Approximately how many times greater is 6 x 10^-5 than 5 x 10^-9
8_murik_8 [283]

Answer: 6 \times 10^{-5} is 1.2 \times 10^4. times greater than 5 \times 10^{-9}.


Step-by-step explanation:

We are given two numbers.

First number  : 6 \times 10^{-5}.

Second number : 5 \times 10^{-9}.

In order to find how many times   6 \times 10^{-5} is greater than 5 \times 10^{-9}, we need to divide first number by second number.

Therefore,

6 \times 10^{-5} ÷ 5 \times 10^{-9}

or \frac{6 \times 10^{-5}}{5 \times 10^{-9}}

First we would divide 6 by 5.

On dividing 6 by 5, we get 1.2.

Now, we would divide 10^-5 by 10^-9.

In order to divide them, we can apply quotient rule of exponents \frac{a^m}{a^n} =a^{m-n}.

We get

\frac{10^{-5}}{10^{-9}}  = 10^{-5-(-9)} = 10^{-5+9} = 10^4.

Therefore,

\frac{6 \times 10^{-5}}{5 \times 10^{-9}} = 1.2 \times 10^4.

So, we could say finally 6 \times 10^{-5} is 1.2 \times 10^4. times greater than 5 \times 10^{-9}.

PLEASE HELP WITH MATH
lesantik [10]

Volume is length x width x height.

Calculate the volume of each rectangle and add them together.

7.5 x 7.5 x 3.55 = 199.6875

7.5 x 3.55 x 3.55 = 94.51875

Volume = 94.51875 + 199.6875 = 294.21 cubic meters

How do I find the area ?
zalisa [80]

Answer:

7.74 cm^2

Step-by-step explanation:

The  length of the side of the square is 3+3 = 6

The area of the square is

A =s^2 = 6^2 = 36

The area of the circle is

A = pi r^2  where the radius is 3

(3.14) 3^2 =28.26

Subtract the area of the circle from the area of the square to get the shaded area

36-28.26 = 7.74 cm^2
