A mile is about 6 x 104 inches. An
average human hair is 3 x
10-3 inches
thick. About how many
times longer is a
mile than a human hair?

Step-by-step explanation:

Given parameters:

              1 mile = 6 x 10⁴ inches

Average human hair  = 3 x 10⁻³ inches

Unknown:

How many times longer is a mile than a human hair;

Solution:

 Since we know that a mile 6 x 10⁴ inches , we can compare this quantity to the human hair;

     Number of times  =

     Number of times  = 2 x 10⁴⁺³

     Number of times  = 2 x 10⁷

So, a mile is 2 x 10⁷ times longer than the human hair.

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
