Answer:
A
Step-by-step explanation:
Cause it right and pls dont remind me
9 inches long
9 divided by 10 is .9
multiply it by 10 (to get the length of the purple ribbon) and the answer is 9
The square root of 729 is in fact 27, as it is a perfect square, but this is not well known, so we can figure it out like this:
What goes into 729 that are perfect squares? 81 and 9:
Take the square root of 81 (9) and the square root of 9 (3). Move these to the outside of the square root (they will multiply with 3 since 3 is multiplied to the square root in the original problem)
Now, just multiply:
Answer:
1.837 X 10^9 is 5103 times greater than 3.6x10^5
Step-by-step explanation:
1.837 X 10^9 =
Calculate the value
Solution
1,837,000,000
3.6x10^5
Evaluate the power
3.6 x 100,000
Multiply the numbers
360,000
Solution
360,000
Divide
1,837,000,000 / 360,000
Solution
5102.77778
Round
5103
1,837,000,000 > 360,000
Each one is multiplied by -2...
PROOF
-5 * 10 = -20
-20 * -2 = 40
And so on.
So we need two more numbers so do 40 * -2...
40 * -2 = -80
And then...
-80 * -2 = 160
So the first 6 numbers are...
-5, 10, -20, 40, -80, 160.
We need to find the SUM, which is all the numbers added together.
-5 + 10 - 20 + 40 - 80 + 160 = 105
105 is your answer.
