Answer:

6m * 4m * 2m

Step-by-step explanation:

Given that :

Cubic volume = 48 m³

Possible dimension if none of the dimensions is 1 m

Volumetric Dimension = (length * width * height)

The product of the three dimensions must give 48m³

Constraint : none of the dimensions has a volume of 1 m.

Hence, possible dimension :

6m * 4m * 2m = 48m²

Hence, one possible dimension is :

6m * 4m * 2m

Answer:

x = - 4

Step-by-step explanation:

y = -x - 6

2x - 3y = -2

Insert the first equation y = -x-6 into the second 2x - 3y = -2 .

2x - 3 (-x-6) = -2

2x +3x + 18 = -2

5x = -2 - 18

5x = - 20

x = - 20/5

x = - 4

Answer:  A. The mean absolute deviation is 4

Step-by-step explanation:

Mean absolute deviation (MAD) is found by finding the absolute value of difference between each number in set and mean, adding them together, then dividing by total numbers in set.

Differences

72-62= 10

72-73= 1

72-74= 2

72-75= -3

72-76= -4

add the absolute values...

Answer:

A. 60°

Step-by-step explanation:

∠BEC = 1/2 arc BC = 32°

∠CED = ∠BED - ∠BEC = 62° - 32° = 30°

arc CD = 2 x ∠CED = 2 x 30° = 60°

The measure of the arc CD of the circle is 60°

Given data:

The central angle is an angle with two arms and a vertex in the middle of a circle.

The central angle of a circle formula is as follows.

Central Angle = ( s x 360° ) / 2πr

And, Central Angle = 2 x Angle in other segment

So,

∠BEC = 1/2 arc BC = 32°

The measure of the angle ∠CED  is determined as:

∠CED = ∠BED - ∠BEC = 62° - 32° = 30°

So, the measure of the arc from the central angle is:

arc CD = 2 x ∠CED = 2 x 30° = 60°

Hence , the measure of arc CD = 60°

Answer:

16(x + 3)

4(7x + 8y)

w(11 + h)

Step-by-step explanation:

16x + 48

The greatest common factor of 16 and 48 = 16

Hence, expressing 16x + 48 in factored form:

16x + 48 = 16(x + 3)

28x + 32y

Greatest common factor of 28 and 32 = 4

Hence,

28x + 32y = 4(7x + 8y)

11w + hw

11w + hw = w(11 + h)

Answer:

B and D are correct.

Step-by-step explanation:

First, we find the length of ALL the sides using the Pythagorean Theorem.

16² + b² = 20²

256 + b² = 400

b² = 144

[tex]\sqrt{144}[/tex] = 12

Now, we know that sine is opp/hyp, cosine is adj/hyp, and tangent is opp/adj.

A is incorrect because that's supposed to be cos. B is correct because that is indeed cos. C is incorrect. D is correct. E and F are incorrect because it's supposed to be sin.

Don't know if any of that made sense. All you need to do is remember the difference between sine, cosine, and tangent.

Answer:

The answer is B and D.

Step-by-step explanation:

Length of ladder AC = 20 feet

Height of the highest point of the ladder from ground AB = 16 ft

By Pythagoras theorem,

AC² = BC² + AB²

BC² = AC² - AB²

BC = √(20)^2-(16)^2

     = √400-256

     = √144

     = 12

Now, Sinθ = opposite side/hypotenuse = AB/AC

                 = 16/20

Cosθ = adjacent side/hypotenuse = BC/AC

         = 12/20

Therefore, A and D are the correct options.

The area of the circle is equal to 144π square inches.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.

Given that the circumference of a circle is 24π in. The area of the circle is calculated by the formula given below,

Area of circle = πr²

Circumference of the circle = 24π

2πr = 24π

r = 12

The area of the circle will be calculated as:-

Area = πr²

Area = π x ( 12 )²

Area = 144π square inches.

Hence, the area is 144π square inches.

Answer: A. 5x+x+18 = 180

Step-by-step explanation:

For B you need to find the value of x first.

5x + x + 18 = 180 is your equation.

Combine like terms: 5x+x = 6x

Equation should now look like this

6x + 18 = 180

Subtract 18 to both sides 180-18 = 162

Do 162/6 = 27

X = 27

13. [tex]C=6\pi[/tex]

14. [tex]C=9\pi[/tex]

15. [tex]C=7\pi[/tex]

Step-by-step explanation:

To find the circumference of a circle, the formula is [tex]C=2\pi r[/tex], with "C" being the circumference and "r" being the radius.

In question 13, the radius (r) is shown as 3ft. When you put this into the equation, it should look like this:

[tex]C=2\pi (3)[/tex]

Simplify.

[tex]C=6\pi[/tex]

Follow the same steps in questions 14 and 15. In 14, 9 is the diameter, which makes the radius 4.5.

The final answers are shown above.

The value of the angles should be. (x-40°). , (x-20°), (½x-10°) , not (x-40°) + (x-20°)+(½x-10°)

Sum of all the interior angles of a triangle is 180°.

So a equation can be made by the given data,

(x-40°) + (x-20°) + (½ x-10°) = 180°

x-40°+x-20°+½x-10° = 180°

2x+½x -60°-10° = 180°

5/2 x - 70° = 180°

5/2 x = 180° + 70°

5/2 x = 250°

x = 250° × 2/5

x = 50° × 2

x = 100°

So the angles are

x-40° = 100°-40° = 60°

x-20° = 100°–20° = 80°

½x-10° = ½(100)° - 10° = 50° -10° = 40°

The answer can be checked by putting the values of the angle we got in the second statement i.e. Sum of all the interior angles of a triangle is 180°.

60° + 80° + 40° = 100° + 80° = 180°
