The strategy to catch the spider is elaborated out here.
The best strategy for catching the spider after infinitely many steps is to start at one point in the grid and then move in a clockwise spiral, expanding your search area every time you move. As you move, you can use a combination of visual and physical cues, such as vibrations and sound, to detect the spider's presence. This method will ensure that the spider will eventually be caught in a finite amount of time. Additionally, if the spider changes directions, your search will be able to adjust to that change, as you will be able to detect it in the spiral pattern.

What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that the baker is making cookies.
The recipe calls for 1/2 cups of flour and [tex]2\frac{1}{4}[/tex] cups of sugar.
We need to find the flour required to baker for 1 cup of sugar.
Let us form a proportional equation.
x be the flour required for 1 cup of sugar.
[tex]2\frac{1}{4}[/tex] /1/2=1/x
Apply cross multiplication
9/4x=1/2
Divide both sides by 9/4
x=1/2×4/9

The inequality 12n>135+4. 50n represents the situation in which the artist makes a profit. Will the artist make a profit if she sells 15 necklaces? show how you know. Write an inequality to show the number of necklaces, n, the artist must sell to make a profit. Show your reasoning. Enter your answers and your explanation in the space provided. You may also use the drawing tool to help explain or support your answer.
The jewelry artist does not make a profit if she sells 15 necklaces at an art fair .
An inequality to show the number of necklaces, n, the artist must sell to make a profit is
12n - 135 > 4.50n , n > 15 .
We have given that
A jewelry artist is selling necklaces at an art fair.
Cost of rent a booth at the fair = $135
Cost of materials of each necklace= $4.50
Selling price of each necklace = $12
The inequality for the artist's profit is
12n>135+4.50n
where n --> number of necklaces
We have to check that if number of necklaces sold by artist are 15 then she make a profit or not .
For this we plug n = 15 and check the inequality is statisfied or not ,
12×15 > 135 + 4.50×15
=> 180 > 220 , which is not true.
So, the artist does not make a profit if she sells 15 necklaces.
She has profit when selling price is greater than cost price of necklaces.
If we take total number of necklaces are "n".
then, Total cost price of 15 necklaces= $4.50× n
= $4.50n
Total cost payed by artist = $4.50n+$135
Total selling price of 15 necklaces = $12n
Profit if S.P >C.P or $12n > $4.50n+$135
=> 12n - 135 > 4.50n , n > 15
Hence, the required inequality is that
12n - 135 > 4.50n , n > 15 .

The isosceles triangle has a base that measures 14 units. A triangle has a base length of 14. The other 2 sides have a length of y. The value of y, the length of each leg, must be.
For an isosceles triangle has a base that measures 14 units, the length of each leg i.e y must be greater than or equal to 7 .
We have given that
let ABC is an isosceles triangle with base BC and AB = AC
The length of base of isosceles triangle, BC
= 14 units
Let "y" be the length of other side of triangle AB or AC
we have to find the possible length of y for each leg .
Using the Triangle inequality Theorem,
which states that the addition of any two sides of a triangle is greater than or equal to the third side; In symbols form , a + b ≥ c.
We have an isosceles triangle with base 14 cm
so, y + y ≥ 14
=> 2y ≥ 14
=> y ≥ 7
thus, the length of each leg of isosceles triangle must be greater than or equal to 7 units.

The length of the boundary of any closed figure is called its perimeter.
Perimeter is calculated only of 2-dimensional shape, or a 1-dimensional length. This means that shapes like cubes, cones, and cylinders don't have a perimeter.
The perimeter of any shape is calculated by adding up the length of all its sides. A side is referred to as any continuous uninterrupted length of the shape between two points.

the probability of winning at a certain gambling game is 0.1. find the probability of you win for the first time on the third trial ?
the probability of you win for the first time on the third trial is 8.1%
What is probability?
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.
the probability of winning at a certain gambling game is 0.1.
p=0.1
p(x) = (1-p)² *p
= 0.81*0.1

one million photons are detected. what is the expected number of photons in a 1- mmmm -wide interval at xx
The expected number of photons are [tex]N=1[/tex] × [tex]10^{3} m^{2}[/tex].
What are photons?
To put it simply, photons are basic subatomic particles that carry the electromagnetic force (and so much more). The photon is also the "quantum," or basic unit, of electromagnetic radiation.
Photons are all around us: Photons make up the light coming from the screen you're looking at, the X-rays doctors use to see bones, the radio in a car that sends out its signal, and the magnets on a refrigerator that support themselves.
Given: Total number of photons = 1 million
The graph represents the probability density of a photon being found (detected) along the horizontal x- axis.
Now, checking the graph, we will find that:
At x = 0.5, the probability of finding a photon is 1.
To get the probability density at 1 mm wide at the given x value, we will simply multiply the probability with the area under curve as follows:
[tex]P(x=0.5)[/tex] × area under curve
= [tex]1[/tex] × [tex]1[/tex] × [tex]10^{-3} m^{2}[/tex]
Now, we will get the expected number of photons as follows:
N = number of photons × area under curve
[tex]N=1[/tex] × [tex]10^{6}[/tex] × [tex]1[/tex] × [tex]10^{-3}[/tex]
[tex]N=1[/tex] × [tex]10^{3} m^{2}[/tex]

Rate of Return = [?] %
Give your answer as a percent rounded to the
nearest tenth.
The rate of return of the Stock A, purchased for $15 per share and sold for $340, with a commission of the sale of $6, is given as follows:
11.3%.
How to calculate the Rate of Return?The Rate of Return is calculated as the different between the current value of the stock and the initial value of the stock, divided by the initial value of the stock.
20 shares were purchased at a value of $15 per share, hence the initial value of the stock in this problem is given as follows:
Initial value = 20 x 15 = $300.
The stock was then sold for $340, with a commission of $6, hence the current value of the stock is of:
Current value = 340 - 6 = $334.
Then the rate of return is calculated as follows:
Rate of return = 34/300 = 0.113.

c. The discount price of a l
a hat is $38. What is the regular price? Today, everything at the store is on sale. The store offers a 20% discount.
Answer:
the hat is $47.50.
Step-by-step explanation:
To determine the regular price of the hat, you can use the formula for calculating the sale price of an item, which is:
regular price * (1 - discount percentage) = sale price
In this case, we can set up the equation as follows:
regular price * (1 - 0.20) = $38
Solving for the regular price, we get:
regular price = $38 / (1 - 0.20)
regular price = $38 / 0.80
regular price = $47.50
Therefore, the regular price of the hat is $47.50.
