Answer:

251 cm2

Step-by-step explanation:

The area of the circle whose radius is 40 cm is 5026 cm².

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

Given that the radius of the circle is 40cm. Therefore, the area of the circle will be,

Area of the circle = π × Radius²

                             = π× (40cm)²

                             = 1600π cm²

                             = 5026.54 cm²≈ 5026 cm²

Hence, the area of the circle is 5026 cm².

Step-by-step explanation:

The second graph is the only option that has equal increment by a common factor and it is the only graph that shows dilation.

A dilation in graph is also known as transformation.

The increased x-coordinates is known as horizontal dilation and the increased y-coordinate is known as vertical dilation.

The second graph is the only option that has equal increment by a common factor. Thus, the second graph shows dilation.

Step-by-step explanation:

Answer:

x = 17 and y = 8

Step-by-step explanation:

Since (6x + 3) and (8x - 31) are alternate interior angles, they are congruent.

Therefore, you can set them equal to each other and solve for x.

8x - 31 = 6x + 3

Combine like terms

2x = 34

Divide both sides by two

x = 17

Since (5y + 35) and (6x + 3) are consecutive interior angles, they add up to 180. Plug in 17 for x.

(5y + 35) + (6(17) + 3) = 180

Add like terms

5y + 140 = 180

5y = 40

y = 8

Answer:

not factorable

Step-by-step explanation

Answer:

May 06, 2018 · Real estate agents, car dealers, and pharmaceutical sales representatives earn commissions that are a percentage, or part, of sales. For example, a real estate agent might earn a portion of the selling price of a house that she helps a client purchase or sell. A car salesperson earns a portion of the selling price of an automobile that she sells.

$391 is earned by Mrs. Hollern for selling a necklace that  costs $4,600

Since a commission of 8.5%(0.085) is earned for each jewelry sold, hence the total commission (y) for selling x worth of jewelry is:

y = 0.085x

Hence for selling $4600, the commission earned is:

y = 0.085(4600)

y = 391

Hence $391 is earned by Mrs. Hollern for selling a necklace that  costs $4,600.

Answer:

2[tex]x^{2}[/tex]+x-28

Step-by-step explanation:

To solve binomial multiplication problems you can use the FOIL method. FOIL means first, outside, inside, last, which tells you what order to multiply the terms.

Multiply the first terms,

(2x-7)(x+4)

2[tex]x^{2}[/tex]

Then the outside terms,

(2x−7)(x+4)

8x

Next the inside terms,

(2x−7)(x+4)

-7x

Finally the last terms,

(2x−7)(x+4)

-28

To find the answer put all of the products together and simplify

2[tex]x^{2}[/tex]+8x-7x-28

Answer:

The events are not mutually exclusive.

Step-by-step explanation:

To determine that in the sample, are the events "believed the false headline" and "believed the true headline" mutually exclusive.

For two events, let say E₁ and E₂ are said to be mutually exclusive if they cannot both occur simultaneously. In set-theoretical notation, we can say that the two sets  E₁ and E₂ are disjoint. i.e.  E₁ ∩  E₂ = ∅ and the probability of them occurring at the same time is zero. i.e. Pr(  E₁ ∩  E₂ ) = 0

So, we can say;

Let P(true) = E₁  

P(false) = E₂

Thus; statistically:

Pr(  E₁ ∩  E₂ ) = Pr(E₁) + Pr(E₂) - P( E₁  ∪ E₂ )

So;

the probability of students that believed the true headline P(E₁) = 0.90

the probability of students that believed the false headline P(E₁) = 0.82

the probability of students that believed both P( E₁  ∪ E₂ ) = 0.75

∴

Pr(  E₁ ∩  E₂ ) = 0.90 + 0.82 - 0.75

Pr(  E₁ ∩  E₂ ) = 0.97

Thus, the events are not mutually exclusive.

Answer:

I took 5 minutes to think this through, hope I'm right cause been a long time since my brain killed me over this one question. I believe the answer to this is B, cause the students might of gotten two chances to get picked so I'll stick with B. So sorry if I'm wrong. 3 students 2 chances... yea it's B.

Answer:

31/3

Step-by-step explanation:

Multiply the denominator by the whole number 3×10=30

Then add the numerator 30+1=31

Hope this helps :)

The resulting improper fraction is 31 / 3.

To convert the mixed number 10 1 / 3 to an improper fraction, we first multiply the whole number (10) by the denominator of the fractional part (3), which gives us 30.

Then, we add the numerator of the fractional part (1) to get 31. We write the sum (31) as the numerator and keep the denominator (3) the same.

The resulting improper fraction is 31 / 3.

This means that 10 1/3 is equivalent to 31 / 3. The improper fraction emphasizes the total number of thirds, which is 31, without any whole number component.
