Volume of a Cube Formula: V = a³

  • <em>a</em> is any side length

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>a</em> = 5 cm

<u>Step 2: Find Volume</u>

  1. Substitute in variables [Volume of a Cube Formula]:                                    V = (5 cm)³
  2. Evaluate exponents:                                                                                         V = 125 cm³

A building that is 100 for tall casts a shadow that makes a 30 degree angle. Approximately how long in feet is the shadow across
skad [1K]

Answer:   173.20 ft

Step-by-step explanation:

Observe the attached image. To know how long the shadow is, we must find the length of the adjacent side in the triangle shown. Where the opposite side represents the height of the building

By definition, the function tan (x) is defined as

tan(x) = \frac{opposite}{adjacent}

So

opposite = 100\ feet\\x=30\°

adjacent = l

Then

tan(30\°) = \frac{100}{l}

l = \frac{100}{tan(30\°)}

l = 173.20\ ft

Plzzzzzzzz! A suitcase lock has a code 4 symbols long. The symbols on the lock are a star, a square, a circle, a triangle, a lin
34kurt

Answer:

                \dfrac{1}{30}

Step-by-step explanation:

6 symbols and 4-symbol code so number of combinations wich doesn't contain the same symbol twice would be:

6•5•4•3 = 360

If code starts with a star followed by triangle that means only one posibility for first two symbols and code doesn't containing the same symbol twice means that left 4 symbols for next two.

So number of combinations of code starting with a star followed by triangle and doesn't containing the same symbol twice will be:

1•1•4•3 = 12

The probability that a randomly chosen code starts with a star followed by triangle and doesn't contain the same symbol twice:

\dfrac{1\cdot1\cdot4\cdot3}{6\cdot5\cdot4\cdot3}=\dfrac{1\cdot1}{6\cdot5}=\dfrac{1}{30}

I just need the answer bru why’s it gotta Make write 20 words‍♂️ this is dumb as hell bru‍♂️
TiliK225 [7]

Answer:

11

Step-by-step explanation:

W^7/W^-2=W^7+2=W^9 ( when divide subtract the exponent (7-(-2))

W^?/W² = W^?-2

W^9=W^(?-2)

9=?-2

?=11

W^7/W^-2 = W^11/W²
