Volume of the can = 300
Option D: 3.47*10^-7 is the correct answer
Step-by-step explanation:
In order to determine the number written in standard scientific notation, first of all we have to understand how the scientific numbers are written
the scientific numbers are written in the form of:
Here
a is a number between 1 and 10 while the value of n can be only integer (positive or negative)
so,
In the given options:
Option A has a number larger than 10 in place of a so it is not in standard notation
Option B has a number less than 1 in place of a so it is also not in standard notation
Option C has a number larger than 10 in place of a so it is not in standard notation
Option D is in standard scientific notation as 1<3.47<10 and the power of 10 is integer
Hence,
Option D: 3.47*10^-7 is the correct answer

Answer:
the cost of filling the pool is $386.3
Step-by-step explanation:
Given;
dimension of the rectangular pool, = 25 yd by 30 yd by 5.1 ft
covert the given dimensions to feet;
1 yd = 3 ft
25 yd = 25 x 3 ft = 75 ft
30 yd = 30 x 3 ft = 90 ft
The volume of the rectangular pool in cubic feet (ft³);
Volume = 75 ft x 90 ft x 5.1 ft
Volume = 34,425 ft³
Convert the volume to gallons;
1 ft³ = 7.481 gallons
10,125 ft³ = 34,425 x 7.481 gallons
= 257,533.425 gallons
The cost per a 1000 gallons is $1.50, then cost of the 257,533.425 gallons is calculated as;
Therefore, the cost of filling the pool is $386.3
