Sarah left the house at 12:15 p.m. to go to the store. She spent $42.20 on 2 books for her children and she spent $5.67 on a toys for her dog, Rover. Sarah arrived home at 1:00 p.m. How much did Sarah spend on each book
Answer:
Step-by-step explanation:
Given parameters:
Time of going out = 12:15pm
Amount spend on two books = $42.20
Amount spend toys = $5.67
Time of arrival = 1:00pm
The amount Sarah spent on each of the two books;
= [tex]\frac{total amount spent on the books }{number of books}[/tex]
Amount spent on each books = [tex]\frac{42.20}{2}[/tex] = $21.1 per book
The relevant information to solve this problem are the number of books and the cost of the book.

Answer:
After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25
Step-by-step explanation:
The given expression is:[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex]
First I solve the expression, and then will point the error
[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)\\Converting \ \div \ sign \ into \ \times the \ term \ is \ inverted\\=0.38 \times 3 \times(-20)\times5\times(-1/8)\\=0.38\times 3 \times-20\times5\times-1/8\\=1.14 \times-20\times5\times-1/8\\=-22.8\times5\times-1/8\\=-114\times-1/8\\=\frac{-114}{-8}\\=14.25[/tex]
So, the mistake Mia did was when she inverted division sign into multiplication, she didn't invert the term next to division sign.
The step she did was: [tex]0.38 \times 5 \times(1/20)\times3\times(-8)[/tex]
While the correct step was: [tex]0.38 \times 3 \times(-20)\times5\times(-1/8)[/tex]
After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25

Step-by-step explanation:
1. What is matter
2. Write the states of matter with three examples.
Answer:
1.Matter is the "stuff" that makes up the universe — everything that takes up space and has mass is matter. All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons
2.Matter can exist in one of three main states: solid, liquid, or gas.
Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.
Liquid matter is made of more loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained.
Step-by-step explanation:
Answer:
Matter is defined as anything that has mass and takes up space. The types of matter are solids, liquids, gases, and plasma. An example of solids are the desks in school,your bones, or your house. An example of liquids is the ocean, lemonade, or blood. Gases can be hydrogen, carbon dioxide, or oxygen. Plasma can be stars.

how do you find areas of shapes
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

I am a six digit number. One of my sevens is worth 700,000. The other seven is worth 1/10 as much. My eight is worth eight 100s. My nine is worth 90. My other digits are zero. What number am I?
Answer:
The six digit number is 7,70,890
Step-by-step explanation:
Six digit number
One of my seven is = 700,000
Other seven is 1/10 of 700,000 = 70,000
Eight is worth 8 100s = 800
Nine is worth 90 = 90
Other digits are zeros = 0
Upon adding all these we get = 7,70,890
The six digit number is 7,70,890
White people are literally the most racist people on earth! They are 63% more racist then any other race.
Answer:
yep
Step-by-step explanation:
Answer:
what you just said is racist in itself, it is also wrong. If you put 1 million white people in a room with 1 million black people statistics prove there will be more racist people of color. The reason why there are more white racist people world wide is because there are more white people than any other race alive to this day, so if you want to be smart about it you would know how to make it even. It's also 30% as well compared to 39% of racist black people.

John gets a new job and receives a $500 signing bonus. After that, he makes $200 a day. How much money does he make after 4 days?
Answer:
John makes a total of $1,300.
Step-by-step explanation:
We know that before his bonus, John already has $500. Then, he gets $200 every day for 4 days.
200 x 4 = $800
So, over the course of those 4 days, Johnny makes $800. Now, let's add this to the rest of his money.
800 + 500 = $1,300
Therefore, John makes a total of $1,300.

What two numbers multiply to 11 and add to -12
Answer:
-11 and -1
Step-by-step explanation:
if you multiply -1 and -11, hte negatives will cancel out and it will be positive 11
if you add -11 and -1 the answer will be -12
The two numbers whose multiplication will give 11 and the add will be -12 are -1 and -11.
A quadratic equation is an algebraic expression whose power is raised to the second degree.
Mathematically, it can be expressed as:
ax² + bx + c = 0
For more examples, we can have x² -12x + 11 = 0
The way this is solved is that we are going to look for two numbers, in which:
the multiplication of these two numbers will be = 11the addition of those two numbers will be = -12Therefore, the two numbers are -1 and -11
SO, our quadratic equation can be re-written as:
x² - 1x - 11x + 11 = 0
x(x - 1) -11(x - 1) = 0
(x - 11 ) (x - 1) = 0
