Given: Jack's pancake recipe calls for 3 cups of flour and 2 teaspoons of baking powder.
The amount of baking powder required if Jack uses 9 c of flour is to be determined.
Solution:
For 3 c of flour, 2 tsp of baking powder is required
2/3 tsp of baking powder is required for 1 cup of flour.
We must now determine how much baking powder to use with 9 cups of flour.
2/3X9 tsp of baking powder is required for 9 cups of flour.

An object i traveling around a circle with a radiu of 14 centimeter. If in 20 econd a central angle of 1/2 radian i wpt out, what are the linear and angular peed of the object?
The circumference of the circle is given by C = 2 * π * r, where r is the radius. In this case, the circumference of the circle is 2 * π * 14 = 88 cm.
Let's call the linear speed of the object v. Then, in 20 seconds, the object travels a distance of v * 20. This distance is equal to the arc length of the central angle of 1/2 radian:
v * 20 = (1/2) * (C/2π) = (1/2) * (88/2π) = 22/π cm
Solving for v, we get:
v = (22/π) / 20 = 22 / (20π) cm/s
The angular speed ω can be found by dividing the central angle by the time it took to travel that angle:
ω = 1/2 / 20 = 1/40 rad/s
So the linear speed of the object is v = 22 / (20π) cm/s, and the angular speed is ω = 1/40 rad/s.

Five million four thousand three hundred can be written in standard form as 5,004,300.
Write the number five million four thousand three hundred in standard form?5,004,300 = 5 x 10^6 + 4 x 10^3 + 3 x 10^0.The number is composed of five millions (5,000,000), four thousand (4,000) and three hundred (300).In standard form, all numbers are written as a multiple of a power of ten. To convert the number to a multiple of a power of ten, the millions, thousands and hundreds are split apart. The millions is written as 5x10^6. This is because one million is equal to 10^6, and there are five millions. The thousands is written as 4x10^3.This is because one thousand is equal to 10^3, and there are four thousands. The hundreds is written as 3x10^0. This is because one hundred is equal to 10^0, and there are three hundreds. When the three parts are combined, the number is written as 5x10^6 + 4x10^3 + 3x10^0.This can be simplified to 5,004,300.

10. A pipe can fill a cistern in 6 hours. Due to a leak in the bottom it is filled in 7 hours. When the cistern is
full, in how much time will it be emptied by the leak?
Multiple Choice Questions (MCQs)
M
Ti
Answer:
7 hours.
Step-by-step explanation:
This is a rate problem. We can start by using the formula: Rate x Time = Quantity.
The rate at which the cistern is filled is the quantity of water in the cistern divided by the time it takes to fill it. So, the rate at which the cistern is filled is 1 (the cistern is full) / 6 hours = 1/6 cistern/hour.
Similarly, the rate at which the cistern is emptied by the leak is 1 (the cistern is full) / the time it takes to empty it. So, the rate at which the cistern is emptied by the leak is 1 (the cistern is full) / 7 hours = 1/7 cistern/hour.
Since we know the rate at which the cistern is filled and the rate at which it is emptied, we can find the time it takes for the cistern to be emptied by dividing 1 (the cistern is full) by the rate at which it is emptied.
Therefore, the cistern will be emptied in 1 / (1/7 cistern/hour) = 7 hour.

Maria mixes cream and milk in a ratio of 2 parts cream and 3 parts milk.
She uses 8 liters of cream in her mixture.
How many liters of mixture in
all does she make?
How many liters of milk does she use for the mixture?
Answer:
If Maria uses 2 parts cream and 3 parts milk, then for every 2 parts of cream, she uses 3 parts of milk.
Since she uses 8 liters of cream, we can find the total volume of mixture by finding the equivalent volume of milk that she used.
To find the equivalent volume of milk, we multiply the volume of cream by the ratio of milk to cream:
8 liters * (3 parts milk) / (2 parts cream) = 12 liters
So Maria used 8 liters of cream and 12 liters of milk for a total volume of 20 liters.
a particle's position is given by = − 5 meters. at what time is its velocity zero? give your answer to the nearest unit.
At t = ±0.6 seconds its velocity will be zero.
When an object is moving, its velocity serves as a measure of how quickly its location is changing as it is seen from a given point of view and as time is measured using a specific unit of measurement.
The velocity of a particle is the derivative of its position with respect to time, so to find the velocity we need to take the derivative of x with respect to t.
dx/dt = 20 - 15t^2
To find when the velocity is zero, we set dx/dt = 0 and solve for t:
0 = 20 - 15t^2
15t^2 = 20
t^2 = 20/15
t = ±√(20/15)
So, the velocity is zero at approximately t = ±0.6 seconds.

where k is a constant. Give each term in its simplest form.
Given that the coefficient of x is 6 times the coefficient of x,
(b) find the value of k.
Answer:
3/2
Step-by-step explanation:
(a) The first three terms, in ascending powers of x, of the binomial expansion of (2 + kx)² are:
(2 + kx)² = 2² = 4
(2 + kx)² = 2 * 2 * kx = 4kx
(2 + kx)² = 2 * k² x² = 4k² x²
(b) If the coefficient of x is 6 times the coefficient of x, then 6 = 4k. Therefore, k = 6/4 = 3/2.
How do you find D when Diagonalizing a matrix?
The matrix D is important because it is the diagonal representation of the matrix A, which makes it easier to work with and understand.
When diagonalizing a matrix, the goal is to find a diagonal matrix (D) that is similar to the original matrix (A). This means that the matrix D will have the same eigenvalues as the matrix A and will be represented in a more simplified form.
To find the matrix D, you must first find the eigenvalues of the matrix A. These eigenvalues can be found by solving the characteristic equation, which is found by setting the determinant of the matrix (A - λI) to zero, where λ is the eigenvalue and I is the identity matrix.
Once the eigenvalues are found, you can then find the eigenvectors, which are non-zero vectors that satisfy the equation
=> Av = λv,
where v is the eigenvector.
Once you have both the eigenvalues and eigenvectors, you can then arrange them into the matrix D, where the eigenvalues are on the main diagonal and the eigenvectors are the columns.
To make sure that D is diagonal, you may need to scale the eigenvectors so that the entries are integers. This is called normalizing the eigenvectors.

Answer:
x = 1
y = -1
Step-by-step explanation:
y = 3x + 4y
3x + 3y = 0
So, we have 2 equations that are
3x + 3y = 0
x + 2y = -1
Times the second equation by -3
3x + 3y = 0
-3x - 6y = 3
-3y = 3
y = -1
Now put -1 in for y and solve for x
x + 2(-1) = -1
x - 2 = -1
x = 1
Let's check
1 + 2(-1) = -1
1 - 2 = -1
-1 = -1
So, x = 1 and y = -1 is the correct answer.

The height of the tree is approximately 380.04 feet.
Trigonometry involves the study of angles and their relationship to the sides of a right triangle
The tallest tree in the world is a redwood in California and if you're standing 220 feet from the bottom of the tree, you have to look up at a 60-degree angle to see the top. To find the height of the tree, we need to use a concept in mathematics called trigonometry.
The height of the tree can be found using the formula:
Height of tree = Distance from bottom of tree * tan (angle of elevation)
In this case, the distance from the bottom of the tree is 220 feet and the angle of elevation is 60 degrees. Plugging in these values into the formula, we get:
Height of tree = 220 * tan (60)
The value of tan (60) can be found using a calculator or a trigonometry table. The result is approximately 1.732. So the height of the tree can be calculated as:
Height of tree = 220 * 1.732 = 380.04 feet
So in summary, the height of the tree can be found by using the concept of trigonometry and the formula for the height of a tree based on the distance from the bottom of the tree and the angle of elevation to the top of the tree.

a frustum of a right circular cone is formed by cutting a small cone off of the top of a larger cone. if a particular frustum has a lower base radius of 6 inches, an upper base radius of 3 inches, and a height of 4 inches, what is its lateral surface area? (the lateral surface area of a cone or frustum is the curved surface excluding the base(s).)
The lateral surface area of the frustum with a lower base radius of 6 inches, an upper base radius of 3 inches, and a height of 4 inches is 45π sq. inches is 45π sq. inches
The lateral surface area of the frustum is calculated using the given formula:
Lateral surface area of frustum = π × (sum of the radii) × √(difference of radii² + height²)
Lower base radius of frustum = 6 inches
Upper base radius of frustum = 3 inches
Height of frustum = 4 inches
Lateral surface area of given frustum = π × (6 + 3) × √[(6 - 3)² + 4²]
