What is the volume of a right triangular prism?

A right triangular prism is a 3-dimensional triangle with two congruent triangular faces and 3 rectangular faces that connect the triangular.

The volume of a right triangular prism = ( height × Base Area)

A. The length of the tent to the nearest foot, from the front to the back

= 15 + 6 + 15+ 6

= 42 ft

B. Given that the tent is in the shape of a triangular prism the volume of the prism will be given by:

The volume of a right triangular prism = ( height × Base Area)

height = √(36 - 9)

= √27

The volume of a right triangular prism = √27 × 157.2

= 816.83

wanting some extra help with factoring while knowing what method it would be like gcf or grouping etc

Answers

d) You have a difference of squares:

49y² - 9 = (7y)² - 3²

Recall the identity,

a² - b² = (a - b) (a + b)

So,

49y² - 9 = (7y - 3) (7y + 3)

e) Pull out the common factor 3 from each term:

3x² - 3x - 90 = 3 (x² - x - 30)

Now use the sum-product method. Notice that we can write 30 = 5 • 6, and 5 - 6 = 1, so

3x² - 3x - 90 = 3 (x + 5) (x - 6)

f) Same as in (e), use the sum-product method. Notice that 42 = 7 • 6, and -7 - 6 = -13, so

x² - 13x + 42 = (x - 7) (x - 6)

49y²-9(7y)²-3²(7y-3)(7y+3)

3x²-3x-903(x²-x-30)3(x-6)(x+5)

x²-13x+42x²-7x-6x+42(x-7)(x-6)

a cube shaped shed has a 6 foot high walls if all the shed's walls are painted not including the floor or ceiling how much area will be painted

Answers

answer:288
since it’s a cube , all side lengths will be equal- in this case , 6 feet.
to get the area of one wall , you do height x width- in this case 6x6.
that equals 36 , which is the area for 1 wall.
since they’re painting all 8 walls , you multiply 36x8
that gets you the answer 288 (feet squared)

Determine the center and radius: x2 + y2 - 10x + 8y -8 = 0

Answers

So our equation currently is ⇒ [tex]x^2+y^2-10x+8y-8 = 0[/tex]

Let's first move all the constant to one side and group 'like variables' together:

[tex](x^2-10x)+(y^2+8y) = 8[/tex]

Now lets complete the square of both equations

[tex](x^2-10x+25)+(y^2+8y +16) = 8 + 25 + 16\\(x-5)^2+(y+4)^2 = 49\\(x-5)^2+(y+4)^2 = 7^2[/tex]

Now we know the circle's general equation format is:

⇒[tex](x-h)^2+(y-k)^2 = r^2[/tex]

(h, k) ⇒ coordinate of the center of the circler ⇒ length of radius of circle

Thus the radius of the circle is 7

Hope that helps!

In an RPG game, each player can choose among 5 basic classes: Mage, Warrior, Archers, Priests, Monks. Each basic class can advance to 4 sub-classes. If each character can have two sub-classes at the same time, how many different combinations are there?

Answers

Answer:

In RPGs a Character Class is a designation that determines a player's abilities and fighting style (and depending on the game possibly even their origin, education, and home area) often in the form of a job or archetype. A character class is defined by the abilities that it lends to a character — as such, two different characters with the same class are theoretically interchangeable, in that they have the same "power set" and can play the same role in gameplay because of their similar abilities. However, character class systems can come with varying levels of customization — ranging from characters of a given class being literally identical to having so much variety that character class is no longer even a good indicator of that character's abilities. While most common in fantasy Role-Playing Games, they have recently began to appear in other genres, such as trading card games and MOBAs.

Determine whether [3x + 12 + x] is equivalent to [4(3 + x)]. Use properties of operations to justify your answer.

Answers

Answer:

3x + 12 + x = 4x + 12 becuase 3x and x are like terms so you can add them

4(3 + x) = 12 + 4x because 4 times 3 is 12 and 4 times x is 4x so you add them to get 12 + 4x which can be rearranged to equal 4x + 12

So in short: 3x + 12 +x is equivalent to 4(3+x)
