Answer:

1) $\boxed{729}$

2) $\boxed{169}$

Step-by-step explanation:

1) 27²

<em>This means 27 is being multiplied 2 times.</em>

So,

=> 27*27

=> 729

2) 13²

<em>This means 13 is being multiplied 2 times</em>

So,

13*13

=> 169

What is 0.002 one tenth of.

jeka94

Let's say is "x".

so, "x" is the whole or 10/10 whilst 0.002 is 1/10 then, let's check

$\bf \begin{array}{ccll}
amount&fraction\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
0.002&\frac{1}{10}\\\\
x&\frac{10}{10}
\end{array}\implies \cfrac{0.002}{x}=\cfrac{\frac{1}{10}}{\frac{10}{10}}\implies \cfrac{0.002}{x}=\cfrac{\frac{1}{10}}{1}
\\\\\\
\cfrac{0.002}{x}=\cfrac{1}{10}\implies \cfrac{0.002\cdot 10}{1}=x$

At the moment a hot iron rod is plunged into freezing water, the difference between the rod's and the

jonny [76]

Answer:

<h2>The function is</h2><h2> $D(t) = 100 \times( \frac{40}{100} )^{t}$ </h2>

Step-by-step explanation:

At t = 0 the difference is 100 degree celsius.

After one second the temperature difference will be $100 - \frac{100\times60}{100}$ = $100(1 - \frac{60}{100} )$

After two second, the difference will be $100(1 - \frac{60}{100} )(1 - \frac{60}{100} ) = 100(1 - \frac{60}{100} )^{2}$

Hence, it can be written that,

$D(t) = 100 \times(1 - \frac{60}{100} )^{t}$ = $100 \times( \frac{40}{100} )^{t}$

The low temperatures for a week in winter were -2° F, -15° F, -7° F, 1° F, -4° F, 5° F, 8° F. What was the average low

Novay_Z [31]

Answer: -2 F

Step-by-step explanation:

To find the average, or <em>mean, </em>of a data set, you must first combine all of the values in the set. Since some of these values are negative, it seems more difficult to solve. But it isn't. To find the mean of any data sets, you can find the absolute value of each numerical value. If you combine these regularly, it would be -15, but that is incorrect. The answer is -2 because some of the values may be negative, but you can find the answer easily. Just remember: To find the mean of data sets with negative values, you can find their absolute values, and solve from there. If this does not work for you, then find another solution. But the correct answer is -2 F.
