What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Given expression,
= √[75m⁹/196m⁴]
= √[25m⁴/196[3m]]
= 5m/14√3m    [since 25 = 5² and 196 = 14²]

If we inscribe a circle such that it is touching all six corners of a regular hexagon of side 10 inches, what is the area of the Circle that is not covered by the hexagon? ( with explanation )

Answers

Answer:

[tex]\left(100\pi - 150\sqrt{3}\right)[/tex] square inches.

Step-by-step explanation:

Area of the Inscribed Hexagon

Refer to the first diagram attached. This inscribed regular hexagon can be split into six equilateral triangles. The length of each side of these triangle will be [tex]10[/tex] inches (same as the length of each side of the regular hexagon.)

Refer to the second attachment for one of these equilateral triangles.

Let segment [tex]\sf CH[/tex] be a height on side [tex]\sf AB[/tex]. Since this triangle is equilateral, the size of each internal angle will be [tex]\sf 60^\circ[/tex]. The length of segment

[tex]\displaystyle 10\, \sin\left(60^\circ\right) = 10 \times \frac{\sqrt{3}}{2} = 5\sqrt{3}[/tex].

The area (in square inches) of this equilateral triangle will be:

[tex]\begin{aligned}&\frac{1}{2} \times \text{Base} \times\text{Height} \\ &= \frac{1}{2} \times 10 \times 5\sqrt{3}= 25\sqrt{3} \end{aligned}[/tex].

Note that the inscribed hexagon in this question is made up of six equilateral triangles like this one. Therefore, the area (in square inches) of this hexagon will be:

[tex]\displaystyle 6 \times 25\sqrt{3} = 150\sqrt{3}[/tex].

Area of of the circle that is not covered

Refer to the first diagram. The length of each side of these equilateral triangles is the same as the radius of the circle. Since the length of one such side is [tex]10[/tex] inches, the radius of this circle will also be [tex]10[/tex] inches.

The area (in square inches) of a circle of radius [tex]10[/tex] inches is:

[tex]\pi \times (\text{radius})^2 = \pi \times 10^2 = 100\pi[/tex].

The area (in square inches) of the circle that the hexagon did not cover would be:

[tex]\begin{aligned}&\text{Area of circle} - \text{Area of hexagon} \\ &= 100\pi - 150\sqrt{3}\end{aligned}[/tex].

The volume of a figure is 3250 cm^3. If the dimensions are multiplied by 1/5, what will be the volume of the new figure? Numerical answers only

Answers

Answer:Volume = length x width x height.

You only need to know one side to figure out the volume of a cube.

The units of measure for volume are cubic units.

Volume is in three-dimensions.

You can multiply the sides in any order.

Which side you call length, width, or height doesn't matter.

Step-by-step explanation:

The solution is: 216.6 cm^3 will be the volume of the new figure.

What is volume?

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

we know that,

Volume = length x width x height.

You only need to know one side to figure out the volume of a cube.

The units of measure for volume are cubic units.

Volume is in three-dimensions.

here, we have,

The volume of a figure is 3250 cm^3.

now, we have,

If the dimensions are multiplied by 1/5,

then, we have,

Volume = length/5 x width/5 x height/5.

or, Volume = length x width x height / 15

or, Volume = 3250/ 15 cm^3

or, V = 216.6 cm^3

Hence, 216.6 cm^3 will be the volume of the new figure.

Please help FAST

Answers

Answer:

$3.75/lb

Step-by-step explanation:

First, let's set up a proportion. The top number represents the cost, while the bottom number represents how many pounds. In order to get a unit rate, we need to figure out how much it costs for 1 pound.

[tex]\frac{13.5}{3.6} =\frac{x}{1}[/tex]

Now, cross multiply. To cross multiply, you would multiply 13.5 by 1 and 3.6 by x.

[tex]13.5 * 1 =13.5\\3.6*x=3.6x[/tex]

Set these two equal to each other.

[tex]13.5=3.6x[/tex]

Divide both sides by 3.6 to get x.

[tex]\frac{13.5}{3.6} =\frac{3.6x}{3.6}\\x=3.75[/tex]

For unit rates, you have to write your answer as per unit. To do that, put a slash next to your answer, and then your unit.

Complete the equation of the line whose slope is -2 and y-intercept is (0,-8)

y=

Answers

Answer:

y = -2x - 8

Step-by-step explanation:

We want to find the slope-intercept form of this equation. Slope-intercept form is denoted by: y = mx + b, where m is the slope and b is the y-intercept.

We already know that the slope is -2, so that means m = -2.

We also know the y-intercept (or the point where the line crosses the y-axis) is (0, -8), which means b = -8.

Thus, our equation is: y = -2x - 8.
