Answer:
y = 52 - 8x
Step-by-step explanation:
If he painted for 3 hours at a rate of 8 square meters per hour, the area painted was:
If after 24 squared meters painted, there are still 28 left, the total area is:
The area still left to paint is initially 52 squared meters and decreases at a rate of 8 square meters per hour, the function that describes the relationship between the area left to paint (y) and number of hours (x) is:
y = 52 - 8x
Answer:
Step-by-step explanation:
Given
--- big circle
--- area of small circle
Required
Probability that a point selected lands on the small circle
Calculate the area of the big circle using;
Where
So, we have:
This gives:
The probability that a point selected lands on the small circle is calculated by dividing the area of the small cicle by the big circle
This gives:
Simplify
