Answer:
a: 18pi
b: 3pi
Step-by-step explanation:
part a:
total area = 12^2*pi = 144pi
144pi/8 = 18pi
part b:
total circumference = 12*2*pi = 24pi
24pi/8 = 3pi
Answer:
No of white balls = 5
Step-by-step explanation:
Given that,
Total no of red balls = 4
Total no of green balls = 6
The probability of not drawing a white ball in one draw be, 
We need to find the number of white balls. Let there are x balls.
The probability of drawing a white ball = 1 - the probability of not drawing a white ball
= 1 -2/3
= 1/3
Using the formula for solving probability of having a white ball.

Hence, there are 5 white balls.
Answer:
for question 4, 1/3 is the probability since there are 6 sides and there are two numbers on a die less than 3, 2 and 1.
2 and 1 are 2 of the 6 numbers on the die.
so 2/6
but we have to simplify!
divide 2 by 2 and 6 by 2
1/3 done!
Step-by-step explanation:
Answer:
y = 3x-16
Step-by-step explanation:
two points where the line goes through is (5,-4) as mentioned and (0,-16)
It is exponentially each time you are dividing by 4/3
