Answer:

$0.83

Step-by-step explanation:

$4 = 48x (x = number of text messages)

$4 ÷ 48 = x (divide by 48 on both sides)

0.83 = x

What areC12, C31, and C22 of matrix C?

Liono4ka [1.6K]

Compute the sum to simplify C :

$C = \begin{bmatrix}16-0.5 & 9+0 \\ -3+5 & 0 + 8 \\ 4-3 & -10+14\end{bmatrix} = \begin{bmatrix}15.5 & 9 \\ 2 & 8 \\ 1 & 4\end{bmatrix}$

Now, $c_{ij}$ is the entry of the matrix in row i and column j, so

$C = \begin{bmatrix}15.5 & \boxed{9} \\ 2 & 8 \\ 1 & 4\end{bmatrix} \implies c_{12} = 9$

$C = \begin{bmatrix}15.5 & 9 \\ 2 & 8 \\ \boxed{1} & 4\end{bmatrix} \implies c_{31} = 1$

$C = \begin{bmatrix}15.5 & 9 \\ 2 & \boxed{8} \\ 1 & 4\end{bmatrix} \implies c_{22} = 8$

SV−→bisects ∠RST. If m∠RSV = 64, what is m∠RST?

Anuta_ua [19.1K]

Given:

$\overrightarrow{SV}$ bisects ∠RST.

$m\angle RSV=64^\circ$

To find:

The $m\angle RST$ .

Solution:

Since, $\overrightarrow{SV}$ bisects ∠RST, therefore

$m\angle RSV=m\angle VST$ ...(1)

Now,

$m\angle RST=m\angle RSV+m\angle VST$

$m\angle RST=m\angle RSV+m\angle RSV$ [Using (1)]

$m\angle RST=2\times m\angle RSV$

$m\angle RST=2\times 64^\circ$ $[\text{Given }m\angle RSV=64^\circ]$

$m\angle RST=128^\circ$

Therefore, the value of $m\angle RST$ is $128^\circ$ .
