The percentage of Venus's year to mercury's year is 39.1%
What is percentage?A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction - three for the price of one! To change the percentage to a fraction, just put the percentage number in the numerator and 100 in the denominator.
Venus year is 88 earth days and mercury is 225 earth days.
To find the percentage of venus's year to mercury's we divide the Venus's year by mercury and multiply by 100
Then , 88/225 ×100 = 39.1 %
Therefore Venus length of year is 39% of mercury's year.

What is cucumber ?
Cucumber is a type of vegetable that belongs to the cucurbit family, which also includes melons, squash and gourds. They are typically long, cylindrical in shape, and have a green skin that is typically eaten raw.
The proportion of the garden planted in cucumber is 1/3 of the vegetable part of the garden. To find out what proportion of the entire garden is planted in cucumber, we can use this proportion and multiply it by the proportion of the garden that is planted in vegetables.
Half of the garden is planted in vegetables, so the proportion of the garden planted in vegetables is 1/2.
1/3 of the vegetable part of the garden is planted in cucumber, so the proportion of the garden planted in cucumber is ,
(1/2) x (1/3) = 1/6
So, 1/6 of the whole garden is planted in cucumber.

The probability of events A
and B is
P(A)=1/2
P(B)=1/3
P(A∩B)=1/4.
What is the value of P(A or B)?
Enter your answer as a fraction, like this: 4/25
Answer: 2/3
Step-by-step explanation:
To find the probability of A or B, we can use the formula: P(A or B) = P(A) + P(B) - P(A ∩ B)
Plugging in the given values:
P(A or B) = 1/2 + 1/3 - 1/4
To solve this, we must find a common denominator in order to add the fractions:
P(A or B) = 3/6 + 2/6 - 1/6
Simplifying:
P(A or B) = 4/6 = 2/3
So the value of P(A or B) is 2/3

Two torage hed are to have the ame area. One i quare and one i rectangular. The rectangular hed i 3 meter wide and 12 meter long
By using the area of the square formula, it can be concluded that the side of the square shed is 6 meters.
The area of a square or a rectangle can be defined as the number of square units needed to fill it.
Area of a Square = side × side = side²
Area of a rectangle = width x length
Area of the square = area of the rectangle
Rectangle width = 3 meter
Rectangle length = 12 meter
To find the side of the square shed, we can do the following:
Area of the square = Area of the rectangle
side² = width x length
= 3 x 12
= 36
side = √36
= 6
Thus the side of the square shed is 6 meters.

Can a negative number be an exponential function?.
Yes, it is possible for a negative number to be an exponential function.
The number of times a number is multiplied by itself is indicated by the positive exponent, as we are aware. In contrast, the negative exponent indicates how many times the base number must be divided. The negative exponent, in other words, indicates how many times the reciprocal of the base must be multiplied. 3-2 is a prime example of a negative exponent.Two negative exponents can be multiplied together in the same way as two numbers. Since we are aware that negative exponents can be reduced to fractions, simplifying negative exponents is simple. Converting the negative exponents to their fractional form is the first step in multiplying negative exponents, after which the procedure is the same as multiplying two fractional numbers.

The correct statements describing the process of converting z = 2 + 3i to polar coordinates using technology are:
Write the complex number as a point in the complex plane: (2, 3i)
Substitute a = 2 and b = 3 for the real and imaginary parts respectively.
Using radians for θ, record the result as r = 3.606 and θ = 0.983 as your answer in polar coordinate form: (3.606, 0.983).
To convert a complex number in the form of z = a + bi to polar coordinates using technology, we can use the following steps:
Write the complex number as a point in the complex plane, with the real part as the x-coordinate and the imaginary part as the y-coordinate.
Substitute a for the real part and b for the imaginary part.
Using the Pythagorean theorem, we can find the distance from the origin to the point, which is the magnitude or modulus of the complex number, represented by r.
Using the tangent function, we can find the angle of the point from the positive x-axis, which is the argument or phase of the complex number, represented by θ.
Record the result in polar coordinates as (r, θ), where r is the magnitude and θ is the argument, given in radians.
It's also worth noting that polar coordinates can also be represented in the form of (r, θ ) or (r, arg(z)) or (r, angle(z))

To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this?
Henry could only see one line since both lines had the same slope, which means that the graphs of both equations will be identical and hence overlap.
Identify the linear equation?Linear equations in a system 3x + 2y = 4, and 9x + 6y = 12
We must demonstrate why Henry could only make out one line when he plotted the equations 3x-2y=4 and 9x-6y=12 on a graph.
Take the provided linear equation system into consideration.
3x - 2y = 4 ................(1)
9x - 6y = 12 ..................(2)
Due to the fact that equation (2) is a multiple of equation (1), 3 (3x - 2y = 4) = 9x - 6y = 12
The slopes of the provided equations are also same.

By applying a reflection over the y-axis to the coordinates of the image coordinates include the following:
(x, y) → (-x, y)
Coordinate M = (-4, 4) → Coordinate M' = (-(-4), 4) = (4, 4).
Next, we would apply a reflection over the x-axis to the above coordinates as follows:

How do you write greater than 4?.
To show that one value is greater than another, use the "greater than" symbol (>). It can be used to express a comparison between two values in mathematical operations, programming, and other forms of notation.
For instance, the "greater than" symbol can be used to compare integers in mathematical operations. For instance, you would write "x > y" to indicate that x is greater than y. This can alternatively be understood as "x exceeds y."
Other comparison symbols, such as "less than," "greater than," and "less than or equal to," can be used in addition to the "greater than" symbol. These symbols can be used to describe many forms of value comparisons in programming and mathematical processes.
The word "greater than" is represented by the symbol ">," therefore to write "greater than 4" you would write ">4".

ZA and B are vertical angles. If m/A= (2x +20)° and m/B = (3x + 1)°,
then find the value of x.
Answer:
The value of x is -19.
Step-by-step explanation:
Given that ZA and B are vertical angles and m/A = (2x +20)°, and m/B = (3x + 1)°, we know that ZA and B are congruent, meaning they have the same measure. We can set the two given equations equal to each other: m/A = (2x + 20)° = m/B = (3x + 1)°. Then, by isolating x on one side of the equation, we subtract 20 from both sides of the equation, then subtract 2x from both sides of the equation, which gives us x = -19, thus the value of x is -19.
Answer:
x = 19
Step-by-step explanation:
since vertical angles are equal we can set the value of angles A and B equal and solve for 'x'
2x + 20 = 3x + 1
20 = x + 1

The statement about the relationship of the data in the table is indicated in the option;
It can not be proportional because the straight line through the points does not go through the originWhat is a proportional relationship?A proportional relationship is one in which one variable (the output variable) is a constant multiple of the input variable, such that a point on the graph of ordered pairs of variable is the point (0, 0), which is the origin.
The points on the graph are; (1, 3.5), (2, 4.5), (3, 5,5)
The slope of the graph is therefore; (4.5 - 3.5)/(2 - 1) = 1
The equation in point-slope form is therefore; y - 3.5 = x - 1
y = x - 1 + 3.5 = x + 2.5
y = x + 2.5
The equation is a linear relationship. The equation is in the form; y = m·x + c, with the slope m = 1 and a y-intercept, c = 2.5
The y-intercept is 2,5, therefore, the graph does not pass through the origin.
The relationship of the line passing through the points, is a linear relationship. The line passing through the points does not pass through the origin, therefore the relationship is not a proportional relationship
