The table shows the values of different measurements in the metric system.
Lunna [17]

A micrometer has a power of 10^{-6}

A millimeter has a power of x 10^{-3}

A nanometer  has a power of 10^{-12}

A picometer  has a power of 10^{-12}

We are to write the numbers in standard form.

Standard form is a way of writing simplifying numbers and expressing numbers to a power of 10.

For example, to express 1000  in standard form, count the number of digits after the first number. There are 3 zeros. 3 would be the power of the number. So, 1000 in standard form is 1 x 10³

To express a decimal in standard form, count the numbers of zeros and the first non-zero digit  The negative of the number would be the power.

For example, 0.001 is standard form is 1 x 10^{-3}

A micrometer has 6 digits after the decimal point , it power would be x 10^{-6}

A millimeter has 3 digits after the decimal point, its power would be x 10^{-3}

A nanometer has 9 digits after the decimal point, its power would be x 10^{-12}

A picometer has 12 digits after the decimal point, its power would be x 10^{-12}

If Anthony has twice as nickels as one and one has 15 more nickels than Maria what is the value in dollars of Anthony's Nickels
worty [1.4K]

Answer:

Anthony has $2.10

Step-by-step explanation:

If Maria has 6 nickels and one has 15 more nickels than Maria, one has a total of 21 nickels. Since Anthony has twice the amount of nickels as One, you would multiply 21 by 2 to get a total of 42. It takes 20 nickels to make a dollar. If you divide 42 by 20 you get 2.1, which is equivaldnt to $2.10

Write each as a fraction or mixed number in lowest terms<br> 6.05 <br> 12.346<br> 7.5
AVprozaik [17]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the decimal number

6.05

Rewrite as

=6+0.05

=6+\frac{5}{100}        ∵ 0.05 = 5/100

=6+\frac{1}{20}

=\:\frac{121}{20}

=6\frac{1}{20}

Given the decimal number

12.346

Rewrite as

=12+0.346

=12+\frac{173}{500}              ∵ 0.346 = 346/1000 = 173/500

=12\frac{173}{500}

Given the decimal number

7.5

Rewrite as

=7+0.5

=7+\frac{1}{2}                 ∵ 0.5 = 1/2

=7\frac{1}{2}

Find the solution set of the inequality \qquad52- 3x &lt; -14.52−3x&lt;−14.
Anarel [89]

Answer:

Step-by-step explanation:

add 14.52 to both sides of the inequality to cancel that value out from the middle. Then you can divide both sides by 3x to get x by itself in the middle.
