The expression 48s represents the number of scarves (s) and its per unit (48).
What is an expression?An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Given that, Emiko makes shibori scarves and sells them for $48 each on a website for handmade goods.
Here, the expression 48s represents the total price of buying s scarves
We need to tell what 48s mean,
So,
48s here is the total cost for buying s scarves,
That mean, if we buy s scarves we will have to pay $48s
Similarly, if we will buy 4 scarves, we will pay = 48 × 4 = $192
For 10 scarves, we will pay = 48 × 10 = $480
Therefore, we can say $48 is the unit price of the scarf.
Hence, the expression 48s represents the number of scarves (s) and its per unit (48).

2020 cans are recycled.
What percent of cans are recycled?
In the United States, 65% of cans are recycled.
What is the percentage?A number or ratio that can be expressed as a fraction of 100 is called a percentage. Divide the number by its whole number and multiply it by 100 if we have to figure out the percentage of that number. Consequently, the percentage represents one part per hundred.
Given In the United States, 13 out of every 20 cans are recycled.
total cans = 20
recycled cans = 13
percent of recycled can = 100*recycled cans/total cans
percent of recycled can = 100*13/20
percent of recycled can = 60%

A large equilateral triangle pyramid stands in front of the city's cultural center. Each side of the base measures 50 feet and the slant height of each lateral side of the pyramid is 40 feet.
A painter can paint 100 square feet of the pyramid in 18 minutes.
How long does it take the painter to paint 75% of the pyramid?
Enter your answer, rounded to the nearest tenth, in the box.
Answer:
Step-by-step explanation:
The lateral surface area of the pyramid can be found using the formula for the area of an equilateral triangle:
A = (s^2 * √3) / 4
where s is the length of one side of the equilateral triangle base.
For this pyramid, s = 50 feet
A = (50^2 * √3) / 4 = (2500 * √3) / 4 = 1250 * √3 ≈ 2129.28 ft^2
The total surface area of the pyramid can be found by adding the area of the base to the area of the lateral surface:
A = base area + lateral surface area
A = (side length^2 * √3) / 4 + (3 * triangle area)
A = (50^2 * √3) / 4 + (3 * (50^2 * √3) / 4)
A = 2500 * √3 + 3750 * √3 ≈ 5884.28 ft^2
To paint 75% of the pyramid, the painter needs to paint 75% * 5884.28 ft^2 = 4413.71 ft^2
Since the painter can paint 100 ft^2 in 18 minutes, he can paint 4413.71 ft^2 in 4413.71 / 100 * 18 minutes ≈ 786.96667 minutes
Rounding to the nearest tenth, the painter will take 786.967 minutes to paint 75% of the pyramid, which is approximately 13.1 hours.

By the given explanation it is proven that ∠1 and ∠3 are supplementary from this, it has proven the Consecutive Interior Angles theorem.
Consecutive Interior Angles theorem:According to the consecutive interior angle, if a transversal intersects two parallel lines each pair of consecutive interior angles is supplementary, meaning that the sum of the consecutive interior angles equals 180°
Here we have
Line p and line q are two parallel lines and line 't' is a transversal on Line p and line q
Theorem:
When a transversal intersects two parallel lines, each pair of consecutive interior angles is supplementary i.e added up to 180°.
We can prove the above theorem as follows
Given p║q
Let's take angles 4 and 5 on line 'p' as shown below
Here ∠4 + ∠3 = 180° [∵ pair of linear angle ]
Now substitute ∠1 in place of ∠4
=> ∠1 + ∠3 = 180° [ ∵ Corresponding angles ∠1 and ∠4 are equal ]

The expressions that can be used to find the area of the shaded portion of the circle are 9²·π - (2 · 13.5π ) and 2/3 · 9²·π
How to determine which expressions can be used to find the area of the shaded portion of the circle?Since the whole circle has a radius of 9 inches. The area of the whole circle will be 9²·π square inches (Remember: Area of circle = πr²)
Also, the area of a single section of the circle is equal to 13.5π square inches.
We can get the area of the shaded portion (blue ones) by subtracting the area of the unshaded portion (white ones) from the area of the whole circle. That is:
9²·π - (2 * 13.5π )
Notice that we have 2 unshaded (whites)
Also, there 4 shaded portions out of the whole 6. We can write:
area of shaded portions = 4/6 · 9²·π = 2/3 · 9²·π

How to determine which equation can be used to solve for x?Angle geometry is a branch of mathematics that deals with the study of angles and their properties in two-dimensional figures such as circles, triangles, and polygons.
In the diagram, since vertically opposite angles are equal. Thus, we can say:
∠UTW = ∠VTZ
90 - 52 = (12x - 10)°
38 = 12x - 10
12x = 38 + 10
12x = 48

9 miles for every 1/2 hour and 6 miles for every 20 minutes tell whether the missing values are equivalent and justify
9 miles for every ½ hour and 6 miles for every 20 minutes can be considered equivalent because they represent the same speed, just measured in different units.
To see this, we can convert the units to a common unit, such as miles per hour.
First, let's convert the 6 miles in 20 minutes to miles per hour:
[tex] \frac{6}{20} \times 60[/tex]= 18 miles/hour
Next, let's compare this speed to the 9 miles per ½ hour:
[tex] \frac{9}{ \frac{1}{2} } = \frac{9}{ \frac{1}{2} } \times \frac{1}{ \frac{1}{2} } = 18[/tex]

The dimensions that will maximize the enclosed area are 125 meters by 250 meters
What dimensions will maximize the enclosed area?Represent the dimensions with x and y
So, we have the following equations
Perimeter = 4x + 2y = 1000
Area = 2xy
So, we have
