This is question of geometric sequence, equation of growth for this matter. The explicit formula for geometric sequence is given by:
a(n) = a(0)r^(n-1)
where;
a(n) = population after time "n"
a(0) = Initial population = 65
n = time = 5 weeks
r = common ratio = (100+30)% = 1.3
Substituting, beetles after 5 weeks will be;
a(5) = 65*1.3^(5-1) = 185.65 ≈ 186 beetles
Step-by-step explanation:
x+50%x=30
150%=30
1.5x=30
x=20

Answer:
Evan has $560 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $236.27. He buys 3 bicycle reflectors for $14.61 each and a pair of bike gloves for $15.56. He plans to spend some or all of the money he has left to buy new biking outfits for $57.65 each.
Step-by-step explanation:

Answer:B and E
It is B and E because it’s exponent matches the equation. In B, there are 2 fives and the exponential form shows 5 to the power of 2. In E, there are 6 sevens and the exponential form shows 7 to the power of 6.
