There are 1680 ways the teaching assistants can be chosen to grade the exam.

To determine the number of ways the teaching assistants can be chosen to grade the exam, we need to consider the number of choices available for each question and multiply them together.

For the first question, there are eight teaching assistants available. Therefore, there are 8 choices for the first question.

For the second question, since one assistant has already been assigned to the first question, there are seven remaining assistants available. Thus, there are 7 choices for the second question.

Similarly, for the third question, there are six remaining assistants available after two have been assigned to the previous questions. Hence, there are 6 choices for the third question.

Lastly, for the fourth question, there are five remaining assistants available after three have been assigned to the previous questions. Therefore, there are 5 choices for the fourth question.

To determine the total number of ways, we multiply the number of choices for each question:

Total ways = 8 * 7 * 6 * 5 = 1680

Therefore, there are 1680 possible approaches to select the teaching assistants to grade the exam.

Given

Radius and height of cylinder is 8 and 6 inches

Similarly the radius of cone is 12 inches

If they have same volume

Equate the volume of cylinder and cone

\(\Rightarrow \pi r^2h=\dfrac{1}{3}\pi r'^2h'\\\\\Rightarrow \pi \cdot 8^2\times 6=\dfrac{1}{3}\pi \cdot 12^2\times h\\\\\Rightarrow h=\dfrac{64\times 18}{144}\\\\\Rightarrow h=8\ in.\)

The volume of the triangular prism is 216 cubic meters.

To find the volume of a triangular prism, we need to multiply the area of the triangular base by the length of the prism.

Calculate the area of the triangular base.

The base of the triangular face is given as 8 meters, and the height is 9 meters. We can use the formula for the area of a triangle: area = (1/2) * base * height.

Plugging in the values, we get:

Area = (1/2) * 8 meters * 9 meters = 36 square meters.

Multiply the area of the base by the length of the prism.

The length of the prism is given as 12 meters.

Volume = area of base * length of prism = 36 square meters * 12 meters = 432 cubic meters.

Adjust for the shape of the prism.

Since the prism is a triangular prism, we need to divide the volume by 2.

Adjusted Volume = (1/2) * 432 cubic meters = 216 cubic meters.

Therefore, the volume of the triangular prism is 216 cubic meters.

Answer:

the sales tax is 1.036 if you solve in this equation 7.25/100*14.29

Answer: x(5-6x^2)

Step-by-step explanation:

The specific range depends on the material properties and the energy levels involved.

The minimum and maximum frequencies for the acoustic and optic modes depend on the specific system or material under consideration. However, I can provide some general information.

Acoustic Mode:

The acoustic mode refers to the propagation of sound waves or vibrations in a material. In a solid, the acoustic mode can have different types, such as longitudinal and transverse modes.

The minimum frequency for the acoustic mode is typically determined by the size and physical properties of the material. In general, it can be close to zero for macroscopic objects or materials with low elasticity.

The maximum frequency for the acoustic mode depends on factors such as the speed of sound in the material and the characteristic dimensions of the system. It can range from a few kilohertz to several gigahertz.

Optic Mode:

The optic mode is related to the interaction of light with a material. It typically refers to the vibrations of charged particles (such as electrons) in a solid or the oscillations of electric or magnetic fields associated with photons.

The minimum frequency for the optic mode is typically determined by the energy gap between electronic states in the material. For example, in a semiconductor, the minimum frequency is usually in the infrared range.

The maximum frequency for the optic mode is not strictly defined, as it can extend into the terahertz, infrared, visible, ultraviolet, X-ray, and even gamma-ray regions. The specific range depends on the material properties and the energy levels involved.

It's important to note that these frequency ranges are general guidelines and can vary depending on the specific system or material being studied.

After five months of making payments and paying interest, Jillian's ending balance is $1020.10.

What is Interest?

In mathematics, interest is the amount of money that is charged or earned by a lender or borrower, respectively, for the use of borrowed money or investment capital. It is typically expressed as a percentage of the principal amount and can be simple or compound, depending on the terms of the loan or investment.

To calculate Jillian's ending balance after five months of making payments and paying interest, we can use the following steps:

Calculate the balance after each payment:

After the first payment, the balance is 2000 - 200 = 1800.

After the second payment, the balance is 1800 - 200 = 1600.

After the third payment, the balance is 1600 - 200 = 1400.

After the fourth payment, the balance is 1400 - 200 = 1200.

After the fifth payment, the balance is 1200 - 200 = 1000.

Calculate the balance after applying the interest rate each month:

After the first month, the balance is 1800 * 1.02 = 1836.

After the second month, the balance is 1600 * 1.02 = 1632.

After the third month, the balance is 1400 * 1.02 = 1428.

After the fourth month, the balance is 1200 * 1.02 = 1224.

After the fifth month, the balance is 1000 * 1.02 = 1020.

Round the balance to the nearest cent:

After the first month, the balance is $1836.00.

After the second month, the balance is $1632.72.

After the third month, the balance is $1428.73.

After the fourth month, the balance is $1224.24.

After the fifth month, the balance is $1020.10.

Therefore, after five months of making payments and paying interest, Jillian's ending balance is $1020.10.

Multiplication is a mathematical arithmetic operation.

It is also a process of adding the same types of expression to some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given, a bricklayer lays 4 bricks on the first day on the job.

On each day thereafter, he lays three times the number of bricks he laid on the previous day.

And he continued his pattern.

Let x be the number of bricks he laid in the previous day.

Then according to the question,

The number of bricks in total is = 3x

For the second day, x =4

Number of the bricks he laid on the second day = 12

Step 2: Check

Here we see that 15 is NOT equal to 13. Therefore, it is NOT a solution to the equation.

Thus, beginning with a 1 = 5, the formula a n = a n-1 + 7 can be used to recursively find the nth term of the sequence.

A sequence in mathematics is an ordered collection of numbers that is typically defined by a formula or rule. Every number in the series is referred to as a term, and its location within the sequence is referred to as its index. Depending on whether the list of terms stops or continues indefinitely, sequences can either be finite or infinite. By their patterns or uniformity, sequences can be categorised, and the study of sequences is crucial to many areas of mathematics, such as calculus, number theory, and combinatorics. Mathematical, geometrical, and Fibonacci sequences are a few examples of popular sequence types.

given

The sequence's terms are all different by 7 (i.e., 12 - 5 = 19 - 12 = 26 - 19 =... = 7).

The following is a definition of a recursive formula for the nth element of the sequence:

a 1 = 5 (the first term of the series is 5) (the first term of the sequence is 5)

For n > 1, each term is derived by adding 7 to the preceding term, so a n = a n-1 + 7.

Thus, beginning with a 1 = 5, the formula a n = a n-1 + 7 can be used to recursively find the nth term of the sequence. For instance, we have

a_2 = a_1 + 7 = 5 + 7 = 12

a_3 = a_2 + 7 = 12 + 7 = 19

a_4 = a_3 + 7 = 19 + 7 = 26

Answer:

For this problem, you could just multiply $5 by 2 OR you could divide $5 by nine to find your Unit Rate and then multiply that number by 18.

The expressions 2(3a - 2) and 2(5a - 2) are not equivalent. Since these two results are different, we can conclude that Suzanne's claim is incorrect.

To determine if two expressions are equivalent, we need to simplify them and see if they have the same result. Let's start by simplifying the first expression, 2(3a - 2):

2(3a - 2) = 2 * 3a - 2 * 2
          = 6a - 4

Now, let's simplify the second expression, 2(5a - 2):

2(5a - 2) = 2 * 5a - 2 * 2
          = 10a - 4

After simplifying both expressions, we can see that they are not the same. The first expression simplifies to 6a - 4, while the second expression simplifies to 10a - 4.

11 dimes = $1.10

Since he has at most 20 coins , he should have 9 quarters or less.

Because he has no less than $2.75, that means he should have at least 2.75 - 1.10 = $1.65 worth of quarters.

-> He has 1.65 : 0.25 = 6.6 (quarters)

-> He has to have a minimum of 7 quarters.

Malik must have no less than 7 quarters. With his 11 dimes, this gives him a total of 18 coins and a combined value of no less than $2.75.

Firstly, it's important to remember the value of coins in US dollars: a dime is worth $0.10 and a quarter is worth $0.25. Malik has 11 dimes, which is worth $1.10 ($0.10 * 11). To get at least $2.75, Malik needs at least $1.65 more ($2.75 - $1.10).

We can find out the number of quarters needed by dividing the amount needed by the quarter's value. So, Malik needs at least $1.65/$0.25 = 7 quarters.

Therefore, the minimum number of quarters Malik could have given these constraints is 7 quarters. Remember: this balances to provide him with at least $2.75 while keeping his total number of coins no more than 20.
