Write (8a-^3) -2/3 in simplest form

Anna71 [15]

$(8a^{-3})^{\frac{-2}{3}} = \frac{a^2}{4}$

<em><u>Solution:</u></em>

<em><u>Given that,</u></em>

$(8a^{-3})^{\frac{-2}{3}$

We have to write in simplest form

<em><u>Use the following law of exponent</u></em>

$(a^m)^n = a^{mn}$

Using this, simplify the given expression

$(8a^{-3})^{\frac{-2}{3}} = 8^{\frac{-2}{3}} \times a^{ -3 \times \frac{-2}{3}}\\\\Simplifying\ we\ get\\\\(8a^{-3})^{\frac{-2}{3}} = 8^{\frac{-2}{3}} \times a^2\\\\We\ know\ that\ 8 = 2^3\\\\Therefore\\\\(8a^{-3})^{\frac{-2}{3}} =2^3^{\frac{-2}{3}} \times a^2\\\\(8a^{-3})^{\frac{-2}{3}} =2^{-2} \times a^2\\\\(8a^{-3})^{\frac{-2}{3}} = \frac{a^2}{4}$

Thus the given expression is simplified

Vince has a movie rental gift card that start with $50 on it. Each movie he rents costs him $4.

Leto [7]

Linear function: d = -4m+50 (that's a negative 4 btw)

Slope: -4

y-intercept: 50

I'm truly sorry but I forgot how to do the last one :(

Gabrielle's age is two times Mikhail's age. The sum of their ages is 81. What is Mikhail's age?

Darya [45]

Answer:

27

Step-by-step explanation:

Let <em>g </em>be Gabrielle's age and <em>m </em>be Mikhail's age.

We can turn the statements the problem gives us into mathematical expressions to help us solve.

Gabrielle's age is two times Mikhail's age:

<em>g </em>= 2<em>m</em>

The sum of their ages is 81:

<em>g </em>+ <em>m </em>= 81

This gives us a system of equations that will allow us to solve for Gabrielle's age.

<em>g </em>+ <em>m </em>= 81

(2<em>m</em>)<em> </em>+ <em>m </em>= 81

3<em>m </em>= 81

<em>m</em> = $\frac{81}{3}$

<em>m </em>= 27

If we need to solve for Gabrielle's age, we can do the following.

<em>g </em>= 2<em>m</em>

2(27)<em> </em>= <em>g</em>

54 = <em>g</em>

g = 54

Mikhail's age is 27.

Gabrielle's age is 54.

Please help me solve

Answer:

x = 36.3°

using tane rule:

$\sf tan(x)= \dfrac{opposite}{adjacent}$

Here!

x = missing angle

opposite = 22

adjacent = 30

=============

$\hookrightarrow \sf tan(x) = \dfrac{22}{30}$

$\hookrightarrow \sf x= tan^{-1}(\dfrac{22}{30} )$

$\hookrightarrow \sf x= 36.253^{\circ \:}$

$\hookrightarrow \sf x= 36.3^{\circ \:}$ ( rounded to nearest tenth of a degree)
