When you write a number that is less than 1 in scientific notation how does the power of 10 differ from when you write a number greater than 1 in scientific notation?
Answer : In scientific notation all numbers are written in the form m × 10ⁿ. If the number is less than 1, ten is raised to a negative power, so : m × 10⁻ⁿ.
Example : a decimal number less than 1 is 0.02 = 2 x 10⁻² in scientific notation.
Hope this helps!
Answer:
sum of twice a number and three is 21
2x + 3 = 21
x = 9
First, we need to find the area of the rectangular playground.
To do this, we must multiply 40 by 10.
We get 400 meters².
Now divide 400 by 200 and you get 2.
That means 2 bags will be needed to cover the entire area of the playground.
To find the price, multiply 30 by 2.
The total cost for this project will be $60.
Hope this helped you out! :)
Yeah 1 pound is $4.80 so you'll have $0.20 left
