0.0052 scientific notation

Answers

To put a number into scientific notation, we multiply or divide the number by 10 over and over until we have a number between 1 and 10. But we can't just change a number so we have to account for what we did by describing how many times we multiplied or divided with exponents.

Each time we multiply by 10 the decimal moves 1 place to the right. Each time we divide by 10 the decimal moves 1 place to the left. The exponent we use will describe the number of times we moved the decimal to the right or left. The exponent will be positive or negative to describe the direction we need to move the decimal to represent our original number.

I know... that sounds confusing, but it's really easy! Let's do yours...

Now we need to move the decimal to get a number between 1 and 10. So we move the decimal 3 places to the right to get 5.2

Now we have to describe how to get to the original number with the exponents. We moved the decimal 3 places right so to get our number back we would have to move it back 3 places to the left so negative exponent 3... Here's how we represent it..

5.2 x 10^-3

So what that says is if we take 5.2 and divide it by 10 three times,we will get our original number.

Answer:

5.2 x 10^-3

Step-by-step explanation:

Eighty percent of the tourists in a group took a bus and the rest took a taxi. The bus fare per person is 40% less than the taxi fare per person. All together they paid $68 for the tour transportation, and the bus fare per person is $3. How many tourists are in the group?

Answers

Answer:

Bus = 16 Tourists and Taxi = 4 Tourists

Total = 20 Tourists

Step-by-step explanation:

According to the Question,

Given, 80% of the tourists in a group took a bus and 20% took a taxi. Thus the Ratio of Tourists Travel by Bus toTaxi is 4x:1x.

The bus fare per person is 40% less than the taxi fare per person. And Also Given that the bus fare per person is $3 Thus, The Taxi fare per person would be $5.

All together they paid $68 for the tour transportation.

4x × 3 + x × 5 = 68
12x × 5x = 68
17x =68
x=4

And, the Ratio of Tourists Travels by Bus toTaxi is 4x:1x . So,the Tourists Travel by Bus to Taxi is 16 and 4 Respectively . Total = 20 Tourists are in the Group.
