Find the value of x. Round to the nearest tenth

Answer:

1. 672 inches

Step-by-step explanation:

Question #1

The formula for the volume of a triangular prism is:

V = [tex]\frac{bh}{2}[/tex]

Where V is the volume, b is the area of the base, and h is the height. You are given the volume and the height. Plug those numbers into your equation.

[tex]4704 = \frac{b(14)}{2}[/tex]

Now, solve for b. To do this, you must isolate the variable b.

The first step to do this is to multiply both sides by 2. This will get you:

4704(2) = 14b

9408 = 14b

Now, divide both sides by 14 to get:

672 = b.

Therefore, the area of the base is 672 inches.

Question #2

To solve this problem, separate the figure into 2 shapes. You have a triangle with a base of 6 cm and a height of 6 cm, as well as a semicircle with a radius of 3 cm.

After you do this, find the area of each shape separately.

The formula for the area of a triangle is:

[tex]A = \frac{bh}{2}[/tex],

where A is the area, b is the length of the base, and h is the height. You know the base and the height, so plug those into your equation. You will get:

[tex]A = \frac{6*6}{2}\\\\A = \frac{36}{2}\\\\A = 18[/tex]

Now you know that the area of the triangle is 18 cm^2.

Let's find the area of the semicircle.

The formula for the area of a semicircle is:

A = [tex]\frac{1}{2}[/tex]π[tex]r^2[/tex]

You know the radius, so plug that in to get:

A = [tex]\frac{1}{2}[/tex]π([tex]3^2[/tex])

A = [tex]\frac{1}{2}[/tex]π(9)

Simplify this to get:

A = 4.5π.

Now, either multiply 4.5 by π to get:

14.1371669412 cm^2

or, multiply 4.5 by 3.14 to get:

14.13 cm^2.

Then, add the area of the triangle, 18 cm^2, by the area of the triangle, 14.13, to get:

32.13 cm^2.

Hope this helps!

Step-by-step explanation: ....

The image of the point (2, -7) after reflection across the x-axis is (2, 7).

In mathematics, reflection is a transformation that flips a figure over a line or plane. The line or plane is called the axis of reflection, and each point of the figure and its image are equidistant from the axis of reflection.

We have the coordinates as (2, -7).

Now, the rule for reflection across x- axis is

(x, y) -> (x, -y)

When a point is reflected across the x-axis, its y-coordinate is negated.

Therefore, the image of the point (2, -7) after reflection across the x-axis is (2, 7).

Question 9 options:

Answer:

eight twelfths?

Step-by-step explanation: two twelfths is one sixths, four twelfths is one third, and three sixths is one half.

Answer:

1) 9/20

2) 5/11

Step-by-step explanation:

For the first question: We read the number "0.45" as "45 hundredths," and we write it as the fraction 45/100. Of course, since 45 and 100 share the common factor 5, we can reduce this fraction by dividing the numerator and denominator by 5 to get the reduced form 9/20.

For our second problem, we need to perform a bit of "mathematical surgery" to find the appropriate fraction for x = 0.454545... First, the dots tell us that this fraction is repeating - those 45s will keep going on and on forever. When we multiply x by 100, then, we move the decimal two places to the right, but the repeating part still remains, giving us

[tex]100x=45.454545\dots[/tex]

From here, we can "surgically remove" the repeating bit using our original value of x:

[tex]100x-x=45.454545\dots-0.454545\dots\\99x=45[/tex]

And from here, we just have to divide both sides of the equation by 99 to solve for x:

[tex]99x=45\\x=45/99\\x=5/11[/tex]

Answer:

22.22%

Step-by-step explanation:

Well first let's find the difference between 22 and 18. 22 - 18 = 4. There's a 4 point difference, so now we need to find out how much 4 is of 18. 4 is 22.22% of 18.

Answer:

x = 22

Step by step solution:

5x+(3x-18)+x=180

Simplifying

5x + (3x + -18) + x = 180

Reorder the terms:

5x + (-18 + 3x) + x = 180

Remove parenthesis around (-18 + 3x)

5x + -18 + 3x + x = 180

Reorder the terms:

-18 + 5x + 3x + x = 180

Combine like terms: 5x + 3x = 8x

-18 + 8x + x = 180

Combine like terms: 8x + x = 9x

-18 + 9x = 180

Solving

-18 + 9x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + 9x = 180 + 18

Combine like terms: -18 + 18 = 0

0 + 9x = 180 + 18

9x = 180 + 18

Combine like terms: 180 + 18 = 198

9x = 198

Divide each side by '9'.

x = 22

Simplifying

Answer:

7x

Step-by-step explanation:

First, let's factor the expression 7x² + 14x. The greatest common factor of 7x² and 14x is 7x. 7x² / 7x = x, and 14x / 7x = 2, so our factored expression becomes 7x(x + 2).

If we write our expression as a fraction now, we have

[tex]\dfrac{7x(x+2)}{x+2}[/tex]

And cancelling the x + 2 in the numerator and denominator gives us the value 7x.

Step-by-step explanation:

you move the 4p to the other side, making it negative,

- 4p + 19 = -5

then, you move the 19 to the other side, making it negative,

- 4p = -5 - 19

then you subtract,

- 4p = -24

divide by -4,

p = 6
