The answer is c.two or more transformations
Given :
Nathan smiled at 50 people one day and recorded that 36 people smiled back at him.
To Find :
How many people should Nathan expect to return a smile if he smiles at 650 people over a period of time.
Solution :
Ratio of people smiled by total number of people is :
Now, it is given that we have to use the given conditions.
Therefore, ratio will be same :
Therefore, number of smiles Nathan expect to return is 468.

Use PEMDAS
Answer:
- 20 + 8i
Step-by-step explanation:
Noting that i² = - 1
Given
[(6i + 9) + (4i - 5)] × 2i ← evaluate the terms inside the square bracket
= ( 6i + 9 + 4i - 5 ) × 2i
= (10i + 4) × 2i ← multiply each term in the parenthesis by 2i
= 20i² + 8i
= 20(- 1) + 8i
= - 20 + 8i
The equation that relates y, the amount of yellow paint in liters, and b, the amount of blue paint in liters, needed to make the Green Goober's special green paint is y + b = 888
<em><u>Solution:</u></em>
Given that the Green Goober mixes 333 liters of yellow paint with 555 liters of blue paint to make 888 liters of special green paint for his costume.
Let "y" be the amount of yellow paint in liters needed to make the Green Goober's special green paint
Let "b" be the amount of blue paint in liters needed to make the Green Goober's special green paint
<em><u>The required equation is:</u></em>
amount of yellow paint in liters + amount of blue paint in liters = Green Goober's special green paint
y + b = 888
Where y = 333 liters and b = 555 liters ( from given information)
Thus the equation is found
