Answer: 0.875
Step-by-step explanation:
The answer that has already been given is perfect in and by itself. I just want to give you some methods for doing these type of questions so that you won’t stagger when you see these type of questions in exams (like the SAT).
Whenever you see such questions, remember the following things. These are conversions of English words to Mathematical tools.
What
=
Any variable like
x
Percent / Percentage / %
=
Divide by 100
of

Multiply
is
=
Put an equal to (
=
) sign
I’ll give you an example through a question.
What percent of 200 is 5?
Ans: Replace English words by mathematical tools according to the rules I told you.
x
( What) /100 ( percent)
×
( of) 200
=
( is) 5
In a refined form,
x
100
×
200
=
5
Calculate x. On calculating, x comes out to be
2.5
So, 2.5 percent of 200 is 5.
Now your question is actually very simple if you follow my rules.
You want 87.5%. By the rules, % means divided by 100. So
87.5
%
=
87.5
100
and now using the same strategy, Ans:
875

Disregard the next section if you know how to convert a decimal to a fraction
Section Starts
First, I’ll write the decimal form. Whenever you divide by a number that is in form of 1 followed by
n
number of zeroes. (here 1 is followed by 2 zeroes), you should shift the decimal point to the left side by n places.
In this case, shift decimal point in 87.5 to the left by 2 places. So this becomes 0.875.
This is the answer in decimal point.
Now simultaneously, I’ll teach you how to convert a decimal into a fraction.
Here, you see 2 types of “numbers”. One to the left side of the decimal point and one to the right side of the decimal point.
Here, left side of decimal point is 0 and right side of decimal point is 875.
Count the number of digits in the number to the right side of the decimal point (Here, the number of digits is 3)
Remove the decimal point and divide the number by a number formed by 1 followed by the “digits” we obtained (i.e. 3).
So, 875/1000. Simplify this, and you get your answer.

Amanda needs to cut a board to use for a project. The board is 10 feet long. She first has to cut off 1 3/4 feet from one end of the board. She then cuts the remaining section of board into 4 equal pieces.
1 3/4x−4=10
1 3/4x+4=10
4x−1 3/4=10
4x+1 3/4=10
Answer: 4x+1 3/4=10
Step-by-step explanation: Took the test. Plus you can check to see if it equals to - 10 = 10 by replacing x with 2 1/16. Example: 4 * 2 1/16 + 1 3/4 =10. So 10 = 10 is a true match.
The given case can be represented as the equation 4x + 13/4 = 10.
What is a system of linear equations?A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.
Given that,
The length of board = 10 feet.
The length of piece that is cut first = 13/4 feet.
Suppose the length of each remaining piece cut into four equal parts is x feet.
Now, the expression for the total length of the board can be given as the sum of the total length of the remaining piece and the the piece that is cut first.
In mathematical form it can be written as,
4x + 13/4 = 10
Hence, the equation for the given case is 4x + 13/4 = 10.

Answer:
x = -2,4
(disclaimer plugging in -2 will give an imaginary number)
Step-by-step explanation:
3[tex]\sqrt{x^2-7}[/tex]=3[tex]\sqrt{2x+1}[/tex]
Divide both sides by 3
[tex]\sqrt{x^2-7}[/tex]=[tex]\sqrt{2x+1}[/tex]
Square both sides to cancel square roots
[tex]x^2-7=2x+1[/tex]
Move all the terms to the left side
[tex]x^2-2x-8=0[/tex]
Use the quadratic formula
[tex]x=\frac{2 +/- \sqrt{(-2)^2-4(1)(-8)}}{2(1)}[/tex]
which gives x= -2,4
OR factor the quadratic
(x-4)(x+2)=0
x= -2,4
The solution of the equation 3 sqrt x^2-7= 3 sqrt 2x+1 is, x = -2,4

What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
here, we have,
3√x²-7=3√2x+1
Divide both sides by 3
√x²-7=√2x+1
Square both sides to cancel square roots
x²-7=2x+1
Move all the terms to the left side
x^2-2x-8=0
Use the quadratic formula
x=2±√2-4(-8)/2
solving we get,
which gives x= -2,4
OR factor the quadratic
(x-4)(x+2)=0
x= -2,4

x/20 - 2/5 = 3/4
Plz help :)
Answer:
x = 23
Step-by-step explanation:
simplify both sides of the equation then isolate the variable.
Answer:
x = 23
Step-by-step explanation:
x/20 + 20 ( -2/5 )/20 = 3/4
combine fractions with common denominator
x - 8/20 = 3/4
Multiply all terms by the same value to eliminate fraction denominators
20 . x - 8/20 = 3/4 = 20. 3/4
Cancel multiplied terms that are in the denominator
x - 8 = 20 . 3/4
Multiply the numbers
x - 8 = 15
Add 8 to both sides of the equation
x - 8 + 8 = 15 + 8
simplify
add the numbers
x = 23

25. Steve's family traveled 3/4 the distance that Mike's family traveled. If Steve's family traveled 18 miles, how far
did Mike's family travel?
Answer:
13.5 miles
Step-by-step explanation:
For this problem you need to find 3/4 of 18. 18x3/4 = 54/4, or 13.5
The total number of miles Steve's family traveled is 24 miles.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Steve's family traveled 3/4 the distance that Mike's family traveled.
Let the total number of miles Steve's family traveled be x.
Now, 3/4 ×x=18
3x=72
x=72/3
x=24 miles
Therefore, the total number of miles Steve's family traveled is 24 miles.

Slope of the line that passes through (5,7) and (7,8)
Answer:

Step-by-step explanation:
To find the slope, you just have to do (y-y₁) / (x-x₁) where x and y are from the same point and x₁ and y₁ are from the same point. So just substitute in the values to get (7 - 8) / (5 - 7) which is -1 / -2 which is 1/2 or 0.5.

b= (b1, b2,b3)
c=( c1, c2, c3) )
solve : a×(b×c)
We are given three vectors each one has its own coordinates. We need to be careful when we multiply two vectors.
For example, b × c = (b1,b2,b3)×(c1,c2,c3) = (b1c1,b2c2,b3c3)
