Which number gives the same result if it is multiplied by 999/998 or if any number is added to it?
Please give me the answer with an explanation!
Thanks in advance!
Answer:
The number that gives the same result if it is multiplied by 999/998 or if any number is added to it is zero (0).
The property of a number being unchanged after being multiplied by a fraction and a constant is called an "Identity element". The identity element for multiplication is 1 and for addition is 0.
When any number is multiplied by 1, it stays the same. So, if we multiply any number by 999/998, which is equivalent to multiplying by 1, it stays the same.
Similarly, when any number is added to zero, it stays the same. So, if we add any number to 0, it stays the same.
Therefore, the only number that gives the same result if it is multiplied by 999/998 or if any number is added to it is zero (0).
several different types of cheese are produced in the shape of a wheel. because of the differences in consistency of these different types of cheese, there is variation in the amount of cheese in the wheel. cam embert wishes to determine if there is a significant difference, at the 5% level, between gouda cheese and brie cheese. she randomly samples 18 wheels of gouda and finds the mean is 1.3 pounds with a standard deviation of 0.31 pound and 13 wheels of brie and finds a mean of 0.95 pounds and a standard deviation of 0.26 pound. is the difference between the weights of the two cheeses significant at the 0.05 level of significa
There is a statistically significant difference between the weights of the two cheeses at the 5% level of significance.
What is standard deviations?Standard deviation is a measure of how spread out a set of numbers is from the mean. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean. In other words, it is a measure of how much the values in a dataset differ from the mean, or average, value. Standard deviation is a useful tool for understanding the distribution of data and can be used to identify outliers and compare data sets.
To answer this question, we must use a two-tailed hypothesis test, where the null hypothesis is that there is no difference between the two cheeses. The alternative hypothesis is that there is a significant difference between the two cheeses.
Using the sample data provided, we are able to calculate the test statistic, which in this case is 2.02. This can be compared to the critical value from the t-distribution table, which is 1.711 for a 5% level of significance and 31 degrees of freedom.
Since the test statistic is larger than the critical value, we reject the null hypothesis and conclude that there is a statistically significant difference between the weights of the two cheeses at the 5% level of significance.

An ant crawling along the floor follows a semi-circular path, going halfway around the circumference of a circle of radius R.
The distance traveled and the displacement of the ant are, respectively,
πR and πR
2R and πR
πR and 2R
πR and zero
none of these
The ant's entire distance travelled along its semicircular journey is its total distance travelled overall. The ant is travelling around a circle with radius R, thus the distance it has travelled is equal to half of the circle's circumference, πR.
The change in the ant's position is represented by a vector quantity called the displacement of the ant. The ant in this scenario begins at one end of the semi-circular path and moves 2R away from the beginning point to reach the other end. The direction of the displacement vector is from the starting point to the ending point, and the displacement's magnitude is equal to the 2R distance between the two points.
So, the option c is most suitable option.
Therefore, πR and 2R are the ant's displacement and the distance travelled, respectively.

does it make sense that the number of cats falling frm the 5th floor would be greater than those of the 4th
Yes, it makes sense that the number of cats falling from 5th floor would be greater since the terminal velocity of the cat would be greater at higher altitudes.
What is velocity?The pace at which an object's location changes in relation to a frame of reference and time is what is meant by velocity. Although it may appear sophisticated, velocity is just the act of moving quickly in one direction. Since it is a vector quantity, the definition of velocity requires both magnitude (speed) and direction.
What is altitude?A distance measurement between a reference datum and a point or object, typically in the vertical or "up" direction, is known as altitude, height, or depth.
The terminal velocity of the cat would be greater at higher altitudes; hence cats have higher risk of falling from heights.

The area of the shaded portion of the figure is 272 units squared.
How to find area of a figure?The figure above is a triangle inside a trapezium. The area of the shaded portion can be found when we subtract the area of the triangle from the area of the trapezium.
Therefore,
area of the shaded portion = area of the trapezium - area of the triangle
area of the triangle = 1 / 2 bh
where
b = baseh = heightTherefore,
area of the triangle = 1 / 2 × 18 × 16
area of the triangle = 288 / 2
area of the triangle = 144 units²
area of the trapezium = 1 / 2 (a + b)h
where
a and b are the top and baseh = height of the trapeziumTherefore,
area of the trapezium = 1 / 2 (18 + 34)16
area of the trapezium = 1 / 2 (52)16

A large cheese pizza at a palanzios pizzeria costs $6.80 plus $0.90 for each topping. the cost of a large cheese pizza at gordos pizza is $7.30 plus $0.65 for each topping. how many toppings need to be added in the order for the pizzas to cost the same.
For Palanzios' Pizzeria and Guido’s Pizza to cost the same, the number of toppings needed is 2.
Let's begin by assigning a letter to represent our unknown:
x = Number of toppings to be added to each pizza
Now,
Based on the Given information :
Expressions for the cost of each pizza with its toppings:
Palanxio's Pizza: 6.80 + 0.90x
Guido's Pizza: 7.30 + 0.65x
Now,
Equating the costs of both pizzas and solve for our unknown (x):
⇒ 6.80 + 0.90x = 7.30 + 0.65x
⇒ 0.90x - 0.65x = 7.30 - 6.80
⇒ 0.25x = 0.50
⇒ x = 0.50/0.25
⇒ x = 2
Therefore, There are 02 toppings to be added to each pizza.
Finally, we can verify our answer by putting the values back into our equation :
6.80 + 0.90x = 7.30 + 0.65x
6.80 + 0.90(2) = 7.30 + 0.65(2)
6.80 + 1.80 = 7.30 + 1.30

The central angle of the arc in degrees is 162 degrees.
How to find the central angle ?The circumference of the circle is 10 units. The length of the arc is 9 / 2 units. The central angle can be calculated as follows;
We can find the central angle by comparing it to the length of the arc.
Therefore, we know the circle has a circumference of 10. We also know a circle is 360°. The length of the arc is given as 9 / 2 units(4.5 units).
To determine the degrees of the central angle, we have to set up a ratio and set the unknown angle as x.
Hence,
length of the arc / circumference = angle of the arc / angle of the circle
4.5 / 10 = x / 360
cross multiply
360 × 4.5 = 10x
1620 = 10x

a cylindrical water tank with its circular base parallel to the ground is being filled at the rate of 4 cubic feet per minute. the radius of the tank is 2 feet. how fast is the level of the water in the tank rising when the tank is half full?
Answer:
To solve this problem, we need to use the formula for the volume of a cylinder: V = πr^2h, where V is the volume, r is the radius, and h is the height.
Step 1: We know that the radius of the tank is 2 feet and that it is being filled at a rate of 4 cubic feet per minute. We also know that the tank is half full, so we can assume that the height of the water in the tank is half the height of the tank itself.
Step 2: We can use the volume formula to find the volume of the tank when it is half full.
V = πr^2h
V = π(2^2)(h/2)
V = 4πh/2
Step 3: We can divide the rate of fill by the volume of the tank when it is half full to find the rate of change of the height of the water.
dh/dt = 4/(4π/2)
dh/dt = 2/π ft/min
Final Answer: The level of the water in the tank is rising at a rate of 2/π feet per minute when the tank is half full.
The number of inches in the perimeter of an equilateral triangle equals the number of square inches in the area of its circumscribed circle. What is the radius, in inches, of the circle?
(A) 32√π32π
(B) 33√π33π
(C) 3√3
(D) 6π6π
(E) 3√∗π
The radius of the circle is s√3π, which is equal to 3√π. Hence, the answer is option (B).
To calculate the radius of the circle, we need to first calculate the perimeter of the equilateral triangle. The perimeter of an equilateral triangle is equal to 3 times the side length of the triangle. Thus, we can say that the perimeter of the equilateral triangle is 3s.
Now, we need to calculate the area of the circumscribed circle. The area of a circle is equal to π times the square of the radius. Thus, the area of the circumscribed circle is equal to πr2.
