If x represents the length of the first piece, find the lengths of all three pieces
What is the length of the first piece?

Answers

Answer 1
Im pretty sure the first piece is 9 and then 9 x 3 = 27 and then 9 x 5 is 45 so piece on is 9 piece 2 is 27 and piece 3 is 45 :)

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)

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

What is an easy method to solve for x in a basic algebra problem? Example: 3x + 5x + 8x = 32

Answers

Answer:

2

Step-by-step explanation:

3x + 5x  + 8x = 32

taking x common,

(3 + 5 + 8)x = 32

16x = 32

x = 32 / 16

x = 2

Answer: See below

Explanation:

The ultimate method of solving algebra problems will be trying any operations to isolate x, which then gives the value of x.

Operations include combining like terms, dividing and multiplying terms, and etc.

I would be solving [3x + 5x + 8x = 32] as an example.

Solve:

Given

3x + 5x + 8x = 32

Combine like terms through addition

8x + 8x = 32

16x = 32

Divide 16 on both sides to isolate x

16x / 16 = 32 / 16

[tex]\boxed {x=2}[/tex]

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

A base angle of an isosceles triangle contains 75º. How large is the vertex angle?

(B) 30°
(C) 1050

Answers

Answer is B, there are two equal base angles in an isosceles triangle, so given that ( 75+75 =150), the total of the interior angles in any triangle is 180, so 180-150 =30 ( which is the vertex angle) , the upper angle of the triangle.
It’s B because it has to have a lower side plus it can’t be greater tag. 75 the. It will be inaccurate

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
