It doesn't run on straight gasoline, you have to mix the oil and gas together in a specific ratio of 2.4 fl. oz. of oil for every gallon of gasoline. You have 1.5 quarts of gas. How much oil should you add?
You should add 115.2 fluid ounces of oil to your 1.5 quarts of gasoline.
What is an expression?An expression is a group of symbols and/or numbers used to represent a quantity or a mathematical relationship between two quantities in mathematics. Variables, constants, as well as operators like addition, subtraction, multiplication, and division, can all be found in an expression.
Since there are 4 quarts in a gallon, 1.5 quarts is equal to 1.5/4 = 0.375 gallons of gasoline.
To determine how much oil to add, we need to use the ratio of 2.4 fl. oz. of oil for every gallon of gasoline.
First, we need to convert the amount of gasoline we have from gallons to fluid ounces:
0.375 gallons x 128 fluid ounces per gallon = 48 fluid ounces of gasoline.
Next, we can use the ratio to find how much oil to add:
2.4 fl. oz. oil: 1 gallon gasoline
x fl. oz. oil: 48 fl. oz. gasoline
Cross-multiplying, we get:
2.4 x 48 = 1 x (x)
115.2 = x
So you should add 115.2 fluid ounces of oil to your 1.5 quarts of gasoline.

Which form most quickly reveals the zeros (or "roots") of the function?
All forms are equal.
1.[tex]f(x) = -3x^2+12x+15[/tex]
2.[tex]-3(x+1)(x-5)[/tex]
3. [tex]-3(x-2)^2+27[/tex]
What are the zeros?
By answering the above question, we may infer that Hence, x = -1 and x = equation 5 are the zeros of the function f(x).
What is equation?A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The logo and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.
To apply this technique, the quadratic function must be rewritten in vertex form as follows: f(x) = a(x-h)2 + k, where (h,k) is the vertex of the parabola.
The coefficient -3 from the first two terms is first removed by factoring: [tex]f(x) = -3(x^2 - 4x) + 15.[/tex]
After that, we finish the square enclosed in parenthesis by calculating (4/2)2 = 4:
[tex]F(x) = -3[(x-2)2 - 4] + 15 F(x) = -3(x-2)2 + 27 F(x) = -3[(x-2)2 - 4] + 15[/tex]
The parabola is at (2, 27), and because the squared term's coefficient is negative, the parabola widens downward. Set f(x) = 0 and solve for x to discover the zeros: [tex]0 = -3(x-2)2 + 27 3(x-2)2 = 27 (x-2)2 = 9 x-2 = 9 x = 2 3[/tex]
Hence, x = -1 and x = 5 are the zeros of the function f(x).

Find the number of arrangements that can be made by taking 4 letters from the letters of the word addressee.
Answer: The word "addressee" has 8 letters. To find the number of arrangements that can be made by taking 4 letters from these 8 letters, we can use the formula for combinations, which is:
n C r = n! / (r! * (n-r)!)
where n is the total number of items, r is the number of items to be selected, and ! represents the factorial function.
In this case, we want to select 4 letters from the 8 letters in "addressee", so n = 8 and r = 4. Substituting these values into the formula, we get:
8 C 4 = 8! / (4! * (8-4)!)
= (8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / [(4 * 3 * 2 * 1) * (4 * 3 * 2 * 1)]
= 70
Therefore, there are 70 different arrangements that can be made by taking 4 letters from the letters of the word "addressee".

Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of
cubic feet, HCF). When graphed, the function gives a line with a slope of 1.65. See the figure below.

The monthly cost for an HCF of 24 will be $39.13.
What is an expression?In mathematics, an expression is a combination of symbols and/or numbers that represents a quantity or a mathematical relationship between quantities. An expression can consist of variables, constants, and operators such as addition, subtraction, multiplication, and division.
Since the monthly water bill is a linear function of the amount of water used, we can use the point-slope form of a linear equation to write an equation for the line. Let y be the monthly cost (in dollars) and x be the amount of water used (in HCF). Then the equation of the line is:
y - 49.58 = 1.65(x - 21)
Simplifying this equation, we get:
y = 1.65x - 13.57
This means that the monthly cost (y) is equal to 1.65 times the amount of water used (x) minus a constant term of $13.57.
To find the monthly cost for 24 HCF, we simply substitute x = 24 into the equation we just found:
y = 1.65(24) - 13.57
y = 39.13
Therefore, the monthly cost for 24 HCF is $39.13.

Suppose you have 3 jars with the following contents. Jar 1 has 1 white ball and 1 black ball. Jar 2 has 2 white balls and 1 black ball. Jar 3 has 1 white ball and 1 black ball. One jar is to be selected, and then 1 ball is to be drawn from the selected jar. The probabilities of selecting the first, second, and third jars are 1/2, 1/3, and 1/6 respectively. Find the probability the ball was drawn from Jar 3, given that the ball is white.
Given that the ball is white, the probability that it was taken from Jar 3 is 1/5, or 0.2. Given that the ball is white, there is a 20% likelihood that it was selected from Jar 3.
How is probability determined?We must apply Bayes' theorem in order to determine the likelihood that the ball was taken from Jar 3 given that it is white. Let J stand for the scenario in which Jar 3 is chosen, and W for the scenario in which a white ball is drawn. Next, we have:
P(W | J) * P(J) / P = P(J | W) (W)
where P(J) is the prior probability of choosing Jar 3 (1/6), P(W) is the probability of drawing a white ball, and P(W | J) is the probability of drawing a white ball provided that Jar 3 is chosen.
We must apply the law of total probability to determine P(W):
P(W) is equal to P(W | J1) * P(J1), P(W | J2) * P(J2), and P(W | J3) * P. (J3)
where P(W | J1) represents the likelihood that a white ball will be drawn if Jar 1 is chosen (which is 1/2), P(W | J2) represents the likelihood that a white ball will be drawn if Jar 2 is chosen (which is 2/3), and P(W | J3) represents the likelihood that a white ball will be drawn if Jar 3 is chosen (which is 1/2).
Now that the values have been inputted, we can calculate:
P(W) = (1/2 * 1/2) + (2/3 * 1/3) + (1/2 * 1/6) = 5/12
P(J | W) = (1/2 * 1/6) / (5/12) = 1/5

Step-by-step explanation:
Which of the following sets of numbers could represent the three sides of a right triangle? O {9, 24, 26} O {37, 77,85} O {65, 72, 97} O {32, 56, 65}
From the given data, the only set of numbers that could represent the sides of a right triangle is {9, 24, 26}.
The set of numbers that could represent the three sides of a right triangle is {9, 24, 26}.
To determine if a set of numbers could represent the sides of a right triangle, we can use the Pythagorean theorem, which states that for a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. That is,
c² = a² + b²
where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.
For the set {9, 24, 26}, we have:
26² = 9² + 24²
676 = 81 + 576
Therefore, the set {9, 24, 26} could represent the three sides of a right triangle.
For the other sets:
{37, 77, 85}: 85² ≠ 37² + 77², so this set does not represent the sides of a right triangle.
{65, 72, 97}: 97² ≠ 65² + 72², so this set does not represent the sides of a right triangle.
{32, 56, 65}: 65² ≠ 32² + 56², so this set does not represent the sides of a right triangle.

Salma and her children went into a bakery and will buy cupcakes and brownies. She must buy no less than 15 cupcakes and brownies altogether.
Write an inequality that would represent the possible values for the number of cupcakes purchased, c, and the number of brownies purchased, b.
The inequality that represents possible values for the number of cupcakes purchased, c, and the number of brownies purchased, b is:
(c+b) ≥ 15
What is meant by inequality?In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal. However several inequalities are utilised to compare the numbers, whether it is less than or higher than. An inequality symbol has non-equal expressions on both sides. It indicates that the expression on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using inequality symbols.
It is given that the least number of cupcakes and brownies that Salma should buy is 15.
Let the number of cupcakes purchased be c and the number of brownies purchased, b.
Then the total number of cupcakes and brownies is c + b
This sum should be greater than or equal to 15.
Then the inequality is (c+b) ≥ 15
Therefore the inequality that represents possible values for the number of cupcakes purchased, c, and the number of brownies purchased, b is:
(c+b) ≥ 15

O is the center of the regular octagon below. Find its area. Round to the nearest tenth if necessary.
The answer of the given question based on regular octagon ,the area of the regular octagon with center O is approximately 232.98 square units.
What is Area?Area is measure of amount of space inside 2-dimensional figure or shape, usually measured in square units like square centimeters or square meters. It is calculated by multiplying length and width of the figure or a shape.
To find the area of a regular octagon, we need to use the following formula:
A = 2(1 + √2) × s²
Since O is the center of the octagon, we can draw lines from O to each vertex of the octagon. This will divide the octagon into 8 congruent isosceles triangles.
Let's call the length of each side of the octagon "s". Then the base of each triangle will also be "s". We can use the Pythagorean theorem to find the length of the other sides of the triangle:
s²+ s² = (2s)²/2
2s² = 4s² - 4s²/2
2s² = 2s²/2
s² = s²/2
s = √2s/2
Now we can substitute this value of s into the formula for the area of the octagon:
A = 2(1 + √2) × s²
A = 2(1 + √2) × (√2s/2)²
A = 2(1 + √2) × 2s²/4
A = (1 + √2) × s²/2
A = (1 + √2) × (17/2)²/2
A ≈ 232.98 square units
Therefore, the area of the regular octagon with centre O is approximately 232.98 square units.

Answer:
Step-by-step explanation:
Let's call the number of lessons attended "x".
Option A: Total cost = $260 + $10x
Option B: Total cost = $30x
We want to find when the two options have the same cost:
$260 + $10x = $30x
Subtracting $10x from both sides:
$260 = $20x
Dividing both sides by $20:
x = 13
Therefore, after attending 13 lessons, the total cost for both options will be the same.
