Answer:

About 700 billion bacteria

Step-by-step explanation:

Given

1oz \approx 28g

1g = 25\ billion\ bacteria

Required

Number of bacteria in 1 oz

1g = 25\ billion\ bacteria

Multiply both sides by 28

28 * 1g = 25\ billion\ bacteria * 28

28g = 700\ billion\ bacteria

Recall that

1oz \approx 28g

This means:

1oz \approx 700\ billion\ bacteria

The perimeter of the pentagon with apothem of 5cm is 28.87cm

<h3>How to calculate the perimeter of a pentagon</h3>

The sum of all the external sides of the pentagon is its perimeter.

First we need to calculate the half of one of its sides using the SOH CAH TOA

tan 30 = x/5

x = 5 tan 30

x = 2.89

One of the sides = 2(2.89) = 5.77 cm

Perimeter of th pentagon  = 5(5.77) = 28.87

Hence the perimeter of the pentagon with apothem of 5cm is 28.87cm
