64 rounded to the nearest tenth is 60
Problem A
When you use the term larger, you mean that (if the power is positive) the bigger number is in the numerator. 4*10^15 > 8 * 10^9 So 8 * 10^9 is in the denominator
Solution
![\dfrac{4*10^{15}}{8*10^9} =0.5*10^6 =0.5*10^1*10^5=5*10^5](https://tex.z-dn.net/?f=%5Cdfrac%7B4%2A10%5E%7B15%7D%7D%7B8%2A10%5E9%7D%20%3D0.5%2A10%5E6%20%3D0.5%2A10%5E1%2A10%5E5%3D5%2A10%5E5)
Note:The tricky part is recognizing what to do with the 0.5 * 10^6. You can always break apart a power into it's parts. Since 6 = 5 + 1, the power can be broken down into 10^1*10^5. The 10^1 is used to get the 0.5 to a number that is a single digit.
Problem 2
I'm just going to give you the answer to this. Please use Problem A as a guide.
![\dfrac{2*10^-5}{4*10^-12} = \dfrac{0.5*10^{-5}*10^{12}}{1} = 5*10^6](https://tex.z-dn.net/?f=%5Cdfrac%7B2%2A10%5E-5%7D%7B4%2A10%5E-12%7D%20%3D%20%5Cdfrac%7B0.5%2A10%5E%7B-5%7D%2A10%5E%7B12%7D%7D%7B1%7D%20%3D%205%2A10%5E6)
Answer:
98.518 repeating prercent
Step-by-step explanation:
2 out of 135 can also be written as 2/135
2 divided by 135 is 0.014814814814
that number is the percentage of failures
100% in decimal form is 1.00
1.00 subtracted by the percentage of failures is the percentage of successes
which is .98518518518, 518 repeating move the decimal over 2 and you got the percentage 98.518 repeating
Label equation 1 and equation 2,
Then 4y can be cancelled down from both, so we would do equation 1 plus equation 2,
Once you did equation 1 plus equation 2 you should have :
6x=-8
So X= -4/3
Then we would sub x into equation 2,
So it would be, 4/3+4y= -2
Y=-5/6
So final answer is
X = -4/3 Y= -5/6
Answer:
Step-by-step explanation:
7 x 5 = 35
35/2 = 17.5
