A sequence of patterns is made from circular tiles and square tiles. Here are the first three patterns in the sequence: a) How many square tiles are needed to make Pattern Number 7? [2 MARKS] b) How many circular tiles are needed to make Pattern Number 20? [2 MARKS] c) When the pattern number is odd, the total number of tiles (SQUARE & CIRCULAR) needed to make the pattern: A - will always be even | B - will always be odd | C - could be even or odd | [2 MARKS] !! PLEASE ANSWER ALL OF THE QUESTIONS !!

Answers

The patterns of tiles do not follow an arithmetic sequence or geometric sequence

When the pattern number is odd, the total number of tiles (SQUARE & CIRCULAR) needed to make the pattern will always be odd

The square tiles needed to make Pattern Number 7?

From the question, we have the following pattern:

Pattern 1: 1 square and 8 circlesPattern 2: 4 squares and 12 circlesPattern 3: 9 squares and 16 circles

The number of square tiles is calculated using:

Tn= n²

So, we have:

T₇ = 7²

T₇ = 49

Hence, 49 square tiles are needed in pattern 7

The circular tiles needed to make Pattern Number 20

The number of circular tiles is calculated using:

Tn= 4n + 4

So, we have:

T₂₀= 4 * 20 + 4

T₂₀= 84

Hence, 84 circular tiles are needed in pattern 20

c) The conclusion on odd pattern number

Using the computations in (a) and (b), we have:

The total number of tiles in odd pattern number is always odd

A paper cup in the shape of a cone is used to get water from a water cooler. It has a height of 3 inches and a diameter of 22 inches
What is the lateral surface area of the paper cup to the nearest square Inch?
OA 15 square Inches
OB.
19 square Inches
ОС.
14 square Inches
OD. 18 square Inches

Answers

We will see that the lateral surface area of the cone is 14 square inches.

How to find the lateral surface area?

We know that for a cone of height H and radius R, the lateral surface of the cone is:

S = 3.14*R*H

In this case, we know that eh height is 3 + 5/8 inches, and the diameter is 2 + 1/2 inches. Remember that the diameter is twice the radius, then:

R = (2 + 1/2) in = (1 + 1/4) in

Replacing that on the surface equation, we will get:

S = 3.14*( (1 + 1/4) in)*(3 + 5/8)in = 14 in^2

Answers

Dilating the blue figure to create the red figure ensures that both figures have different sizes

The correct center of dilation is (d)

How to determine the center of dilation?

The center of dilation influences the position of the image of the dilated figure.

For figure 1, the center of dilation would ensure that the red figure is to the left of the blue figureFor figure 2 and 3, the center of dilation would ensure that the red and the blue figure have the same vertexFor figure 4, the center of dilation would ensure that both triangles have the same center

The 4 diagrams show that both figures have the same center

What is the median of the data set represented by the dot plot?

Enter the answer in the box.

A number line with line with two dots above the number 10, one dot above the number 12, one dot above the number 13, one dot above the number 14, one dot above the number 15, one dot above the number 18, and two dots above the number 19.

Answers

Answer:

Median is 14

Step-by-step explanation:

The median is the middle number (or average of middle two numbers if data set has even number of elements) of the data set.

According to the graph, the data set has 9 elements.

The 5th number in the set is the median, which is 14

Answer:

Step-by-step explanation:

Step-1: Prepare a table that represents the number of dots above a specific number:

[tex]\text{Dots above 10}: || \\ \text{Dots above 12}: | \\ \text{Dots above 13}: | \\ \text{Dots above 14}: | \\ \text{Dots above 15}: | \\ \text{Dots above 18}: | \\ \text{Dots above 19}: ||[/tex]

Step-2: Put the values in ascending or descending upon your choice:

[tex]10, 10, 12, 13, 14, 15, 18, 19, 19[/tex]

Step-3: Determine wether the total number of digits in the data is even or odd. This will help us find the median.

[tex]\text{9 digits in total}\\\\\text{The number of digits is \underline{odd}}[/tex]

Since the number of digits is odd, we will use the formula (a + 1)/2

(where a is the number of digits in the data)

Step-4: Substitute the number of digits in the formula.

⇒ (a + 1)/2th

⇒ (9 + 1)/2th

⇒ (10)/2th

⇒ 5th digit is median

Step-5: Look for the 5th digit in the data. That digit is your median.

[tex]10, 10, 12, 13, \underline{\underline{14}}, 15, 18, 19, 19[/tex]

The median of the dot plot is 14.

Which of the following shapes can be a cross section of a cylinder?

Answers

Answer:

Below

Step-by-step explanation:

The second ( Oval) (The cross-section of a slanted plane through curved body of the cylinder)

The third (Circle). ( The cross section of a plane parallel to the base)

The fifth (Rectangle) (The vertical cross section of a plane through the diameters of the top and bottom of the cylinder.).

The shapes can be used are oval, circle and rectangle.

What is Geometry?

Geometric shapes are defined as figures closed by a boundary which is made by combining the definite amount of curves, points, and line segments. Each shape has a unique name such as circle, square, triangle, rectangle, etc. In real life, we are surrounded by various basic geometric shapes, like the slice of a pizza is in the shape of a triangle, doors or windows are in the shape of a rectangle, and many more.

Types of Geometric Shapes

In geometry, when an object or a shape is not connected with both ends, it is considered an open geometric shape. When an object or a shape is connected with both ends it is considered a closed geometric shape. There are two types of geometric shapes, classified as:

Two-dimensional: These are 2D shapes that have only the x-axis and y-axis. They are flat structures with 2 dimensions. For example, triangle, square, rectangle, etc.Three-dimensional: These are 3D shapes that have an x-axis, y-axis, and z-axis. The z-axis represents the height of the object. They are solid structures with 3 dimensions. For example, cube, cuboid, etc.

First, oval can be used as the cross-section of a slanted plane through curved body of the cylinder.

Then, circle (plane parallel to base)

Then, rectangle the vertical cross section of a plane through diameters.

Answer:

3. Object C.

Step-by-step explanation:

The inertia of an object is the measure of the force required to set it in motion. For two objects to have the same motion, the one with the greater mass will require a proportionately greater force to achieve the same motion.

Object C, with a mass of 1,250,000 grams (1,250 kg) will have the greatest inertia.

Natalie is playing a game using a fair coin. Contestants win the game if the fair coin lands tails up. The theoretical proabaility that the coin will lamd tails is ? If 250 contestants play the game, about of them are expected to win

Answers

The theoretical probability of landing on tails is P = 0.5, and out of the 250 contestants, around 125 will win the game.

About how many contestants will win?

The coin has two possible outcomes, so if it is a fair coin, the probability for each of the outcomes will be 0.5 (this is the theoretical probability for a fair coin, where all the outcomes have the same probability).

Now, we know that a person wins if the coin lands tails up, and the probability of landing on tails is 0.5

Then, for a sample N, we can expect that about 0.5*N of the participants win.

In this case, the sample is 250, then we can expect that:

0.5*250 = 125

Around 125 of the contestants win the game

Which inequality is shown in this graph?

(-2, 2)
-5
5
(0, -2)

Answers

The inequality of the graph is a linear inequality

The inequality shown in the graph is y > -2x -2

How to determine the inequality?

The points on the graph are given as:

(x,y) = (-2,2) and (0,-2)

The slope (m) is calculatedusing:

m = (y2 - y1)/(x2 - x1)

This gives

m =(-2 - 2)/(0 + 2)

Evaluate

m = -2

The equation is then calculated as:

y = m(x - x1) + y1

This gives

y = -2(x - 0) -2

y = -2x -2

The upper part of the graph is shaded with a dotted line, so the inequality is a greater than inequality

The equation becomes

y > -2x -2

Hence, the inequality shown in the graph is y > -2x -2
