Total amount of grey blocks is 55 so divide that by the amount of columns it’s being divided into. The answers 5.
10 large bags and 11 small bags because 10*9=90 and 156-90=66 and 6*11=66 so 90+66=156
When you want to find the slope of the perpendicular line, all you have to do is flip the known slope upside down and make it negative. You know that

slope is 3 and you know

is perpendicular. So, just flip 3 upside down into

and then make it negative,
-<span>

. If you look at the coordinate grid, you can see that

crosses the y-axis at 4. When you put those into slope-intercept form you get
= -</span>
x + 4.
Answer:
D) 112°
Step-by-step explanation:
Reflection is a type of transformation that require the turning of a point or an object about a reference point line.
In the given question, when the point is first reflected about l, it rotates at an angle of 56°. Then reflecting it about m give a total rotation of 112° by the point. Thus, the point (-4, 1) is rotated twice the angle between lines l and m.
