How many centimeters of cubic amounts to the volume of the cube with a edge of 0.1 m​

Answers

Answer:

[tex]V=1000\ cm^3[/tex]

Step-by-step explanation:

The edge of the cube, a = 0.1 m

We need to find the volume of the cube. The formula for the volume of the cube is given by :

[tex]V=a^3[/tex]

Put the respected values,

[tex]V=(0.1)^3\\\\V=0.001\ m^3\\\\or\\\\V=1000\ cm^3[/tex]

So, the volume of the cube is equal to [tex]1000\ cm^3[/tex].

Using it's formula, it is found that the Mean Absolute Deviation is given by:

D.4.24

What is the mean absolute deviation of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.

In this problem, the mean is given by:

[tex]M = \frac{5 + 11 + 2 + 7 + 16}{5} = 8.2[/tex]

Hence, the mean absolute deviation is given by:

[tex]M_d = \frac{|5-8.2| + |11-8.2| + |2-8.2| + |7-8.2| + |16-8.2|}{5} = 4.24[/tex]

Hence option D is correct.

Step-by-step explanation:

What you are dealing with is what we call special right triangles. There are two types of right triangles.

30-60-90 triangle- A special

right triangle with side length ratio as

[tex](a)(a \sqrt{3} )(2a)[/tex]

, where a is any positve number

45-45-90- a special right triangle which side length ratios are

[tex](a)(a)(a \sqrt{2)} [/tex]

where a is any positve number.

45 45 90 triangles is indicated by two congruent side measures( if the legs are congruent and it has a right angle, it is a 45-45-90.

30-60-90 triangles is indicated by a having at least two of the following angles given (30,60, and 90).

Shortcuts:

For a 45 45 triangle,

the legs are equal while the hypotenuse is the sqr root of 2 times than the legs.

Example, look at 1. The legs side length is 12 so our hypotenuse side length will be

[tex]12 \sqrt{2} [/tex]

For a 30-60-90 triangle, the side that is adjacent to the 30 and 90 degree measure sqr root of 3 times more than the horizontal leg.

the slanted side or the side which is adjacent to the 30 and 60 degree angle is twice the length of the horizontal leg or the side that is adjacent to the 60 and 90 degree.

Example, look at 3. We need to find x but we are given the horizontal side so just multiply sqr root of 3 to 12.

[tex]x = 12 \sqrt{3} [/tex]

[tex]1.12 \sqrt{2} [/tex]

2.Both equal

[tex]2.8 \sqrt{2} [/tex]

[tex]3.12 \sqrt{3} [/tex]

A group of friends wants to go to the amusement park. They have no more than $245 to spend on parking and admission. Parking is $9.25, and tickets cost $25.75 per person, including tax. Which inequality can be used to determine pp, the maximum number of people who can go to the amusement park?

Answers

Answer:

25.75x+9.25

Step-by-step explanation:

9.25 is the constant. You multiply the ticket by the amount of people to get ticket cost. Then you add ticket cost 9.25 to get final answer.

Inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

We have been given that the group of friends has no more than $245  to spend on parking and admission.

And the parking is $9.25, and tickets cost $25.75 per person, including tax.

Let the number of people would be p who can go to the amusement park,

So the inequality that expresses the relationship is

⇒ 9.25 + 25.75 × p ≤ 245  

Therefore, inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.

Step-by-step explanation:

If AB=4 feet & AD=10 feet & m What is DC?
What is BD?
What is m What is m

Answers

Answer:

1. DC = AB = 4 ft

2. BD = 10.80 ft

3. m<CED = [tex]90^{0}[/tex]

4. m<EBC = [tex]65^{o}[/tex]

Step-by-step explanation:

From the given quadrilateral,

Given: AB = 4 ft, AD = 10 ft and m<BAE = 65.

1. DC = AB = 4 ft (opposite sides of a parallelogram are equal)

2. Applying the Pythagoras theorem to ΔABD, we have;

[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]

[tex]BD^{2}[/tex] = [tex]4^{2}[/tex] + [tex]10^{2}[/tex]

       = 16 + 100

       = 116

BD = [tex]\sqrt{116}[/tex]

     = 10.7703

BD = 10.80 ft

3. m<CED = [tex]90^{0}[/tex] (the diagonals bisects each other at right angle)

4. m<ABC + m<BAC + m<ACB = 180

90 + 65 + m<ACB = 180

m<ACB = 180 - 155

m<ACB = [tex]25^{0}[/tex]

So that,

m<BEC + m<EBC + m<ECB = 180

90 + m<EBC + 25 = 180

m<EBC = 180 - 115

m<EBC = [tex]65^{o}[/tex]

What is the median of a data-set?

The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.

The dot plot gives the number of times each measure appears, hence in this problem, the data-set is composed by:

{81, 82, 83, 83, 84, 84, 85, 85}

Even cardinality, hence the median is the mean of the two middle elements, 83 and 84, hence:

M = (83 + 84)/2 = 83.5.

The median of the data in the dot plot is 83.5.

In ΔHIJ, the measure of ∠J=90°, the measure of ∠I=72°, and JH = 1.2 feet. Find the length of HI to the nearest tenth of a foot.

Answers

Answer:

1.3

Step-by-step explanation:

Looking at the triangle, the first thing we can notice is that it is a right triangle, so we can use trigonometric ratios to solve for missing sides.

The side the problem is asking us to find is leg HI, which happens to be the hypotenuse of triangle HIJ.

We also know one side length: HJ= 1.2 ft, and one angle measure: ∠I=72°.

In these types of problems, there are two trigonometric ratios we can look to:

Sine or  sin(x)= opposite/hypotenuseCosecant or csc(x)= hypotenuse/opposite

You can actually use either of these to solve your problem, but for convenience let's use cosecant.

Cosecant of 72° will be equal to HI (the hypotenuse length) divided by HJ (the length of the opposite leg of angle I) Cosecant of 72° will be equal to HI divided by 1.2 (substitute the given length for HJ)1.05146222424 (plug csc(72°) into a calculator)=HI/1.2 1.05146222424*1.2=HI (multiply each side of the equation by 1.2) HI=1.26175466909 (simplify) HI≈1.3 (round the simplified number to the nearest tenth, as the problem requests)

[tex]\bold{a^2+b^2=c^2}[/tex] is indeed the Pythagorean theorem. It implies that adding the hypotenuse square as well as the two sides of a right triangle equals the hypotenuse square.

Calculating value by using the Pythagorean theorem:

The smallest side of the triangle in this instance contains 36 squares, which equals [tex]\bold{6^2}[/tex]. The triangle's bigger side has 64 (or [tex]\bold{8^2}[/tex]) squares.
