-6.59 written as a fraction is _____

The fractional form of -6.59 will be -(659/100).

What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given that -6.59

Now multiply and divide by 100

⇒ (-6.59) × 100/100

⇒ (-6.59 × 100)/100

⇒ -659/100 which is a fraction number and cannot be divisible.

Hence "The fractional form of -6.59 will be -(659/100)".

-2(11-12x)=-4(1-6x whats the anwer

Solution

the negative signs first councel so that we remain with

2 (11-12x) = 4(1-6x)

22-24x = 4-24x

22-4. = 24x+24x

18. = 48x

18/48. = x

3/8. = x

the negative signs first councel so that we remain with

2 (11-12x) = 4(1-6x)

22-24x = 4-24x

22-4. = 24x+24x

18. = 48x

18/48. = x

3/8. = x

How many odd integers from 1000 through 9999 have distinct digits?

We know that

step 1

the number of elements in a list from n to m is (m-n)+1

therefore

from 1000 to 9999 there are

(9999-1000)+1 = 9000 elements

step 2

Since even and odd numbers alternate, half of our list is composed of odd numbers. Therefore, there are 4500 of them

step 3

To construct a 4 digit odd number, we have 5 choices for the last digit.

(1-3-5-7-9)

then

we have

8 choices for the first (not 0 or same as last digit),

8 choices for the second

7 choices for the third.

there are (8)(8)(7)(5) = 2240

the answer is 2240 odd numbers with distinct digits in the list

step 1

the number of elements in a list from n to m is (m-n)+1

park a covers an area of 4,926 square kilometers. it is 1,845 square kilometer larger than park b. park c is 4,006 square kilometers larger than park a. what is the area of all three parks?

Answer:

The total area of all three parks is 16,939 square kilometers.

Step-by-step explanation:

Park A is 1,845 square kilometer larger than park B. That means, park B is 1,845 square kilometer smaller than park A.

Given that, park A covers an area of 4,926 square kilometers.

So, the area of park B will be: square kilometers.

Now, park C is 4,006 square kilometers larger than park A. So, the area of park C will be: square kilometers.

Thus, the total area of all three parks will be: square kilometers.
