What is (½)3. ???????

Karolina [17]

It is hard to tell your precise intention. Choose the appropriate interpretation.

$\frac{1}{2} \times 3 = \frac{1 \times 3}{2} = \frac{3}{2} = 1\frac{1}{2}$

$(\frac{1}{2})^{3} = \frac{1^{3}}{2^{3}} = \frac{1}{8}$

ach light bulb at Hotel California is either incandescent or fluorescent. At a certain moment, forty percent of the incandescent

Trava [24]

Answer:

10%

Step-by-step explanation:

The computation of the percentage of bulbs that switched on incandescent is as follows;

Let us assume the incandescent be I

And, the fluorescent be F

Now the equation is

0.4I + 0.9F = 0.8 (I+F)

0.41I + 0.9F = 0.8I + 0.8F

So here

0.4I = 0.1F

Now the percentage would be for incandescent in the case of switched on is

= 0.4I ÷ 0.8(I+F) × 100

= 0.1F ÷ 1F

= 10%

Solve the following system of equations , and find the ordered pair. X =-y-6 and -7x +6y=-10

Blababa [14]

Given:

There are given the equation:

$\begin{gathered} x=-y-6...(1) \\ -7x+6y=-10...(2) \end{gathered}$

Explanation:

From the equation (1):

Put the value of x into the equation (2):

So,

From the equation (2):

$\begin{gathered} \begin{equation*} -7x+6y=-10 \end{equation*} \\ -7(-y-6)+6y=-10 \\ 7y+42+6y=-10 \\ 13y=-10-42 \\ 13y=-52 \\ y=-4 \end{gathered}$

Now,

Put the value of y into the equation (1):

So,

From the first equation:

$\begin{gathered} \begin{equation*} x=-y-6 \end{equation*} \\ x=-(-4)-6 \\ x=4-6 \\ x=-2 \end{gathered}$

Final answer:

Hence, the ordered pair of the solution is shown below:

$(-2,-4)$
