Answer:1.5 hours
Step-by-step explanation:
$8.50 is for 1/2 hour
In $25.50, the can use for (25.5*.5)/8.5 = 1.5 hours
Answer:
We want to divide 30 by it's half.
The half of 30 is 30/2 = 15
then we have: 30/15 = 2
Now we want to add the half of 18, that has ben divided by the half of the half of 12 hafter been divided by half.
The half of 12 is 12/2 = 6
the half of the half of 12 is 6/2 = 3
now, we wanto to divide the half of 18 by that number.
The half of 18 is 18/2 = 9
then we have 9/3 = 3
and we wanted to add this to the number previous found:
2 + 3 = 5
Answer:
Relative Size, S, is 1584.89
Step-by-step explanation:
The equation is 
Where,
- R is the measurement in Richter Scale
- S is the relative size of the earthquare
<u>It is given that in Richter Scale, an earthquake measured 3.2, so
.</u>
<em>They want to know relative size, S, so we put given information in equation and solve for S:</em>

<em>Converting to exponential form, we have:</em>

<em>Rounding to nearest hundredth, we have:</em>
