Step-by-step explanation:
In the equation

, a is the initial amount and b is the growth factor. So our initial amount is 30 and our growth factor is 8.3. Your correct choice for this is A.
The first question 10 and the next one is 40 the next one is 30
L = 4D + 54 <== ur equation
the crew worked for 31 days...so sub in 31 for D
L = 4(31) + 54
L = 124 + 54
L = 178 miles <==
the formula for this questions would be pie multiplyed by d
so to solve this problem you would 3.14* 120 which equals 376.8
what you need to do to find six laps is multiply 376.8 with 6
which gives you 2260.8
answer- 2260.8
