find the edge length of a cube whose volume is 1.728cubic cm is the edge length a rational number ​

Answers

Answer 1

The edge lengths of a cube that has a 1.728 cm³ volume is 1.2 cm

What is the volume of a cube?

The volume of a cube is the given by the length of one edge raised to the power of 3

The volume of a cube, V = Length, L × Width, W × Height, H

Given that the lengths of the edges of a cube are equal, we have!

Length, L = Width, W = Height, H

Which gives;

The volume of a cube, V = L × L × L = L³

Therefore, for the given cube, we have;

L³ = 1.728 cm³

1.728 = 1728/1000

(a + b)³ = a³ + 3•a²•b + 3•a•b² + b³

Taking a = 10, and b = 3, we have;

(10 + 2)³ = 10³ + 3×10²×2 + 3×10×2² + 2³ = 1728

Therefore;

1728/1000 = (10 + 2)³/10³ = 12³/10³

Which gives;

L³ = 12³/10³

[tex] \displaystyle {L = \sqrt[3]{ \frac{{12}^{3} }{ {10}^{3} } } = 1.2}[/tex]

The edge lengths of the cube, L = 1.2 cm

f(x)= 3x; translation up 5 units

Answers

After applying the given translation we get the function as 3x + 5

Graph translation is the process of converting an equation or existing graph into a new graph.

One common type of algebraic issue is changing algebraic equations.

A parent function's graph is altered by a translation. The three different types of translation are dilations, reflections, and translations.

A function can have its y-values modified vertically or its x-values changed horizontally (affects the x-values).

We are aware that the x- and y-coordinates must be modified to reflect the translation by the specified amount.

f( x ) = 3x is translated 5 units upwards.

Therefore the required graph is f ( x ) = 3x + 5 .

Calculate the product or quotient 8/7x4 + 7/4x7
Calculate the product or quotient 8/28 + 7/4x7
Calculate the product or quotient 8/28+7/28
Write the numerators over common denominator 8+7/28
Calculate the sum or difference 15/28
Convert to fraction 15/28
So the answer is 15/28

Darlene has 6 3/4 gallons of gasoline. Every time she mows her lawn, she uses 3/8 gallon. How many times can she mow her lawn before she needs more gas?w

Answers

The number of times Darlene mow her lawn before she needs more gasoline is equal to 18times.

As given in the question,

Total gasoline with Darlene is equal to 6 3/4 gallons

Convert mixed fraction into proper fraction:

6 3/4 = 27/4 gallons

Every time amount of gasoline used to mow her lawn = 3/ 8gallon

Number of times Darlene mow her lawn before she needs more gasoline

= (27 / 4) ÷ (3 /8)

= (27 /4) × (8/3)

= 18 times

Therefore, the number of times Darlene mow her lawn before she needs more gasoline is equal to 18times.

Graph the image of the figure using the transformation given.

Answers

A graph of the image of figure Q'R'S'T' after a dilation of 2 units about the origin is: graph C.

What is dilation?

Dilation simply refers to a type of transformation which changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

What is scale factor?

A scale factor can be defined as the ratio of two (2) corresponding length of sides or diameter in two similar geometric figures such as triangles.

Note: Each interval on this graph represents 1 unit.

For the given coordinates, the dilation with a scale factor of 2 about the origin or a center of dilation (0, 0) should be calculated as follows:

Point Q (-2, -1) → Point Q' (-2 × 2, -1 × 2) = Point Q' (-4, -2).

Point R (-1, 2) → Point R' (-1 × 2, 2 × 2) = Point R' (-2, 4).

Point S (1, 0) → Point S' (1 × 2, 0 × 2) = Point S' (2, 0).

Point T (2, -2) → Point T' (2 × 2, -2 × 2) = Point T' (4, -4).

A study on students drinking habits wants to determine the true average number of alcoholic drinks all uf greek students have in a one week period. We know from preliminary studies that the standard deviation is around 6. 3. How many students should be sampled to be within 0. 5 drink of population mean with 95% probability?.

Answers

Number of students need to be sampled = 610

A study to determine the true average number of alcoholic drinks consumed by Greek students is conducted.

Standard Deviation, σ = 6.3

Margin Error of population mean, E = 0.5

Probability = 95% = 0.95

The p-value corresponding to 0.95 probability = (1+0.95)/2 = 0.975

The z-score corresponding to this p-value = 1.96 [from the z-tables]

Now, The margin error, E = zσ/√n, where n is the sample size

⇒ n = (zσ/E)²

⇒ n = (1.96 x 6.3/0.5)²

⇒ n ≈ 610

Hence 610 students need to be sampled.

Answer:

No

Step-by-step explanation:

to determine if (2, 1 ) is a solution, substitute the x- coordinate into the equation and if the result is equal to the y- coordinate then it is a solution.

y = 9x ( substitute x = 2 )

y = 9 × 2 = 18 ≠ 1

then (2, 1 ) is not a solution to the equation.

what is the probability that maximum speed differs from the mean value by at most 2.5 standard deviations? (round your answer to four decimal places.)

Answers

The probability that maximum speed differs from the mean value by at most 2.5 standard deviations is 0.8473

Let the required probability that the maximum speed of mopeds differs from the mean speed by 2.5 standard deviations be given by P(U±2.5).

Mean speed U =46.7km/hr

P(46.7±2.5) = (44.2<= X <=49.2)

= P( 44.2<= Z <= 49.2)

= P(44.2 - 46.7/1.75 <= Z <= 49.2- 46.7/1.75)

= P( - 1.4286 <= Z <= 1.4285)

= P(1.4285) - P(-1.4285)

= P(1.43 ) - P(-1.43)

= 0.92364 - 0.07636

= 0.8473

Thus the probability that maximum speed differs from mean value by at most 2.5 standard deviations is 0.8473
