Answer:

A.

1.27

B.

Took what each block represented and added them together.

Step-by-step explanation:

The first block represents .89, and the second represents .38.

To add these, we just line them up and add as we usually would.

PLZZZZ HELLPP  50 POINTS TO WHO CAN ANSWER CORRECTLY
finlep [7]
For this case we are going to assume that Nina wrote:
 3/4 (1440) + 295.25 + (-33.50).
 The expression is correct since we have:
 ticket sales were three-fourths as much as yesterday. That means
 3/4 (1440)
 food sales were down by $ 33.50, that means:
 295.25 + (-33.50)
 Therefore, today's sales were:
 3/4 (1440) + 295.25 + (-33.50).
 answer
 Nina's expression is correct

42. Which matrix represents the image of the triangle with vertices at (-2,0), (1,5), and (4,-8) when dilated by a scale factor
jasenka [17]

The second matrix \left[\begin{array}{ccc}-6&3&12\\0&15&-24\end{array}\right] represents the triangle dilated by a scale factor of 3.

Step-by-step explanation:

Step 1:

To calculate the scale factor for any dilation, we divide the coordinates after dilation by the same coordinated before dilation.

The coordinates of a vertice are represented in the column of the matrix. Since there are three vertices, there are 2 rows with 3 columns. The order of the matrices is 2 × 3.

Step 2:

If we form a matrix with the vertices (-2,0), (1,5), and (4,-8), we get

\left[\begin{array}{ccc}-2&1&4\\0&5&-8\end{array}\right]

The scale factor is 3, so if we multiply the above matrix with 3 throughout, we will get the matrix that represents the vertices of the triangle after dilation.

Step 3:

The matrix that represents the triangle after dilation is given by

3\left[\begin{array}{ccc}-2&1&4\\0&5&-8\end{array}\right] = \left[\begin{array}{ccc}3(-2)&3(1)&3(4)\\3(0)&3(5)&3(-8)\end{array}\right] = \left[\begin{array}{ccc}-6&3&12\\0&15&-24\end{array}\right]

This is the second option.
