A percentage is a way to describe a part of a whole. x is 133¹/₃% of y. The correct option is D.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that 15% of x equals 20% of y. Therefore, we can write,
15% of x = 20% of y
(15/100) × x = (20/100) × y
Multiply both the sides of the equation by 100,
(15/100) × x × 100 = (20/100) × y × 100
15x = 20y
x/y = 20/15
Divide both the sides of the equation by 5,
x/y = 4/3
Now, the percentage of x that is y is,
Percentage = (x/y) × 100%
= (x/y) × 100%
= (4/3) × 100%
= 133.33%
= 133 ¹/₃ %
Hence, x is 133.33¹/₃% of y.

A trampoline park has a trampoline that is 8 yards wide and 12 yards long. Approximate the distance (in yards) between opposite con
nearest tenth.
The distance between the opposite sides of the trampoline can be found to be 14. 42 yards
How to find the distance ?To find the distance between the opposite sides of the trampoline, we are essentially finding the diagonal length. We can use the Pythagorean theorem to do this by dividing the trampoline into two right triangles.
The distance between the opposite sides would then be:
c ² = a ² + b ²
c ² = 8 ² + 12 ²
c ² = 64 + 144
c ² = 208
c = √ 208

(a) Determine a cubic polynomial with integer coefficients which has $\sqrt[3]{2} \sqrt[3]{4}$ as a root. (b) Prove that $\sqrt[3]{2} \sqrt[3]{4}$ is irrational.
\(\sqrt[3]{2}+\sqrt[3]{4}\) is the root of the cubic polynomial \(x^3-6 x-6\) .
What is cubic polynomial?A cubic function in mathematics is a function with the formula: f(x)=ax3+bx2+cx+d where the variable x has real values, the coefficients a, b, c, and d are complex integers, and a, a, and 0 are equal to zero. In other words, it is a real function as well as a polynomial function of degree three. The set of real numbers is specifically the domain and the codomain. All odd-degree polynomials have at least one real root, while cubic functions have one to three real roots (which may not be distinct).
A cubic function's graph always has one inflection point. It might have a local minimum and local maximum as its two essential points. A cubic function is monotonic if it is not.
Let \(r=\sqrt[3]{2}+\sqrt[3]{4}\)
\(\text { Then, since }(a+b)^{\wedge} 3=a^{\wedge} 3+3 a^{\wedge} 2 b+3 a b^{\wedge} 2+b^{\wedge} 3=a^{\wedge} 3+3 a b *(a+b)+b^{\wedge} 3\)
\(\begin{aligned}\mathbf{r}^{\wedge} 3 &=\left(\frac{3}{2} \sqrt{2}+3 \cdot \sqrt[3]{2} \cdot \sqrt[3]{4} \cdot(\sqrt[3]{2}+\sqrt[3]{4})+(\sqrt[3]{4}) 3=\right.\\&=2+3 \cdot \sqrt[3]{8} \cdot(\sqrt{2}+\sqrt{4})+4=2+3 * 2 * r+4=6+6 r .\end{aligned}\)
\(\text { It means that } r=\sqrt[3]{2}+\sqrt[3]{4} \text { is the root to this equation }\)
\(r^3-6 r-6=0 .\)

What is a subspace?A subspace of a vector space is a portion of that space that meets the three criteria of closure under addition, closure under scalar multiplication, and the presence of the zero vector. If two vectors from the subspace are added, the resultant vector will still be in the subspace because of closure under addition. If a vector from the subspace is multiplied by any scalar, the resultant vector will still be in the subspace, according to the concept of closure under scalar multiplication.
The conditions of a subspace are: closure under addition, closure under scalar multiplication, and contains the zero vector.
For all the options we have:
A: The 3 x 3 matrices in reduced row-echelon form (A): As this subset is not closed under addition, M3(R), it is not a subspace of M3(R).
B. The 3 x 3 matrices with all zeros in the third row: Due to its closure under addition and scalar multiplication as well as the presence of the zero vector, this subset is a subspace of M3(R).
C. The diagonal 3 x 3 matrices: This subset, which is closed under addition and scalar multiplication and contains the zero vector, is a subspace of M3(R).
D. The invertible 33 matrices: Because this subset is not closed under addition, M3(R), it is not a subspace of M3(R).
E. The 3 x 3 matrices that are not invertible Due to the fact that it is not closed under scalar multiplication, this subset is not a subspace of M3(R).

0.00220462g = 1 pound
1,500,000g = x
Cross multiply
0.00220462x = 1,500,000
x = 1,500,000/0.00220462
x = 680,389,364.15

John spent 80% of his money and saved the rest. Peter spent 75% of his money and saved the rest. If they saved the same amount of money, what is the ratio of John’s money to Peter’s money? Express your answer in its simplest form.
The ratio of John's money to Peter's money is 5/4. This means if John has a total amount of 5 then Peter will have a total of 4 as his amount.
Let's assume John has 'x' amount of money, Peter has 'y' amount of money, The money John saved is 'p' and the money Peter saved is 'q'
So,
p = x - 80x/100 (equation 1)
q = y - 75y/100 (equation 2)
According to the given question, the amount John saved is equal to the amount Peter saved. Hence, we can equate equations 1 and 2.
p = q
x- 80x/100 = y - 75y/100
x - 0.8x = y - 0.75y
0.2x = 0.25y
x = 0.25y/0.2
x/y = 0.25/0.2
x/y = 25/20
x/y = 5/4

TRUE / FALSE. roofs having a span of 40 feet or less and a pitch of ? or greater, and roofs having a span of more than 40 feet and a pitch of 1/4 or greater are considered to be pitched.
The statement is true. Roofs with a span of 40 feet or less and a pitch of ? or greater, as well as roofs with a span of more than 40 feet and a pitch of 1/4 or greater, are considered to be pitched.
In roofing terminology, the pitch refers to the steepness or slope of a roof. A pitched roof has a slope that allows water to drain efficiently. The pitch is typically measured as a ratio of vertical rise to horizontal span.
According to the statement, roofs with a span of 40 feet or less and a pitch of ? (undefined or not specified) or greater are considered to be pitched. This means that as long as the roof has a certain degree of slope or steepness, it is categorized as a pitched roof.
Similarly, roofs with a span of more than 40 feet and a pitch of 1/4 or greater are also considered to be pitched. In this case, the requirement for a minimum pitch of 1/4 (or a steeper slope) applies to roofs with a larger span.
The classification of roofs as pitched or not pitched depends on their span and the minimum pitch requirements specified. Roofs that meet the specified criteria for span and pitch are considered to be pitched roofs.
