Tyrese bought 35 tickets to use at a carnival. He used some of the tickets to ride the bumper cars and play some games. Now he has 28 tickets left. What is the percent of decrease in the number of tickets that he has?
The percent of decrease, in the number of tickets that he has, is 20%.
What is a percentage?The term "percentage" refers to any ratio or number that may be expressed as a fraction of 100. And the sign "%" is used to denote it.
Given, Tyrese bought 35 tickets to use at a carnival.
He used some of the tickets to ride the bumper cars and play some games. Now he has 28 tickets left.
That means,
he used 35 - 28 = 7 tickets.
To find the percentage of decrease:
Let m be the percentage of decrease.
Then,
7 = m x 35 / 100
m = 700 / 35
m = 20
Therefore, the percentage of decrease is 20%

what is the distance from the focus to the vertex of a parabola with the equation
x = 1/12 (y-1)²
help please!
Answer:
3 units.
Step-by-step explanation:
In the equation x = 1/12 (y-1)², the vertex of the parabola is at the point (1,1). The focus of the parabola is located a distance called the "focal length" from the vertex.
The focal length is given by the formula f = 1/(4*p), where p is the coefficient of the x term in the standard form of the equation of the parabola.
In this case, the coefficient of the x term is 1/12, so the focal length is f = 1/(4*(1/12)) = 3. This means that the distance from the focus to the vertex is 3 units.

What is the mean in math?
A dataset's mean (also known as the arithmetic mean, which differs from the geometric mean) is calculated by dividing the sum of all values by the total number of values. The term "average" is frequently used to describe this measure of central tendency.
What does the mode mean?
By summing all the numbers in a data collection and dividing by the total number of values in the set, the mean (average) of the data set can be determined.
A data collection is ordered from least to largest, and the median is the midpoint number. A data set's mode is the number that appears the most frequently.
What are the mean, median, and example?
The most frequent number, or the one that happens the most frequently, is known as the mode.
Example: Since the number 2 appears three times, more than any other number, it is the mode of the numbers 4, 2, 4, 3, and 2.

Solve for z [tex]2(5y+7x)^2=8\sqrt{3y-z[/tex]
The solution for z in the equation is z = 3y - 1/16(5y + 7x)⁴
How to determine the solution for z?From the question, we have the following parameters that can be used in our computation:
2(5y+7x)²=8√(3y-z)
Rewrite the equation
So, we have the following representation
2(5y + 7x)² = 8√(3y - z)
Take the square of both sides
This gives
4(5y + 7x)⁴ = 64(3y - z)
Divide both sides by 64
1/16(5y + 7x)⁴ = 3y - z
So, we have
z = 3y - 1/16(5y + 7x)⁴
Hence, the solution is z = 3y - 1/16(5y + 7x)⁴

A 20-foot ladder is leaning against the side of a house so that the bottom of the ladder is 12 feet from the base of the house. Will the ladder reach a window that is 14.5 feet above the ground?
Yes, because the 16 feet ladder will reach to the window that is 14.5 feet above the ground.
What is Pythagoras theorem?Pythagoras' Theorem states that the square of the hypotenuse side of a right-angled triangle equals the sum of the squares of the other two sides.
The hypotenuse of a triangle, which has a straight angle of 90 degrees, has a square that, according to the Pythagoras theorem, equals the sum of the squares of the other two sides.
According to the question;
A 20-foot ladder is leaning against the side of a house.
Hypotenuse H= 20 feet
The bottom of the ladder is 12 feet from the base of the house.
Base B = 12 feet
And let P be the perpendicular.
Using Pythagoras theorem
H²= P² + B²
20² =12² +P²
P²= 400-144
P²= 256
Taking the square root.
P= 16 feet.
Since the height of the ladder is 16 feet, and we have to reach 14.5 feet above the ground.
16 > 14.5
That means, the ladder will reach to the window.
Hence, Yes, the 16 feet ladder will reach to the window.

What is the relationship between the volumes of a rectangular prism and a rectangular pyramid whose length width and height are all equal?
The volume of the rectangular prism is 3 times the volume of the rectangular pyramid.
Consider a rectangular prism with length l, width w and height h.
The volume of the rectangular prism is:
volume of a rectangular prism = length * width * height
V1 = l * w * h
Consider a rectangular pyramid with rectangular base of length l1, width w1 and the height of pyramid is h1.
The volume of the rectangular pyramid is:
volume of a rectangular pyramid = 1/3 * base area * height
Here, base area = length * width
= l1 * w1
So, volume of a rectangular pyramid = 1/3 * base area * height
V2 = 1/3 * l1 * w1 * h1
We have been given a rectangular prism and a rectangular pyramid have equal length, width and height .
l1 = l, w1 = w and h1 = h

Is equidistant same as mid point?
Yes, since the midpoint of a line segment is at an equal distance from the two endpoints, it is said to be equidistant from them.
A point is said to be equally far from a group of objects if there is an equal distance between it and each member of the group.
The perpendicular bisector of two specified (different) points is their location in two-dimensional Euclidean geometry. The locus of points equidistant from two provided points in three dimensions is a plane, and generalizing further, the locus of points equidistant from two given locations in n-dimensional space is a (n1)-space.

The bunny had 1/2 to eat in the morning and 1/5 left over how much did the bunny eat at night
By applying the fraction concept, we can conclude that the bunny ate 3/10 food at night.
Application of the concept of fractions in real life
In real life, the concept of a fraction is often used when we want to talk about a part of a whole, a part of something, a part of a group of people, etc.
In the problem above it is stated that initially the bunny has food, which will be eaten in the morning and at night, and some food was left over.
If x is the total food for the bunny, then the given problem can be written mathematically as follows:
breakfast (a) : a = 1/2x
dinner (b)
food left (c) : c = 1/5x
Then the mathematical expression that describes the above situation is as follows:
x = a + b + c
= 1/2x + b + 1/5x --> then we make the denominators the same, so it becomes:
x = 5/10x + b + 2/10x
= 7/10x + b
x - 7/10x = b
3/10x = b
