Mr. Ellis has a bakery and sells cookies. This week, he made 4 dozen chocolate chip cookies, 3 dozen oatmeal raisin cookies, and 5 dozen sugar cookies. He sold 135 cookies. How many cookies does Mr. Ellis have left? (One dozen = 12.)

The least amount of water required to measure exactly 2 oz is 12 oz. (13 oz + 7 oz - 8 oz = 12 oz).

First, add 13 oz of water to the 20 oz bottle. The combined amount of water will now be 33 oz.

Next, pour water from the 33 oz bottle into the 13 oz bottle until the 13 oz bottle is full to the top.

The remaining amount of water in the 33 oz bottle will be 20 oz.

Now, pour out the water in the 13 oz bottle into the 20 oz bottle.

Now, the 20 oz bottle will have 13 oz of water in it. This leaves the 33 oz bottle with 7 oz of water remaining in it.

Now, pour the remaining 7 oz of water in the 33 oz bottle into the 20 oz bottle.

The 20 oz bottle will now have 20 oz + 7 oz = 27 oz of water in it.

Pour out the water in the 20 oz bottle until the amount of water in it is exactly 2 oz.

Since you started with a combined amount of 33 oz, and the amount of water remaining in the 20 oz bottle is 2 oz, the

amount of water poured out is 33 oz - 2 oz = 31 oz.

Therefore, the least amount of water required to measure exactly 2 oz is 12 oz.

After solving the linear equation Lillian is farther along in the book than Khadija after 4 days.

A linear equation is an algebraic equation of the form:

y = mx + b

where x and y are variables, m is the slope of the line, and b is the y-intercept. The slope represents how steep the line is, and the y-intercept is the point at which the line intersects the y-axis.

As we know, Lillian was on 40 pages and Khadija was on 10 pages. So, the equation is,

And Let L represent the page of the book that Lillian is on at the end of t days into the month, and let K represent the page of the book that Khadija is on at the end of t days into the month.

[tex]L(t) = 40 + 15t[/tex]   Lillian's progress after t days

[tex]K(t) = 10 + 20t[/tex]  Khadija's progress after t days

After solving the linear equation, we will get the rate of the reading page.

Let's say t=4,

[tex]L(4) = 40 + 15(4) = 100[/tex]

[tex]K(4) = 10 + 20(4) = 90[/tex]

Thus, the following is the rule for the given geometric sequence: [tex]a = 64 * (-2)^(n-1) (n-1)[/tex]. Thus, the solution is (C) a = 64(-2)n-1.

An structured of integers or objects that adhere to a particular pattern or rule is referred to as a sequence in mathematics. The name for each number or item in the sequence is. A series can be explicitly created or defined recursively, and it can be infinite or finite. A method or rule that directly expresses the n - th term of the series in terms of n defines an explicit sequence. For instance, the explicit sequence 2, 4, 6, 8, 10,... has the formula a = 2n, where n is the term's position inside the sequence. A starting value and recursive formula that determines the nth word of the series in terms of the preceding terms describe a recursive sequence.

given

The number sequence is as follows: 64, -128, 256, -512.

We must determine the common ratio between the following terms in order to get the rule for this sequence.

Any term can be divided by its previous term to obtain the common ratio (r). For instance, the result of subtracting the second term (-128) from the first term (64) is

r = (-128) / 64 = -2

The third term (256) divided by the second term (-128) results in:

r = 256 / (-128) = -2

And when the fourth term (-512) is divided by the third term (256), the result is

r = (-512) / 256 = -2

We can observe that for all pairings of following terms, the common ratio is -2.

Now we can apply the following formula to a geometric sequence's general term:

a = a1 * r^(n-1) (n-1)

where r is the common ratio and a1 is the first term.

In place of the values we hold:

[tex]a = 64 * (-2)^(n-1) (n-1)[/tex]

Thus, the following is the rule for the given geometric sequence: [tex]a = 64 * (-2)^(n-1) (n-1)[/tex]. Thus, the solution is (C) a = 64(-2)n-1.

Answer:

72 degrees

Step-by-step explanation:

The given points can only be represented by an exponential function.

A linear function has the following form = y = f(x) = a bx

A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

a is a constant term or y-intercept. This is the value of the dependent variable when x = 0.

b is the coefficient of the independent variable. It is also called the slope and gives the rate of change of the dependent variable.

 We can determine the type of function that can represent the given points by looking at the pattern of y values ​​corresponding to the x values.

Linear Function: A linear function has a constant slope, which means that the difference between any two consecutive values ​​of y must be the same as the difference between  two consecutive values ​​of x. The difference between  two consecutive y values ​​is 9/8, which is not the same as the difference between  two consecutive x values ​​(which is 1). Therefore, the given points cannot be represented by a linear function.  Exponential function: an exponential function has a constant ratio between  two consecutive y-values, meaning that the ratio of any two consecutive y-values ​​must be the same as the ratio of any two consecutive x-values.

The ratio of  two consecutive y values ​​is 2, which is the same as the ratio of  two consecutive x values ​​(which is 1/2). Therefore, the given scores can be represented by an exponential function.  Quadratic function: A quadratic function has a quadratic term, which means that the y-values ​​should show an increasing or decreasing pattern of differences between successive x-values.  The differences between successive y values ​​are 9/8, 3/8, 1/2, and 9. There is no  pattern of increasing or decreasing differences between successive x values, so the given points cannot be represented by a square. function

Step-by-step explanation:

To find the diameter of the Andromeda galaxy in miles, we can use the given information:

Diameter of Andromeda galaxy = 2.2 X 10^5 light-years

1 light-year = 5.9 X 10^12 miles

So, we can use dimensional analysis to convert light-years to miles:

2.2 X 10^5 light-years * 5.9 X 10^12 miles/light-year = 1.298 X 10^18 miles

Therefore, the diameter of the Andromeda galaxy in miles is approximately 1.298 X 10^18 miles.

Answer:

Yes, the triangle with sides 8, 15, and 17 is a Pythagorean triple. This is because 8^2 + 15^2 = 64 + 225 = 289 = 17^2. As for the acute angle between sides 8 and 15, we can use the inverse tangent function to find it. tan(theta) = 8/15 theta = arctan(8/15) Using a calculator, we find that theta ≈ 28.07 degrees. Since we know this is an acute angle, we can conclude that it measures between 0 and 90 degrees, and is closer to 28 degrees than to 62 degrees.

Answer:

a. Similar

Step-by-step explanation:

The question says the triangles are right triangles, so they can't be obtuse or equilateral.

Since they are both right triangles, they both have a 90° angle. And as stated in the question, they both have a 30° angle. By Angle-Angle (AA) they are similar. But we don't know anything about any sides in either triangle, so we don't know if they are congruent or not. Just we can only know they are similar.

The length of the line that has the coordinate pairs of (-4 1/2,5) and (8 2/3, 5) is 12.16 units.

If two points of coordinates are given then we calculate the distance between them by using the following formulae

To find the length of the line is nothing but the calculation of the distance between two points that are given in the question.

[tex]d = \sqrt{(x_{2} - x_{2} )^{2} +(y_{2} - y_{1} )^{2} }[/tex]

d is the distance between two points.

(x1, x2) and (y2, y1) are the two endpoints of the line.

We can put all the values into the distance formulae and find the length of the line segment.

x1 = -4 1/2 = -3.5, y1 = 5

x2 = 26/3 = 8.6667, y2 = 5

[tex]d = \sqrt{(8.6667-(-3.5))^{2} +(5 - 5)^{2}\\[/tex]

22-ounce package is the best buy as it has the lowest price per ounce.

Step-by-step explanation:

To determine which package is the best buy, we need to calculate the price per ounce of each package:

Price per ounce of 6-ounce package = 1.98 / 6 = $0.33 per ounce

Price per ounce of 14-ounce package = 4.90 / 14 = $0.35 per ounce

Price per ounce of 22-ounce package = 7.04 / 22 = $0.32 per ounce

Therefore, the 22-ounce package is the best buy as it has the lowest price per ounce.

The product of the factors of [tex]65x^2 + 212x - 313[/tex] is equal to the original expression. Lauren may have recognized the expression as a difference of squares and factored it accordingly.

We can first simplify the expression [tex]65x^2 + 212x - 313[/tex] by factoring it:

[tex]65x^2 + 212x - 313 = (13x - 1)(5x + 313)[/tex]

(13x - 1)(5x + 313) = [tex]65x^2 + 212x - 313[/tex]

Therefore, the product of the factors is equal to the original expression.

To see this, we can rewrite the expression as:

[tex]65x^2 - 313 - 212x = (5x)^2 - (2\cdot 5x \cdot 7) + 7^2 - 7^2 - 212x[/tex]

= [tex](5x - 7)^2 - 7^2 - 212x[/tex]

= [tex](5x - 7)^2 - 212x - 49[/tex]

= [tex](5x - 7)^2 - 1^2\cdot 49 - 212x[/tex]

= (5x - 7 - 7)(5x - 7 + 7) - 49 = (5x - 14)(5x) - 49

= 5x(5x - 14) - 49

= 5x(5(x - 2) - 9)

= 5x(5x - 29)

Therefore, the factors of the expression are (5x - 7) and (5x - 29).

Lauren may have recognized the expression as a difference of squares by noticing that the coefficient of the x term (212) is twice the product of the square roots of the first and last terms (sqrt(65) and sqrt(313)), which is a common characteristic of a difference of squares.

The volume of the oblique prism is 75 cm³, which is option D.

An oblique prism is a three-dimensional geometric shape that has two parallel and congruent bases that are connected by parallelogram-shaped lateral faces. Unlike a right prism, the lateral faces of an oblique prism are not perpendicular to the base faces.

The formula for the volume of an oblique prism is given by:

Volume = Base Area × Height

Since the base of the prism is a square, its area is given by:

Base Area = Side × Side = 5 × 5 = 25 square centimeters

Substituting this and the height given as 3 cm in the formula for the volume, we get:

Volume = Base Area × Height

= 25 × 3

We will see that this circle is centered at the point (-5, -49) and has a radius of 1.

For a circle of radius R centered at the point (a, b), the equation is:

(x - a)^2 + (y - b)^2 = R^2

In this case, we have:

given the equation of the circle is

x^2 + y^2 + 10x + 14y + 73 = 0

We can rewrite this as:

(x^2 + 10x) + (y^2 + 14y) + 73 = 0

(x^2 + 2*5*x + 25) + (y^2 + 2*7*y + 49) - 25 - 49 + 73 = 0

(x + 5)^2 + (y + 49)^2 -74 + 73 = 0

(x + 5)^2 + (y + 49)^2 = 1

What is Algebraic expression ?

An algebraic expression is a mathematical phrase that can contain variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. Algebraic expressions are used to represent and solve problems in many areas of mathematics, science, engineering, and finance.

The skew of a dataset refers to the degree to which the distribution of values is asymmetrical. A dataset is said to be skewed if the majority of the values lie on one side of the mean.

In this case, the dataset has a right skew because there are more values on the right side of the distribution (higher values) than on the left side. We can see this by noting that the median (middle value) is 3, while the mean (average value) is slightly higher at 3.375.

If the writer writes 8 more comic strips on the next day, it will increase the maximum value in the dataset from 7 to 8. This will slightly shift the distribution to the right, but the skew will remain right because the majority of the values are still clustered on the right side of the distribution.

However, the effect on the overall skew will depend on the number of comic strips the writer produces on the next day relative to the other values in the dataset. If the writer produces a large number of comic strips relative to the other values, it could shift the distribution to a more symmetrical shape.

What is quadratic equation?

it's a second-degree quadratic equation which is an algebraic equation in x.

a) A quartic function with zeroes -5/2, -1, 7/2, and 3 can be written as the product of linear factors with those zeroes:

f(x) = a(x + 5/2)(x + 1)(x - 7/2)(x - 3)

where "a" is a constant that determines the overall scaling of the function.

b) Two examples of functions that belong to this family are:

f1(x) = 2(x + 5/2)(x + 1)(x - 7/2)(x - 3)

f2(x) = -0.5(x + 5/2)(x + 1)(x - 7/2)(x - 3)

Note that these functions differ only in the value of the constant "a".

c) To find the value of "a" that makes the graph of the function pass through the point (-2,25), we can substitute x = -2 and y = 25 into the equation for f(x):

25 = a(-2 + 5/2)(-2 + 1)(-2 - 7/2)(-2 - 3)

Simplifying this expression:

25 = a(5/2)(-1)(-11/2)(-5)

25 = a(6875/4)

a = 100/6875 = 4/275

Therefore, the equation for the member of the family that passes through the point (-2,25) is:
