A power company calculates a person's monthly bill from the number of

jenyasd209 [6]

Answer: (b)

Step-by-step explanation:

Given

Function for bill calculation is

$\Rightarrow b(x)=\left \{ {{0.15x\quad \quad \quad \, \ \ \ \ x200}} \right.$

The consumption is 700 kWh i.e. more than 200

Therefore, bill is given by the second function i.e. $0.10(x-200)+30$

Substitute 700 for x to get the bill

$\Rightarrow 0.1(700-200)+30\\\Rightarrow 50+30=\$80$

Hence, option (b) is correct.

Write the following numbers used in these statements in scientific notation. (Note: Some of these numbers have been rounded.)

VARVARA [1.3K]

Answer:

So 0.0000214 can be written as $2.14\times 10^{-9}cubic\ yard$

Step-by-step explanation:

We have given one cubic inch = 0.0000214 cubic yard

We have to convert this into scientific notation

We know that 0.0000214 can be written as $\frac{214}{10000000}$

We know that $\frac{1}{10}$ can be written as $10^{-1}$

So $\frac{1}{10000000}$ can be written as $10^{-7}$

So $\frac{214}{10000000}$ can be written as $214\times 10^{-7}=2.14\times 10^{-9}cubic\ yard$
