Answer:
1.4650 (the first option in the list of possible answers)
Step-by-step explanation:
Start by isolating the exponential expression on one side of the equal sign, thus subtracting 2 from both sides:
Now, in order to solve for "x", we need to lower the exponent, and for that purpose we use logarithm base "3":
In order to find this logarithm, we use the change of base formula:
which rounded to four decimals gives: 1.4650
Answer:
x = 6
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 6 from both sides.
(6x)/6 = (36)/6
x = 36/6
x = 6
x = 6 is your answer.

Answer:
210 minutes
Step-by-step explanation:
First, we want to find out how many meters cubed of water there is, which is the volume.
The volume of this prism would be, the average of the two sides multiplied by 2 and 1.
1.5+0.6 = 2.1
2.1/2 = 1.05
1.05*2=2.1
2.1*1=2.1
2.1 meters is the volume but because it goes down by 30 cm, we have to convert 2.1 to cm.
2.1 * 100 = 210 cm.
Every 30 minutes, it goes down by 30 cm so:
210/30 = 7
210 minutes until it's empty
