All 4 stages span a total of 4 weeks or 28 days.

Egg - 2 days
Larva - 7 days
Pupa - 5 days
Adult - 14 days

This means that the larva exists for 7/28 = 25% of the time.

So, 25% of the randomly selected developing bees would be larva.

25% of 200 is 50. So, the answer is A.

Edit: The question is ambiguous. If by developing bees they exclude all the adult bees, then larva exist for 50% of the time and the answer would be 100.

4 more than one third of a number n is 6. An equation is? The solution is n =?

harkovskaia [24]

Answer:

$\frac{1}{3}$ n + 4 = 6

Step-by-step explanation:

Given problem:

4 more than one third of a number n is 6

Unknown:

The equation = ?

Solution of the number = ?

Solution:

let the number = n

So, 4 more than one third of a number;

One third of n = $\frac{1}{3}$ n

4 more;

$\frac{1}{3}$ n + 4

is 6;

$\frac{1}{3}$ n + 4 = 6 (equation of the expression)

Let us now solve the equation:

$\frac{1}{3}$ n + 4 = 6

$\frac{1}{3}$ n = 6 - 4

$\frac{1}{3}$ n = 2

n = 6
