It is possible to convert a fraction to a decimal in mathematics. First, -3/11 is a fraction. To convert a fraction which is -3/11, divide 3 by 11 which you get .272727... and you get the idea. The '27' repeats. Therefore, the answer would be -.27 with a <span>Vinculum symbol which is a horizontal line above the number to indicate its repeating. Also, don't forget to put a negative sign!</span>

what power can you write to represent the volume of the cube shown? write the power as an expression with a base and an exponent
sergiy2304 [10]

Answer:

The power for the volume of the cube is '3'.

Exponent form of the volume is (\frac{1}{3})^3

Volume of the cube is \frac{1}{27} inch³.

Step-by-step explanation:

We are given,

A cube with side equal to \frac{1}{3} inches.

As we know,

Volume of a cube = side^{3}

Thus, we get,

Volume of the given cube is,

Volume = (\frac{1}{3})^3

i.e. Volume = \frac{1}{27} inch³

Thus, we have,

The power for the volume of the cube is '3'.

Exponent form of the volume is (\frac{1}{3})^3

Volume of the cube is \frac{1}{27} inch³.

Carrie and brent leave home at the same time. carrie drives due east at a rate of 30 mph, while brent drives due south at a rate
Helga [31]

<h3>They are 268 miles far apart after 4 hours</h3>

<h3>Further explanation</h3>

Acceleration is rate of change of velocity.

\large {\boxed {a = \frac{v - u}{t} } }

\large {\boxed {d = \frac{v + u}{2}~t } }

<em>a = acceleration ( m/s² )</em>

<em>v = final velocity ( m/s )</em>

<em>u = initial velocity ( m/s )</em>

<em>t = time taken ( s )</em>

<em>d = distance ( m )</em>

Let us now tackle the problem !

<u>Given :</u>

v₁ = 30 mph due east

v₂ = 60 mph due south

t = 4 hours

<u>Unknown :</u>

displacement = d = ?

<u>Solution :</u>

d_1 = v_1 \times t

d_1 = 30 ~ mph \times 4 ~ h

d_1 = \boxed {120 ~ miles}

d_2 = v_2 \times t

d_2 = 60 ~ mph \times 4 ~ h

d_2 = \boxed {240 ~ miles}

d^2 = (d_1)^2 + (d_2)^2

d^2 = 120^2 + 240^2

d^2 = 72000

d = \sqrt{72000}

d = 120\sqrt{5} ~ miles

d \approx \boxed {268 ~ miles}

<h2>Conclusion :</h2><h3>They are 268 miles far apart after 4 hours</h3>

Use the diagram below to answer the question.
Lunna [17]

Answer:

The length of shadow is 69 foot.

Step-by-step explanation:

We are given a shadow of lighthouse.

Length of top of lighthouse to end of shadow is 90 ft.

Angle make at top of lighthouse is 50°

Distance from foot of lighthouse to end of shadow is x ft.

we need to find the length of shadow i,e x ft

Using trigonometry ration:

\sin\theta=\dfrac{P}{H}

\sin50^\circ=\dfrac{x}{90}

x=90\times 0.766

x=68.94\approx 69\text{ ft}

Hence, The length of shadow is 69 foot.
