Mary's speed = 51 mph

Friend's speed = 66 mph

Mary will be on the road for t hours

Her Friend will be on the road t - 0.5. Why minus? Because she was on the road 1/2 hour less than Mary was. Any time you see More or Less in a question, pay attention. usually it is the key to the question.

Equation

d_Mary = d_friend

d = rate * time

Solution

51 * t = 66*(t - 0.5)                 Remove the brackets.

51*t = 66*t - 66*0.5

51*t = 66*t - 33                    Subtract 66t from both sides. Be careful

51t - 66t = - 33                     Combine

- 15t = - 33                            Divide by - 15

t = - 33/-15

t = 2.2 hours or 2 hours and 12 minutues

There are 2322432 coupons generated .

According to the question we have been given that the code contains one digit followed by four letters . That is it can be assumed as

                         code = D L L L L   where D and L represent the digits and letters.

Now total digits we have is  = 7

       total number of letters we have = 24

So we have to choose the first digit from these 7 digits. Thus there are 7 ways in which we can choose as they are repeated.

Also there are 24 ways to select the 4 letters after the digits as the letters are being repeated, that is ways =   24⁴

Therefore the number of coupons that can be generated from the combination are :

                                7*24⁴ = 7*331776

                                          = 2322432

Hence the number of coupons generated are 2322432.

The labeled graph showing ABCDE, A'B'C'D'E', and the line of reflection x = -2 is shown. Also, m∠ A = m∠ A'.

In the question, we are given that the polygon ABCDE is reflected across the line x = - 2.

We are asked to graph and label the image A'B'C'D'E'. Also, we are asked if m∠ A = m∠ A'.

When the polygon ABCDE is reflected across the line x = - 2, all the coordinates on it are reflected across the line x = -2.

The reflection of any point with coordinates (x, y) on reflection across the line x = a, results in a point with coordinates (-x + 2a, y).

The coordinates of the vertices of the given polygon are:

A (-4, 4), B (-3, 3), C (-3, 2), D (-5, 1), and E (-5, 3).

Reflecting these points across the line x = - 2, we get:

A (-4, 4) → A' ( -(-4) + 2(-2), 4) = A' (0, 4).

B (-3, 3) → B' ( -(-3) + 2(-2), 3) = B' (-1, 3).

C (-3, 2) → C' ( -(-3) + 2(-2), 2) = C' (-1, 2).

D ( -5, 1) → D' ( -(-5) + 2(-2), 1) = D' (1, 1).

E (-5, 3) → E' ( -(-5) + 2(-2), 3) = E' (1, 3).

Plotting ABCDE, A'B'C'D'E', and the line x = -2 has been shown on the graph.

The angles m∠ A and m∠ A' are equal since ABCDE is reflected to make A'B'C'D'E' which makes the two figures congruent. And in congruent figures, the corresponding angles are equal.

The given quadrilateral is not a parallelogram.

According to the statement

We have to find that the whether the quadrilateral is a parallelogram or not.

So, For this purpose, we know that the

A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

From the given information:

The coordinates of the vertices of quadrilateral ABCD are A(-6,-1), B(-5,2), C(-1.-5), and D(0.-2).

Then

To show that the diagonals are bisect each other, we have to find the midpoint of both diagonals and if the midpoint is same then they bisect each other.

So,

Midpoint of AC = Midpoint of BD

Midpoint of A(-6,-1),C(-1.-5)  = Midpoint of B(-5,2),D(0.-2)

( -6-1/2 , -1-5/2) = (-5+0/2 , 2-2/0)

( -7/2 , -6/2) = (-5/2 , 0/2)

And these midpoints are not same then they do not bisect each other and then it is not a parallelogram.

So, The given quadrilateral is not a parallelogram.

The diameter of the gold atom is greater than the diameter of the oxygen atom by 7 x 10^-11 meter

The diameter of a shape (usually a round shape) is a line that divides the shape to equal parts

The diameters are given as:

Diameter of a gold atom = approximately 144 trillionths of a meter

Diameter of an oxygen atom = approximately 0.074 billionths meter

Using a calculator, we convert the above numbers to scientific numbers

So, we have

Diameter of a gold atom = approximately 1.44 x 10^-10 meter

Diameter of an oxygen atom = approximately 7.4 x 10^-11 meter

The number with the higher exponent is greater than the other number

Hence, the diameter of the gold atom is greater than the diameter of the oxygen atom

In (a), we have

Diameter of a gold atom = approximately 1.44 x 10^-10 meter

Diameter of an oxygen atom = approximately 7.4 x 10^-11 meter

Calculate the difference

d = 1.44 x 10^-10 - 7.4 x 10^-11

Evaluate the difference

d = 7 x 10^-11

Hence, the diameter of the gold atom is greater than the diameter of the oxygen atom by 7 x 10^-11 meter

(C) The perimeter of the ΔABC is 9 + √41 units.

A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter.

The vertices of the triangle on the girds are A( - 1, 5 ), B( 4, 5 ), and C( - 1, 1 ).

The distance formula for the length of a line segment is given as:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Therefore,

[tex]AB=\sqrt{(4-(-1))^2+(5-5)^2}=\sqrt{(4+1)^2+0}=5[/tex]

[tex]BC=\sqrt{(-1-4)^2+(1-5)^2}=\sqrt{(-5)^2+(-4)^2}=\sqrt{25+16}\\BC=\sqrt{41}[/tex]

[tex]AC=\sqrt{(-1-(-1))^2+(1-5)^2}=\sqrt{(-1+1)^2+(-4)^2}\\AC=\sqrt{0+16}=4[/tex]

Hence, the length of the sides of the triangle are [tex]5,\sqrt{41},4[/tex] units.

Now, the perimeter of a triangle is the sum of all three sides of the triangle.

Therefore, the perimeter of the triangle ABC is:

P = AB + BC + AC

P = 5 + √41 + 4

P = 9 + √41 units

Therefore, the perimeter of ABC is 9 + √41 units.

We get that the slope of the green line will be 2 / 5 when it is perpendicular to the red line.

We are given that the red line is perpendicular to the green line.

Also, we are given that the slope of the red line is - 5 / 2

m₁ = - 5 / 2

Now, we need to find the slope of green line.

Let the slope of the green line be m₂

We know that, when the lines are perpendicular, then the relationship between their slopes is given by:

m₁ ×  m₂ = - 1

Substituting the values, we get that:

- 5 / 2 × m₂ = - 1

m₂ = - 1 × - 2 / 5

m₂ = 2 / 5

In this question we have a system of two linear equations with two variables, which can be represented on Cartesian plane. By geometry it is known that a line can be constructed after knowing the location of two distinct points.

First, we find two distinct points from each line:

x + y = 7: (7, 0), (0, 7)

- x + y = - 7: (7, 0), (0, - 7)

Second, set each pair of points and construct the lines on a Cartesian plane.

The four sides of the quadrilateral are 9 m,10 m, 11 m and 12 m.

What is a quadrilateral?

A quadrilateral is a four-sided polygon with four angles and four vertices. The term "quadrilateral" comes from the Latin words "quadri," which means "four," and "latus," which means "side."

Let the four sides of the quadrilateral be (x-2), (x-1), x, (x+1).

Then, perimeter = (x-2) + (x-1) + x + (x+1)

i.e., x - 2 + x - 1 + x + x + 1 = 42

i.e., 4x - 2 = 42

i.e., 4x = 42 + 2

i.e., 4x = 44

i.e., x = 11

Hence, the four sides of the quadrilateral are 9 meters, 10 meters, 11 meters and 12 meters.
