Ethan's mistakes in sorting the shapes into two groups are:
- Shape C does not belong to group 1 because it does not have square corners
- Shape F does not belong to group 2 because it does not have any square corners
<h3>How to spot the mistakes?</h3>

- All the shapes in group 1 have 4 square corners
- All the shapes in group 2 have exactly 1 square corner

Answer:
r=7
Step-by-step explanation:
-84+15r=3r
Subtract 15r from each side
-84+15r-15r=3r-15r
-84 = -12r
Divide each side by -12
-84/-12 = -12r/-12
7 = r
Answer:
If the company produce and sell 'x' no. of thing-a-ma-bob , then
C(x) = $ (8809 + 2.05x)
R(x) = $ 4.92x
To make a profit the company must produce and sell at least 3070 thing-a-ma-bobs.
Step-by-step explanation:
If the company produces and sells "x" no. of thing-a-ma-bob, then,
the cost function is given by,
C(x) = $ (8809 + 2.05x) ------------------------(1)
The revenue function is given by,
R(x) = $ 4.92x -------------------------------------(2)
If C(x) = R(x), then,
4.92x = 8809 + 2.05x
⇒ 2.87x = 8809
⇒ x = 
⇒ x 
3069.34
So, to make a profit the company must produce and sell at least 3070 thing-a-ma-bobs.
