The gallon is an imperial unit of measurement, which means that it is not used in most countries outside of the United States and the United Kingdom. In the US customary system, the gallon is divided into four quarts, each of which is equal to two pints. One US gallon is equivalent to approximately 0.83 imperial gallons, which are used in the UK.The gallon originated in medieval England as a measure for ale and other alcoholic beverages. It was adopted by the Romans during their invasion of Britain, and the term "gallon" is derived from the Latin term "galleta," which means "a pailful." The gallon was standardized in the 18th century by the British Imperial System.In the United States, the gallon is used in both the customary and imperial systems. In the customary system, the gallon is equal to 128 fluid ounces, while in the imperial system, it is equal to 160 fluid ounces. The US liquid gallon is divided into four quarts, which is equivalent to eight pints. One US dry gallon is equal to 4.4 liters.

if a data set is skewed to the left, how will the mean and median compare?
If a data set is skewed to the left, meaning that it has a long tail to the left (lower values), then the mean will be lower than the median. The median is less sensitive to outliers than mean.
In a data set that is skewed to the left, the mean will be less than the median. The term "skewed to the left" or "negative skewed" refers to the fact that the distribution of the data has a longer tail on the left side (towards smaller values) than on the right side.
When a data set is skewed to the left, it means that there are more lower values than higher values. As a result, the median (which is the middle value) will be larger than the mean (which is the average of all the values). The mean will be pulled down towards the lower values, making it smaller than the median.
For example, consider the following data set: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. The mean of this data set is 5.5, while the median is 5.5. However, if we add several low values to the data set, it will become skewed to the left: 1, 1, 2, 3, 3, 4, 5, 6, 7, 8, 9, 10.
The mean of this data set is now 4.5, while the median is still 5.5. The mean has moved towards the lower values, making it smaller than the median.

What is decimal value?A decimal value is a number expressed in the decimal system, which is based on the number ten. It includes a decimal point that separates the whole number part from the fractional part. The digits to the left of the decimal point represent whole numbers, and the digits to the right of the decimal point represent fractional parts of a whole number, which are expressed in powers of ten (tenths, hundredths, thousandths, etc.). For example, in the decimal value 3.14, the digit 3 represents the whole number part, and the digits 1 and 4 represent the tenths and hundredths parts, respectively. Decimal values are commonly used in mathematics, science, and everyday life to represent quantities that are not whole numbers, such as measurements, percentages, and money values.
Given by the question.
because the digit in the tenths place is larger in 2.8 than in 2.58. In decimal notation, the digit immediately to the right of the decimal point represents tenths, and larger values in this place indicate a larger overall value.

The roots of the polynomial are the height, length, and width of a rectangular box (right rectangular prism). A new rectangular box is formed by lengthening each edge of the original box by 2 units. The volume of the new box is ________.
The volume of the new box is 30 units³.
We can infer the roots are rational integers from the response options, thus this polynomial ought to be simple to factor. The coefficients of x must multiply by 10, hence they must be in some sequence of 5, 2, 1 or 10, 1. Since we can try each one separately, we can express the factored form as follows:
(5x-p)(2x-q)(x-r)
Due to the fact that p, q, and r must multiply to 6, they must be either 3, 2, 1 or 6, 1, 1 in some sequence. Once more, we may test each one in a different place to determine if they multiply properly.
When we multiply the x-terms and attempt (5x - 2)(2x - 1)(x - 3), the answer is 29. Try adding the x² terms together, they equal -39. Consequently, the roots are 2/5, 1/2 and 3 Now if you add 2 to each root, you get the volume is
= 12/5 × 5/2 × 5 = 30 units³
Therefore, The volume of the new box is 30 units³.

2x^+4=8^x
Answer:
the solution to the equation 2x^+4=8^x is x = 1.
Step-by-step explanation:
To solve the equation 2x^+4=8^x, we can start by simplifying both sides of the equation.
First, we can rewrite 8^x as (2^3)^x, using the property that 8 is equal to 2 raised to the power of 3.
So, the equation becomes:
2x^+4 = (2^3)^x
2x^+4 = 2^(3x)
Next, we can rewrite 2x^+4 as 2^2 * 2^x, using the property that a^b * a^c = a^(b+c).
So, the equation becomes:
2^2 * 2^x = 2^(3x)
2^(x+2) = 2^(3x)
Now, we can equate the exponents on both sides of the equation:
x + 2 = 3x
2x = 2
x = 1
Therefore, the solution to the equation 2x^+4=8^x is x = 1.

Given expression:x² + 7x - 18
Using mid-term break formula.
Multiply the side terms. [-18 × x² = -18x²]Now, split the mid-term in such two factor, such that multiplying both gives the side terms.We can split -7x (mid term) into -9x + 2x since -9x × 2x = -18x²So,
= x² - 9x + 2x - 18
Now, take x from (x² - 9x) and 2 from (2x - 18) common

Starting amount
Show your reasoning.
b. Explain why we can find the area covered by algae 1 day after it was spotted by
multiplying 12.5 by V2.
Answer:
Step-by-step explanation:
a) The area covered by algae 10 days after it was first spotted is approximately 32.64 square meters.
b) We can find the area covered by algae one day after it was first spotted by multiplying [tex]12.5^{1/7}[/tex] by 2.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
a.
To find the area covered by algae 10 days after it was first spotted, we need to convert 10 days into weeks, since the growth rate is given in terms of weekly doubling.
There are 7 days in a week,
So 10 days are approximately 1.43 weeks (10/7).
Let A be the area covered by algae in square meters after n weeks.
Then we can use the formula for exponential growth:
A = 12.5 x [tex]2^n[/tex]
Substituting n = 1.43, we get:
A = 12.5 x [tex]26^{1.43}[/tex]
A ≈ 32.64
Therefore,
The area covered by algae 10 days after it was first spotted is approximately 32.64 square meters.
b.
We know that the area covered by algae doubles each week.
One week is equivalent to 7 days, so after one week, the area covered by algae will be twice the initial area of 12.5 square meters, or 25 square meters.
We can represent this mathematically as:
A = 12.5 x [tex]2^1[/tex]
Now, let's consider what happens after two weeks, or 14 days.
The area covered by algae will double again, so it will be four times the initial area of 12.5 square meters or 50 square meters.
We can represent this mathematically as:
A = 12.5 x 2²
Using the same reasoning, we can find that after three weeks (21 days), the area covered by algae will be eight times the initial area or 100 square meters:
A = 12.5 * 2³
In general, we can see that after n weeks, the area covered by algae will be 2^n times the initial area of 12.5 square meters. This can be written as:
A = 12.5 x [tex]2^n[/tex]
If we want to find the area covered by algae after one day, we can use the fact that one day is equivalent to 1/7 of a week.
So, after one day, the area covered by algae will be:
A = 12.5 x [tex]2^{1/7}[/tex]
Simplifying this expression using the laws of exponents, we get:
A = [tex]12.5^{1/7}\times2[/tex]
Therefore,
We can find the area covered by algae one day after it was first spotted by multiplying [tex]12.5^{1/7}[/tex] by 2.

A triangle is a two-dimensional shape with three straight sides and three angles. It is one of the most basic and important shapes in geometry.
The three sides of a triangle can be of different lengths, or they can be of the same length, in which case it is called an equilateral triangle. The angles of a triangle can also vary, and they always add up to 180 degrees. Triangles can have acute angles (less than 90 degrees), right angles (exactly 90 degrees), or obtuse angles (greater than 90 degrees).
According to given information :
Ratio of short to long sides:
x/9 = 9/4
To solve for x, we can cross-multiply:
4x = 9 * 9
4x = 81
x = 81/4
So the ratio of the short side to the long side is:
x/9 = (81/4) / 9 = 81/36 = 9/4
Ratio of hypotenuse to long sides:
y/9 = 15/12
To solve for y, we can cross-multiply:
12y = 9 * 15
12y = 135
y = 135/12 = 45/4
So the ratio of the hypotenuse to the long side is:
y/9 = (45/4) / 9 = 45/36 = 5/4
Therefore, the ratio of the short side to the long side is 9/4 and the ratio of the hypotenuse to the long side is 5/4.

Prove by contradiction in a right triangle with integer sides, the two shorter sides cannot both be odd
Prove by contradiction that in a right triangle with integer sides, the two shorter sides cannot both be odd.
Assume that the two shorter sides, a and b, of a right triangle are both odd integers. Then the hypotenuse, c, must also be an integer. From the Pythagorean theorem, we know that c2 = a2 + b2. We can rewrite this as c2 = (2m + 1)2 + (2n + 1)2, where m and n are integers. We can expand the left-hand side of the equation to get c2 = 4m2 + 4n2 + 4m + 4n + 1. Since c2 is an even integer, 4m2 + 4n2 must be an even integer as well. But, since 4m + 4n + 1 is odd, the only way to make the left-hand side of the equation an even integer is if 4m2 + 4n2 is an odd integer, which is impossible.
Therefore, our initial assumption that a and b are both odd integers is false. Thus, in a right triangle with integer sides, the two shorter sides cannot both be odd.

where we have
[tex]\rm when \: x=x_1, y = y_1\\when\: x = x_2, y= y_2[/tex]
Remember that, we divide by the change in independent variable so that we get some idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.
(5 change per 3 unit can be rewritten as 5/3 change per 1 unit)
We are given that;
Cost of coat=$38
Rate= 4.5%
Now,
To find out how much Ali paid in sales tax, we need to multiply the purchase price by the sales tax rate:
Sales tax amount = Purchase price x Sales tax rate
Sales tax rate = 4.5% = 0.045 (in decimal form)
