Answer:

x = 2

Step-by-step explanation:

To find the value of x, we simply need to use the know values for the lengths, widths, and perimeter of the rectangle.

The formula for the perimeter of a rectangle is as follows:

P = 2L + 2W

Where P is the perimeter, L is the length, and W is the width.

Let L = 7x + 5 and W = x - 3

Now, we will simply plug our values into the formula and solve for x.

P = 2L + 2W

36 = 2 ( 7x + 5 ) + 2 ( x - 3 )

36 = 14x + 10 + 2x + -6

36 = 16x + 4

32 = 16x

2 = x

Thus, we have found the value of x to be 2.

Answer:

For the code we have 3 selections.

The first selection is a digit that must be odd, so the options are {1, 3, 5, 7 ,9}

So we have 5 options.

The second selection is a letter from the set of all the letters (27) minus the set of the vowels (5)

So here we have 27 - 5 = 22 options

The third selection is also a letter from the previous set, but because each letter can be used only one time, and in the previous selection we already selected one of the letters, in this selection we have a letter less than in the previous selection.

Here we have 22 - 1 = 21 options.

The total number of combinations (of possible codes) is equal to the product of the number of options for each selection:

C = 5*22*21 = 2310.

There are 2310 different possible codes

Answer: [tex]h=\frac{2A}{(a+b)}[/tex]

Step-by-step explanation:

To solve for h, we want to get h alone. We need to use our algebraic properties.

[tex]A=\frac{1}{2} h(a+b)[/tex]                             [multiply both sides by 2]

[tex]2A=h(a+b)[/tex]                              [divide both sides by (a+b)]

[tex]h=\frac{2A}{(a+b)}[/tex]

Now that we have h alone, we know that [tex]h=\frac{2A}{(a+b)}[/tex].

Answer:

Answer:

Ms. Rangtonsmith will get $30 after raise

Step-by-step explanation:

Current salary = $25

raise = 1/5 of current salary

substituting current salary with $25

raise in dollar value = 1/5 of $25 = 1/5 *$25 = $5

Thus, raise is $5

total salary after raise will be sum of current salary and raise

total salary after raise = $25 + $5 = $30

Thus, Ms. Rangtonsmith will get $30 after raise

Step-by-step explanation:

A. What details can you determine about the dive from the coordinates of the point (5, -8)?

First component corresponds to time and second component to depth with respect to sea level. The diver is 8 feet below sea level at 5 seconds.

B. What is the average speed of the diver in the water? How can you tell from the graph?

The average speed of the diver ([tex]\bar v[/tex]), measured in feet per second, can be calculated by the following expression:

[tex]\bar v = \frac{x_{f}-x_{o}}{t_{f}-t_{o}}[/tex]

Where:

[tex]x_{o}[/tex], [tex]x_{f}[/tex] - Initial and final depth of diver, measured in feet.

[tex]t_{o}[/tex], [tex]t_{f}[/tex] - Initial and final instant, measured in seconds.

There are three different average speeds: (i) Descent ([tex]t = 1\,s[/tex] to [tex]t = 5\,s[/tex]), (ii) Ascent ([tex]t = 5\,s[/tex] to [tex]t = 9\,s[/tex]), (iii) Descent + Ascent ([tex]t = 1\,s[/tex] to [tex]t = 9\,s[/tex])

(i) Descent ([tex]t = 1\,s[/tex] to [tex]t = 5\,s[/tex])

[tex]x_{o} = 0\,ft[/tex] and [tex]x_{f} = -8\,ft[/tex]

[tex]\bar v_{i} = \frac{-8\,ft-0\,ft}{5\,s-1\,s}[/tex]

[tex]\bar v_{i} = -2\,\frac{ft}{s}[/tex]

(ii) Ascent ([tex]t = 5\,s[/tex] to [tex]t = 9\,s[/tex])

[tex]x_{o} = -8\,ft[/tex] and [tex]x_{f} = 0\,ft[/tex]

[tex]\bar v_{ii} = \frac{0\,ft-(-8\,ft)}{9\,s-5\,s}[/tex]

[tex]\bar v_{ii} = 2\,\frac{ft}{s}[/tex]

(iii) Descent + Ascent ([tex]t = 1\,s[/tex] to [tex]t = 9\,s[/tex])

[tex]x_{o} = 0\,ft[/tex] and [tex]x_{f} = 0\,ft[/tex]

[tex]\bar v_{iii} = \frac{0\,ft-0\,ft}{9\,s-1\,s}[/tex]

[tex]\bar v_{iii} = 0\,\frac{ft}{s}[/tex]

C. Which point on the graph shows the starting location of the diver?

The initial location is when [tex]t = 0\,s[/tex], which corresponds to the intercept of the line on y-axis.

Step-by-step explanation:

DALLAS = 6!

6x 5 x 4 x 3 x 2 x 1

720 ways

The letters of the word DALLAS can be arranged in 720 distinct ways.

Multiplication is the mathematical operation that is used to determine the product of two or more numbdistinctn event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

A word has n letters. then there are m repeating letters, each of them repeating r0, r1, r2.. times

So the number of distincts ways the letters DALLAS can be arranged are:

DALLAS = 6!

= 6x 5 x 4 x 3 x 2 x 1

= 720 ways

The letters of the word DALLAS can be arranged in 720 distinct ways.

Answer:

The scale factor is 1/48

Step-by-step explanation:

First, we need to convert 60 feet to inches.

60 feet = 720 inches

Then, we divide 720 by 15

720/15= 48.

The scale factor is 1/48.

The scale factor of dilation is given by the proportion and A = 48

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

We can use the ratio of the lengths of the corresponding sides to find the scale factor or dilation factor used by the architect.

Let A be the factor of dilation used by the architect. Then we can set up the following proportion:

60 feet / A = 15 inches / 1

We can solve for x by cross-multiplying:

60 feet x 1 = A x 15 inches

A = (60 feet) / (15 inches)

We need to convert feet to inches to get the units to match:

A = (60 feet) / (15 inches) x (12 inches / 1 foot)

Simplifying, we get:

A = 720 / 15

A = 48

Hence , the architect used a scale factor of 48 when creating the scale drawing of the house

Answer:

(0, -5) and (4, 3)

Step-by-step explanation:

I assume you're looking for the coordinates of the intersections, if any.

Solve by substitution:

x² + (2x − 5)² = 25

x² + 4x² − 20x + 25 = 25

5x² − 20x = 0

5x (x − 4) = 0

x = 0 or 4

So the coordinates are (0, -5) and (4, 3).

Answer:

Step-by-step explanation:

Let us denote probability of   spoilage as follows

Transformer spoilage = P( T ) ; line spoilage P ( L )

Both P ( T ∩ L ) .

Given

P( T )  = .05

P ( L ) = .08

P ( T ∩ L ) = .03

a )

For independent events

P ( T ∩ L ) =  P( T ) x  P ( L )

But  .03  ≠  .05 x .08

So they are not independent of each other .

b )

i )

Probability of line spoilage given that there is transformer spoilage

P L/ T ) = P ( T ∩ L ) / P( T )

= .03 / .05

= 3 / 5 .

ii )

Probability of transformer spoilage but not line spoilage.

P( T ) - P ( T ∩ L )

.05 - .03

= .02

iii )Probability of transformer spoilage given that there is no line spoilage

[ P( T ) - P ( T ∩ L ) ] / 1 - P ( L )

=  .02 / 1 - .08

= .02  / .92

= 1 / 49.

i v )

Neither transformer spoilage nor there is no line spoilage

= 1 - P ( T ∪ L )

1 - [  P( T ) +  P ( L ) - P ( T ∩ L ]

= 1 - ( .05 + .08 - .03 )

=  0 .9

Answer:

(x-1)²/64 + (y-2)²/144 = 1

Step-by-step explanation:

The standard equation of an ellipse is expressed as (x-h)²/a² + (y-k)²/b² = 1

Where the coordinate (h,k) is the centre of the ellipse.

a is the the difference of the x coordinates of the centre and the vertex.

b is the minor axis.

Given the centre to be (1,2), on comparing with the coordinate (h,k),

h = 1 and k = 2

The difference of the x coordinates of the centre and the vertex = -7-1 = -8

The minor axis as given in the equation is b = 12

Substituting the given parameters into the equation of an ellipse above we will have;

(x-1)²/(-8)² + (y-2)²/12² = 1

(x-1)²/64 + (y-2)²/144 = 1

The final equation gives the required standard form of the equation of the ellipse.
