Step-by-step explanation:
The spores always x3 after a month so going a month back they ÷3 instead so 900÷3 is 300 spores on the first month
Why not write all of the numbers in decimal fraction form, to make them easier to compare?
68 2/3 = 68.666...
72 1/2 = 72.500
68 3/10 = 68.300
74 7/11 = 74.636...
68 1/2 = 68.500
550/8 = 68.750
Now ask yourself: Which of the last four numbers is between 68.666.. and 72.500?
Answer:
22π in.
Step-by-step explanation:
circumference: 2 × π × r
=> 2 × π × 11 = 22π
For 6 the answer is c because 1 fourth goes into one and a half 6 times so you do 6 times 4 feet which is 24 feet
