is the square root of 81 rational or irrational number and is 5 divided by 3.14 rational or irrational.

Answers

Answer 1

Answer: square root of 81 = 9 so it is rational number

5 divided by 3.14 = 5/3.14 = 500/314 so it is rational as well.

Answer 2

Answer: 5 divided by 3.14 = 1.5923566879 so it is irrational.

Solve 3/5=8/y. Round to the nearest tenth. 15.2 9.8 13.3 18.8

3/5 = 3/y
40 = 3y
Divide both by 3
Answer= 13.3

the sum of two numbers is 67. the smaller number is 3 less then the larger number. what are the two numbers?

thats the answer

x2 - 8x - 15

hope it helps

$Two\ numbers\ are\ x\ and\ x-3 \n x+x-3=67 \n 2x-3=67 \n 2x=70 \n x=35 \n \n 35\ and\ 35-3 \n \boxed{35\ and\ 32}$

the difference between two positive integers is 40. one integer is three times as great as the other. find the integer.

Be the integers: x and y

x - y = 40
x = 3y

Replace x in the first equation:

3y - y = 40
2y = 40
y = 20
x = 60

Find the length of the third side. If necessary, write in simplest radical form.

Answer:

$√(13)$

Step-by-step explanation:

let the 3rd side, the hypotenuse, be x

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 2² + 3² = 4 + 9 = 13 ( take square root of both sides )

x = $√(13)$

Answer:

Step-by-step explanation:

It is a right triangle and you have the measure of the cathets, we use the Pythagorean theorem

√(3² + 2²) =

√(9 + 4) =

√13
