Water covers about 1.385 x 108 square miles of Earth's surface. How is this number written in standard notation?

1.4958 x 10^2

Step-by-step explanation:

The product of the multiplication is 149.58. The formula for standard notation is: A x 10^n, where 1<=A<10.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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
