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.
36/30=1.2
30/1.2=25
3x+4=25
3x=21
X=7
Therefore a is your answer

I calculated it logically
Fundamental principle of counting
The probability that the next customer that comes into Daniel's business will pay with a credit card is 23 / 87.
<h3>What is the probability?</h3>
Probability determines how likely it is that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that the next customer will pay with a credit card = number of people who paid with a credit card / total number of customers
23 / (23 + 60 + 4)
23 / 87
