Answer: With exponents of 10, the exponent really just tells you how many zeroes there are behind the 1. So, for example, 10^4=10000 (4 zeroes behind 1). When multiplying decimals by exponents of 10, you move the decimal to the right, and the amount of places is the exponent number. For example, if I multiply 5.34 by 10^2, I move the decimal over to the right 2 times and get 534.

So, if you just multiply these you get 9.36*10000, which is 93600.

So, if you just multiply these you get 9.36*10000, which is 93600.

The driving distance from Alex's house to the museum is 6 7/10 miles. What is the round-trip distance?

Answer: The round trip distance is 6.7 miles.

Step-by-step explanation:

Since we have given that

Distance from Alex's house to the museum is

We need to find the round trip distance.

For which we first change the mixed fractions into improper fraction and then we divide it.

Driving distance from Alex's house to the museum is given by

So, the round trip distance is 6.7 miles.

Round trip is going there and back so it is 2*(6 7/10)=12 14/10=13 4/10=14 2/5
