What is Volume ?The space occupied inside an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied inside an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
The capacity occupied by a three-dimensional solid shape is known as volume. It is difficult to imagine in any shape, yet it may be compared amongst shapes. For instance, a compass box has a larger volume than an eraser placed inside of it. We split the area into equal square units to get the area of any two-dimensional form. Similar to this, we shall split the volume of solid objects into equal cubical units while calculating it. In the part after this one, let's examine how to determine the volume of various solid forms.
The dimension of the room is 11*11*8 in feet.
so, 11 ft = 11 *2.54*12 = 335.28 cm
And, 8 ft = 8 *2.54*12 = 243.84 cm
Volume of the room is = 335.28 * 335.28 * 243.84 = 27410707.5 [tex]cm\x^{3}[/tex]

If 2x − 2 ≤ f(x) ≤ x2 − 2x + 2 for x ≥ 0, find lim x→2 f(x).
The value of [tex]\lim _{x \rightarrow 2}[/tex] f(x) by Sandwich theorem is 2.
As per the given data the function limits are:
2x − 2 ≤ f(x) ≤ x2 − 2x + 2 for x ≥ 0
Here we have to determine the value of [tex]\lim _{x \rightarrow 2}[/tex] f(x)
Hence by Sandwich theorem:
The sandwich theorem, also known as the squeeze theorem, asserts that if two functions, g (x) and h (x), are squeezed between one another and their respective limits at a given position are both equal to L, then the limit of f (x) at that point is also equal to L.
We can use the theorem to find tricky limits like sin(x)/x at x=0, by "squeezing" [tex]\frac{sin(x)}{x}[/tex] between two nicer functions and using them to find the limit at x = 0.

On solving the provided question we can say that the percentage discount will be equal to 20%
What is percentage?A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

Answer : in California there are 24 volcanoes while in Alaska there are 36 volcanoes.
Step-by-step explanation:
Total number of volcanoes = 60.
40% of the volcanoes where in California.
i.e 100% - 40% = 60%.
60% of the volcanoes were in Alaska.
In California = 40/100 × 60 = 24 volcanoes.

By unitary method 24 students/(64/9) yards squared times 1600 yards squared equals 5400 students.
What is unitary method ?The unit technique is an approach to problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

The process for doing this may be standardized. a single country. anything that has an identity element. (mathematics, algebra) (Linear algebra, mathematical analysis, mathematics of matrices or operators) Its adjoint and reciprocal are equivalent.

24 kids covered an area of 8 ft x 8 ft, or (8 ft x 1 yd/3 ft)2 = [(8/3) yard]2 = (64/9) yd.
The number of students present is calculated by multiplying the number of students per yard, or 24 students/(64/9) yd2, by the area that students cover.

y = 2 + 3*x
Evaluating it, we can see that when you are 12 years old, your uncle will be 38 years old.
How to find the equation for your uncle's age?Let's define the variables: y as your uncle's age and x as your age.
Here we know that your uncle is 2 years older than 3 times your age, so we can write the linear equation:
y = 2 + 3*x
This is the equation we needed to find.
b) If you are 12 years old, then we can write x = 12 in the equation above, then we will get:
y = 2 + 3*12
y = 2 + 36
y = 38
That's the age of your uncle.
