Consider the tile pattern below. Completely describe what figure 100will look like. How many tiles will be in figure 100? Explain how you know
Answers
Answer:
101 up on the left
100 up on right
6 across the bottom
Step-by-step explanation:
their is always six along the bottom
up on the right is whateve number the figure is it increase one everytime
101 up on the left because figure one stats with 2 and from their one is added
The solution is
a) The figure will have 100 rows of 6 tiles and 1 row having 1 tile
b) The number of tiles in figure 100 will be 601 tiles
What is Arithmetic Progression?
An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the figure 100 be represented as = a₁₀₀
Let the number of tiles in the first figure be a₁
The value of a₁ = 7 tiles
Let the number of tiles in the second figure be a₂
The value of a₂ = 13 tiles
So , the common difference of the arithmetic sequence is d
d = second term - first term
d = 13 - 7
d = 6
Now , the value of figure a₁₀₀ is calculated by the formula
Tn = a + (n - 1) d
Substituting the values in the equation , we get
a₁₀₀ = 7 + ( 100 - 1 ) 6
a₁₀₀ = 7 + ( 99 x 6 )
a₁₀₀ = 7 + 594
The value of a₁₀₀ = 601
Therefore , the figure will have 100 rows of 6 tiles and 1 row having 1 tile
And , the total number of tiles in the figure is 601 tiles
Hence , The figure will have 100 rows of 6 tiles and 1 row having 1 tile and
the number of tiles in figure 100 will be 601 tiles

43. Can you place ten lumps of sugar in three empty cups so that
there is an odd number of lumps in each cup?
Answers
Answer: No.
Step-by-step explanation:
We have 10 lumps of sugar, and we want to divide them into 3 cups, in such a way that there is an odd number of lumps in each cup.
This only can happen if we have 3 odd numbers such that the addition is equal to 10.
Now 10 is an even number, remember that even numbers can be written as:
2*k
where k is an integer number.
And odd numbers can be written as:
2*n + 1
where n is an integer.
Then we have 3 odd numbers, let's call them:
(2*n + 1), (2*k + 1) and (2*p + 1).
Now let's add them:
(2*n + 1) + (2*k + 1) + (2*p + 1).
2*(n + k + p) + 1 + 1+ 1
2*(n + k + p) + 2 + 1 =
2*(n + k + p + 1) + 1.
Now, the number n + k + p + 1 is an integer number, let's call it X, then we have that the addition of the 3 odd numbers is:
2*X + 1
This is an odd number
So for any 3 odd numbers that we add together, the result will always be an odd number.
Then is impossible to add 3 odd numbers and get 10 as the result (Again, 10 is an even number).
Then is not possible to have an odd number of lumps in each cup.

Charlie and Clare are playing a number-guessing game. Charlie picked two numbers between 1 and 5. To win the game, Clare must guess both his numbers in three tries. Her guesses, simulated using a random-number generator, are shown in the table. If Charlie’s numbers are 1 and 3, what is the experimental probability that Clare won?
Answers
The experimental probability is 3/10 that Clare won if Charlie's numbers were 1 and 3
What is probability?The probability is defined as the possibility of an event is equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Charlie picked two numbers between 1 and 5
So the numbers should be 2, 3, and 4
There is the number of favorable outcomes is 3
To win the game, Clare must guess both his numbers in three tries
The experimental probability that Clare won if Charlie's numbers were 1 and 3 = P(E)
There are 10 trials given
There are total number of possible outcomes is 10
So the required experimental probability P(E) = favorable outcomes/total outcomes
⇒ P(E) = 3/10
Hence, the experimental probability is 3/10 that Clare won if Charlie's numbers were 1 and 3.

If x-2=2^(2/3) + 2^(1/3), show that x3 - 6x3 + 6x-2=0
Answers
so x - 2 = 2^(2/3) + 2^(1/3)
=(x-2)^3 = [2^(2/3)+2^(1/3)]^3
use (a-b)^3= a^3 - b^3 - 3ab(a-b)
and (a+b)^3= a^3 + b^3 + 3ab(a+b) formulae.
or x^3 - 8 - 6x(x-2) = 2^2 + 2^1 + 3*[2^{(2/3)+(1/3)}[2^(2/3)+2^(1/3)
or x^3 - 8 - 6x^2 + 12x = 4 + 2 + 6(x-2)
or x^3 - 8 -6x^2 + 12x = 6 + 6x - 12
or x^3 - 6x^2 +6x = 2

The width of a rectangle is 2 units shorter than half the length x write an expression that represents the perimeter of the rectangle
Answers
Answer:
3x-4
Step-by-step explanation:
Length = x
width = 2 units shorter than half the length x
width = x/2 - 2
For rectangle
perimeter = 2(length + width)
Perimeter for given rectangle = 2(length + width)
Perimeter for given rectangle = 2(x + x/2 - 2) = 2x + 2x/2 -4
Perimeter for given rectangle = 2x+x -4 = 3x -4
Expression that represents the perimeter of the rectangle is 3x-4.

Jeff and Cameron are arguing about which one of them is faster. Jeff says "I can run 777 kilometers per hour!" and Cameron says "I can run 100100100 meters per minute!"
Answers
Answer:
Jeff is faster
Step-by-step explanation:
kilometers are faster than meters
and 7 kilometers is 700 meters
so 100 meters isn't fast enough compared to Jeff's speed
Jeff is faster than Cameron as his average speed is more than that of Cameron's average speed.
How to calculate the average speed of a body?The average speed of a body is the ratio of the distance covered by the body to the time it takes to cover that distance.
How to solve the given question?In the question, we are given that Jeff says that he can run 7 kilometers per hour while Cameron says that he can run 100 meters per minute.
We are asked to tell who is the faster among them.
We need to know that, 1 kilometer = 1000 meters, and 1 hour = 60 minutes.
Jeff's average speed = 7 km/hr. = 7km/1hr = (7*1000) m / (1*60) min
or, Jeff's average speed = 7000/60 meters per minute = 116.67 meters per minute.
We are given that Cameron's average speed is 100 meters per minute.
So, we can say that Jeff is faster than Cameron, as
Jeff's average speed > Cameron's average speed.
∴ Jeff is faster than Cameron as his average speed is more than that of Cameron's average speed.

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 8% vinegar, and the second brand contains 13% vinegar. The chef wants to make 270 milliliters of a dressing that is 9% vinegar. How much of each brand should she use
Answers
Answer:
Amount of 8% vinegar = 216 mL
Amount of 13% vinegar = 54 mL
Step-by-step explanation:
First, of all, let x be the amount of 8% vinegar used
Since, the scientist needs 270 mL of vinegar, then;
Let 270 - x be the amount of 13% vinegar used
Now, we are told that she needs 270 mL of a 9% vinegar.
This means that;
8%x + 13%(270 - x) = 9%(270)
Simplifying this gives;
0.08x + 0.13(270 - x) = 0.09 × 270
Expanding the bracket gives;
0.08x + 35.1 - 0.13x = 24.3
0.13x - 0.08x = 35.1 - 24.3
0.05x = 10.8
x = 10.8/0.05
x = 216 mL
Thus, she will need to use 216 mL of the 8% vinegar.
Since 270 - x is the amount of 13% vinegar used , then;
the amount of 13% vinegar = 270 - 216 = 54 mL
Justin wants to cover the top of a circular swimming pool to keep insects out of the pool. If the diameter of the pool is 20 feet, what will be the area of the top of the cover (the portion of the cover that covers the surface of the pool)?
Answers
Answer: The area is approximately 314 ft^2
Step-by-step explanation:
Well if the diameter is 20 feet then the radius will be 10 because the radius is half the diameter, and to find the area of a circle, you use the formula
A= [tex]\pi r^{2}[/tex] where A is the area and pi times the radius squared.
We will represent pi by 3.14
A= 3.14* 10^2
A= 3.14 * 100

Steven babysits and y represent the amount he charges.
The equation is y =
Answers
Answer:
y = 6.75x
Step-by-step explanation:
These 2 pieces of information can be used to create 2 points on the graph, where x is the number of hours and y is the amount he charges:
(5, 33.75) and (8, 54) are the 2 points
Use rise/run (y2 - y1) / (x2 - x1) to find the slope
(54 - 33.75) / (8 - 5)
20.25/3
= 6.75
Now, plug this and another point into y = mx + b to find b, the y intercept
54 = 6.75(8) + b
54 = 54 + b
0 = b
So, the equation is y = 6.75x
