What are the steps to solve this problem? 0.000027 divided 0.000009. explain how to use scientific notation?

1 answer:

6 0

Put it into standard form so you would have

27x10¯6 divided by 9x10¯6

Then you can divide the numbers so 27/9 = 3

Then to divide the powers you just take them away so - 6--6 = - 6 +6 = 0

Therefore the answer is just 3

Find the hypotenuse of a right triangle if side a=3 and side b=4

Slav-nsk [51]

Answer:

5 units

Step-by-step explanation:

By Pythagoras theorem:

$(hypotenuse)^2 = a^2+ b^2\\\therefore hypotenuse = \sqrt{a^2+ b^2} \\\therefore hypotenuse = \sqrt{3^2+ 4^2} \\\therefore hypotenuse = \sqrt{9+ 16} \\\therefore hypotenuse = \sqrt{25} \\\therefore hypotenuse = 5\: units$

5(n–2)=5n–10 What is the awnser

Leokris [45]

Answer:

Anything

Step-by-step explanation:

5n - 10 = 5n - 10

It doesn't matter what you put in for n, the equality can never be anything but an equality.

Suppose n = 10,000,000

Then 5*10,000,000 - 10 = 5*10,000,000

Step-by-step explanation:

It’s not A because the equation can not be any pair of numbers.

It’s not B because that is stupid logic.

It’s not C because (3,4) and (10,8) don’t work

It’s not F because there is 1 solution
