Answer:
24 practices in 9 weeks
Step-by-step explanation:
Rate = 8 times / 3 weeks
8 times / 3 weeks * 9 weeks = 24 times

Answer:

Step-by-step explanation:
2+4=6
21X6=126
126+7=133
133/6= 22R1
Answer:
57.14%
Step-by-step explanation:
So if he removes an orange ball from the bag, that means there are 8 white golf balls and 6 orange golf balls - 14 balls in total
8 balls of the 14 are white, so to find the percent we can set up a proportion
8/14=x/100
you can simplify 8/14 to 4/7
4/7=x/100
cross multiply
7x=400
divide by 7 on both sides
x=57.14%
114 rabbits are released in an isolated area free of predators
When month =0 , the rabbits = 114
3 years = 36 months
When months = 36 , then rabbits = 912
(0,144) and (36, 912)
Exponential growth equation is y = ab^x
Plug in each point and solve for 'a' and 'b'
so a= 114
(36, 912)
Divide both sides by 114 and then take 36th root on both sides
8 = b^36
b = 1.05946
so exponential equation is
x is the number of months and y is the population
to find the population be after another 3 months
Plug in 36+3= 39 for x and find out y
y= 1084.43336
so , 1084 rabbits after another 3 months
