PLEASE HELP! 15 POINTS! What are the factors of the expression −4(a+b )?
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. :)
What is the quotient and remainder of 26 divided by4
Answer:
6 with a reminder of 2 :)
4 is the quotient and 2 is the remainder when 26 divided by 4.
What is Division?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
26/4
26 we can split as 24+2
24 is divided by 6 which results 4 and 2 is the remainder. So 4 is the quotient and 2 is the remainder
Hence, 4 is the quotient and 2 is the remainder when 26 divided by 4.

William earned $3,200 per month as a teacher for the ten months from September to June. Then he took a job as a barista at a local café, where he earned $2,000 per month during July and August. What was his average monthly pay for the 12 months?
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:
An adult ticket costs £7.
A child ticket costs £2.
Step-by-step explanation:
Let a represent the cost for adults and let c represent the cost for children.
Family 1 has a total of 2 adults and 3 children. Together, it cost them £20.
In an equation, this is:
[tex]2a+3c=20[/tex]
Family 2 has a total of 1 adult and 4 children. It cost them £15. In an equation, this is:
[tex]a+4c=15[/tex]
We know have a system of equations. Solve it. We can use the substitution method.
First, subtract both sides by 4c in the second equation:
[tex]a+4c=15\\a=15-4c[/tex]
Substitute this into the first equation:
[tex]2a+3c=20\\2(15-4c)+3c=20[/tex]
Distribute:
[tex]30-8c+3c=20[/tex]
Add:
[tex]30-5c=20[/tex]
Subtract 30 from both sides. The left cancels:
[tex]-5c=-10[/tex]
Divide both sides by -5:
[tex](-5c)/-5=(-10)/-5\\c=2[/tex]
Thus, the cost of a child ticket is £2.
Substitute 2 for c into the equation we manipulated at the start:
[tex]a=15-4c\\a=15-4(2)\\a=15-8=7[/tex]
Thus, the cost of an adult ticket is £7.
Answer:
Adult ticket= $7
Child Ticker=$2
Step-by-step explanation:
Family 1: 2x+3y=20
Family 2: x+4y=15
2x+3y=20
x+4y=15
Multiply by 2
2x+3y=20
-(2x+8y=30)
Change the signs
2x+3y=20
-2x-8y=-30
Eliminate x
-5y=-10
Divide both sides by -5
y=2<---- Price per children
Substitute the value of y
x+4(2)=15
x+8=15
x=15-8
x=7 <----Price per adult
Check:
Substitute the values of x and y to family 1
2(7)+3(2)=20
14+6=20
20=20
7+4(2)=15
7+8=15
15=15
Explain how you would plot (3,-4) on a coordinate plane.
Answer and Step-by-step explanation:
We are given a coordinate :
( 3 , -4 )
The first number within a coordinate means the x axis, meaning it moves either left or right.
While the second number within a coordinate means the y axis, meaning it moves up or down.
If a number is positive, it increases, if it is negative, it decreases.
So let's take a look at the first number 3, it is positive and the x axis number, meaning you should say "Moving right on the x axis 3 times"
Now for -4, it is negative and the y axis, meaning you should say "Moving down on the y axis 4 times"
Your final phrase should be :
"(3,-4) is moving right on the x axis 3 times, and moving down on the y axis 4 times"

What is Dennis's speed? miles per hour Dennis is driving down the East Coast of the United States. He starts in Boston and drives through Hartford Corecticut which is approximately 101 miles away from Boston. He contimies on from Hartford to Baltimore. Baltimore is approximately 410 miles away from Boston. Determine Dennis's average speed from Hartford to Baltimore if that noition of his trip takes 5 hours.
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:
[tex]\text{Average Speed = }\dfrac{\text{Total Distance traveled}}{\text{Total Time Taken}}[/tex]
So,
[tex]\text{Average Speed = }\dfrac{309}{5}\\\Rightarrow \text{Average Speed = }\bold{61.8\ miles/hr}[/tex]

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.

Please hurry and answer
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).
What is an Expression?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).

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

some irrational numbers are integers true or false
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.
Is the statement true or 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.

Write the repeating decimal 0.515151515151... as a fully simplified fraction.
=================================================
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.
