,Alice, Raul, and Maria can make 1 whole batch of a dozen cookies together using the ingredients they brought.
To determine how many whole batches of a dozen cookies they can make, we need to compare the amount of flour and butter they have with the required amounts for each batch of cookies.
Let's calculate the total amount of flour and butter each student brought:
Alice:
Flour: 2 cups
Butter: 1/4 cup
Maria:
Flour: 1 1/4 cups
Butter: 3/4 cup
Now let's compare the amounts with the required ingredients for a batch of cookies:
Required amount per batch:
Flour: 3/4 cup
Butter: 1/3 cup
First, let's see how many batches of cookies Alice can make:
Flour: Alice has 2 cups, and each batch requires 3/4 cup. So she can make 2 cups / (3/4 cup) = 8/3 = 2 and 2/3 batches of cookies.
Butter: Alice has 1/4 cup, and each batch requires 1/3 cup. Since she doesn't have enough butter for a full batch, she can't make any batches of cookies with the butter she brought.
Next, let's see how many batches of cookies Maria can make:
Flour: Maria has 1 1/4 cups, and each batch requires 3/4 cup. So she canmake (5/4 cups) / (3/4 cup) = 5/3 = 1 and 2/3 batches of cookies.
Butter: Maria has 3/4 cup, and each batch requires 1/3 cup. So she can make (3/4 cup) / (1/3 cup) = 9/4 = 2 and 1/4 batches of cookies.
Now, to find the maximum number of whole batches they can make together, we take the minimum of the number of batches each student can make:
Alice: 2 and 2/3 batches
Maria: 1 and 2/3 batches
Raul: Not mentioned, so we assume he brought the required ingredients.
The minimum value is 1 and 2/3 batches, which means they can make 1 whole batch of a dozen cookies together.

What is a polynomialA polynomial is a mathematical expression which have a sum of powers in one or more variables with coefficients. The highest power of the variable in a polynomial is called its degree.
We shall divide the polynomial x³ + 3x² - 8x + 140 by x + 7 as follows;
x³ divided by x equals x²
x + 7 multiplied by x² equals x³ + 7x²
subtract x³ - x² from x³ + 3x² - 8x + 140 will result to -4x² - 8x + 140
-4x² divided by x equals -4x
x + 7 multiplied by -4x equals -4x² - 28x
subtract -4x² - 28x from -4x² - 8x + 140 will result to 20x + 140
20x divided by x equals 20

Rounding to the nearest whole number, the membership of the Network Club in 2020 will be approximately 5,564.
Therefore, the correct answer is: E. 5,564.
To calculate the membership of the Network Club in 2020, we can use the continuous growth formula:
[tex]A = P \times e^{(rt)[/tex]
Where:
A is the final amount or membership in 2020,
P is the initial amount or membership in 2010,
e is the mathematical constant approximately equal to 2.71828,
r is the annual growth rate as a decimal,
t is the number of years.
Given:
P = 2,500 (membership in 2010),
r = 8% = 0.08 (annual growth rate),
t = 2020 - 2010 = 10 years (number of years).
Plugging in the values into the formula, we have:
[tex]A = 2,500 \times e^{(0.08 \times 10)}[/tex]

Is not possible to define a radius nor a diameter in a trapezium.
Is it possible to have a radius/diameter in the trapezium?Radius and diameter are two measures defined for circles.
Radius is the distance between the center and any point in the circumference, and the diameter is the distance between two opposite points in the circumference (so it does not need to be 3D to have radius/diameter).
At the same time, a trapezium is not a circle, is a quadrilateral, so it can't have any of these.

Both triangles in the image are similar based on the AAA similarity theorem. The radius of the circle B is therefore calculated as: AB = 12.
What are similar triangles?Similar triangles are geometric figures that have the same shape but may differ in size. They have corresponding angles that are equal and corresponding sides that are in proportion to each other.
Since AD serves as a common tangent, angle BAE is equal to 90 degrees, which is also equal to angle CDE due to being opposite angles.
By the Angle-Angle-Angle (AAA) similarity criterion, triangles ABE and DCE are similar.
Therefore:
AB/EA = DC/ED

The units of measurement for surface area are always cubed.
O False
O True
Answer:
False
Step-by-step explanation:
When calculating volume, units of measurement are cubed. When calculating surface area, units of measurement are squared.
Further explanation:
Let's say you are finding the area of a rectangle. The length is 5in and the width is 7 in.
since you know l*w is area, you need to multiply 5in and 7in. 5*7=35 and then the two units of measurement, in*in=in^2 so 5in*7in=35in^2. the unit is squared not cubed.
The units of measurement for surface area are always SQUARED. Hence the correct answer is FALSE.
In 2-D, the total space covered by any two-dimensional figure is called Area while if we talk about 3-D, the total area of all the outer surfaces when added, sums up to form the Surface Area. Hence, the surface area is the multiplication of any two of the physical quantities.
For example,
Area of a square=(side x side)
=(metre x metre) or (cm x cm) [in terms of units]
= [tex]metre^{2}[/tex] or [tex]cm^{2}[/tex]
Similarly,
Surface Area of cube=6x(side x side) [summation of the area of 6 faces of cube]
=(metre x metre) or (cm x cm) [in terms of units]
= [tex]metre^{2}[/tex] or [tex]cm^{2}[/tex] (again)
Therefore, The units of measurement for the surface area are always SQUARED. Hence the correct answer is FALSE.
When talking of volume, since volume is the amount of space taken by any object or any 3-Dimensional body, the units of measurement of Volume are always cubed. For example, [tex]metre^{3}[/tex] or [tex]cm^{3}[/tex].

The value of a and b in the given complex expression is 1/10 and -1/10 respectively.
This is a problem related to the complex numbers. The complex numbers has a general form of (a+bi) where 'i' is the imaginary number or √-1. The part without an 'i' is called Real Part and the part with an 'i' is called Imaginary Part.
(2i/2+i) - 3i/(3+i) = a + bi

6i + 2i² - 6i - 3i² / (2 + i)(3 + i) = a+bi
(-2 + 3) / (6 + 5i - 1) = s+bi
1 / (5 + 5i) = a+bi
Now we multiply top and bottom by 5 - 5i :
5 - 5i / (5 + 5i)(5 - 5i) = a+bi

f(x) = x^2−4x+2, find the value(s) for x such that f(x)=23.
Step-by-step explanation:
To find the value(s) for x such that f(x) = 23, we can set up the equation:
x^2 - 4x + 2 = 23
To solve this quadratic equation, we need to rearrange it into the standard quadratic form:
x^2 - 4x - 21 = 0
Now, we can solve this equation by factoring, completing the square, or using the quadratic formula. In this case, let's use the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
For the equation x^2 - 4x - 21 = 0, the coefficients are: a = 1, b = -4, and c = -21.
Plugging these values into the quadratic formula, we get:
x = (-(-4) ± √((-4)^2 - 4(1)(-21))) / (2(1))
x = (4 ± √(16 + 84)) / 2
x = (4 ± √100) / 2
x = (4 ± 10) / 2
Now, we have two solutions:
x = (4 + 10) / 2 = 14 / 2 = 7
x = (4 - 10) / 2 = -6 / 2 = -3
Therefore, the values for x such that f(x) = 23 are x = 7 and x = -3.

If sinθ = 5/13 and θ is in Quadrant II, then sin (θ/2) will be equal to [tex]\frac{5}{\sqrt{26}}[/tex]
How to Solve Half-AnglesTo find sin(θ/2), we can use the half-angle identity for sine, which states that:
sin(θ/2) = ±[tex]\sqrt{\frac{(1 - cos\theta)}{2}}[/tex]
Given that sinθ = 5/13 and θ is in Quadrant II, we can determine the value of cosθ using the Pythagorean identity
sin²θ + cos²θ = 1
sinθ = 5/13
sin²θ = (5/13)² = 25/169
cos²θ = 1 - sin²θ = 1 - 25/169 = 144/169
cosθ = ±√(144/169) = ±12/13
Since θ is in Quadrant II, the cosine is negative. Therefore, cosθ = -12/13.
Now, we can calculate sin(θ/2):
sin(θ/2) = ±√((1 - cosθ) / 2) = ±√((1 - (-12/13)) / 2) = ±√((1 + 12/13) / 2) = ±√(25/26) = ±5/√26
Since θ is in Quadrant II, sin(θ/2) will be positive.

The value v of a tractor purchased for $13,000 and depreciated linearly at the rate of $1,300 per year is given by v= -1,300t+13,000, where t represents the number of years since the
purchase. Find the value of the tractor after (a) two years and (b) six years. When will the tractor have no value?
a) the value of the tractor after two years is $10,400.
b) the value of the tractor after six years is $5,200.
To find the value of the tractor after a certain number of years, we can substitute the value of t into the equation v = -1,300t + 13,000.
a) After two years:
Substituting t = 2 into the equation, we get:
v = -1,300(2) + 13,000
v = -2,600 + 13,000
v = 10,400
Therefore, the value of the tractor after two years is $10,400.
b) After six years:
Substituting t = 6 into the equation, we get:
v = -1,300(6) + 13,000
v = -7,800 + 13,000
v = 5,200
Therefore, the value of the tractor after six years is $5,200.
To find when the tractor will have no value, we need to find the value of t when v = 0. We can set the equation v = -1,300t + 13,000 equal to 0 and solve for t:
-1,300t + 13,000 = 0
-1,300t = -13,000
t = -13,000 / -1,300
