He placed the decimal point incorrectly when multiplying. He wrote the rate incorrectly. He did not make an error.

Answer/Step-by-step explanation:

The conditions where we are allowed to subtract or add radicals together is when the radicands, which is the number inside the radical, of both radicals are the same. And also, when they both have the same indices, that is, for example, they have the same root.

Take for example the following radical expression:

[tex]4\sqrt{2} + 3\sqrt{2}[/tex]

Both radicals, [tex]4\sqrt{2} and 3\sqrt{2}[/tex], have the same radicand, [tex]\sqrt{2}[/tex] , and also the same index of square root.

Therefore, they are regarded as like terms, and can be added or subtracted together.

Thus,

[tex]4\sqrt{2} + 3\sqrt{2} = 7\sqrt{2}[/tex]

Answer:

1) TRIANGULAR PRISM

3) d. 144 cm3

Step-by-step explanation:

1) When figuring out what shape a net is, look at the two shapes that are different. In this case, its the triangles. Then take a look at the other shapes. If it has a rectangle base then you know its a prism. If it has a different shpes base then you know its pyramid. Now just combine the two key words you found. Triangle + Prism = Triangular Prism

2) A solid is something that is firm and stable. So it is not a liquid or solid. Pretty much everything that you listed is a solid.

3) The formula for finding the volume of a triangular prism is bxhxl divided by 2. So it would be 8x3x12= 288 divided by 2= 144 cm3

Answer:

The beam will bend by 50 mm with a mass of 100kg?

Step-by-step explanation:

The first step in solving the problem of direct variation is setting up the relation mathematically.

We can do this as follows:

The bending of the beam varies directly as its mass.

[tex]20 \alpha 40kg[/tex]

[tex]\alpha[/tex] here is the symbol representing direct variation. To remove this and replace it with an equality sign, we have to introduce a constant of proportionality, k

[tex]20 = k \times 40[/tex]

k = 20 /40 = 0.5

We can now use this to find the distance the beam will bend with a mass of 100kg?

This will be

[tex]Bending = 0.5 \times 100 =50mm[/tex]

There fore, the beam will bend by 50 mm with a mass of 100kg?

Step-by-step explanation:

Each bar represents a range in area. The first bar represents the number of houses with an area of more than 50 but less than 100. It's height is 4, so there are 4 of those houses.

Detailed explanation:

The diagonals of the parallelogram must be measured in order to ascertain its name. Let's figure out these numbers:

The slope of the EF is equal to (y2 - y1) / (x2 - x1) = (-1 - (-4)) / (0 - (-2)) = 3 / 2.

Diagonal GH: [(x2 - x1)2 + (y2 - y1)2] is the length of the GH.

= √[(-5 - (-3))² + (-2 - 1)²]

= √[(-2)² + (-3)²]

= √[4 + 9] = √13

Slope of GH is equal to (y2 - y1)/(x2 - x1) = (-2 - 1)/(-5 - (-3)) = -3 / -2 = 3 / 2

Let's examine the outcomes now:

The parallelogram is a rhombus if the lengths of both diagonals are equal (EF = GH) and the slopes of both diagonals are equal (slope of EF = slope of GH).

In our case, EF = GH = √13, and the slopes of EF and GH are both 3/2. Therefore, the parallelogram is a rhombus.

Therefore, the correct answer is c) Rhombus.

For the first question, the most specific name for the parallelogram defined by the coordinates E, F, G, and H is d) Square because the lengths of the sides and the diagonals are equal.

For the second question, the statement that would prove the parallelogram PWRS is a rhombus is d) Length of QR and PS is 2.2 and Length of RS and QP is 2.2, as it shows that all sides of the parallelogram are congruent.

To determine the most specific name for the parallelogram defined by the given coordinates, we need to analyze the properties of the shape based on the lengths and slopes of its diagonals.

Let's analyze each option:

a) Rectangle: In a rectangle, opposite sides are parallel and equal in length.

Diagonals are also congruent.

To determine if the parallelogram is a rectangle, we need to find the lengths of the diagonals.

Using the distance formula, we find that the length of EF is approximately 4.47 units, while the length of GH is approximately 4.24 units.

Since the diagonals are not congruent, the parallelogram is not a rectangle.

b) Triangle: A triangle is a three-sided polygon, which is not applicable to the given parallelogram.

c) Rhombus: In a rhombus, all sides are congruent.

The diagonals of a rhombus are perpendicular bisectors of each other. To determine if the parallelogram is a rhombus, we need to compare the slopes of the diagonals.

The slope of EF is -3/2, while the slope of GH is -3/2.

Since the slopes are equal, and the lengths of the sides are not given, we cannot determine if the parallelogram is a rhombus solely based on the given information.

d) Square: A square is a special type of rectangle and rhombus, where all sides are congruent and all angles are right angles.

Since we cannot determine if the parallelogram is a rhombus, we cannot conclude that it is a square.

In conclusion, based on the given information, we cannot determine the most specific name for the parallelogram defined by the coordinates.

For the second question, to prove that the parallelogram PWRS is a rhombus, we would need to show that the lengths of the sides are congruent and that the diagonals are perpendicular bisectors of each other.

However, based on the given options, we do not have the required information to prove that PWRS is a rhombus.

Step-by-step explanation:

You add fractions to get this.

1 room/3 hours + 1 room / 2 hours = 1 room / x

0.33333333+0.5 = 1 room / x

0.83333333 = 1 / x    Multiply both sides by x

0.83333333x  = 1      Divide by 0.8333333

x = 1/0.833333

x = 1.2 hours or

x = 1 hour and 12 minutes  

Answer:

100

Step-by-step explanation:

If a number is divisible by 5, then the last digit is either 0 or 5.

Since all the digits are even, the last digit must be 0.

There are 4 options for the first digit (2, 4, 6, 8).

There are 5 options for the second digit (0, 2, 4, 6, 8).

There are 5 options for the third digit (0, 2, 4, 6, 8).

So the total number of numbers is:

4×5×5×1 = 100

Answer: (0.4016, 0.4984).

Step-by-step explanation:

Let p be the proportion of voters will vote for Candidate A for president.

Formula for confidence interval for proportion:

[tex]\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]

, here [tex]\hat{p}[/tex]= sample proportion

n= sample size.

z* =two-tailed critical z- value.

As per given, we have

n= 700

[tex]\hat{p}[/tex] = 0.45

Critical two-tailed z-value for 99% confidence interval = 2.576

Then, the required 99% confidence interval for p would be:

[tex]0.45\pm (2.576)\sqrt{\dfrac{0.45(1-0.45)}{700}}\\\\=0.45\pm(2.576)\sqrt{0.000353571428}\\\\=0.45\pm (2.576)(0.0188035)\\\\=0.45\pm0.04844\\\\=(0.45-0.048437,\ 0.45+0.048437)\\\\=(0.401563,\ 0.498437)\approx(0.4016,\ 0.4984)[/tex]

Hence, the required confidence interval (0.4016, 0.4984).

The lower quartile in A is 74

47 and 49 are the smallest consecutive numbers

The lower quartile in B is 48

Answer:

29

Step-by-step explanation:

To find the lower quartile of each you need to find the median to split them into 2 groups (upper and lower quartile).

Lower quartile of Set A: 73, 75, 79, 81, 84, 85

Lower quartile of Set B: 47, 49, 51, 51, 55, 56

Now you find the median of the 2

Set A: 80

Set B: 51

Lastly you subtract A & B and get 29

Answer:

45°

Step-by-step explanation:

The sum of a triangle's angles is 180°.

Let's take the triangle FIG and try to express its angles in function of x.

● < F :

< F +3x = 180 => <F = 180 -3x

● < G :

IK and GH are paralell. IG is crossing them.

x and G are interior alternate angles so they have the same size.

< G = x

● < I :

We khow that < F = 180 -3x and < G = x

< I = 180-(< F + < G )

< I = 180 - ( 180-3x +x)

< I = 180 -(180-2x)

< I = 180 -180 +2x

< I = 2x

■■■■■■■■■■■■■■■■■■■■■■■

< F = 180 -3x

< G = x

< I = 2x

< I + > I + x + 2x = 360

2x + 180-x +3x = 360

4x + 180 = 360

4x = 180

x = 45°

●●●●●●●●●●●●●●●●●●●●●●●

Let's verify :

< F = 180 - 3*45 = 45 °

<G = x = 45°

< I = 2x = 90°

90° +45°+45° = 180°

So it's true.

Step-by-step explanation:

y = 2x + 4 is linear -- any equation involving only first powers of x and y (and constants) is linear. You'll usually see linear equations in the forms y = mx + b, ax + by = c, or y - y1 = m(x - x1).

If you take any two points, find the slope of the line between them, and then plug in one point to solve for the constant term (like you did), you will get a linear equation through those points.
