2 in.
Find the surface
area of this figure.
2 in.
8 in.
[?] square inches
8 in.
5 in.
12 in.
10 in.
Answer:
528
Step-by-step explanation:
Surface area of bottom block + Surface area of top block - 2(Shared surface area)
Bottom block: 2(10*12) + 2(5*12) + 2(5*10) = 240 + 120 + 100 = 460 square inches
Top block: 2(2*2) + 4(2*8) = 8 + 64 = 72 square inches
Shared surface area = 2*2 = 4 square inches
Plugging into our formula:
460 + 72 - 4 = 528 square inches

Marta told Maribel “The sum of fifty and half the number of oranges is the same as one-hundred-twenty.” Maribel wrote 50 (one-half) + m = 120 What is her error?
Answer:
Her error was that the half should have been multiplied by m, instead
[tex]50 + \frac{1}{2}m = 120[/tex]
Step-by-step explanation:
Given
[tex]Base\ Amount = 50[/tex]
[tex]Rate = 0.05[/tex]
[tex]Days = n[/tex]
So, we have:
[tex]Base\ Amount + Rate * days = 120[/tex]
[tex]50 + \frac{1}{2}m = 120[/tex]
Hence, the error in her workings is that she should have pre-inform her before God and man.
Answer:
C - The One-half should be multiplied by m.

Answer:
X is 160 degrees
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
Answer:
X=160° because straight line =180
180°-20
160°
Solve the matrix equation for X:
Multiply on the right by the transpose of the matrix on the left side:
[tex]X\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}=\begin{bmatrix}-5&-1&0\\5&-2&5\end{bmatrix}[/tex]
[tex]X\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}^\top=\begin{bmatrix}-5&-1&0\\5&-2&5\end{bmatrix}\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}^\top[/tex]
The transpose is just the same matrix with the entries reflected along the main diagonal:
[tex]\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}^\top=\begin{bmatrix}1&3\\-1&0\\2&1\end{bmatrix}[/tex]
So
[tex]X\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}\begin{bmatrix}1&3\\-1&0\\2&1\end{bmatrix}=\begin{bmatrix}-5&-1&0\\5&-2&5\end{bmatrix}\begin{bmatrix}1&3\\-1&0\\2&1\end{bmatrix}[/tex]
[tex]X\begin{bmatrix}6&5\\5&10\end{bmatrix}=\begin{bmatrix}-4&-15\\17&20\end{bmatrix}[/tex]
Now multiply on the right by the inverse of the matrix on the left side:
[tex]X\begin{bmatrix}6&5\\5&10\end{bmatrix}\begin{bmatrix}6&5\\5&10\end{bmatrix}^{-1}=\begin{bmatrix}-4&-15\\17&20\end{bmatrix}\begin{bmatrix}6&5\\5&10\end{bmatrix}^{-1}[/tex]
[tex]X=\begin{bmatrix}-4&-15\\17&20\end{bmatrix}\begin{bmatrix}6&5\\5&10\end{bmatrix}^{-1}[/tex]
The inverse is
[tex]\begin{bmatrix}6&5\\5&10\end{bmatrix}^{-1}=\frac1{60-25}\begin{bmatrix}10&-5\\-5&6\end{bmatrix}=\begin{bmatrix}2/7&-1/7\\-1/7&6/35\end{bmatrix}[/tex]
So
[tex]X=\begin{bmatrix}-4&-15\\17&20\end{bmatrix}\begin{bmatrix}2/7&-1/7\\-1/7&6/35\end{bmatrix}=\boxed{\begin{bmatrix}1&-2\\2&1\end{bmatrix}}[/tex]
