Your answer should be 1.7
I hope this helps! Good Luck!
Answer:
it represents 10 stars in the galaxies
Step-by-step explanation:
10 to the power of 12 would be 1,000,000,000,000, 10 to the power of 11 would be 100,000,000,000, and those two number divided equals simply 10.
Answer:
0.67 / 100 : 31^3 : 31^3 / 25cm^3
x 10
0.67 / 100 = 67 / 10000000 grams/cm : 29791 / 15625 / 29791
149253.731 : 0.52
divide by 1000
= 149.253731
= 149.3 kg
Ratio kg = 149.3 : 0.5
Step-by-step explanation:
Mole Ratio
The mole ratio compares the number of moles in a balanced equation.
This is the comparison between the coefficients in front of the chemical formulas.
If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species.
Mole ratios are used to predict how much product a reaction forms or to determine how much reactant is needed to make a set amount of product.
Mole Ratio Units
Mole ratio units are either mole:mole or else it is a dimensionless number because the units cancel out. For example, it's fine to say a ratio of 3 moles of O2 to 1 mole of H2 is 3:1 or 3 mol O2: 1 mol H2.
The answer is 40 because you just have to calculate the absolute value

Answer:
1) (x-6)^2=49
2) C
Step-by-step explanation:
Subtract 12 x and you get
-x^2-12x+13=0
You will be left with, after making a perfect square
(x-6)^2=49
To get rid of the squared/2nd power, add plus or minus to the opposite side and square root both sides. You will be left with
x-6=plus or minus 7
Your answer comes out to the to problem. Setting both to 0, you get -13, and 1. -6 plus 7 is 1, and -6 plus a -7 is -13.
