What is 1/144 as an expression using a negative exponent

MrRissso [65]

ANSWER

${12}^{ - 2}$

EXPLANATION

The given expression is

$\frac{1}{144}$

This is the same as:

$\frac{1}{12 \times 12}$

In index notation, we write this as

$\frac{1}{ {12}^{2} }$

To write this as a negative index, we use the property:

$\frac{1}{ {a}^{m} } = {a}^{- m}$

This implies that;

$\frac{1}{ {12}^{2} } = {12}^{ - 2}$

12 yo<br> 5 yd<br> what is the length of the hypotenuse

Allushta [10]

I'm sure that the hypotenuse is 13 yards

Here's the formula used:

Length of Hypotenuse² = Length of side 1² + Length of side 2²

So here's how to solve this question:

12 squared + 5 squared = hypotenuse

(Then square the values)

144 + 25 = 169

Divide 169 by the square root to get the length of the hypotenuse: 13

Hope this helps!

the volume of solid A is 28m3 and the volume of solid B is 1,792m3. If the solids are similar, what is the ratio of the surface

Maslowich

If k is the scale factor between the dimensions of the similar solids, the areas are related by k² and the volumes are related by k³. That is
$\ \ \dfrac{V_{a}}{V_{b}}=k^{3}$
$\ \ k=(\dfrac{V_{a}}{V_{b}})^{\frac{1}{3}}$

The areas are related by k², so
$\ \ \dfrac{A_{a}}{A_{b}}=k^{2} = (\dfrac{V_{a}}{V_{b}})^{\frac{2}{3}}$
$\ \ \dfrac{A_{a}}{A_{b}} = (\dfrac{28\ m^{3}}{1792\ m^{3}})^{\frac{2}{3}}=(4^{-3})^{\frac{2}{3}}$
$\ \ =4^{-2}=\dfrac{1}{16}$

The ratio of the surface area of solid A to that of solid B is ...
1/16
