The percentage is the indicating hundredth of any change in quantity thus the percentage increase of cars from $2800 to $4500 is 60.72%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
As per the given question,
Buying cost of car = $2800
Selling cost of car = $4500
Percentage change = (change/original) × 100
Percentage change = [(4500 - 2800)/(2800)] × 100
Percentage change = [(1700)/2800] × 100
Percentage change = 0.607 × 100
⇒ 60.72%
Hence "The percentage is the indicating hundredth of any change in quantity thus the percentage increase of cars from $2800 to $4500 is 60.72%".

The quotient of -18 and the sum of -2 and d
The quotient of -18 and the sum of -2 and d can be represented mathematically as -18 ÷ (d - 2), where we subtract 2 from d and then divide -18 by that result.
Explanation:The quotient of -18 and the sum of -2 and d refers to dividing -18 by the result of adding -2 to d (which we can represent as d - 2 because adding a negative number is equivalent to subtracting). Mathematically, we can express this as -18 ÷ (d - 2).
To perform this operation, we first need to know the value of d. Once we have that, we subtract 2 from it, and then divide -18 by that result.
For example, if d was 4, we would perform the operation as follows: 4 - 2 gives us 2, then -18 ÷ 2 gives us -9. So, the quotient of -18 and the sum of -2 and 4 (d being 4) is -9.

What is Hypotenuse?A hypotenuse is defined as the longest side of a right triangle, the side opposite the right angle where the length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of is the square of the lengths of the other two sides.
The equation is expressed as:
[tex]a^2 + b^2 = c^2[/tex]
a = side of right triangle
b = side of right triangle
c = hypotenuse
For above given information, the problem describes a right triangle with hypotenuse 12, the side against the ground is 4, and the angle between those two sides is "x".
For this triangle,
cosx = (side adjacent to angle) / hypotenuse
= 4 /12= 1/3
x is approximately 70.52° which is 71° rounded to the nearest degree.
Thus, x = 71 degrees. Yes, the ladder meets safety standards.

How can you tell when there are 1001 pickles under the bed worksheet?
To find the probability of getting a blue jelly bean, we use the equation P = B / Total. Substituting the given values, we find that the probability of getting a blue jelly bean is approximately 0.1733 or 17.33%.
Explanation:To solve the given problem, we can use the equation provided in the example: P = B / 26. Since we know that there are 26 blue jelly beans out of 150 total jelly beans, we can substitute these values into the equation to find the probability: P(B) = 26 / 150. Simplifying this fraction, we get P(B) = 13 / 75.
Therefore, the probability of getting a blue jelly bean is 13/75, or approximately 0.1733, which can be expressed as a percentage as 17.33%.

Which of the following is true of an outlier?
An outlier is a false data point.
An outlier does not affect measures of central tendency.
An outlier is not near the main cluster of data.
An outlier is always the highest or lowest value in a data set.
An outlier is a data point that is significantly different from the other data points in a set. It may or may not affect measures of central tendency. Outliers are not always the highest or lowest values in a data set.
Explanation:An outlier is a data point that is significantly different from the other data points in a set. It can be either higher or lower than the other values.
Outliers may be errors or abnormal data, or they may provide valuable insights into the population under study.
An outlier does not necessarily mean that it is a false data point. It needs to be examined closely to determine if it should be included in the analysis or not.
An outlier may or may not affect measures of central tendency, such as the mean, median, and mode.
It depends on the specific data set and the impact of the outlier on these measures. It is not always the highest or lowest value in a data set, as it can be any data point that deviates significantly from the rest.

Find the equation of the circle in standard form for the given center (h,k) and radius r: (h,k)=(0,0), r=9
Answer: [tex]x^2+y^2=81[/tex]
Step-by-step explanation:
The equation of circle ( in general form ) is given by :_
[tex](x-h)^2+(y-k)^2=r^2[/tex]
, where r= radius of the circle .
(h,k) = center of the circle .
Given : Center = (h,k)= (0,0)
Radius = r = 9 units
Then the equation of the circle will be :-
[tex](x-0)^2+(y-0)^2=(9)^2[/tex]
[tex]\Rightarrow x^2+y^2=81[/tex]
Hence, the required equation of the circle = [tex]x^2+y^2=81[/tex]

A spherical tank has a capacity of 400 gallons. using the fact that 1 gallon is about 0.1337 ft3, find the radius of the tank (to the nearest hundredth of a foot).
Final answer:
To find the radius of a spherical tank with a capacity of 400 gallons, calculate the volume and use the formula for the volume of a sphere.
Explanation:
A spherical tank has a capacity of 400 gallons, which is approximately 533.47 ft³ (400 gallons x 0.1337 ft³/gallon).
To find the radius, use the formula for the volume of a sphere: V = (4/3)πr³. Set this equal to the volume and solve for the radius.
Substitute the volume (533.47 ft³) into the formula, solve for r, and you will find that the radius is approximately 4.88 feet.

Find an equation of the vertical line that passes through (x, y) = (14, 15).
Final answer:
The equation of the vertical line passing through the point (14, 15) is x = 14.
Explanation:
To find an equation of a vertical line that passes through the point (14, 15), we need to understand that a vertical line has an undefined slope and therefore cannot be represented by the slope-intercept form of a line, y = mx + b. Instead, vertical lines are represented by equations where x is equal to a constant value since every point on the vertical line will share the same x-coordinate. Thus, the equation of the vertical line passing through (x, y) = (14, 15) is simply x = 14.

Step-by-step explanation:
7 percent of the number 20.00 is 1.4.
What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Given that, 7% of 20.00
A percentage is a number or ratio that can be expressed as a fraction of 100.
Let x be the 7% of 20.00.
Here, 7% of 20.00 =x
7/100 ×20.00 =x (word "of" means multiplication)
0.07×20.00 =x
x=1.4
Therefore, 7 percent of the number 20.00 is 1.4.

Y=x3, vertically stretch by a factor of 4. How would the final equation look like?
Vertically stretching the equation[tex]Y=x^3[/tex] by a factor of 4 results in the equation [tex]Y=4x^3[/tex]. This means that the value of the function increases four times for every x. Visually, the stretched function appears steeper along the y-axis.
Explanation:The equation represents[tex]Y=x^3[/tex] a cubic function. When you vertically stretch a function by a factor of 4, this means you multiply the output (Y-values) of the function by 4. Therefore, to vertically stretch Y=x3 by a factor of 4, you will multiply the entire function by 4. The final equation would look like [tex]Y=4x^3[/tex]
To clarify, the 'stretch' implies that for each x, the value of the function increases four times. This change can is noticeable graphically as the function will look 'steeper' or 'more stretched out' along the y-axis.
