Answer:

5, 769 ft

Step-by-step explanation:

The difference between the elevations is

5,763 ft - (-6 ft) = 5, 769 ft

An expression that uses integers to represent the difference between the elevations is 5763-(-6).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given that At its highest point, the elevation of a county is 5,763 feet above sea level. At its lowest point, the elevation of the county is 6 feet below sea level.

If the sea level is assumed to be the origin of a graph, then the elevation above sea level will be represented by a positive y-axis, therefore, the elevation of a county is +5,763. While the elevation below sea level will be represented by a negative y-axis, therefore, the elevation of a county is -6.

Thus, an expression that uses integers to represent the difference between the elevations is,

Difference = Elevation above sea level - Elevation below sea level

= 5763 - (-6)

= 5763 + 6

= 5769

Hence, an expression that uses integers to represent the difference between the elevations is 5763-(-6).

Work Shown:

x = 0.515151...

100x = 51.515151....

Subtract the two equations to get 100x-x = 99x on the left side and 51.515151.... - 0.515151... = 51 on the right side. Notice the decimal portions cancel out.

So we end up with 99x = 51 which solves to x = 51/99

This means 51/99 = 0.515151...

Answer:

17/33

Step-by-step explanation:

We first let 0.51 be x.

Since x is recurring in 2 decimal places, we multiply it by 100.

100x=51.51

Next, we subtract them.

100x−x=51.51−0.51

99x=51

Lastly, we divide both sides by 99 to get x as a fraction.

x=51/99

Answer:

$3,000

Step-by-step explanation:

To find his average monthly pay, you have to find the total amount that Willian received in a year by multiplying his monthly salary as a teacher for 10 months and his salary as a barista for 2 months and adding up these numbers. Then, you have to divide the total amount he earned by 12 that is the number of months in a year:

($3,200*10)+($2,000*2)= $32,000+4,000=36,000

$36,000/12=$3,000

According to this, his average monthly pay for the 12 months was $3,000.

Answer:

False

Step-by-step explanation:

Irrational numbers are not integers. All integers are rational numbers.

The statement "some irrational numbers are integers" is false.

Irrational numbers are real numbers that cannot be expressed as fractions or ratios of two integers. They are non-repeating and non-terminating decimal numbers.

Integers, on the other hand, are whole numbers (positive, negative, or zero) without any fractional or decimal components. They can be expressed as ratios of two integers, such as 1/1, -3/1, or 0/1. Integers can also be written as terminating decimals, such as 4.0, -2.00, or 0.

Since irrational numbers cannot be expressed as ratios of integers and integers can be expressed as ratios of integers, it follows that irrational numbers are not integers. Therefore, it is false to say that some irrational numbers are integers.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The total area of the lawn = 925 m²

Before talking to neighbor

Tara mows ( 3/5 ) of total area of the lawn

So ,

The area left for her to mow is = 1 - 3/5

                                                   = 2/5

So , the equation will be

The area for Tara to mow = 2/5 x total area of the lawn

                                           = 2/5 x 925

                                           = 2 x 185

                                           = 370 m²

Hence , Tara have a total of 370 m² lawn left to mow

Answer:

61.8 miles/hr

Step-by-step explanation:

Given that

Dennis starts from Boston and travels to Hartford for 101 miles.

And then he travels towards Baltimore which is 410 miles away from Boston.

Time taken from Hartford to Baltimore = 5 hours

Kindly refer to the image attached for the trip of Dennis and the distance traveled by him.

Point A represents Boston.

Point B represents Hartford.

Point C represents Baltimore.

Distance AB = 101 miles

Distance AC = 410 miles

Actually, we are given that Distance BC is traveled in 5 hours.

Distance BC = AC - AB = 410 - 101 = 309 miles

Average Speed is given as:

4 is the quotient and 2 is the remainder when 26 divided by 4.

A division is a process of splitting a specific amount into equal parts.

The number which we divide is called the dividend.

The number by which we divide is called the divisor.

The result obtained is called the quotient.

The number left over is called the remainder.

26 divided by 4

26 is the dividend

4 is the divisor

Answer:

FV= $95,454.20

Step-by-step explanation:

Giving the following information:

Annual deposit= $2,000

Number of periods= 25 years

Interest rate= 5% compounded annually

To calculate the future value of the annual deposits, we need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

FV= {2,000*[(1.05^25) - 1]} / 0.05

FV= $95,454.20

Let's say imput is i and that output is o.

The formula is 2 ^ i = o

2^0 = 1

2^1 = 2

2^2 = 4

2^3 = 8

2^4 = 16

2^5 = 32

Complete question is;

Identify the type of sampling​ used: random,​ systematic, convenience,​ stratified, or cluster.

To estimate the percentage of defects in a recent manufacturing batch, a quality control manager at General Foods selects every 18th soup can that comes off the assembly line starting with the fifth until she obtains a sample of 40 soup cans

Answer:

Systematic Sample

Step-by-step explanation:

We are told that the quality control manager selects every 18th soup can that comes off the assembly line starting with the fifth until she obtains a sample of 40 soup cans.

Thus, the selection is from a large sample of produce.

This is synonymous with systematic sample because systematic sample can be defined as a type of probability sampling in which sample members from a larger population are selected according to a random starting point but with a set periodic interval.

This resonates with the statement in the question about selecting every 18th soup from the production assembly line.

Answer:

-4, and (a+b) are the two factors

Step-by-step explanation:

-4(a+b)

We have two factors

-4, and (a+b)

Answer:

-4 and a and b/(a+b)

Step-by-step explanation:

When there is a number outside of a parentheses, you want to distribute it inside of the parentheses.  So in this case, -4 is on the outside, so it usually gets distributed it in, which makes it a factor.

Since a and b are getting multiplied by the -4, they are also factors in the equation.  

In a problem like this, if you want to solve it, the number outside the parentheses gets distributed into the numbers in the parentheses.  (It gets multiplied by the numbers).

-4 times a and -4 times b

-4 times a is -4a

-4 times b is -4b

The answer to this problem, if you need it is -4a-4b.  :)
