Answer:
Step-by-step explanation:
The scale factor is given as 1:500,000
i.e. original 500,000 is represented as 1 inch in the map
Hence if 12.7 inches on the map, this is a question of direct variation
So actual distance = 12.7(500000) = 6350000
Answer:
About 700 billion bacteria
Step-by-step explanation:
Given


Required
Number of bacteria in 1 oz

Multiply both sides by 28


Recall that

This means:

Answer:
<h2>1. V = 100 in³</h2><h2>2. h = 10 in</h2>
Step-by-step explanation:
The formula of a volume of a cylinder:

<em>B</em><em> - base area</em>
<em>h</em><em> - height</em>
<em />
1. We have
<em>h = 5in, B = 20 in²</em>.
Substitute:

2. We have
<em>B = 20.7 in², V = 207 in³</em>.
Substitute:
<em>divide both sides by 20.7</em>
