2) What is 18th term in this sequence: 45, 49, 53, 57,

Answers

Answer 1

Answer:

a₁₈ = 113

Step-by-step explanation:

There is a common difference d between consecutive terms

d = 49 - 45 = 53 - 49 = 57 - 53 = 4

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 45 and d = 4, then

a₁₈ = 45 + (17 × 4) = 45 + 68 = 113

Is there a proportional relationship between number of sandwiches and the cost of the order? Explain how you know.
(The picture shows what the relationship is now all I need to find is if it’s proportional or not, and why. Can you help me please? It’s homework, and it’s due in 5 minutes.)

Answers

Answer:

No, there is no proportional relationship

Step-by-step explanation:

The proportional relationship is:

y = kx, which is a special form of linear equation, with zero y-intercept

In the given case we have:

y = 4.5x + 10

This is a linear function but not proportional relationship because it has y-intercept, different than zero

heather spend 2/7 of her money buying presents. she then had €48.65 left how much had she at first?​

Answers

Given :

Heather spend 2/7 of her money buying presents.

She then had €48.65 left.

To Find :

The initial amount of money she had.

Solution :

Let, initial amount she had is €x.

So,

[tex]x - \dfrac{2x}{7} = 48.65\\\\\dfrac{5x}{7} = 48.65 \\\\x = \dfrac{48.65\times 7}{5}[/tex]

x = €68.11

Therefore, initially he had €68.11 .

Nancy has 7 boxes of tomatoes. Each day, she picks another
2
box. How many boxes of
tomatoes will Nancy have in 6 days? Write an equation, complete the table, and then graph to
solve the problem.

Answers

Answer:

19 boxes of tomatoes

Step-by-step explanation:

If she starts with 7 boxes of tomatoes and she picks 2 more each day for 6 days then you can multiply 2 by 6 and get 12 tomatoes then you add the 7 boxes she originally started with and you get 19 boxes of tomatoes.

The number of boxes Nancy had after 6 days is 19, the equation representing the given phrase is y = 2x + 7, and the graph is attached below.

What is graph?

A collection of objects is arranged in a graph, where some object pairings are conceptually "linked." Each pair of connected vertices is referred to as an edge, and the objects are represented by mathematical abstractions known as vertices.

Given:

Nancy has 7 boxes of tomatoes,

Each day, she picks another 2 boxes,

The equation which will represent the above phrase is shown below,

Total number of tomatoes = The number of tomatoes she already had + number of days × each day's tomatoes picked by Nancy,

Assume the total number is y and the number of days is x then,

y = 7 + 2 × x

y = 2x + 7

Put the value of x = 6,

y = 2 × 6 + 7

y = 12 + 7

y = 19

Thus, she has a total of 19 boxes of tomatoes after 6 days.

What is the inverse of the function f(x) = 4x + 8?

Answers

Answer:

h(x) = (1/4)x - 2 which is choice A

Step-by-step explanation:

Replace f(x) with y. Then swap x and y. Lastly, solve for y to get the inverse.

f(x) = 4x+8

y = 4x+8

x = 4y+8

x-8 = 4y

4y = x-8

y = (x-8)/4

y = x/4 - 8/4

y = (1/4)x - 2

h(x) = (1/4)x - 2

Pentagon WFNSC is shown on the coordinate grid. Pentagon WFNSC is dilated with the origin as the center of dilation using the rule (x, y)→(3x, 3y) to create pentagon pentagon W'F'N'S'C'. Which statement is true? Pentagon W'F'N'S'C' is larger than pentagon WFNSC because the scale factor is greater than 1. Pentagon W'F'N'S'C' is larger than pentagon WFNSC because the scale factor is less than 1. Pentagon W'F'N'S'C' is smaller than pentagon WFNSC because the scale factor is less than 1. Pentagon W'F'N'S'C' is smaller than pentagon WFNSC because the scale factor is greater than 1.

Answers

Answer:b

Step-by-step explanation:

 Option A. Pentagon W'F'N'S'C' is larger than pentagon WFNSC because the scale factor is greater than 1.

Transformation of a figure by dilation:  If a point (x, y) is dilated by a scale factor 'k', image point will be given by the rule,

          (x, y) → (kx, ky)

 If k > 1, image point will be larger than its preimage.  If k < 1, image point will be smaller than its image.

Given in the question,

A pentagon WFNSC is dilated following the rule of dilation as,

        (x, y) → (3x, 3y)

Here, k > 3 which shows that the image will be larger than the preimage.

      Therefore, pentagon W'F'N'S'C' will be larger than pentagon WFNSC because the scale factor is greater than 1.

      Hence, Option A will be the answer.

Amy has 20 necklaces in a jewelry box. The probability of reaching into the jewelry box and pulling out a silver necklace is 0.85. What is the probability that Amy will reach in the jewelry box and pull out a necklace that is not silver?

Answers

Answer:

0.15

Step-by-step explanation:

Given

[tex]Necklaces = 20[/tex]

Represent the probability of pulling out silver with p; So:

[tex]p = 0.85[/tex]

Required

Determine the probability of not pulling silver

This question is to test probability complements

And the complement rule of probability states that:

[tex]p + q = 1[/tex]

Where q and p are opposites. In other words:

q = probability of not pulling out silver

Substitute 0.85 for p in [tex]p + q = 1[/tex]

[tex]0.85 + q = 1[/tex]

Make q the subject

[tex]q = 1 - 0.85[/tex]

[tex]q = 0.15[/tex]

Hence, the required probability is 0.15

Step-by-step explanation:

The lines represent the lines of symmetry where the image can be reflected upon. Hence it is reflectional.

The dot in the middle of the image tells us that the image can be rotated about the dot to produce the exact same image. Hence it is rotational.

The answer is both rotational and reflectional.

Answer:

I broke it to phrases. Make sure to read both.

It is rotational symmetry. This is because rotational symmetry means it is able to be rotated, and looks the same. This is true with this figure. The lines demonstrate that it is an equal dimensioned 2D shape.

It is ALSO reflection symmetry because this means it can be split through the center and looks exactly the same, as if it was a reflection. This is true here too because it has the same amount of lines split through the same angle on each side making it equal. You can also see a line already going through the shape, and as you can see if you look at see side it looks equal, like a reflection.

The answer is D.

Write an expression in terms of x to represent the area of parallelogram PQRS

Answers

Answer:

The value of b is 5 if the parallelogram is a rectangle

Step-by-step explanation:

Mathematically, the diagonals of a rectangle are equal in value

Thus, for the given expressions to represent the diagonals of a rectangle, the two must be equal

To get the value of b that makes the two equal, we simply equate the two expressions

We have this as;

10/12(24b/5 - 36/5) = 2/3 (3b + 6)

opening the brackets, we have;

4b - 6 = 2b + 4

4b - 2b = 4 + 6

2b = 10

b = 10/2

b = 5
