Classify each number as rational or irrational. 1. 0.329 2. 127.5 3. -89 4. √ 101

A rational number is a number with a finite number of numbers after the decimal point, or the numbers after the decimal point repeat a given patern.

An irrational number is a number with infinite numbers afther the decimal point, and those numbers have no pattern, are all "random", some examples are the roots of prime numbers, like square root of 2.

1) 0.329

It has a finite quantity of numbers after the decimal point: rational

2) 127.5

It has a finite quantity of numbers after the decimal point: rational

3) -89

It has a finite quantity of numbers after the decimal point: rational

4)

101 is a prime number, so the square root of 101 must be a irrational number.

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )
