a) The fraction of the stickers that Kate gave to her 6 friends was 1/2.
b) The fraction of Kate's stickers that each friend received from the 1/2 of stickers was 1/12.
What is the fraction?The fraction is the portion or part of a whole.
Fractions can be proper, improper, and complex fractions, depending on the relative value of the numerator and the denominator.
The total number of stickers that Kate possesses = 1/1
The fraction Kate kept for herself = 2/5
The remaining portion of Kate's stickers = 3/5 (1 - 2/5)
The fraction Kate gave to her 6 friends to share equally = 5/6 of 3/5 = 1/2
The fraction of Kate's stickers that each friend received = 1/2 ÷ 6 = 1/12

Which expression is equivalent to 3x2 - 10x - 8?
A-(3x - 4)(x + 2)
B-(3x - 4)(x - 2)
C-(3x - 2)(x - 4)
D-(x - 4)(3x + 2)
Answer:
D
Step-by-step explanation:
3x² - 10x - 8
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 8 = - 24 and sum = - 10
the factors are - 12 and + 2
use these factors to split the x- term
3x² - 12x + 2x - 8 ( factor the first/second and third/fourth terms )
= 3x(x - 4) + 2(x - 4) ← factor out (x - 4) from each term
= (x - 4)(3x + 2)

Answer:
1. Yes, a graph of this relationship will be linear.
2. The y-intercept of the graph is (0, 2).
Step-by-step explanation:
1. The equation will be linear because it can be written in the standard form for the equation of a line. The standard form for the equation of a line is Ax + By = C. Eight can be subtracted from both sides of the equation to get 3x - 4y = -8, which fits the format for standard form. A, B, and C are integers, which includes negative numbers, zero, and whole numbers.
2. 3x - 4y + 8 = 0
3(0) - 4y + 8 = 0
-4y + 8 = 0
-4y = -8

What is sine rule?Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
The formula for sine rule is sinA/a=sinB/b=sinC/c
In the given triangle, ∠B=45°, ∠C=52° and AB=12 units.
By using angle sum property of a triangle,
∠A+∠B+∠C=180°
∠A+45°+52°=180°

integration of {√(4-9x²)/x}dx ??
The antiderivative of the given expression can be found using the substitution method. We'll make the substitution u = 4 - 9x^2, so du/dx = -18x.
Substituting these into the original expression, we get:
∫{√(4-9x²)/x}dx = ∫{√u/x}du = 2√u * ln|x| + C, where C is an arbitrary constant of integration.
Substituting back for u, we get:
∫{√(4-9x²)/x}dx = 2√(4 - 9x^2) * ln|x| + C.
To verify this result, we can differentiate the antiderivative and see if it matches the original expression. Taking the derivative of the antiderivative with respect to x, we get:
d/dx [2√(4 - 9x^2) * ln|x| + C] = -18x√(4 - 9x^2)/x + 2 * (-9x) / (2√(4 - 9x^2)) = (√(4-9x²)/x)
Thus, the antiderivative found is indeed correct.

Hexagonal prism B is the image of
hexagonal prism A after dilation by a scale
factor of 2. If the surface area of hexagonal
prism B is 172 cm2, find the surface area of
hexagonal prism A, the preimage.
The surface area of hexagonal prism A is 9√3x² cm². We are given that hexagonal prism B is the image of hexagonal prism A after dilation by a scale factor of 2.
Therefore, all corresponding sides of prism A and prism B are in the ratio of 1:2. Let the side length of the base of hexagonal prism A be 'x'. Then, the side length of the base of hexagonal prism B is '2x'.
We know that the surface area of hexagonal prism B is 172 cm². Using the formula for the surface area of a hexagonal prism, we can write:
172 = 2(3√3)(2x)^2 + 6(2x)h
where h is the height of hexagonal prism B.
Simplifying this equation, we get:
172 = 24√3x² + 12xh
Dividing both sides by 12, we get:
14.33 = 2√3x² + h
Now, since hexagonal prism B is a dilation of hexagonal prism A by a scale factor of 2, the height of hexagonal prism A is half the height of hexagonal prism B. So, the height of hexagonal prism A is h/2.
Using the formula for the surface area of a hexagonal prism, we can write:
SA(A) = 2(3√3)x² + 6x(h/2)
Substituting h/2 for the height of hexagonal prism A, we get:
SA(A) = 2(3√3)x² + 3xh
Substituting 2√3x² + h/2 for h, we get:
SA(A) = 2(3√3)x² + 3x(2√3x² + h/2)
SA(A) = 6√3x² + 3√3x² + (3/2)xh
Substituting 2√3x² for h in the above equation, we get:
SA(A) = 6√3x² + 3√3x² + (3/2)x(2√3x²)
SA(A) = 9√3x²
Therefore, the surface area of hexagonal prism A is 9√3x² cm².

What is the area of an equilateral triangle where

The area of the equilateral triangle with side length 10 cm is 25 cm².
What is triangle ?
Triangle can be defined in which it consists of three sides , three angles and sum of three angles is always 180 degrees.
To find the area of an equilateral triangle, we need to find the height first. The height of an equilateral triangle is equal to the length of the perpendicular line from the center of the triangle to one of its sides.
To find the height, we can divide the equilateral triangle into two 30-60-90 triangles. The height is equal to half of the hypotenuse of one of these triangles, which can be calculated as:
10 cm / 2 = 5 cm
Now that we have the height, we can find the area of the equilateral triangle as follows:
Area = ½ * base * height
Area = ½ * 10 cm * 5 cm
Area = 25 cm²
Hence, The area of the equilateral triangle with side length 10 cm is 25 cm².

5a - 26 = -10
6a + 46 = 36
If (a,b) is the solution to the system of equations shown above, what is the value of a?
Answer:
Step-by-step explanation:
To solve for the value of "a", we can isolate "a" in one of the equations and then substitute the result into the other equation. Here's how we can do that:
Starting with the first equation:
5a - 26 = -10
5a = -10 + 26
5a = 16
a = 16 / 5
a = 3.2
Now that we know the value of "a", we can substitute it into the second equation:
6a + 46 = 36
6 * 3.2 + 46 = 36
19.2 + 46 = 36
65.2 = 36
This means that the system of equations has no solution, as the values of "a" and "b" can't both satisfy both equations at the same time.
A plane traveled 3900 miles with the wind in 6.5 hours and 3120 miles against the wind in the same amount of time. Find the speed of the plane in still air and the speed of the wind.
Answer:
the speed of the plane in still air is 540 miles per hour and the speed of the wind is 280 miles per hour.
Step-by-step explanation:
Step 1: Define the variables
Let's call the speed of the plane in still air "V". Let's call the speed of the wind "W".
Step 2: Write an equation for the distance traveled with the wind
The distance traveled by the plane with the wind in 6.5 hours can be represented by the equation:
D1 = (V + W) * t
where D1 is the distance traveled, t is the time (6.5 hours), and V and W are the speeds of the plane and the wind, respectively.
Substitute the known values into the equation:
3900 = (V + W) * 6.5
Step 3: Write an equation for the distance traveled against the wind
The distance traveled by the plane against the wind in 6.5 hours can be represented by the equation:
D2 = (V - W) * t
where D2 is the distance traveled, t is the time (6.5 hours), and V and W are the speeds of the plane and the wind, respectively.
Substitute the known values into the equation:
3120 = (V - W) * 6.5
Step 4: Solve for the speed of the wind
We can now use the two equations from Steps 2 and 3 to solve for the speed of the wind.
First, let's rearrange the equation from Step 2 to isolate "W":
W = (3900 / 6.5) - V
Next, substitute this expression for "W" into the equation from Step 3:
3120 = (V - ((3900 / 6.5) - V)) * 6.5
Expand the right side of the equation:
3120 = (V - 3900 / 6.5 + V) * 6.5
Simplify the equation:
3120 = 2V * 6.5 - 3900
Divide both sides of the equation by 2:
1560 = V * 6.5 - 1950
Multiply both sides of the equation by 2:
3120 = V * 13 - 3900
Add 3900 to both sides of the equation:
7020 = V * 13
Divide both sides of the equation by 13:
V = 540
Step 5: Solve for the speed of the wind
Now that we know the speed of the plane in still air, we can use the equation from Step 2 to find the speed of the wind:
W = (3900 / 6.5) - V
Substitute the value of "V" that we found in Step 4 into the equation:
W = (3900 / 6.5) - 540
Simplify the equation:
W = 280
Step 6: Conclusion
Therefore, the speed of the plane in still air is 540 miles per hour and the speed of the wind is 280 miles per hour.
Sarah, James, and Matthew are on a team in a game show. In the game, Sarah always earns $5$ points, Matthew always earns $-2$ points, and James always earns $3$ points. To calculate their team's score, they multiply the first person's score by the second person's score, then subtract the third person's score. If they can choose the order in which they play the game, what is the maximum possible score that their team can earn?
Answer:
17
Step-by-step explanation:
5 x 3 = 15
15 - (-2) = 17
Sarah goes first, James goes second, and Matthew goes third.
