If No Digit Appears More Than Once, How Many 2-Digit Numbers Can Be Formed From The Digits 2, 3, 4, 6, And 7?? How Did You Receive Your Answer??

Answer:

$5865.6 per capita.

Step-by-step explanation:

That is $1465,2 billion divided by 249,793,675

= 1,465,200,000,000 /  249,793,675

=  $5865.6 per capita.

Answer:

Step-by-step explanation:

13/28 = 195/420

17/30 =  238/420

So that means that 3 17/30 > 3 13/28

Answer:

2.6 * bacteria

Step-by-step explanation:

We know that there are 20 million bacteria in 1 of coral reef. Let's write the number of bacteria in scientific notation with powers of 10:

Now let's write 1 in square meters, knowing that one cm equal 0.01 meter ( meters:

So now we can find how many bacteria there is in one of coral reef:

Number of bacteria in bacteria

we can now express 13000 in knowing that 1 km = 1000 m = m:

Since we know the number of bacteria per every of coral reef, the number of bacteria in of coral reef will be the product of these two numbers:

Total number of bacteria:

The conversion of the decimal number 0.63 into a fraction number will be 63 / 100.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of a numerator and a denominator.

The decimal number is 0.63.

Convert the decimal number into the fraction number.

⇒ 0.63

⇒ 0.63 x 100 / 100

⇒ 63 / 100

The conversion of the decimal number 0.63 into a fraction number will be 63 / 100.

The number halfway between 27 times 38 and 33 times 38 is 1140.

What is equation modelling? What is a mathematical equation and expression?

• Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

• A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.

• A mathematical equation is used to equate two expressions.

Given is 27 times 38 and 33 times 38.

Let the number be [x]. Then -

[x] = 1/2 x {(27 x 38) + (33 x 38)}

[x] = 1/2 x {38 x 60}

[x] = 19 x 60

[x] = 1140

Therefore, the number halfway between 27 times 38 and 33 times 38 is 1140.
