Answer:
<em>1 cm^2 : 9 m^2</em>
Step-by-step explanation:
The scale factor of an area is the square of the scale factor of a length.
The scale for lengths is 1 cm : 3 m.
You now square that scale to get the scale of the areas.
Scale of areas:
(1 cm)^2 : (3 m)^2
1 cm^2 : 9 m^2
I believe the formula is lxwxh if so it's 20 x 30 x 4= 2400 i hope this helped
Step-by-step explanation:
the slope is the ratio of "y coordinate difference / x coordinate difference".
so, let's find 2 good points (I mean by that with integer coordinates). I see e.g.
(-1, -1) and (0, -7)
x changes by +1 (from -1 to 0).
y changes by -6 (from -1 to -7).
so, the slope is -6/1 = -6.
D is the right answer.
Rectangle. if you simply graph the points, you are able to see the shape they form
There is a 50% probability.
First add up all of the sections to get a total.
10 Green + 15 Purple + 2 Blue + 3 Red = 30.
There are 15 purple out of 30.
15/30 = 1/2 probability, which is 50%.
