Mr. Garcia's classroom had 23 students.

Let's denote the number of students in Mr. Cooper's classroom as C and the number of students in Mr. Garcia's classroom as G.

Given that Mr. Cooper's classroom had 5 tables with 4 students at each table, we can write:

C = 5 * 4 = 20

It is also given that Mr. Garcia's classroom had 3 more students than Mr. Cooper's classroom, so we can write:

G = C + 3

Substituting the value of C from the first equation into the second equation, we get:

G = 20 + 3 = 23

Therefore, Mr. Garcia's classroom had 23 students.

The equation p = 8.25 + 3 inches can be used for finding the length p of the plank before chandler cuts it.

Addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

In mathematics, addition is the process of joining two or more integers. The numbers being added are known as addends, and the result or final response obtained after the procedure is known as the total.

From the given data,

The length of the plank cut by the chandler =3 inches

The correct length = 8.25 inches.

So, for finding the value of the length p of the plank before the chandler cuts, we will add the value of the correct length and the length of the plank cut by the chandler.

So, the value of p will be: 8.25+3 = 11.25 inches.

Finally, we have \(2\frac{11}{24}\) lbs of mini shrimps.

Given that;

A catering company needs 8.75 lbs of shrimp for a small party. they buy \(3\frac{2}{3}\) lbs of jumbo shrimps, \(2\frac{5}{8}\) lbs of medium-sized shrimps, and some mini-shrimps.

The total of 8.75th is changed as \(8\frac{3}{4}th\\\)

Sum of  \(3\frac{2}{3}\) +  \(2\frac{5}{8}\) this is bought by the company.

So, to purchase the remaining  \(8\frac{3}{4}th\\\) - \(3\frac{2}{3}\) - \(2\frac{5}{8}\)

We use a common denominator of 24 for the fraction parts.

Change \(8\frac{3}{4}\) as \(8\frac{18}{24}\)

Similarly, convert;

\(3\frac{2}{3}\) as \(3\frac{16}{24}\)

\(2\frac{5}{8}\) as \(2\frac{15}{24}\)

By solving all the above conversions, we get;

\(\frac{42-16-15}{24}\) = 11/24

Considering all the factors together we have \(2\frac{11}{24}\) lbs of mini shrimps.

The square mil area for a 2 inch wide by 1/4 inch thick copper busbar is 500 square mils.

To find the square mil area for a 2 inch wide by 1/4 inch thick copper busbar, we need to multiply the width and thickness of the busbar in mils.

1 inch = 1000 mils

So, the width of the busbar in mils = 2 inches x 1000 mils/inch = 2000 mils

And, the thickness of the busbar in mils = 1/4 inch x 1000 mils/inch = 250 mils

Therefore, the square mil area of the copper busbar = width x thickness = 2000 mils x 250 mils = 500,000 square mils.

Hence, the square mil area for a 2 inch wide by 1/4 inch thick copper busbar is 500,000 square mils.

The amount that store earns is $120. By writing the equation for the given payment of the computer by Rudo, we get the required value.

It is given that, Rudo buys a computer for $920. This is 115% of what the store paid for the same computer.

So, consider the amount paid by the store for the same computer as 'x'.

Then, from the given information we can write that,

$920 = 115% of x

⇒ 920 = 0.15x

⇒ x = 920/0.15 = 800

So, the amount paid by the store for the same computer is $800

Thus, the amount earned by the store on the sale is $920 - $800 = $120.

The sample space for rolling a six-sided number cube is \({1, 2, 3, 4, 5, 6}\)}, representing the six possible outcomes of the experiment.

The sample space for the experiment of rolling a six-sided number cube consists of all the possible outcomes or numbers that can be obtained when the cube is rolled. Since a standard six-sided cube has six faces, each numbered from 1 to 6, the sample space can be represented as     \({1, 2, 3, 4, 5, 6}\)}.

In this case, the sample space is a set containing the individual numbers 1, 2, 3, 4, 5, and 6, which represent the possible outcomes of rolling the cube. Each number in the sample space corresponds to a face of the cube, and when the cube is rolled, one of these numbers will be the result.

It's important to note that each outcome in the sample space is equally likely, assuming the cube is fair and unbiased. Therefore, the probability of obtaining any particular outcome is 1 out of 6 or approximately 0.1667.

By the end of week 52, Westway Company deducted $8,857.60 for Social Security and $2,426.48 for Medicare from Suzle Chan's earnings.

To calculate the deductions made by Westway Company, we'll need to consider the Social Security and Medicare taxes.

Social Security tax:

The Social Security tax rate is 6.2% on income up to $142,800.

Since Suzle Chan earns $3,220 per week, their annual income is $3,220 * 52 = $167,440.

However, the maximum taxable income for Social Security is $142,800.

Therefore, the Social Security tax deduction is $142,800 * 0.062 = $8,857.60.

Medicare tax:

The Medicare tax rate is 1.45% on all income.

The Medicare tax deduction is $167,440 * 0.0145 = $2,426.48.

The decrease in diameter of the bar due to the applied load is -0.005434905d and the final diameter of the bar is 1.005434905d.

A compressive load of 80,000 lb is applied to a bar with a circular section of 0.75 in diameter and a length of 10 in.

if the modulus of elasticity of the bar material is 10,000 ksi and the Poisson's ratio is 0.3.

We have to determine the decrease in diameter of the bar due to the applied load.

Let d be the initial diameter of the bar and ∆d be the decrease in diameter of the bar due to the applied load, then the final diameter of the bar is d - ∆d.

Length of the bar, L = 10 in

Cross-sectional area of the bar, A = πd²/4 = π(0.75)²/4 = 0.4418 in²

Stress produced by the applied load,σ = P/A

= 80,000/0.4418

= 181163.5 psi

Young's modulus of elasticity, E = 10,000 ksi

Poisson's ratio, ν = 0.3

The longitudinal strain produced in the bar, ɛ = σ/E

= 181163.5/10,000,000

= 0.01811635

The lateral strain produced in the bar, υ = νɛ

= 0.3 × 0.01811635

= 0.005434905'

The decrease in diameter of the bar due to the applied load, ∆d/d = -υ

The transformation rule that describes the rotation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

The rule that describes the transformation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

To understand this, let's apply the transformation rule to each vertex of the original parallelogram ABCD:

Point A (2, 5) becomes A' (-5, 2).

Point B (5, 4) becomes B' (-4, 5).

Point C (5, 2) becomes C' (-2, 5).

Point D (2, 3) becomes D' (-3, 2).

By applying the transformation rule, we observe that the x-coordinate of each point becomes the negative of the original y-coordinate, and the y-coordinate becomes the original x-coordinate.

This transformation is a 90-degree counterclockwise rotation about the origin (0, 0) on the coordinate plane. The image parallelogram A'B'C'D' is obtained by rotating the original parallelogram ABCD by 90 degrees counterclockwise.

Visually, this transformation can be seen as the original parallelogram being rotated around the origin, where the x-axis becomes the y-axis, and the y-axis becomes the negative x-axis.

Therefore, the transformation rule that describes the rotation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

Using the table, the slope is 1/2

There are 33,584,224 ordered pairs (a,b) of subsets of {1, 2, 3, 4, 5} such that a ∪ b = {1, 2, 3, 4, 5}.

Let's count the number of ordered pairs (A,B) of subsets of {1, 2, 3, 4, 5} that have A ∪ B = {1, 2, 3, 4, 5}.

First, notice that every element in {1, 2, 3, 4, 5} must be either in A, in B, or in both A and B. Let's count the number of possibilities for each case:

If an element is in A, then it can be one of the 2^5 possible subsets of {1, 2, 3, 4, 5} (since any subset of {1, 2, 3, 4, 5} can be A if we choose the right elements).

This means there are 2^5 possible choices for each of the 5 elements in {1, 2, 3, 4, 5},

for a total of 2^5 * 2^5 * 2^5 * 2^5 * 2^5 = 2^25 possible choices for (A,B) where every element in {1, 2, 3, 4, 5} is in A.

If an element is in B but not in A, then it must be one of the 2^5 - 2 possible subsets of {1, 2, 3, 4, 5} (since it can't be the empty set or {1, 2, 3, 4, 5}).

This means there are 2^5 - 2 possible choices for each of the 5 elements in {1, 2, 3, 4, 5}, for a total of (2^5 - 2)^5 possible choices for (A,B) where some elements are in B but not in A.

If an element is not in A or B, then it must be left out of both A and B. This means there is only one possible choice for each of the 5 elements in {1, 2, 3, 4, 5}, for a total of 1^5 = 1 possible choice for (A,B) where some elements are left out of both sets.

Therefore, the total number of ordered pairs (A,B) of subsets of {1, 2, 3, 4, 5} that have A ∪ B = {1, 2, 3, 4, 5} is:

2^25 + (2^5 - 2)^5 + 1 = 33554432 + 29791 + 1 = 33584224

So there are 33,584,224 ordered pairs (a,b) of subsets of {1, 2, 3, 4, 5} such that a ∪ b = {1, 2, 3, 4, 5}.
