The remote interior angles of ∠1 are ∠2 and ∠6.

Corresponding angles in a triangle are those angles which are contained by a congruent pair of sides of two similar (or congruent) triangles.

The remote interior angles of ∠1 is determined by applying the principle of corresponding angles as shown below;

∠1 = ∠2 ( vertical opposite angles are equal )

∠1 = 180 - ∠5 ( corresponding angles  are equal )

180 - ∠5  = ∠ 6 ( vertical opposite angles are equal )

So we can conclude that, ∠1 = ∠6.

Answer:

-2(4x-5)

Step-by-step explanation:

Angle A coincides with angle E.

Angle B coincides with angle D.

Segment AC coincides with segment EF.

Segment AB coincides with segment ED.

Any geometric transformation of a euclidean space that keeps the euclidean distance between every pair of points is referred to as a rigid transformation.

Rotations, translations, and reflections are some examples of rigid transformations.

If we observe the given preimage and image we can conclude that the triangle is rotated about 90° counterclockwise.

∴ Points, A = E, B = D , C = F from this we can conclude that

The volume of pyramid is 3.5 cm³.

To find the volume of a pyramid with a square base, where the area of the base is 4.6 cm² and the height of the pyramid is 2.3 cm, we can use the following formula:

V = (1/3)B*h

Where V is the volume of the pyramid, B is the area of the base, and h is the height of the pyramid. Substitute the given values into the formula and solve:

V = (1/3)(4.6)(2.3)V = 3.53 cm³

Rounding to the nearest tenth of a cubic centimeter, the volume of the pyramid is 3.5 cm³. Therefore, the volume of pyramid is 3.5 cm³.

The standard deviation of the sample proportions (i.e., the standard error of the proportion) is 10.5.

The sample proportion is a random variable that can't be predicted with certainty because it fluctuates from sample to sample.

n = 525

Population Proportion(p) = 0.3

q = 1 - 0.3

q = 0.7

σ = √npq

σ = √(525 × 0.3 × 0.7)

σ = √110.25

σ = 10.5

So The standard deviation of the sample proportions = σ/n

The standard deviation of the sample proportions = 10.5/525

The standard deviation of the sample proportions = 0.02

To find the area of the polyhedron, we find the area of all faces of the polyhedron or the area covered by the net of the polyhedron

Considering all the options the lateral surface area is the area of the polyhedron without the area of the base. Therefore the surface area of a polyhedron can also be defined as the lateral surface area which is the area of every other face of the polyhedron except the base and then adding it to the area of one of the bases.

How do uv-induced dna lesions lead to mutation? drag the terms on the left to the appropriate blanks on the right to complete the sentences. not all terms will be used.

Answer:

When cells enter S phase with Ultraviolet-induced DNA lesions, the replicative DNA polymerases stall at the lesion.

Step-by-step explanation:

As a result of photosensitization, which causes the production of a free radical that interacts with DNA and oxidizes its bases, ultraviolet radiation causes oxygen-dependent DNA damage. Mutations occur when these oxidized bases don't pair properly during the replication process. The various types of DNA damage caused by ultraviolet radiation result in particular types of mutations and the development of skin cancer in people, frequently decades after initial exposure. There are noticeable UV-induced DNA lesions that are caused by various UV wavelengths.

The dividend on an 8 percent preferred stock that currently sells for $45 and has a face value of $50 per share is $4.00. The correct option is a.

The dividend on a preferred stock can be calculated using the formula: Dividend = Preferred Stock Price × Preferred Stock Dividend Rate. In this case, the preferred stock price is $45, and the preferred stock dividend rate is 8 percent. To calculate the dividend, we multiply $45 by 8 percent (0.08): $45 × 0.08 = $3.60.

However, it's important to note that preferred stock dividends are typically calculated based on the face value of the stock rather than the market price. The face value represents the original value of the stock and is often $100 or $50 per share. In this case, the face value is $50 per share. To adjust for the face value, we divide the calculated dividend by the market price and multiply it by the face value: ($3.60 ÷ $45) × $50 = $4.00. Therefore, the dividend on an 8 percent preferred stock that currently sells for $45 and has a face value of $50 per share is $4.00. The correct answer is A. $4.00.

You can carve out 150 cubes of side 0.1 m from the given block of wood.

To determine the number of cubes, we need to calculate the volume of the block and the volume of each cube.

The volume of the block is given by:

Volume = length × width × height

Volume = 75 cm × 50 cm × 40 cm

Converting the measurements to meters:

Volume = (75 cm / 100) m × (50 cm / 100) m × (40 cm / 100) m

Volume = 0.75 m × 0.5 m × 0.4 m

Volume = 0.15 m³

The volume of each cube is given by:

Volume of each cube = side³

Volume of each cube = (0.1 m)³

Volume of each cube = 0.001 m³

To find the number of cubes that can be carved out of the block, we divide the volume of the block by the volume of each cube:

Number of cubes = Volume of block / Volume of each cube

Number of cubes = 0.15 m³ / 0.001 m³

Number of cubes = 150

Therefore, you can carve out 150 cubes of side 0.1 m from the given block of wood.

Answer:

4 (3 y + 2 x)^2

Step-by-step explanation:

Factor the following:

36 y^2 + 48 x y + 16 x^2

Hint: | Factor out the greatest common divisor of the coefficients of 36 y^2 + 48 x y + 16 x^2.

Factor 4 out of 36 y^2 + 48 x y + 16 x^2:

4 (9 y^2 + 12 x y + 4 x^2)

Hint: | Factor by grouping.

The coefficient of x^2 is 4 and the coefficient of y^2 is 9. The product of 4 and 9 is 36. The factors of 36 which sum to 12 are 6 and 6. So 9 y^2 + 12 x y + 4 x^2 = 4 x^2 + 6 x y + 6 x y + 9 y^2 = 2 x (3 y + 2 x) + 3 y (3 y + 2 x):

4 2 x (3 y + 2 x) + 3 y (3 y + 2 x)

Hint: | Factor common terms from 2 x (3 y + 2 x) + 3 y (3 y + 2 x).

Factor 3 y + 2 x from 2 x (3 y + 2 x) + 3 y (3 y + 2 x):

4 (3 y + 2 x) (3 y + 2 x)

Hint: | Combine products of like terms.

Where

A spherical balloon has volume v and radius r. Its volume is reduced by a factor of 27.0.

Find the factor of its radius reduced!

The factor of its volume is

V₁/V₂ = 27

We use the formula for spherical volume to find r₁/r₂.

V₁/V₂ = (4/3 πr₁³)/(4/3 πr₂³)

27 = (r₁/r₂)³

r₁/r₂ = ∛27

r₁/r₂ = 3

Hence, the radius is reduced by a factor of 3.

When solving a system of linear equations by substitution, normally, we want to try to solve for the easiest one to get to or we choose a variable with unit coefficient.

A variable is a quantity that could change depending on the circumstances of an experiment or mathematical problem. Typically, a variable is denoted by a single letter. The general symbols for variables most frequently used are the letters x, y, and z.

A constant component of a word as opposed to a variable. a measurement of some property or characteristic using a number (as of a substance, device, or process)

Answer:

i. Yes, Nevan won.

ii. Nevan scored 7464 points.

Step-by-step explanation:

Given: each correct answer = 134 points

           each incorrect answer = -14 points

Since he got 58 questions correctly, then;

His number of points = 134 x 58

                                   = 7772 points

Also, he got 22 incorrect questions, then;

His number of points = -14 x 22

                                   = -308

Nevan's total points = 7772 + (-308)

                                 = 7772 - 308

                                 = 7464

Nevan scored 7464 points.
