Which expression is equivalent to 3/4 divided by 5/7

The equation of a line that is perpendicular to 2y 3x 10 and passes through (- 6 1) is -3y + 2x -1 with slope.

1. Start by finding the slope of the given line by taking the coefficient of x and dividing it by the coefficient of y.

2. To find the slope of the line perpendicular to the given line, we need to find the negative reciprocal of the slope of the given line.

Slope of the perpendicular line: m = -2/3

3. We know that the equation of a line in slope intercept form is: y = mx + b, where m is the slope and b is the y-intercept.

4. So, the equation of the line perpendicular to 2y 3x 10 and passes through (-6 1) is:

y = -2/3x + b

5. To find the y-intercept, substitute the given point (-6 1) in the equation and solve for b.

-1 = -2/3(-6) + b

b = 1

6. Therefore, the equation of a line that is perpendicular to 2y 3x 10 and passes through (- 6 1) is -3y + 2x -1

Parallel lines are coplanar lines that have a fixed distance between them and do not meet.

The specified information are;

the lines that are on the same plane = a, b, and c

The relationship between line a and b = a is perpendicular to b (a ⊥ b)

The relationship between line b and c = b is perpendicular to c (b ⊥ c)

The slope of a line perpendicular to another line with slope, m, is the negative inverse of m or -1/m

(The slope of parallel lines are the same)

Let the slope of line a = m, therefore;

The slope of the line b  which is perpendicular to a is -1/m

Therefore, the relationship between the lines b and c which are perpendicular (b ⊥ c) is as follows;

The slope of the line b = -1/m, therefore;

The slope of the line c, perpendicular to b is the negative inverse of the slope  of b

The slope of the line c = -1/(-1/m)) = 1/(1/m) = m

Answer: 7/8?

Step-by-step explanation:

A. The equations for the amounts of money Lyle and Shaun have in their accounts are represented as:

f(x) = 20x + 100

g(x) = 10x + 500

B. When f(x) = g(x), x = 40.

A linear equation can be written in slope-intercept form y = mx + b. Here, the value of m is the unit rate or slope, while the value of b is its y-intercept or initial value.

Part A:

Equation for Lyle:

y-intercept / initial value (b) = $100

Slope / unit rate (m) = $20

To write the equation, substitute m = 20 and b = 100 into f(x) = mx + b:

f(x) = 20x + 100.

Equation for Lyle:

y-intercept / initial value (b) = $500

Slope / unit rate (m) = $10

To write the equation, substitute m = 10 and b = 500 into g(x) = mx + b:

g(x) = 10x + 500.

Part B: To solve the system, we would do the following:

20x + 100 = 10x + 500

20x - 10x = -100 + 500

10x = 400

x = 400/10

The function in variable w giving the cost C (in dollars) of constructing the box is C(w) = 30w² + 270/w. The result is obtained by using the formula of volume and area of the box.

We have a rectangular storage container without a lid.

The formula of volume of the box is

V = l × w × h

Where

So, the height is

10 = 2w × w × h

10 = 2w² × h

h = 10/2w²

h = 5/w²

To find the total cost, calculate the area of base and sides of the box!

See the picture in the attachment!

The base area is

A₁ = 2w × w = 2w² m²

The sides area is

A₂ = 2(2wh + wh)

A₂ = 2(3wh)

A₂ = 6wh

A₂ = 6w(5/w²)

A₂ = 30/w m²

The total cost is

C = $15(2w²) + $9(30/w)

C = $30w² + $270/w

The function of the total cost is

C(w) = 30w² + 270/w

Hence, the function of constructing the box is C(w) = 30w² + 270/w.

Using the properties of a 45-45-90 triangle, [tex]x=\sqrt{2}(6\sqrt{2})=12[/tex].

The expected area of a random square which has a side length that is uniform random variable is 1/3.

A family of symmetric probability distributions includes the continuous uniform distribution and rectangular distribution. The distribution describes an experiment with a random result that falls within predetermined bounds.

 The parameters, a and b, which represent the minimum and maximum values, define the bounds. The interval may be closed (for example, [a, b]) or open (for example, (a, b)). common abbreviation for the distribution is U (a, b), where U stands for uniform distribution. 

The length of the interval is defined by the difference between the bounds; intervals with the same length on the distribution's support are equally likely.

Let, side of the square = X

we know that the area of a square = side × side

                                                          =  X  ×  X

                                                          =  X^{2}

now, by using Continuous uniform distribution,

E[ X^{2} ] =  [tex]\int\limits^1_0 X^{2} \, dx[/tex]    

                =  [tex][\frac{1^{3} }{3} - \frac{0^{3} }{3} ][/tex]
