The number of viruses was 4000 times greater than number of protozoa.

Step-by-step explanation:

Given,

Number of protozoa = $5*10^5$

Number of viruses = $2*10^9$

Let,

x be the number of times number of viruses is greater than number of protozoa.

Number of viruses = Number of time * Number of protozoa

$2*10^9=(5*10^5)x$

Dividing both sides by $5*10^5$

$\frac{2*10^9}{5*10^5}=\frac{(5*10^5)x}{5*10^5}\\\\4*10^3= x\\x=4*10^3 \\x=4000$

The number of viruses was 4000 times greater than number of protozoa.

A satelite is 5,400 miles from the horizon of earth. Earths radius is about 4000 miles. Find the approximate distance the sateli

kakasveta [241]

Answer:

The distance of Satelite from the earth's surface = 2720.12 miles

Step-by-step explanation:

Below is the calculation for distance:

Use Pythagorean theorem

Distance, d² = 5400² + 4000²

d² = 45160000

d = 6720.12

Subtract the radius to find the distance from earth's surface.

Distance = 6720.12 - 4000 = 2720.12

The distance of Satelite from the earth's surface = 2720.12 miles
