Solve the equation.
x2 - x - 12 = 0
Answers
Answer:
x = 4 or x = -3
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - x - 12 = 0
The left hand side factors into a product with two terms:
(x - 4) (x + 3) = 0
Split into two equations:
x - 4 = 0 or x + 3 = 0
Add 4 to both sides:
x = 4 or x + 3 = 0
Subtract 3 from both sides:
Answer: x = 4 or x = -3

2. Pencils measuring less than 5 inches: 3 + 2 + 3 = 8 inches in total.
3. False. To determine if more than half of the pencils are 6 inches or shorter, we need to find the total number of pencils and calculate how many of them are 6 inches or shorter.
Total number of pencils = 4 + 3 + 2 + 3 + 7 + 8 = 27
Number of pencils that are 6 inches or shorter = 4 + 3 + 2 + 3 = 12
To find out if more than half of the pencils are 6 inches or shorter, we need to divide the number of pencils that are 6 inches or shorter by the total number of pencils and multiply by 100%:
12/27 x 100% = 44.44%
Since 44.44% is less than 50%, the statement is false.
4. There are three pencils that measure more than 5.5 inches but less than 7.5 inches: 6, 6, and 7. Therefore, the answer is 3 pencils.

Answer:
You will require 9 and 3/4 for the 13 sets of butterfly wings. on the off chance that you were doing that, the absolute cost would be $78. in the event that you expected to have an entire number for yards, you would gather together to 10 and the complete cost would be $80

What is The Diary of Anne Frank?: It's the first, and sometimes only, exposure many people have to the history of the Holocaust.
1. How is this scene the happiest they have been since going into hiding?
In my opinion, this scene is the happiest they have been since going into hiding because the holocaust was very brutal because many individuals got executed and frightened throughout the Holocaust, and opening the gifts was a good way to temporarily forget about their problems.
2. Why does Margot not want to blow out the candles? Why does Mr. Frank say they need to?
Margot does not want to blow out the candles because they are supposed to be left to burn themselves out. Mr. Frank tells her God will understand that they need to conserve their Candles.
3. Explain Peter's prank on Mr. Dussel.
Peter was coming from his room as he was holding something in his coat which turned out to be a towel, but Mr. Dussel thought it was a cat. In the end, he was allergic to his clothes.
4. How does everyone react to Mr. Dussel's cat allergy?
Some seem to laugh at Mr. Dussel's cat allergy, but Mr. Van Dans wants to throw out Peter's cat for always eating their food. Peter said if Mr. Van Daans throws out the cat he will go out with it, but it didn't happen.
5. What happens that makes the mood change?
Something crashes below and they all freeze in horror. Peter tries to reach the lamp, but he can't so he gets up on a chair to try again but he ends up losing his balance and falling and then more steps can be heard below.
6. How was this scene the most scared
they have been since going into hiding?
Because they thought it was the Green Police or the Gestapo that have discovered their hiding place and had come to get them.
7. Describe juxtaposition and explain how this scene is an example of juxtaposition.
A writer can make readers sense of "goodness" in a particular character by placing him or her side-by-side with a character that is
predominantly "evil." In my opinion, this scene is an example of juxtaposition when Peter and Mr.
Van Dans had an argument about the cat, making Peter seem like a positive character while making Mr. Van Dans look like a negative character.
8. Describe how each person reacts in the situation when they are scared.
Mrs. Van Dans was panicking and saying to give the Green Police money
Anne was more concerned for her father because he went to check what happened below while her mother was trying to calmly put her in a state of relief. At some point, Anne asked who is going to look for Mr. Frank and Peter offered to show that he wasn't scared of any danger but Mr.
Dussel pushed Peter away in an angry tone. Mr.
Van Dans was as well calm and seemed to be more focused on what could happen next.
(I hope I did get every one right )
9. List the gifts that Anne gave to each person for Hanukkah. Then show how these gifts represent Anne maturing by saying what the thought or meaning behind each gift is.
1. Margot Frank: A crossword puzzle book / She never loses her temper.
2. Mrs. Van Dans: Hair shampoo / Mrs. Van Dans likes her hair (it doesn't seem to say in this scene, so I don't exactly know)
3. Mr. Van Dans: 2 cigarettes / Mr. Van Dans enjoys smoking (same as above)
4. Mrs. Frank: Ten hours of Anne doing what she says / Anne didn't get the time to repay her (that's what it made me believe)
5. Mr. Frank: A scarf / He found it in the first
scene
6. Mushi: A ball of paper with a string attached to it / For the cat to play with and stay entertained.
7. Peter: a safety razor / Peter was growing a mustache.
8. Mr. Dussel: earplugs / So he won't hear Anne making noise at night
Anne is maturing way faster because of the problems of what happens outside of their hiding as well. Every meaning of the gifts shows that Anne can see every little detail about people which not many kids can do.
l am sorry if l'm late, I had to do some research and listen to the audiobook of the specific scene.
I hope it was helpful! :]
Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
In 2000, Ohio's population was 11.4 million and and increasing by 0.5 million each year. Michigan's population was 9.9 million, increasing by 0.6 million each year. at this rate when will the population of Michigan be greater than the population of Ohio
Answers
Answer:
In 10 years they would be the same, so in 11 years Michigan's population will be greater.
If you add 9.9 by 0.6 10 times you would get an answer of 15.9, and the same with 11.4 plus 0.5... So if you did it one more time Michigan would get 16.5 and Ohio would get 16.4.
So the answer is 11. (10 would equal the same amount)

What is the equation of the line that passes through the point (-3,7) and has a slope of -4/3
Answers
Answer:
y=-4/3+3
Step-by-step explanation:
To find this equation in slope-intercept form you must first put it into point-slope form. Remember point-slope is \(y-y_{2}=m(x-x_{2})\) so plugin the points and slope to get \(y-7=-4/3(x+3)\). Then solve the equation for y.
First, distribute the -4/3
y-7= -4/3x-4
Then, add 7 to both sides
y=-4/3+3
Answer:
y=-4/3x+3
Step-by-step explanation:
y-7=-4/3(x-(-3))
y-7=-4/3x-4
y=-4/3x+3
A right triangle is drawn on graph paper. The length of the legs measure 1.5 centimeters and 2 centimeters. The length of the hypotenuse measures 2.5 centimeters. Write an equation using the triangle’s side lengths to show the Pythagorean Theorem holds true for the triangle.
Answers
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
In this case, let's denote the lengths of the legs as a = 1.5 centimeters and b = 2 centimeters, and the length of the hypotenuse as c = 2.5 centimeters.
The equation using the triangle's side lengths to show the Pythagorean Theorem holds true for the triangle is:
a^2 + b^2 = c^2
Substituting the given values, we have:
(1.5)^2 + (2)^2 = (2.5)^2
2.25 + 4 = 6.25
6.25 = 6.25
Therefore, the equation holds true, confirming that the Pythagorean Theorem is satisfied for the given right triangle.
