Answer:

Step-by-step explanation:

In order to prove congruency using SSS, we need to prove that all three pairs of sides are congruent.

We are already given that EF ≅ HI and that FG ≅ IJ.

Therefore, the last bit of information we need to prove congruency using SSS is that EG ≅ HJ.

Hence, our answer is C.

Hello There!

To find the quotient of $\frac{3}{4}$ ÷ $\frac{1}{8}$ ,

we need to multiply by the reciprocal meaning that the fraction

$\frac{3}{4}$ stays the same but we flip the numerator and

denominator for our second fraction so it will end up being

$\frac{8}{1}$ which is the same thing as 8 so the second choice

is your answer.

Please solve and show your work -3-2g=-12-5g please show work

Marta_Voda [28]

Answer:

$g = - 3$

Step-by-step explanation:

$- 3 - 2g = - 12 - 5g$

grouping like terms

 $- 2g + 5g = - 12 + 3$ 

 $3g = - 9$ 

dividing through by 3

 $\frac{3g}{g} = \frac{ - 9}{3}$ 

$g = - 3$

Answer:

The electron moved down to an energy level and has an energy of

$10.92 \times 10^{-19} \textsf{J}$

Step-by-step explanation:

$\textsf{initial energy level of electron}= 16.32 \times 10^{-19} \textsf{J}$

$\triangle E =\textsf{energy released}= 5.4 \times 10^{-19} \textsf{J}$

A positive energy change means that the electron absorbs energy, while a negative energy change implies a release of energy from the electron.

Therefore, when an electron absorbs energy, the electron moves up to higher energy levels, and when an electron releases energy, it moves to lower energy levels.

$\triangle E=E_2-E_1$

$\implies 5.4 \times 10^{-19} = 16.32 \times 10^{-19} -E_1$

$\implies E_1= 16.32 \times 10^{-19} -5.4 \times 10^{-19}$

$\implies E_1= 10.92 \times 10^{-19}$

Answer:

The electron moved down to an energy level and has an energy of

$10.92 \times 10^{-19} \textsf{J}$
