using a comma to separate each factor.
Answer here
Answer:
1,3,11,33
Step-by-step explanation:
33 can be divided by itself, 11,3 and 1 without leaving a remainder.
The factors of 33 from least to greatest is 1, 3, 11, 33.
The factors of 33 are the numbers that, when multiplied by another number, result in 33.
The factors of 33 are:
33 = 1 x 33
33 = 3 x 11
So, the factors are:
1, 3, 11, 33
Now, the least factor is 1 and Greatest factor is 33.
Thus, the factors of 33 from least to greatest is 1, 3, 11, 33.

On Saturday morning, it took Jennifer 3.6 hours to drive to her mother's house for the weekend. On Sunday evening, due to
heavy traffic, it took Jennifer 4 hours to return home. Her speed was 5 mi/hr slower on Sunday than on Saturday. What was
her speed on Sunday? Do not include units in your answer.
Provide your answer below:
FEEDBACK
Answer:
Speed of Jennifer on Sunday [tex]=45[/tex] mi/hr
Step-by-step explanation:
Let speed of Jennifer on Saturday be x mi/hr
On Saturday morning, it took Jennifer 3.6 hours to drive to her mother's house for the weekend.
Distance travelled by Jennifer on Saturday = Speed × Time [tex]=3.6x[/tex] miles
Speed of Jennifer on Sunday = [tex](x-5)[/tex] mi/hr
On Sunday evening, due to heavy traffic, it took Jennifer 4 hours to return home.
Distance travelled by Jennifer on Sunday = Speed × Time [tex]=4(x-5)[/tex] miles
As distance is obviously same on both Saturday and Sunday,
[tex]3.6x=4(x-5)\\3.6x=4x-20\\20=4x-3.6x\\20=0.4x\\x=\frac{20}{0.4}\\ x=50[/tex]
Therefore,
Speed of Jennifer on Sunday = [tex](50-5)=45[/tex] mi/hr

Write the equation in slope-intercept form: 6x + 2y = 10.
Answer: y=-3x+5
Step-by-step explanation:
6x+2y=10
Solve for y
2y=-6x+10
y=-3x+5
Answer: y = -3x + 5
Step-by-step explanation:
Slope intercept form is y = mx + b so all you need to do is put the equation into that format.
6x + 2y = 10
2y = 10 - 6x
y = -3x + 5

Janie is three years younger than her brother chad the sum of their ages is 27 how old is Janie
Answer:
Janie is 12
Chad is 15
Step-by-step explanation:
27 - 3 = 24
24 : 2 = 12
12 + 3 = 15 (Chad)
27 - 15 = 12 (Janie)
Janie is three years younger than her brother Chad and she is 12 years old
Janie is 3 years younger than her brother Chad.
let
Chad age = x
Janie age = x - 3
The sum of there ages is 27. Therefore,
x + x - 3 = 27
2x - 3 = 27
2x = 30
divide both sides by 2
x = 30 / 2
x = 15
Chad age = 15 years
Janie's age = 15 - 3 = 12 years

Elena wants to prove that the measures of the 3 angles in a triangle always

My best explanation to this question is:
Elena has summed the total of all three angles in the straight angle to get 180°; <DAB, <BAC , and <CAE. But this does not mean a total of three angles will ALWAYS equal 180°. If one angle is greater than the other two, then there is a possible chance the angle will not be 180°. If the angles are scalene, then there is a greater chance the angle may not be 180°.
This may be wrong, so you don’t have to come up with my response exactly, just modify it to what you need. Wish you luck.
The measures of the 3 angles in a triangle always sum to 180 degrees.
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
We have to determine the prove that the measures of the 3 angles in a triangle always sum to 180 degrees.
We have been given that angles as
∠ DAB, ∠ BAC, and ∠ CAE.
Each 180-degree rotation takes line BC to a parallel line. So line DA is parallel to BC and line AE is also parallel to BC.
There is only one line parallel to BC that goes through point A, so lines DA and AE are the same lines.
Since line DE is parallel to line BC,
∵ alternate interior angles are congruent.
This represents that angle BAD also measures b" and angle CAE also measures c'. D
Since DE is a line, the 3 angle measures at point A would sum to 180 degrees.
So a + b + c = 180.
The fact that this explanation is dependent on the triangle we started with indicates that any triangle's sum of its three angles is always 180 degrees.
Therefore, the measures of the 3 angles in a triangle always sum to 180 degrees.

put the variables to one side and numbers to the other side
then divide 4 from each side
now you have the answer
Answer: -9
Step-by-step explanation:
To solve the equation, isolate the variable, then use basic arithmetic.
Subtract 4x on both sides to obtain the equation:
-12 = 4x + 24
Subtract 24 on both sides to isolate 4x, and obtain the equation:
-36 = 4x
Finally, divide both sides by 4 to obtain the following:

1) Mrs.Galicia sells online math and reading games. His revenue for each game (in dollars) is modeled by the given equations, where x is the number of days since the games went on sale.
Math Game: M(d)=x^2-9x-10
Reading Game: R(d)=2x+10
Solve the system algebraically. After how many days is the revenue for each game the same? Show your work and explain your answer.
Step-by-step explanation:
Given the following expression;
Math Game: M(d)=x^2-9x-10
Reading Game: R(d)=2x+10
x is the number of days since the games went on sale
In order to determine after how many days the revenue for each game wil be the same, we will equate M(d) to R(d)
M(d) = R(d)
x^2-9x-10 = 2x+10
x^2-9x-10 -2x-10 = 0
x^2-11x-20 = 0
factorize
x = 11±√121-4(-20)/2
x = 11±√121+80/2
x = 11±√201/2
x = 11±37.16/2
x = 11+37.16/2
x = 48.16/2
x = 24.06
Hence the revenue for each game will be the same after 24 days
It takes about 13 days for the revenue for each game the same.
Revenue is the amount of money made from selling a particular amount of products.
Given that the revenue is given by:
Math Game: M(d)=x²-9x-10
Reading Game: R(d)=2x+10
For both games to have the same revenue, hence:
M(d) = R(d)
x² - 9x - 10 = 2x + 10
x² - 11x - 20 = 0
x = -1.6 or x = 12.6
Since the number of days cannot be negative, hence it takes about 13 days for the revenue for each game the same.

Susan can read 72 words in One-third of a minute. Which statement is correct? She can read 24 words per minute, because 72 divided by One-third is equal to 24. She can read 24 words per minute, because 72 times One-third is equal to 24. She can read 216 words per minute, because 72 divided by One-third is equal to 216. She can read 216 words per minute, because 72 times One-third is equal to 216.
Answer:
The answer is
"She can read 216 words per minute because 72 divided by One-third is equal to 216."
Step-by-step explanation:
Given the statement
Susan can read 72 words in One-third of a minute ....pause
Whats is one-third of a minute
it is expressed as 1/3*60=20sec
so Susan can read 72 words in 20 second
this means that in a minute she can read
72+72+72 words= 216 word since 20sec*3 is 1 minute
alternatively
[tex]=\frac{72}{\frac{1}{3} }[/tex]
we then multiply 73 with the inverse of the denominator

The local library has a children’s section with picture books and chapter books. The ratio is 2:3. If there are a total of 500 books in the children’s section, then how many chapter books are in the section?
Answer:
300, I think.
Answer:
there are 300 chapter books in the children's section
Step-by-step explanation:
the way you'd solve these kinds of problems is to turn it into an equation.
the ratio of 2:3 with a total of 500
becomes
2x + 3x = 500
2x + 3x = 500
combine like terms
5x = 500
divide both sides of the equation by 5
5x/5 = 500/5
x = 100
now, substitute x in the original equation.
2x + 3x = 500
200 + 300 = 500
There are 300 chapter books
The seats on the right side of the school bus fit two students each. The seats on the left side of the school bus can fit three students each. There are 14 rows of seats. Eight students can fit in the very back seat. How many people can ride the bus at one time (Remember to count every person)?
Answer:
79
Step-by-step explanation:
From Question, we are told that, there are 14 rows of seat with is divided into left hand side and right hand side
Seats by the right = fit two people
Seats by the left = fit three people
This means, 1 row of seat can contain 5 persons
The back seat = 8 people can sit comfortably.
Hence, the number of people that can ride the bus at one time =
(14 × 5 people) + 8 people (backseat) + 1 driver
= 70 + 8 + 1
= 79 people

{(−6, 14), (10, 19), (4, -9), (3, 2), (6, −13)}
Answer:
The domain is {-6, 3, 4, 6, 10}
The range is {-13, -9, 2, 14, 19}
Step-by-step explanation:
Any set of ordered pairs has a domain and a range
The domain is the values of x-coordinates of all ordered pairs
The range is the values of y-coordinates of all ordered pairs
∵ The set is {(-6, 14), (10, 19), (4, -9), (3, 2), (6, -13)}
∵ x-coordinates of all points are -6, 10, 4, 3, 6
→ These values are the domain of the set
∴ The domain is {-6, 3, 4, 6, 10}
∵ y-coordinates of all points are 14, 19, -9, 2, -13
→ These values are the range of the set
∴ The range is {-13, -9, 2, 14, 19}
