Find 4.5×10^7 over 1.5×10^-8 . write answer in scientific notation.

Sati [7]

Answer:

$\large\boxed{\dfrac{4.5\times10^7}{1.5\times10^{-8}}=3\times10^{15}}$

Step-by-step explanation:

The scientific notation:

$a\times10^k\ \text{where}\ 1\leq a$

We have:

$\dfrac{4.5\times10^7}{1.5\times10^{-8}}=\dfrac{4.5}{1.5}\times\dfrac{10^7}{10^{-8}}$

Use

$\dfrac{a^n}{a^m}=a^{n-m}$

$=3\times10^{7-(-8)}=3\times10^{7+8}=3\times10^{15}$

Answer:

area of shaded portion of figure = 76.24 cm²

Step-by-step explanation:

find the area of the circle, a 60° segment of the circle, and an equilateral triangle with sides of 5 cm:

area of circle = πr² = (3.14)(5²) = 78.5 cm²

area of 60° segment of circle = 78.5/6 = 13.08 cm²

area of triangle = 1/2(4.33)(5) = 10.82 cm²

The shaded area will be:

full circle area - (60° segment - triangle) = 78.5 - 13.08 + 10.82 = 76.24 cm²
