Javier is constructing a door for his son's tree house. The dimensions of the rectangular door are 6a^2-a+2 feet and 3a^2+5 feet. He wants to cut out a square from the door to insert a glass panel, as per the diagram below. The glass panel will have a height of a -3 feet.After Javier removes the square for the glass panel, how much of the door will be made from wood?

Answers

Answer 1

The area of a figure is the amount of space the figure can occupy. [tex]18a^4 + 10[/tex] of the door will be made from the wood.

Given

[tex]Length = 6a^2 + 2[/tex]

[tex]Width = 3a^2 + 5[/tex]

First, calculate the area of the rectangular door

[tex]Area = Length \times Width[/tex]

[tex]Area =(6a^2 + 2) \times ( 3a^2 + 5)[/tex]

[tex]Area = 18a^4 + 6a^2 + 30a^2 + 10[/tex]

[tex]Area = 18a^4 + 36a^2 + 10[/tex]

Next, calculate the area of the glass panel

The dimension of the glass panel is not given, and the diagram is not attached. So, I will assume the dimension of the square glass panel is [tex]6a[/tex].

So, the area of the glass panel is:

[tex]Area = 6a \times 6a[/tex]

[tex]Area = 36a^2[/tex]

To calculate how much wood that will be needed for the rectangular door, we simply subtract the area of the glass panel from the area of the door

[tex]Wood = 18a^4 + 36a^2 + 10 - 36a^2[/tex]

Collect like terms

[tex]Wood = 18a^4 + 10 + 36a^2 - 36a^2[/tex]

[tex]Wood = 18a^4 + 10[/tex]

Considering the assumed value, [tex]18a^4 + 10[/tex] of the door will be made from the wood.

HELP FAST A vertical slice through a three-dimensional solid produces a two-dimensional shape. (shape is a triangle)

Answers

Answer:

the surface of "C" would be a triangle if sliced vertically

Step-by-step explanation:

If  vertical slice through a three-dimensional solid produces a two-dimensional shape is triangular prism, option C is correct.

What is Three dimensional shape?

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

If a vertical slice through a three-dimensional solid produces a two-dimensional shape which is a triangle, it means that the solid has a triangular cross-section.

In other words, the cross-section of the solid that is perpendicular to its base is in the shape of a triangle.

A triangular prism is a solid shape that has a triangular cross-section. If you were to take a vertical slice through the prism, the resulting two-dimensional shape would be a triangle.

Hence, if  vertical slice through a three-dimensional solid produces a two-dimensional shape is triangular prism

The manager of a theater wants to know whether majority of his patrons are adults or children. One day, 5400 tickets were sold and the receipts totaled $41,616. The adults admission is $9.50, and the children's admission is $6.50. How many adults patrons were there? ​

Answers

Answer:

2,172 adults

Step-by-step explanation:

Let adults = x

children = y

x + y = 5400

9.5x + 6.5y = 41,616

Let's use the elimination method to solve this.

Multiply the top equation by -6.5

(x + y = 5400)-6.5

-6.5x - 6.5y = -35100

This will allow us to eliminate the y and add up the other terms

9.5x + 6.5y = 41,616

-6.5x - 6.5y = -35100

3x = 6516

Divide both sides by the coefficient, 3, to isolate the variable, x

3x/3 = 6516/3

x = 2172

Answer:

d = 28.6 m

Step-by-step explanation:

Given:

vi = 22.4 m/s

vf = 0 m/s

t = 2.55 s

Find:

d = ??

d = (vi + vf)/2 *t

d = (22.4 m/s + 0 m/s)/2 *2.55 s

d = (11.2 m/s)*2.55 s

d = 28.6 m

Help with the length of the third side?

Answers

Answer:

C. c = 10

Step-by-step explanation:

You have to use the Pythagorean theorem:

c² = 6² + 8²

c² = 36 + 64

c² = 100

c = √100

c = 10

Answer:

c = 10

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

6^2 + 8^2 = c^2

36+64= c^2

100 = c^2

Take the square root of each side

sqrt(100) = sqrt(c^2)

10 -c

The freshman class is planning a picnic. The cost of a permit to use the park is
$250. To pay for the permit, there is a fee of $.75 for each freshman and $1.25 for
each guest who is not a freshman. Two hundred freshman plan to attend. How many
guests must attend in order to at least pay for the permit? Let g represent the number
of guest attending.

Answers

Answer:

80

Step-by-step explanation:

Permit : $250
Fee for freshies : $0.75
Fee for non-freshies: 1.25

If you have 200 freshman coming , you would multiply 0.75 X 200= $150

Now how many non-freshies need to show up to meet the $250 permit?

250(permit) - 150= $100

$100 divided by $1.25 = 80 non-freshies would need to show up , enabling to pay the full of the $250 permit fee
