Answer:

The formula of a Pythagorean Theorem is a^2 + b^2 = c^2

The length of c is 5 inches.

Step-by-step explanation:

a^2+b^2=c^2

3^2+4^2=c^2

25=c^2

Square root of 25= square root of c^2

5=c

Note that "^" means the number to the specified number.

Ex: 2^3

2 to the third power

2 cubed

Hope this helps!!!

A typical sugar cube has an edge length of 1.00 cm. Imagine you have a cubical box that contains a mole of sugar cubes, perfectl

alisha [4.7K]

Answer:

844368.7 m

Step-by-step explanation:

We are given that a typical sugar cube has an edge length of 1.00 cm.

We have to find the edge length of the box in meters.

Edge length of sugar cube=1 cm = $10^{-2}m$ ( $1 cm=\frac{1}{100}m$ )

Volume of a sugar cube= $side\times side\time side=(10^{-2})^3=10^{-6}m^3$

1 mole of sugar= $6.02\times 10^{23}units$

Volume of 1 unit= $10^{-6} m^3$

Volume of $6.02\times 10^{23}$ units= $6.02\times10^{23}\times 10^{-6}=6.02\times 10^{17} m^3$

Volume of box=1 mole of sugar= $6.02\times 10^{17} m^3$

Edge length of box= $\sqrt[3]{6.02\times 10^{17}}=844368.7 m$

Answer:

$-\frac{1}{2}$

Step-by-step explanation:

$-\frac{5}{6} +\frac{6}{18}$

$-\frac{5}{6} +\frac{2}{6}$ reduced

$\frac{-5+2}{6}$ transformed the expression to make it easier

$-\frac{3}{6}$ add

$-\frac{1}{2}$ reduce

Evaluate the following if k=0.5, n=-3, and p=-2: K+n(p^2)

ivann1987 [24]

Answer:

-11.5

Step-by-step explanation:

$K + n( {p}^{2} ) \\ \\ plug \: K = 0.5, \: n = - 3, \: p = - 2 \\ \\ K + n( {p}^{2} ) \\ \\ = 0.5 + ( - 3) \{ {( - 2)}^{2} \} \\ \\ = 0.5 - 3 \{ 4 \} \\ \\ = 0.5 - 12 \\ \\ = - 11.5$
