The 8th grade math team is having a bake sale as a fundraiser. Alan can make 5 cookies in 2 minutes. Abigail can make 8 cookies in 3 minutes. However, Katie eats 1 cookie every 6 minutes. How many minutes will it take to make 5 dozen cookies.
Answers
Answer: B. 12
Step-by-step explanation:
1) Alan can make 2.5 cookies per min
2) Abi can make 8/3 which is 2.7.
3) overall, 5.2 cookies per minute can be made.
multiple 5.2 x 6 and you get around 31.5?
then subtract =1. you have 30.5, now add onto that number 31.5, which is another 6 minutes. since you're still only subtracting 1, the answer would be above 60, which is 5 dozen, and it only took 12 mins

Option B
One dimensional objects
Answer:
B. One-dimensional objects
A line segment can "grow" from one-dimensional objects. A line segment is a one-dimensional figure that has two endpoints and connects them with a straight path. One-dimensional objects include lines and curves, and a line segment can be a part of a longer line or curve.
Three-dimensional objects (A) are made up of length, width, and height and cannot "grow" into a line segment, but a line segment can be a part of a three-dimensional object, such as an edge or a diagonal.
Zero-dimensional objects (C) are points, which do not have any length, width, or height. A line segment cannot "grow" from a point, but a point can be one of the endpoints of a line segment.

(a) The first time he does this Jack is 1 and Jill is 3. How much does Jill
receive?
(b) How much does Jack receive the following Christmas?
(c) How old will Jack be when he receives £25 from Uncle Fred at Christmas?
Answers
a) Jill receives £45
b) Jack receives £20 the following Christmas
c) Jack will be 5/4 years old, which is equivalent to 1 year and 3 months when he receives £25 from Uncle Fred.
Explain the term years
Years are a unit of time measurement used to quantify the duration of one complete orbit of the Earth around the sun. A year consists of 365 days, except in a leap year when an extra day is added. The concept of a year is used in various fields, including astronomy, geology, and history.
According to the given information
(a) Let's first find the total ratio of their ages:
1 + 3 = 4
So Jack's share will be:
1/4 x £60 = £15
And Jill's share will be:
3/4 x £60 = £45
Therefore, Jill receives £45.
(b) The next Christmas, Jack will be 2 and Jill will be 4. We can use the same ratio to find Jack's share:
2/6 x £60 = £20
So Jack receives £20.
(c) Let x be the age of Jack when he receives £25 from Uncle Fred. We know that:
1/4 x £60 = £25
Multiplying both sides by 4/60, we get:
x = 5/4
So Jack will be 5/4 years old, which is equivalent to 1 year and 3 months, when he receives £25 from Uncle Fred.

Find the minimum or maximum of the function y=x^2-9
Answers
I will be finding the minimum of this parabolic function.
The function y = x^2 - 9 is a parabola that opens upwards, since the coefficient of the x^2 term is positive. Therefore, the minimum value of the function occurs at the vertex of the parabola.
To find the x-coordinate of the vertex, we can use the formula -b/2a, where the quadratic function is in the form y = ax^2 + bx + c. In this case, a = 1 and b = 0, so the x-coordinate of the vertex is -b/2a = -0/(2*1) = 0.
To find the corresponding y-coordinate of the vertex, we can substitute x = 0 into the function, which gives y = 0^2 - 9 = -9.
Therefore, the minimum value of the function y = x^2 - 9 is -9, which occurs at x = 0.
~~~Harsha~~~
The minimum point of this function is located at (0, -9).
Step-by-step explanation:1. Determine whether it's a minimum or maximum.So from plain sight we can tell we're looking for a maximum point, because the coefficient of x² is positive, it's 1. If the function was y=-x²-9, we would be looking at a minimum point.
2. About the minimum...The vertex if the exact point where a quadratic or any pair exponent function will start to either decay or increase, therefore, it will be the minimum or maximum point.
Formula for "x" value of vertex: [tex]\sf x_{Vertex} =\dfrac{-b}{2a}[/tex].
In this equation, a and b are coefficients extracted when the formula is expressed on its standard form.
Standard form of a quadratic equation: ax² + bx + c = 0
➔ You need to substitute the "y" by a "0", and the formula should look like this:
[tex]\sf 0=x^2-9[/tex]
➔ Reorganizing...
[tex]\sf x^2-9=0[/tex]
3. Extracting the coefficients.Let's expand the previous expression:
[tex]\sf x^2+0x_{} -9=0[/tex]
The coefficients are:
a= 1, beacuse "x²" is being multiplied by 1, which is implicit.
b= 0, because "x" doesn't really exist on the simplified equation.
c= -9.
4. Calculate the "x" and "y" locations of the vertex.Now let's calculate the "x" position of the vertex using the formula from step 2:
[tex]\sf x_{Vertex} =\dfrac{-b}{2a}=\dfrac{-(0)}{2(1)}=0[/tex]
Now, the "y" value can be obtained just by substituting "x" by 0 on the argument of the function:
[tex]\sf y=(0)^2-9\\ \\y=-9[/tex]
Therefore, the vertex, or minimum point of this function is located at (0, -9).

A rectangular room is 2 feet
longer than it is wide. Its area is 168 square feet. Set this up as a quadratic equation
Answers
Answer:
x = -14 and x = 12
Step-by-step explanation:
Let x be the width of the rectangular room in feet. Then, according to the problem, the length of the room is 2 feet longer than the width, or x + 2 feet.
The area of a rectangle is given by the formula A = length × width, so we have:
A = (x + 2) × x = x^2 + 2x
We are also given that the area of the room is 168 square feet, so we set A = 168 and get:
x^2 + 2x = 168
This is a quadratic equation in standard form, where 1x^2 + 2x - 168 = 0. We can solve this equation by factoring or using the quadratic formula. This will give us the value(s) of x, which represents the width of the room. Once we have the width, we can find the length by adding 2 feet to it.
And x is : -14 and 12

c. Only pay the minimum amount when possible.
please mark me brainliest
Paying only the minimum amount when possible is not a good strategy for reducing debt. It will likely result in the debt continuing to accumulate and the interest charges increasing over time. Instead, it is important to pay off as much debt as possible each month, starting with the debts that have the highest interest rates. Using an online debt management calculator can help to create a plan for paying off debt more quickly. Finally, it is important to slow or eliminate credit card spending in order to avoid adding to the existing debt.
A theatre contains 457 seats and the ticket prices for a recent play were $54 for adults and $17 for children. If the total proceeds were $14,984 for a sold-out matinee, how many of each type of ticket were sold?

a + c = 457
We also know the cost of the tickets and how much money was made.
$54a + $17c = $14,984
Now, we have a system of equations we can use to solve.
a + c = 457
$54a + $17c = $14,984
Lastly, we will graph this system, see attached. The point of intersection, or where the lines intersect, is our answer.
195 adult tickets and 262 children tickets.
Answer:
Chidden tickets were 262 and adult tickets were 195 tickets
Step-by-step explanation:
Let x = the number of children tickets
Let y = the number of adult tickets.
x + y = 457
17x + 54y = 14984
Use substitution
x + y = 457 Solve for y
y = 457 -x Substitute 457 -x for y in the equation 17x + 54y = 14984
17x + 54y = 14984
17x + 54(457 -x) = 14984 Solve for x Distributer the 54
17x + 24678 - 54x = 14984 Combine like terms
-37x = -9694 Divide both sides by -37
x = 262
The number of children tickets.
x + y = 457 Substitute 262 for x and solve for y
262 + y = 457 Subtract 262 from both sides
y = 195
The number of adult tickets.

A statement which could be true for g is that: D. g(-13) = 20.
What is a domain?In Mathematics and Geometry, a domain can be defined as the set of all real numbers for which a particular function is completely defined.
How to determine the true statement?Since the domain of this function is given by -20 ≤ x ≤ 5, it simply means that the value of x must between -20 and 5. Also, with a range of -5 ≤ g(x) ≤ 45, the value of x must between -5 and 45.
By extrapolating the function, we can deduce that:
g(0) = -2
g(-9) = 6
g(-13) = 20
In this context, we can reasonably infer and logically deduce that based on the answer options provided, g(-13) = 20 is the only statement that could be true for the function g.

The Pythagorean identity is a fundamental trigonometric identity that relates the three basic trigonometric functions: sine, cosine, and tangent, in terms of the unit circle or right triangle.
Proof of cot²(x) - tan²(x) = csc²(x) - sec²(x)The identity you provided, cot²(x) - tan²(x) = csc²(x) - sec²(x), is a trigonometric identity that can be derived from the Pythagorean identity and the reciprocal identities. Here's one way to prove it:
Start with the Pythagorean identity:
sin²(x) + cos²(x) = 1
Divide both sides by sin²(x):
1 + cos²(x)/sin²(x) = 1/sin²(x)
Recall that cot(x) = cos(x)/sin(x) and tan(x) = sin(x)/cos(x):
1 + cot²(x) = csc²(x)
Subtracting sec²(x) from both sides:
cot²(x) - tan²(x) = csc²(x) - sec²(x)
Therefore, cot²(x) - tan²(x) = csc²(x) - sec²(x) is a valid trigonometric identity.

For an investment of 26,245, a quarterly statement reports that the account is 26,292. The statement reports that for the same quarter, the rate of return of the investment was - 0.02%. Given the information regarding the investment quarterly activity, does the reported rate of return seem reasonable?
Answers
No. The reported return rate appears lower than expected.
Rate of returnsTo determine whether the reported rate of return is reasonable or not, we can calculate the expected rate of return based on the investment amount and the ending value of the account.
First, we need to calculate the total number of quarters that have elapsed between the initial investment and the current quarter. Let's assume that the investment has been held for n quarters.
Then, we can use the following formula to calculate the expected rate of return:
Expected rate of return = (Ending value / Initial investment) ^ (1/n) - 1
Plugging in the given values, we get:
n = 1 (since we are only given information for a single quarter)
Initial investment = 26,245
Ending value = 26,292
Expected rate of return = (26,292 / 26,245) ^ (1/1) - 1 = 0.18%
Comparing the expected rate of return of 0.18% with the reported rate of return of -0.02%, we can see that they are quite different. However, it's important to note that a single quarter's rate of return may not be indicative of the overall performance of the investment.
Therefore, while the reported rate of return seems lower than expected, we would need to consider the performance over a longer period of time to make a more informed assessment of the investment's performance.

HELP ME PLEASE! And I already did the first part I need help on the second. (Give me a full explanation NO DECIMALS! Just fractions.)

The amount of chalk that is greater is yellow.
Michelle is correct because more than 1/2 the chalk in the bucket is blue.
How to determine which amount of chalk is greater?In order to determine the amount of chalk that is greater between the amount of yellow chalk and amount of green chalk, we would have to find the difference between them as follows;
Difference = 2/6 - 3/12
Difference = (4 - 3)/12
Difference = 1/12 (positive value)
Similarly, we can determine the greater amount of chalk as follows;
2/6 × 2/2 = 4/12
4/12 > 3/12
Total number of chalks = 2/6 + 5/12 + 3/12
Total number of chalks = (4 + 5 + 3)/12
Total number of chalks = 12/12
Total number of yellow and green chalks = 2/6 + 3/12
Total number of yellow and green chalks = (4 + 3)/12
Total number of yellow and green chalks = 7/12 chalks.
1 - 7/12 = 5/12
7/12 - 1/2 = 6/12 (Michelle is correct).

what is the cosine of angle b
Answers
For the given right angled triangle cosine of angle B is 5√89/89.(option A).
What is right angled triangle?
It is a particular type of triangle having one angle is 90° or right angle. The adjacent sides of the right angle are called base and the perpendicular and the opposite side of 90° is called hypotenuse.
The given triangle is the right angled triangle. The three sides of a right angled triangle are called base, perpendicular and hypotenuse.
In the given figure base= 5 inches and perpendicular = 8 inches
By Pythagoras theorem at first we will find out the hypotenuse. Let the hypotenuse= c inches
For any right angled triangle,
(perpendicular)² +(base)²= (hypotenuse)²
⇒ (8)² + (5)² = (c)²
⇒ 64+ 25 = c²
⇒ c² =89
⇒ c= ±√89
As hypotenuse cannot be negative
So hypotenuse = √89 inches.
Now to find cosine of angle B that is cos B we will use the trigonometric function.
cos B= Adjacent side/ hypotenuse
= 5/√89
= 5√89/89 [ Multiplying the numerator and the denominator by √89 ]
Hence, cosine of angle B is 5√89/89.

For the pattern A, the terms are 6, 11, 16 and 21
For the pattern B, the terms are 24, 20, 16, 12
How to determine the termsTo determine the consecutive terms of the sequence, we need to take note of the rule of each.
From the information given, we have that;
For the Pattern A
Each term is the previous term plus 5
This is represented as;
Pattern A = a + 5,
The first term = 1
Second term = 1 + 5 = 6
Third term = 6 + 5 = 11
Fourth term = 11 + 5 = 16
Fifth term = 16 + 5 = 21
For Pattern B = a - 4
Second term = 28 - 4 = 24
Third term = 24 - 4 = 20
Fourth term = 20 -4 = 16
Fifth term = 16 - 4 = 12

Downtown Mathville is laid out as a 6 x 6 square grid of streets (see diagram below). Your apartment is located at the southwest corner of downtown Mathville (see point H). Your math classroom is located at the northwest corner of downtown Mathville (see point M). You know that it is a 12-block walk to math class and that there is no shorter path. Your curious roommate (we’ll call her Curious Georgia) asks how many different paths (of length 12 blocks – you don’t want to back track or go out of your way) could you take to get from your apartment to the math class. It should also be clear that no shorter path exists. Can you solve Curious Georgia’s math problem?

Yes, we can solve Curious Georgia's math problem using the concept of combinations.
Since we cannot backtrack or go out of our way, we need to take exactly 6 blocks to the north and 6 blocks to the east to reach the math classroom.
This means that we need to choose 6 out of the 12 blocks to go north, and the remaining 6 blocks will be used to go east.
The total number of paths we can take is the number of ways we can choose 6 blocks out of the 12 blocks.
This can be calculated using the combination formula:
[tex]^nC_r[/tex] = n! / r!(n-r)!
where n is the total number of objects, r is the number of objects to choose, and ! represents the factorial function
In this case,
we have n = 12 and r = 6.
The number of paths.
= [tex]^{12}C_6[/tex]
= 12! / 6!(12-6)!
= 924
Therefore,
There are 924 different paths we can take from our apartment to the math classroom, each of which is exactly 12 blocks long and does not backtrack or go out of the way.
