Answer:

In 1942 , the U.S. Mint produced 154,500,000 nickels. The scientific notation of 154,500,000 is obtained as $1.545 \times 10^{8}$.

Step-by-step explanation:

  • In the problem, it is given that in 1942, the U.S. Mint produced 154,500,000 nickels.
  • It is required to write 154,500,000 in scientific notation.
  • To solve this first, move the decimal point so that the first factor is greater than or equal to 1 also it should be less than 10.
  • Count the number of decimal places n, and write the number as a product with a power of 10. Then check the answer.

Step 1 of 2

Obtain the scientific notation.

Here the original number, 154,500,000 is greater than 1 so we will have a positive power of 10 .

Move the decimal point to get 1.545, a number between 1 and 10 . Then we get,

1.54500000

The count of the number of decimal places the point was moved is 8 .

Write as a product with a positive power of 10 .

$1.545 \times 10^{8}$

Step 2 of 2

Check the answer.

Rewrite and simplify to check our answer.

$$\begin{gathered}1.545 \times 10^{8}=1.545 \times 100000000 \\=154500000\end{gathered}$$

For what values of x does the value of the fraction (3-x)/8 belong to the interval (−2; 5]?
Tamiku [17]

Answer:

-37\leq x\:

Step-by-step explanation:

To find the values of x for which, the value of \frac{3-x}{8} belongs to (-2,5],we solve the inequality;

-2\:

We multiply through by 8 to obtain;

-16\:

We subtract 3 to get

-19\:

Divide through by -1 to obtain;

19\:>x\ge-37

Or

-37\leq x\:
