The picture attached aside shows us a right-angled parallelepiped and the Euclidean geometry indicates that a plane is generated by three non-colinear points, that is, three points that cannot be contained by a line.

Therefore, coplanar points are points that can be contained by one and same plane. Parallelepipeds are solids with eight vertices and twelve sides, each of them corresponding to a plane.

In this problem we must determine what fourth point is contained by the same plane that comprises the other three. Now we show the corresponding answers:

The value of ∠ F L H  is 3x-6°

∠FLG and ∠FLH are adjacent angles with L being the common vertex  and both the angles form the ∠HLG

As ∠FLG is given as 14x + 5° and  ∠ H L G is given as 17 x − 1 °

We need to find the value of ∠ F L H

We can write that ∠FLG +∠FLH = ∠ H L G

by putting the values given

14 x + 5 ° + ∠ F L H  = 17 x − 1 °

∠ F L H = 17x-1 - (14x + 50

Here we got a linear equation in one variable and by solving the equation we will get the value of ∠ F L H

∠ F L H = 17x - 1 - 14x -5

∠ F L H  = 3x-6

Hence, the value of ∠ F L H  is 3x-6°

Cost of pen = 20x  when x< 10

                              and

                      =10x when x>10

Let the number of pens bought be x.

So the total pen cost is 20x when the number of the pen is less than 10.

Now let's take that the number of pens bought is more than 10

So the pen will cost a 50% discount  

    50% of 20x

  = 20/100 × 20x

  = 10x

So the cost of the pen will be 10x when the number of the pen is greater than 10.

From this, we get to know that

Cost of pen = 20x when x<10

                              and

                       = 10x when x>10

Answer:

(3x - 5)(x - 6).

Step-by-step explanation:

In order to factor this quadratic, we can use the method of grouping. First, we need to find two numbers that add up to 23 and multiply to 90. The two numbers 18 and 5 satisfy both of these conditions,

since 18 + 5= 23 and 18*5

We can then factor the quadratic as follows:

[tex]\sf 3x^2 - 23x +30[/tex]

we can write it as:

[tex] \sf 3x^2 -(18+5)x + 30 [/tex]

Opening bracket

[tex] \sf 3x^2 - 18x -5x +30  [/tex]

Taking common from each two terms

[tex] \sf 3x(x-6) -5(x-6)  [/tex]

Taking common and keeping remaining in bracket

[tex] \sf (x-6)(3x-5)  [/tex]

Therefore, the quadratic of [tex] \sf 3x^2 - 23x +30  [/tex] can be factored as (3x - 5)(x - 6).

The values of x and y in the lines are x = 13 and y = 54

From the question, we have the following parameters that can be used in our computation:

The lines m and n are parallel lines

This means that the following angles are congruent by the corresponding angle theorem

7x - 31 + 5x - 8 + 63 = 180

4y + 27 - 180 = 63  

Solving the equation 4y + 27 - 180 = 63  

We have the following representation

4y + 27 - 180 = 63  

Evaluate the like terms

4y = 216

Divide by 4

y = 54

Recall that

7x - 31 + 5x - 8 + 63 = 180

Evaluate the like terms

12x = 156

Divide by 12

x = 13

Hence, the values are x = 13 and y = 54

The circumference of the Canadian $1 coin is 83.21 mm

For given question,

We have been given the Canadian $1 coin has a diameter of 26.5 mm.

We need to find the circumference of the coin.

We know that circumference of a circle of radius r is,

c = 2πr

The Canadian $1 coin has a diameter of 26.5 mm.

So, the radius of the coin would be,

r = 26.5 /2

r = 13.25

Using the formula of circumference, the circumference of the coin would be,

⇒ c = 2πr

⇒ c = 2 × π × r

⇒ c = 2 × 3.14 × 13.25

⇒ c = 83.21 mm

Therefore, the circumference of the Canadian $1 coin is 83.21 mm

The ratio of blue hats to red hats IS 3:2 , the ratio of the blue hats all hats is 3:5 and If the store purchased 45 hats, 27 hats were blue

The ratio of blue hats to red hats is 9:6, which can be simplified to 3:2

Therefore the ratio of blue hats to red hats is 3: 2

The total number of hats is the summation of blue hats and red hats = 9+6= 15

So, The ratio of blue hats to all hats is 9:15, which can be simplified to 3:5

Therefore the ratio of blue hats to red hats is 3: 5

If the store purchased 45 hats, and we need to find out the number of blue hats

We have to assume the number of blue hats be x

Then the ratio becomes x: 45::3:5

We can also write this as

X= 3a and 45= 5a

The value of a comes out to be 9

So the number of blue hats purchased in the lot is 3a= 3 9 = 27

Step-by-step explanation:

Answer: 24x² + 20x + 4

Step-by-step explanation:

       Area of a rectangle can be found with A = L * W;

               A = L * W

               A = (8x + 4) * (3x + 1)

       Now we can use the "FOIL" method, which is used to multiply binomials.

[F] First ➜ 8x * 3x = 24x²

[O] Outside ➜ 8x * 1 = 8x

[I] Inside ➜ 4 * 3x = 12x

[L] Last ➜ 4 * 1 = 4

       Lastly, we add it all together for our final answer.

24x² + 8x + 12x + 4 = 24x² + 20x + 4

Answer:

24x^2+20x+4

Step-by-step explanation:

Area is length times width.

The length is (8x+4) and the width is (3x+1).

If we follow the formula for the area of a rectangle, then it would be

(8x+4)(3x+1).

Next, you would foil.

Take the first and multiply it by the second equation as follows

8x*3x+8x*1 which would give you

24x^2+8x

Then, you would take the second from the first equation and multiply it with the second equation as well.

4*3x+4*1 which would give you

12x+4

Combine all of it together

24x^2+8x+12x+4

Combine like terms

24x^2+20x+4

That's the area.

The equation that can be used to determine the cost of a bag of potatoes is $31.69 - $4.09 = 4x

The cost of a bag of potatoes is $6.90

From the question, we are to write and solve an equation that could be used to determine x, the cost of a bag of potatoes

From the given information,

Serenity buys milk and potatoes at the store and she pays a total of $31.69

and

She pays a total of $4.09 for the milk

Thus,

The amount she pays for potatoes is $31.69 - $4.09

Also, from the information,

"She buys 4 bags of potatoes that each cost the same amount"

If x represent the cost of a bag of potatoes, then we can write that

$31.69 - $4.09 = 4x

This is the equation that can be used to determine the cost of a bag of potatoes

Now,

Solve the equation for x

$31.69 - $4.09 = 4x

$27.60 = 4x

x = $27.60/4

x = $6.90

Hence, the cost of a bag of potatoes is $6.90

Answer:

a. 3 units

Step-by-step explanation:

The length of BC can be found in 3 main steps, namely the formation of equations, solving for x and substitution.

Let's rewrite the given lengths:

AB= 4x +1 -----(1)

BC= 2x -7 -----(2)

AC= 24 -----(3)

Form an equation which relates the 3 lengths:

Given that B is between A and C,

AC= AB +BC -----(4)

Substituting equations (1) to (3) to equation (4):

24= 4x +1 +2x -7

Simplify:

24= 6x -6

Add 6 to both sides:

6x= 24 +6

6x= 30

Divide both sides by 6:

x= 5

Substitute x= 5 into (2):

BC

= 2x -7

= 2(5) -7

= 10 -7

= 3 units

Thus, option a is correct.

According to the question, a region is bounded by semicircular arcs on the side of the squares. Therefore, the side of the square is the diameter of the circle.

And the side of the square is [tex]\frac{2}{\pi }[/tex].

Now, the radius of the semicircle is [tex]\frac{1}{2} \frac{2}{\pi } =\frac{1}{\pi }[/tex]

The length of the semicircular arc is equal to half the circumference of the corresponding circle.

Therefore, the length of the arc is [tex]\frac{1}{2} (2)(\pi)\frac{1}{\pi } =1[/tex]

Now, the desired parameters of the region made by these arcs is [tex](4)(1)=4[/tex]

The probability of drawing a red card, placing it back in the deck, and drawing another red card is 1/4.

According to the given question.

Total number of cards in a deck is 52.

As we know that total number of red cards in a well shuffled deck is 26.

Since, Eric first draws a red card, places it back in the deck, shuffles the deck, and then draws another card. Which means there is a replacement of cards.

So, the probability of drawing the first card is red = 26/52 = 1/2

And the probability of drawing the another card is red = 26/52 = 1/2

Therefore,

The probability of drawing a red card, placing it back in the deck, and drawing another red card

= 1/2  × 1/2

= 1/4

Hence, the probability of drawing a red card, placing it back in the deck, and drawing another red card is 1/4.
