Solving the equation​ √(x - 3)³ - 64 = 0 for the variable x gives x = 19

From the question, we have the following parameters that can be used in our computation:

√(x - 3)³ - 64

Express as an equation

So, we have

√(x - 3)³ - 64 = 0

Add 64 to both sides of the equation

√(x - 3)³ = 64

Take the cube roots of both sides

So, we have

√(x - 3) = 4

Square both sides of the equation

This gives

x - 3 = 16

Add 3 to the equation

x = 19

Hence, the solution is x = 19

The probability that more than 8 and less than 12 customers pay in cash is 0.376 or 37.6%.

The probability that more than 8 and less than 12 customers pay in cash is calculated using the binomial probability formula:

where:

n is the number of trials = 15

x = customers who pay in cash

p = paying in cash, which is 0.4 according to the problem

The probability that more than 8 and less than 12 customers pay in cash. is the sum of the probabilities of 9, 10, and 11 customers paying in cash.

Using the binomial probability formula:

P(9) = 15C₉ * 0.4⁹ * 0.6⁶

P(9) = 0.212

P(10) = 15C₁₀ * 0.4¹⁰ * 0.6⁵

P(10) = 0.121

P(11) = 15C₁₁* 0.4¹¹ * 0.6⁴

P(11)= 0.043

Hence;

P(9 or 10 or 11) = 0.212 + 0.121 + 0.043

The value of the variable x for the triangle base length is derived as 5.

Using the proportionality theorem for evaluating x as follows:

JD/DK = PJ/PK

3x/(4x + 1) = 20/28

3x × 28 = 20(4x + 1) {cross multiplication}

84x = 80x + 20

84x - 80x = 20 {collect like terms}

4x = 20

x = 20/4 {divide through by 4}

x = 5

Therefore, the value of the variable x for the triangle base length is derived as 5.

The value of x and y are 32.02 and 13.3 respectively.

Pythagoras theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

If a and b are the legs of the triangle and c is the hypotenuse, then,

c² = a²+b²

Triangle EFG is a right angled triangle so also triangle DEG

Therefore,

x² = 25²+20²

x² = 625 + 400

x² = 1025

x = √1025

x = 32.02

Also,

y² = 24² - 20²

y² = 576 - 400

y² = 176

y = √176

y = 13.3

The probability that a randomly

red-shaded square is 63.7%.

A figure is shown, in which a square is inscribed in a circle. To find the probability that a randomly selected point within the circle falls in the red shaded area (Square).

radius  = 7cm

side of square = 7√2 cm

Area of the circle = πr²

                             = 3.14 * 7²

                             = 153.86 cm²

Area of the square = side * side

                               =  7√2 * 7√2

To reflect a point over the y-axis, we negate the x-coordinate of the point. To reflect the resulting point over the x-axis, we negate the y-coordinate of the point. So, to find the new point A'', we can perform these operations on the original point A:

1. Reflect A over the y-axis to get A': (-2, 2)

2. Reflect A' over the x-axis to get A'': (-2, -2)

Therefore, the new point A'' is (-2, -2).

The elimination method is a technique used to solve linear equations that comprise a system. The fundamental principle behind this methodology involves nullifying one of the variables.

It should be noted that to implement the elimination approach successfully, we must exclude either x or y, which can be accomplished by multiplying the second equation by an amount necessary to make the coefficient of y consistent in both the equations:

With x's value now discerned, we can insert it into any of the original equations to calculate y. This explains the method.

Answer:

1/20

Step-by-step explanation:

To multiply two fractions, you simply multiply their numerators (top numbers) together and multiply their denominators (bottom numbers) together.

So, for 2/5 x 1/8, we have:

(2/5) x (1/8) = (2 x 1) / (5 x 8) = 2/40 = 1/20

Therefore, 2/5 x 1/8 is equal to 1/20.

Multiplying the numerators and denominators directly is the most straightforward method to solve the multiplication of fractions. However, there is another method called cross-multiplication, which you can use to solve this problem as well.

To use cross-multiplication, you multiply the numerator of the first fraction by the denominator of the second fraction, and then multiply the denominator of the first fraction by the numerator of the second fraction.
Then, you simplify the resulting fraction.

So, for 2/5 x 1/8, we have:

(2/5) x (1/8) = (2 x 1) / (5 x 8)

Cross-multiplying, we get:

(2/5) x (1/8) = (2 x 1) / (5 x 8) = (2 x 1) / (5 x 8) = 2/40

Simplifying the fraction 2/40, we can divide both the numerator and denominator by 2, to get:

2/40 = 1/20

Therefore, using cross-multiplication, we get the same answer as before:

2/5 x 1/8 is equal to 1/20.

Answer:

Length = 120 yards, width = 30 yards.

Step-by-step explanation:

Lets use [tex]l[/tex] for length and [tex]w[/tex] for width.

The perimeter of a rectangular field is [tex]2l + 2w[/tex]. We can construct the following equations:

[tex]4w = l[/tex].

[tex]2l + 2w = 300.[/tex]

If we plug [tex]4w[/tex] in for [tex]l[/tex] into the second equation, we get:

[tex]2w + 2(4w) = 300.[/tex]

[tex]2w+8w = 300.[/tex]

[tex]10w = 300.[/tex]

[tex]w= 30.[/tex]

Plug 30 in for [tex]w[/tex] into the first equation.

[tex]l = 4*30 = 120.[/tex]

Length = 120 yards, width = 30 yards.

The data can be stored on the entire reel is 66,355,200 bits.

Now, length of of reel = 1200 feet

= 1200 x 12

By calculating the volume of both figures, we will see that 11,160 cubes can be fit in the prism.

Now, So we start with a rectangular prism that measures (7 + 1/2)cm by 12cm by (15 + 1/2) cm.

Hence, The volume is just the product of these 3 values,

so we get:

V = (7 + 1/2)cm × 12cm × (15 + 1/2)cm

V = 1,395 cm³

Now, a cube with an edge length of 1/2 cm has a volume of:

V' = (1/2cm)³

V' = 0.125 cm³

To see how many of the small cubes enter in the prism, we just need to take the quotient between these two volumes, this is:

V/V' = ( 1,395 cm³)/(0.125 cm³) = 11,160

It should be noted that to obtain the number of integers found in the multples of 8 that aren’t multiples either of 4 or 2, the intersection needs to be excluded from set A.
