One day last week, 6 teachers joined of the members of the chess club for a tournament 5 7 after school. Alan counted a total of 31 people at the tournament that day. How many total members are in the chess club at this school?

Answer:  324 squared

Step-by-step explanation:

ok so you do 3 times 3 times 4 times 3 times 3

7x²+9x²-x² = 15x²

use DMAS rule,

The DMAS rule describes the following arrangement of the mathematical function.

D- Division

M - Multiplication

A- addition    

S- subtraction

DMAS rule is used to make the binding order of infix notation explicit for people who are learning to do more than just 'sums' or 'products'.

So, by applying the above rule the solution is as follows:

first, we need to solve addition because there is no division and multiplication

as per the equation, it is the addition function

7x² + 9x² = 16x²

next,

now perform the subtraction function

16x²-x² = 15x²

therefore,

7x²+9x²-x² = 15x²

The packaging 2 uses more material than packaging 1

From the question, we have the following parameters that can be used in our computation:

Package = 12 cans

Material 1 = 3 rows of 4

Material 2 = 6 rows of 2

The packaging uses more material has the greater perimeter

The perimeter is then calculated as

Perimeter = 2 * (Rows + Column)

substitute the known values in the above equation, so, we have the following representation

Material 1 Perimeter = 2 * (3 + 4)

Material 1 Perimeter = 14

Material 2 Perimeter = 2 * (6 + 2)

Material 2 Perimeter = 16

This means that the material 2 uses more material because 16 is greater than 14

The company can choose to package 12 cans one way instead of another because one package can use more material than the other and they need to save cost

The three sides and three angles of a triangle must first be known before you can determine whether it is sine, cosine, or tangent.

The lengths of the sides of the triangle can be determined by employing the trigonometric functions sine, cosine, and tangent with these measurements.

For instance, you can use the sine, cosine, and tangent functions to determine the sides' lengths given the triangle's three angles. The length of the opposite side divided by the length of the hypotenuse is equal to the sine of an angle. The cosine of an angle is the product of the lengths of the sides that are adjacent and the hypotenuse. The length of the opposite side divided by the length of the adjacent side is the tangent of an angle.

The ratios of the sides can be compared to determine whether the triangle is a sine, cosine, or tangent triangle after these lengths have been calculated.

The coefficient of x² is negative 3. Then the value of the constant 'k' will be negative 3.

A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.

The coefficient of x² in the expansion of (x + 3)(x + k)(2x - 5) is -3. Then the product of the expressions is given below.

⇒ (x + 3)(x + k)(2x - 5)

⇒ (2x² + 6x - 5x - 15)(x + k)

⇒ (2x² + x - 15)(x + k)

⇒ 2x³ + x² - 15x + 2kx² + kx - 15k

⇒ 2x³ + (1 + 2k)x² + (k - 15)x + kx

Then the coefficient of x² is negative 3. Then the equation is given as,

1 + 2k = - 3

2k = - 4

k = - 2

The coefficient of x² is negative 3. Then the value of the constant 'k' will be negative 3.

The inequality that describes the problem is x + 6.5 ≥ 10.

This means that the amount of cereal in the box, represented by x, must be greater than or equal to 3.5 cups (10-6.5=3.5) in order to fill the 10-cup container completely.  This means that the box of cereal must have contained at least 3.5 cups of cereal for Clarence to have enough to fill the 10-cup container completely. To calculate the amount of cereal in the box, we can subtract 6.5 from 10 to get 3.5 cupsTo solve this inequality, we add 6.5 to both sides of the equation, resulting in x ≥ 3.5. This means that Clarence needed at least 3.5 cups of cereal in the new box in order to fill the 10-cup container completely.

It is not necessary for all three criteria (SAS, SSS, and ASA) to apply in order for two triangles to be congruent.

In order for two triangles to be congruent, all three pairs of corresponding sides must be equal in length and all three pairs of corresponding angles must be equal in measure. This is known as the "side-angle-side" (SAS) criterion for triangle congruence.

It is possible for two triangles to be congruent using only the SAS criterion, in which case you do not need to use the "side-side-side" (SSS) or "angle-side-angle" (ASA) criteria. However, it is also possible for two triangles to be congruent using either the SSS or ASA criteria, or a combination of all three.

On solving the provided question, we can say that - the interest ant the end of the time will be 45

Multiplying the principal by the interest rate, time, and other factors yields simple interest. Simple return equals principle times interest times hours is the marketed formula. It is easiest to compute interest using this formula. A percentage of the principle balance is how interest is most commonly computed. For instance, he will only pay his portion of the 100% interest if he borrows $100 from a buddy and promises to pay it back with 5% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and when you lend money, you must charge interest. Most of the time, interest is expressed as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.
