Convert 3,200,000 to a scientific notation.

3.2 x 10.6

6 is an exponent

Step-by-step explanation:

Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b

Step 1: To find a, take the number and move a decimal place to the right one position.

-Original Number: 3,200,000

-New Number: 3.200000

Step 2:  Now, to find b, count how many places to the right of the decimal.

-There are 6 places to the right of the decimal place.

Step 3: Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

-a = 3.2

-b = 6

Now the whole thing:

-3.2 x 10.6

step 4: Check your work,

10x6 = 1,000,000 x 3.2 = 3,200,000

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
