The statements that provide support for Chloe's claim are A<0 because A is to the left of zero, B>0 because B is to the right of zero. So correct option is A and F.

Comparison algebra is a branch of algebra that deals with inequalities and comparisons between different quantities or expressions. In comparison algebra, the goal is to determine the relationships between different expressions or quantities, such as whether one expression is greater than, less than, or equal to another expression.

Comparison algebra involves the use of comparison symbols, such as "<" (less than), ">" (greater than), and "=" (equal to), to express these relationships. For example, if we have two expressions, A and B, we can use the "<" symbol to express the relationship that A is less than B, as in A < B.

In comparison algebra, we can also manipulate inequalities and equations in similar ways as we do with regular algebraic expressions. For instance, we can add, subtract, multiply, or divide both sides of an inequality or equation by the same number or expression, while maintaining the inequality's direction.

The statements that provide support for Chloe's claim are:

A. A<0 because A is to the left of zero.

F. B>0 because B is to the right of zero.

Statement A supports Chloe's claim because Point A is to the left of zero on the number line, which means its value is negative. Statement F also supports Chloe's claim because Point B is to the right of zero on the number line, which means its value is positive.

Answer: The formula for compound interest is:

A = P(1 + R/100)^t

where A is the amount after t years, P is the principal amount, R is the rate of interest per annum, and t is the time period in years.

Here, P = Rs. 3,500, R = 8%, and t = 2 years.

So, the amount after 2 years will be:

A = 3,500(1 + 8/100)^2

= 3,500(1.08)^2

= 3,892.32

Therefore, the compound interest for 2 years will be:

CI = A - P

= 3,892.32 - 3,500

= 392.32

Hence, the compound interest on Rs. 3,500 for 2 years at the rate of 8% per annum is Rs. 392.32.

It will take 4.645 months to pay off the loan, which rounds up to 5 months.

Interest rate is the percentage of the principal amount charged by a lender or creditor for the use of borrowed money. In other words, it is the cost of borrowing money, usually expressed as an annual percentage rate (APR) or as a periodic rate for a specific time period.

Given:

Total amount of the loan (A) = $70,000

Monthly interest rate (i) = 0.25% = 0.0025

Monthly payment (P) = $250

We need to find the number of monthly payments (N) needed to pay off the loan.

Using the given formula:

N = (-log(1 - i×A/P))/(log(1+i))

Substituting the values we get:

N = (-㏑(1 - 0.0025×70000/250))/(log(1+0.0025))

N = (-㏑(0.72))/(㏑1.0025))

N = (-(-0.337))-4.308

N = 4.645 (approx.)

Therefore, it will take approximately 4.645 months to pay off the loan, which rounds up to 5 months.

Answer: The area of the door can be calculated as:

Area of door = width x height

= 0.9 m x 2.1 m

= 1.89 square meters

The area of one window can be calculated as:

Area of window = width x height

= 1.5 m x 1.2 m

= 1.8 square meters

Since there are four windows, the total area of the four windows is:

Total area of four windows = 4 x Area of window

= 4 x 1.8 square meters

= 7.2 square meters

Therefore, the total area of the door and the four windows is:

Total area = Area of door + Total area of four windows

= 1.89 square meters + 7.2 square meters

= 9.09 square meters

Hence, the total area of the door and the four windows is 9.09 square meters.

The area of ΔSTU is approximately 6358 cm², to the nearest square centimeter.

We can find the area of ΔSTU using the given side and angles by applying the formula:

Area = (1/2)ab x sin(C)

Where a and b are the lengths of two sides of the triangle and C is the angle between them.

We have one side, s, which is 210 cm. We also have two angles, ∠S = 115° and ∠T = 23°. We can find the third angle, ∠U, by using the fact that the sum of angles in a triangle is 180°:

∠U = 180° - ∠S - ∠T

∠U = 180° - 115° - 23°

∠U = 42°

Now, we have ∠S = 115°, ∠T = 23°, and ∠U = 42°. We can use the Law of Sines to find the other two sides of the triangle. Let side t be opposite ∠T and side u be opposite ∠U. Then:

s / sin(S) = t / sin(T) = u / sin(U)

We can now find t and u using the known values:

t / sin(23°) = 210 / sin(115°) = 90.5

S = 1/2 x 90.5 x 210 x sin  42°

A sequence is a grouping of range numbers, or "terms." There are phrases like 2, 5, but choose 8. Certain narrative arcs can be made to go on forever by choosing to capitalise on a certain pattern that they exhibit. Use the designs 2, 5, 8, and then 3 to lengthen it. In a list of words for words, there exist formulas that show where to look. In mathematics, a sequence is a group of items that are ordered in some way.

Here,

The first three terms in the given sequence are 15, 9, and 27/5.

We must determine the pattern or rule that underlies the sequence in order to determine the tenth word.

=>  9 = 15 * (27/5) / 15

=>  27/5 = 9 * (27/5) / 9

Thus, each term is obtained by multiplying the constant value by (27/5) / 15, which may be written as 9/25.

In order to get the next phrase in the series, we can keep multiplying the preceding term by 9/25 using this constant value:

=>  9 * (9/25)⁷

When we compute this expression, we obtain:

Answer: What is the ratio of pulled-pork sandwiches to barbeque chicken sandwiches at the Greenfield Community Picnic?

Let's call the number of pulled-pork sandwiches "P" and the number of barbeque chicken sandwiches "C". According to the problem, the organizers are making 2 pulled-pork sandwiches for every 5 barbeque chicken sandwiches. This means that:

P/C = 2/5

To simplify this ratio, we can multiply both sides by a common factor that will make the denominators the same. In this case, the smallest common multiple of 2 and 5 is 10, so we can multiply both sides by 10:

10(P/C) = 10(2/5)

Simplifying this expression, we get:

2P = 4C

Dividing both sides by 2, we get:

P/C = 2/4

Simplifying this fraction, we get:

P/C = 1/2

Therefore, the ratio of pulled-pork sandwiches to barbeque chicken sandwiches at the Greenfield Community Picnic is 1:2.

A person would need to buy 60 square yards of carpet for a rectangular room with dimensions of 10 yards by 18 feet.

How to determine the amount of carpet needed for a rectangular room?

To determine the amount of carpet needed for a rectangular room, you need to convert the measurements to the same unit of measurement. Since the carpet is sold in square yards, we need to convert the dimensions of the room to yards.

The length of the room is given in yards, so we don't need to make any conversions for that dimension. However, the width of the room is given in feet, so we need to convert it to yards by dividing by 3 (since there are 3 feet in a yard),

18 feet ÷ 3 feet/yard = 6 yards

So the dimensions of the room in yards are 10 yards by 6 yards.

To find the total area of the room, we need to multiply the length and width,

10 yards × 6 yards = 60 square yards

Therefore, a person would need to buy 60 square yards of carpet for a rectangular room with dimensions of 10 yards by 18 feet.

A reduced radical form is a way of simplifying expressions that contain radicals such as square roots and cube roots, as much as possible. In a reduced radical form, the radical is simplified to its lowest possible terms.

To obtain the reduced radical forms of the expresions, we can proceed with the workings:

1. 3^(√4/9m^2) = 3^(2/3 * 1/3√4m^2) (since √4 = 2)

= (3^(2/3))^(1/3√4m^2)

The BEST group for Ryan to survey would be the 25 fifth grade boys since they are the specific group that he is interested in studying.

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It involves the use of various methods and techniques to gather data from a sample or population and to draw conclusions or make predictions based on that data.

There are two main branches of statistics: descriptive statistics and inferential statistics. Descriptive statistics is the process of summarizing and presenting data in a meaningful way, such as by calculating measures of central tendency (e.g. mean, median, mode), variability (e.g. range, variance, standard deviation), and correlation. Inferential statistics involves using probability theory to make inferences about a larger population based on a sample of data.

Statistics is used in a wide variety of fields, including business, economics, psychology, social sciences, medicine, and engineering. It is often used to test hypotheses, identify trends, and make predictions based on data. The field of statistics has evolved over time, with the development of new techniques and technologies for collecting and analyzing data.

Answer:

(3x + y)(2x + 3)

Step-by-step explanation:

        3y = 3 * y

Common factor = 3

Take out the common factor 2x from the first and second term & take out the common factor 3 from third and fourth term.

6x² + 2xy + 9x + 3y = 2x(3x + y) + 3(3x + y)

Answer:

(-1, -8) is:(x + 7)^2 + (y + 4)^2 = 52

Step-by-step explanation:

i literally just learned this today so here we go:

The equation of a circle with center (h, k) and radius r is given by:

(x - h)^2 + (y - k)^2 = r^2

We are given the center of the circle as (-7, -4), so we can substitute these values for h and k:

(x - (-7))^2 + (y - (-4))^2 = r^2

(x + 7)^2 + (y + 4)^2 = r^2

We also know that the circle contains the point (-1, -8).

We can substitute these values for x and y, and solve for r:

(-1 + 7)^2 + (-8 + 4)^2 = r^2

36 + 16 = r^2

r^2 = 52

Substituting this value of r^2 into the equation for the circle, we get:

(x + 7)^2 + (y + 4)^2 = 52

Therefore, the equation of the circle with center (-7, -4) containing the point (-1, -8) is:(x + 7)^2 + (y + 4)^2 = 52

Nick's monthly mortgage payment is $482.16.

What is statistics?

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data.

To calculate Nick's monthly mortgage payment, we first need to find out the amount he borrowed from the bank, which is 75% of the purchase price:

$145,500 x 0.75 = $109,125

Next, we need to calculate the monthly interest rate. We can do this by dividing the annual interest rate (3.15%) by 12:

3.15% / 12 = 0.002625

Now we can use the following formula to calculate Nick's monthly payment:

M = P [ [tex]i(1 + i)^{n}[/tex] ] / [ [tex](1 + i)^{n}[/tex] – 1]

Where:

M = Monthly payment

P = Loan amount (principal)

i = Monthly interest rate

n = Number of payments (in months)

Plugging in the values we have:

M = $109,125 [ 0.002625 [tex](1 + 0.002625)^{360}[/tex] ] / [ [tex](1 + 0.002625)^{360}[/tex] – 1]

Probability is a way to gauge how likely or unlikely something is to happen. It is a number between 0 and 1, where 0 denotes an improbable event and 1 denotes an inevitable one.

Since the sample size is large (n = 70), we can use the Central Limit Theorem to approximate the sampling distribution of the sample mean as normal with mean μ = 5 and standard deviation σ/sqrt(n) = 2/sqrt(70) ≈ 0.24.

Now we want to find the probability that y, the sample mean, is between 5.1 and 5.7. We can use the standard normal distribution to do this by standardizing y:

z = (y - μ) / (σ / sqrt(n)) = (y - 5) / 0.24

The probability that y is between 5.1 and 5.7 is equivalent to the probability that z is between:

z1 = (5.1 - 5) / 0.24 ≈ 0.42

and

z2 = (5.7 - 5) / 0.24 ≈ 2.92

Using a standard normal distribution table or calculator, we can find that the probability of z being between z1 and z2 is approximately 0.4292.

Therefore, the probability that y is between 5.1 and 5.7 is approximately 0.4292.

It would take approximately 1,980 minutes (33 hours) for the tester to eat all possible cheeseburgers.

There were 145 adult tickets and 290 child tickets sold at Tuesday night's Disney on Ice performance.

Let's assume that the number of adult tickets sold is "x" and the number of child tickets sold is "y".

From the problem, we know that the price of an adult ticket is $6.50 and the price of a child ticket is $2.50.

Therefore, the total revenue from adult tickets is 6.5x and the total revenue from child tickets is 2.5y.

We also know that the total attendance for the evening was 435 people, so:

x + y = 435

Finally, we know that the box office brought in $1667.50 in revenue for the evening, so:

6.5x + 2.5y = 1667.5

First, we can use the first equation to solve for one of the variables in terms of the other:

y = 435 - x

Substituting this expression for y into the second equation, we get:

6.5x + 2.5(435 - x) = 1667.5

Simplifying and solving for x, we get:

6.5x + 1087.5 - 2.5x = 1667.5

4x = 580

x = 145

To find the number of child tickets sold, we can use the equation we derived earlier:

y = 435 - x

y = 435 - 145

y = 290

Therefore, 290 child tickets were sold.
