In Mrs. Brown’s 75% percent of the class likes to dance .
What are mathematics operations?
A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.
Given:
number of students in Mrs. Brown’s class = 24
number of students likes to dance = 18
Then to find the percent of the class likes to dance we divide 18 by 24 and multiply with 100:
percent of the class likes to dance = (18/24) x 100
percent of the class likes to dance = 75%
Therefore, in Mrs. Brown’s 75% percent of the class likes to dance .

purchase?
After conducting some mathematical operations, we conclude that Lisa purchased 7 pounds of almonds.
What are mathematical operations?A mathematical function known as an operation is one that converts zero or more discrete input values into discrete output values.Depending on how many operands there are, the operation's complexity changes.The four mathematical operations are transformational functions that change numerical inputs into numerical outputs (i.e., another number).These are addition, subtraction, division, and multiplication.So, pounds of Almonds Lisa purchased:
Almonds per pound costs: $3.50Lisa spends the total amount: $24.50Now, calculate the pounds of almonds Lisa purchased as follows:
24.50/3.50 = 7(Refer to the image attached below for calculation)

pls be very specific with steps find x and y
Firstly, we want to start by drawing the triangles
We have this as follow;
For triangle HOT, we have;
We want to get the values of x and y firstly
Since both triangles are congruent, the order of the sides match
Hence, we have angle O and H equal
Thus, we have that;
[tex]\begin{gathered} 5x-1\text{ = 3x+ 17} \\ 5x-3x\text{ = 17+1} \\ 2x\text{ = 18} \\ x\text{ = }\frac{18}{2} \\ x\text{ = 9} \end{gathered}[/tex]Now, to find Y, we need the measure of angle N
Angle N is same as W which we already have as 5y+ 26
Substitute N for Y
Since all the angles of a triangle sum up to 180, we have it that;
[tex]\begin{gathered} 5x-1\text{ + 4x + 9 + }(5y\text{ + 26) = 180} \\ 9x+8+5y+26\text{ = 180} \\ 9(9)\text{ + 5y + 34 = 180} \\ 5y\text{ = 180-34-81} \\ 5y\text{ = 65} \\ y\text{ = }\frac{65}{5} \\ y\text{ = 13} \end{gathered}[/tex]Now, we want the measure of each of the angles;
1. W = N = 5y+ 26 = 5(13) + 26 = 91
2. H = O = 5x-1 = 5(9) - 1 = 44
3. Y = T = 4x + 9 = 4(9) + 9 = 45

The area of Desert A is five times the area of Desert B. If the sum of their areas is 600,000 square miles, find the area of each desert.
The area of Desert A is 500,000 square miles and the area of Desert B is 100,000 square miles.
What is area?
Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Area of a square is side × side.
Let the area of Desert A = x square miles
and the area of Desert B = y square miles
Given that, the area of Desert A is five times the area of Desert B,
i.e. x = 5y ...(1)
and the sum of their areas is 600,000 square miles,
i.e. x + y = 600,000 square miles ...(2)
Putting equation (1) in (2), we get
5y + y = 600,000
or 6y = 600,000 or y = 100,000 square miles
Using equation (1),
x = 5 × 100,000 = 500,000 square miles
Hence, the area of Desert A is 500,000 square miles and the area of Desert B is 100,000 square miles.

what is 30/cos40° rounded to 1 d.p.
The value of 30/cos40° rounded to 1 d.p. (decimal point) is 39.2.
How to round off any decimal number to one decimal place?
When you round to the first decimal place, or to the nearest tenth, the number in the hundredth point place will determine whether you round up or down. If the hundredths digit is a number between 5 and 9, round up to the nearest whole number. If it's a number between 0 and 4, you would "round down" by keeping the tenths place the same.
We have 30/cos40°
Value of 30/cos40° = 30/0.766044 = 39.162241 (cos40° = 0.766044)
Since the number in the hundredths place is 6, which is between 5 and 9, we would round the tenth decimal point up to 2.
Therefore, the value of 30/cos40° rounded to 1 d.p. (decimal point) is 39.2.

The value of x is (t - ab)/ad while taking the subject x.
What does it mean when some variable is made the subject?Making x the subject of an equation or formula entails rearranging the equation or formula so that the x variable is equal to the other variables. The variable being calculated is the formula's subject. On one side of the equals sign, it is identifiable as the letter on its own. When changing a formula's subject, we rearrange the formula's components to create a new subject. In other words, alter the operation to do the opposite if you move a term from one side of the equals sign to the other. (An operation's inverse is known as the operation's opposite.)So, t = a(b + dx):
Now, solve taking the subject 'x' as follows:
t = a(b + dx)t = ab + adxt - ab = adx(t - ab)/ad = xx = (t - ab)/adTherefore, the value of x is (t - ab)/ad while taking the subject x.

The point E is plotted on the coordinate grid below. Plot the point E’, the reflection of E over the x-axis.
Answer:
E' will be at (2, -6)
Step-by-step explanation:
Here we are given point E at (2, 6).
A reflection over the x-axis will keep the x coordinate the same while changing the y value to become the additive inverse (the number in which adding to the current value will get you zero). In this case, it is -6.
E (2,6) --> E' (2, -6)
Another way of thinking of it is reflecting on the x-axis while change the value from (x, y) to (x, -y).

Given the rigth triangle, you have to determine the length of the missing side marked with an x.
To do so you have to apply the trigonometric functions, these are calculated as:

what are the account titles needed for statement of cash flows
A cash flow statement is divided into three sections: operating activities, investments, and financial activities.
What is cash flow?The net balance of money coming into and going out of a business at a particular period is referred to as cash flow. A firm constantly receives and expends cash. For instance, when a retailer buys merchandise, money leaves the company and goes to its suppliers.
According to question:
A cash flow statement is divided into three sections: operating activities, investments, and financial activities.
Operating activities: Cash flow activities that either produce income or keep track of the funds used to produce a good or service are referred to as operating activities. Inventory transactions, interest and tax payments, employee paychecks, and rent payments are all examples of operational business activity. This section does not cover any additional sources of cash flow, such as investments, debts, or dividends.
Investment activities: The cash flow statement's second column lists profits and losses resulting from investments in assets like property, plant, or equipment (PPE), demonstrating how the company's overall cash position has changed. Analysts look for changes on a cash flow statement when they want to determine the company's investment in PPE.
Financial activities: The cash flow between the company's owners and creditors is tracked in the third section of the cash flow statement. Transactions involving debt, stock, and dividends are all considered financial operations. In these transactions, the receipt of capital (from lenders or investors, for example) triggers the recording of incoming cash, and the payment of dividends triggers the recording of outgoing cash.

What are the population and sample?It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.

Find the value of x And y. State the Theron’s you used.
Answer:
x = 5, y = 13
Step-by-step explanation:
Solve for x:
42 = 8x + 2
40 = 8x
x = 5
This is solved using the alternate interior angles theorem, which states that alternate interior angles (in this case, the 42-degrees and 8x + 2 degree angles) are the same.
Solve for y:
180 = 42 + 6(2y - 3)
180 = 42 + 12y - 18
180 = 24 + 12y
156 = 12y
y = 13
This is solved using the same-side interior angles theorem, which states that same-side interior angles (in this case, the 42-degrees and 6(2y-3)-degree angles) add up to 180 degrees.
