The Scientific notation of numbers is,

⇒ 3.7 × 10⁻⁴

We have to give that,

A standard form of number is,

⇒ 0.00037

Since Scientific notation is a way of writing very large or very small numbers.

For example; 230,000,000 can be written in scientific notation as

2.3 x 10⁸.

Hence, the Scientific notation of numbers is,

⇒ 0.00037

⇒ 3.7 × 10⁻⁴

−6.4+3.7  is equivalent to 3.7−6.4

Decimal numbers are numbers in which there are commas or decimal points.

The value of each number in decimal numbers is based on a comparison of the number 10

In a decimal system, the numbers have the following consecutive values ​​(the place value of the digits in a number): hundred thousands, ten thousands, one thousands, hundreds, tens, ones, decimal points, tenths, hundredths, thousandths, ten thousandths , hundred thousandths

Between ones and tenth values ​​separated by commas (decimal points)

Decimal numbers can also be expressed as proper or mixed fractions

The position of each digit in decimal numbers is important.

Because the decimal number is based on the number 10, As we move left, each position is 10 times bigger, and As we move right, each position is 10 times smaller

On the left of the decimal point is a whole number

"Equivalent to" mean having the same value.

In the decimal addition operation, we must pay attention to the place value

Addition between decimal numbers must be the same place value, for example between hundreds with hundreds, ten with ten and so on

Or if we use a vertical addition system, one under the other, pay attention to the decimal point, must be straight from top to bottom

In this addition operation we check the results of the addition of each decimal number operation

3.7−6.4 = - 2.7

a. 6.4 + 3.7 = 10.1

b. 6.4 - 3.7 = 2.7

c. -6.4 + 3.7 = -2.7

d. - 6.4 - 3.7 = -10.1

Answer choices that have the same result is option C

Or simply this is the commutative form of addition operations

a + b = b + a (a = -6.4, b=3.7)

-6.4+3.7 = 3.7 +(-6.4)

-6.4+3.7 = 3.7 - 6.4

Explanation:

The associative property is defined as a grouping of multiplication, addition, subtraction and division.

[tex]\boxed{a + \left( {b + c} \right) = \left( {a + b} \right) + c}[/tex]

In commutative property we interchange the numbers or digits.

This property can be used for multiplication and addition. It cannot be used in division and subtraction.

Commutative property for addition is [tex]\boxed{x + y = y + x}[/tex]

The expression is [tex]3.7 - 6.4.[/tex]

[tex]A = 3.7 - 6.4[/tex]

By commutative property of addition the expression can also be expressed as follows,

Answer:

$1797914.419

Step-by-step explanation:

Given : Revenue in 2000 for a bakery chain totaled $10 billion from 5,562 shops nationwide

To Find:What was the average revenue in 2000 per shop?

Solution:

Revenue in 2000 for a bakery chain totaled $10 billion from 5,562 shops

So, the average revenue in 2000 per shop =[tex]\frac{10000000000}{5562}[/tex]

                                                                         =[tex]1797914.419[/tex]

Hence the average revenue in 2000 per shop was $1797914.419

Answer: The point slope form of the equation for this line is given by

[tex]y-8=-(x+3)[/tex]

Step-by-step explanation:

Since we have given that

The slope intercept form of the equation of a line is given by

[tex]y=-x+6-------------------(1)[/tex]

Line passing through a point is given by

(-3,8)

So, from the equation (1), we get that

m = Slope of line = -1

So, Point slope form of the equation of the line is given by

[tex]y-y_0=m(x-x_0)\\\\(y-8)=-1(x+3)\\\\y-8=-(x+3)[/tex]

Hence, the point slope form of the equation for this line is given by

[tex]y-8=-(x+3)[/tex]

The requried, at the beginning of May (the fifth month), the niece will have $162 in her account.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

In the first month, the niece has $1 in her account.

In the second month, she triples that amount to have $3, and Mr. Howard doubles it to $6.

In the third month, she triples $3 to have $9, and Mr. Howard doubles it to $18.

In the fourth month, she triples $9 to have $27, and Mr. Howard doubles it to $54.

So at the beginning of May (the fifth month), the niece will have 54×3 = $162 in her account.
