<span>b.9 x 10^4 is 18 times larger than 5 x 10^3
This is a simple matter of floating point division. So let's do that.
9 x 10^4 / 5 x 10^3
First, divide the significands. Giving
9 / 5 = 1.8
And subtract the exponents
4 - 3 = 1
So the result of the division is
1.8 x 10^1 which is 18. So 9x10^4 is 18 times larger than 5x10^3. Now looking at the available options, it's obvious that only "b" is correct.</span>
Answer:
The average change in water level is: -3/4
Step-by-step explanation:
The average is calculated by adding up all the values and then dividing the sum by total number of values.
Given values are:
3/4, -9/4, -11/4, 5/4
The sum of values will be:
Total number of values is 4
So,
Hence,
The average change in water level is: -3/4
Answer:
3 1/5 = 16/5
4/16 = 1/4
simply and find a common denominator, in this case it is 20. Multiply the top and bottom by the same number, to get the bottom to twenty. So, to get 5 to 20, you must multiply by 4, so you have to multiply the top by 4 too, which is 64. Do the same for the next fraction.
16/5 = 64/ 20 (both x4)
1/4 = 5/20 (both x5)
now add
64/20 + 5/20 = 69/20
69/20 is the final answer because it cannot be simplified futher.
Answer:
21
Step-by-step explanation:
Total cloth length = 51 yards
Cloth requirement for each outfit = 2 2/5 = 12/5 yards
Total possible number of outfits can be calculated by dividing to total cloth length by the length of each outfit.
Total outfits = 51/ (12*5)
=> (51*5)/12
=> 21.25
As the number of suits is always an interger, so the total number of outfits made by 51 yards of clocth are 21
