the reflexive property.

The angle bisector of a triangle divides a triangle into two parts, from an angle, and the angle is divided into two equal parts.

The bisected angle in this problem is given as follows:

Angle A.

The two new angles are given as follows:

<BAP and <CAP.

Hence they are congruent by the definition of the angle bisector theorem, and congruent is the word that completes the blank for item 1.

For item 2, the reflexive property is the property that states that a segment is always congruent to itself. Hence the reflexive property is the work that completes the blank for item 2.

The cone cup can hold 6.14 cubic inches of water.

A volume refers to the space occupied within the boundaries of an object in three-dimensional space.

To get volume of the cone cup, we will use formula for the volume of a cone \(V = (1/3)\pi r^2h\) where r is the radius of the base and h is the height.

Given:

Diameter (d) = 2.5 inches

Radius (r) = d/2 = 2.5/2 = 1.25 inches

Height (h) = 3.75 inches

Volume (V) = (1/3)π(1.25)²(3.75)

= (1/3)π(1.5625)(3.75)

= 6.13592315154

= 6.14 cubic inches.

The volume of the cube is 125 times the original volume.

The volume of a cube is calculated by cubing the length of its side. Let's consider the original volume of the cube as V and the original length of each side as s.

The original volume V = s^3.

When each side of the cube is multiplied by 5, the new length of each side becomes 5s. Therefore, the new volume V' can be calculated as V' = (5s)^3 = 125s^3.

Comparing the new volume V' to the original volume V, we can see that V' is 125 times larger than V.

Therefore, the correct answer is F. The volume is 125 times the original volume.

In summary, when each side of a cube is multiplied by 5, the resulting volume is 125 times the original volume. This can be understood by considering the relationship between the volume of a cube and the length of its side, where the volume is proportional to the cube of the side length.

1. Hence, det(A1​) ≠ 0 so the system has a unique solution and k can take any value. False. 2. Therefore, M13​ = -12k2 - 9.True. 3. Therefore, S is a subspace of P2​.  True.4.  Hence, [a2 a] spans R2. True

Question 1: False. If the determinant of a matrix A, det(A) = 0, then the system has either no solutions or infinitely many solutions. Hence, det(A1​) ≠ 0 so the system has a unique solution and k can take any value.

Question 2: True. The matrix A is a 3 x 3 matrix. M13​ will be the determinant of the 2 x 2 matrix that is left when the first row and the third column are removed from A. It can be evaluated as M13​ = -12k2 - 9. When c11​ = 5, we have det(A) = 40k - 12. Now, det(A) = c11​M11​ - c12​M12​ + c13​M13​ = 5(2k-4) + 3(-3) + (-2)(-12k2-9) = 40k-12. Therefore, M13​ = -12k2 - 9.

Question 3: True. To show that the set S is a subspace of P2​, we need to check that it is closed under addition and scalar multiplication. Let p(t) = a1t2 + a2t + a3 and q(t) = b1t2 + b2t + b3 be any two polynomials in S and let c be any scalar in R. Then, r(t) = p(t) + q(t) = (a1+b1)t2 + (a2+b2)t + (a3+b3) is also in S since (a1+b1)t2 + (a2+b2)t + (a3+b3) + (a1+a2+a3) = a1t2 + a2t + a3 + b1t2 + b2t + b3 = p(t) + q(t). Similarly, cr(t) = c(a1t2 + a2t + a3) = (ca1)t2 + (ca2)t + (ca3) is also in S since (ca1)t2 + (ca2)t + (ca3) + a1+a2+a3 = a1t2 + a2t + a3. Therefore, S is a subspace of P2​.

Question 4: True. The set of all vectors [a2 a] where a, b ∈ R spans R2. Let [x y] be any vector in R2. Then, [x y] = (x/2)[2 0] + (y/2)[0 1] + (x/2 - y/2)[1 1]. Therefore, [x y] is a linear combination of [a2 a]. Hence, [a2 a] spans R2.
