Answer:

Scientific Notation Format: Coefficient

First number in a scientific notation.

The numbers range from 1-10.

Can be greater than or equal to 1 and less than 10.

Scientific Notation Format: Base

This is always 10 and comes after the coefficient.

Scientific Notation Format: Exponent

Comes after the base.

Can be negative or positive.

Scientific Notation Format: Example 1

Example: 0.0000000056 In Scientific Notation Form: 5.6 x 10 to the -9 power.

Scientific Notation Format: Example 2

Example: .00000031 in Scientific Notation Form: 3.1 x 10 to the -7 power.

Scientific Notation Format: Non-Example 1

Non Example: .0000000056 is NOT 56 x 10 to the -9 power.

This is not in scientific notation format because the coefficient is over 10.

Scientific Notation Format: Non-Example 2

Non Example: .0000031 is Not 31 x 10 to the -7 power.

This is not in scientific notation format because the coefficient is over 10.

How to Convert: Standard Form pt.1

Convert 2.1 x 10 to the 5 power to standard form:

1. Take 2.1 and count from the decimal point, 5 times to the right

2. Then after each count add a 0.

3. The number should come out to be 210,000

How to Convert: Standard Form pt.2

Convert 9.8 x 10-4 to standard form:

1. Take 9.8 and count from the decimal point, 4 times to the left. ( since the exponent is negative you go to the left)

2. After each count add a 0.

3. The number should be 0.00098.

How to Convert: Scientific Notation pt.1

Convert 50,600,000,000 to scientific notation.

1. Start at the end and count between each 0, until you reach the 5.

2. The number should become 5.06

3. The final product should be 5.06 x 10 to the 12th power.

How to Convert: Scientific Notation pt.2

Convert 0.000000708 to scientific notation.

1. Start at the decimal point, until you reach between 7 and 0.

2.The number should because 7.08

3. The final product should be 7.08 x 10 to the -7th power. The exponent is negative because the number was less than one.

A shorthand method of writing very small and very large numbers is called scientific notation, in which we express numbers in terms of exponents of 10. To write a number in scientific notation, move the decimal point to the right of the first digit in the number. Write the digits as a decimal number between 1 and 10.

Well first you would start by setting up with a proportion.
In total, the girls paid $54+$22= $76
Thus 1 sister contributed $54/$76=x/100
The other sister contributed $22/$76=x/76
For each proportion, cross-multiply and simplify to get the percentage. The percentage will be the x

10x 6x+8 Solve For X
zhannawk [14.2K]

Answer:

I had x to be 2

Step-by-step explanation:

a square has all it side to be equal

so 10x=6x+8

you will group like terms 10x-6x=8

4x=8 you divide both side by the coefficient of x which is four so X=2

How do I solve for y:<br> x²y² = 12/z²
Vika [28.1K]

Answer:

Y=Srt(12xs^2/z^2)

Step-by-step explanation:

Firstly

We multiply both sides with 1/x^2

We get

Y^2=12/z^2*1/x^2

Y^2=12x^2/z^2

Next: introduce a srt root

We have

Y=srt(12x^2/z^2)

3/4 is added to x, the result is 9/8 . What is the value of x? Enter your answer in the box as a fraction in simplest form. Plea
pentagon [3]
⓵ Write down your complete equation:

x + ¾ = 9/8

⓶ Solve the equation in order to find the value of “x”:

x + ¾ = 9/8
- ¾ - ¾

x = 9/8 - ¾

There a 3 simple steps to subtract fractions:

⒈ Make sure the bottom numbers (the denominators) are the same.

9/8 - ¾ → They don’t have the same denominator.

You need to multiply the top number and the bottom number of ¾ by 2 :

3 (x2) 6
—- = ——
4 (x2) 8

So now you are left with : 9/8 - 6/8

⒉ Subtract the top numbers (the numerators). Put the answer over the same denominator :

9 - 6 = 3 → ⅜

⒊ Simplify the fraction (if needed) :

⅜ → The fraction is already simplified.

⇨ Your answer is: x = ⅜

There you go! I really hope this helped, if there’s anything just let me know! ☻
