Speech-impaired people can communicate with the help of new electronic devices. The devices
contain circuit switches that are 9 x 10
mm in
length. A switch is placed beside a grain of sand.
The grain of sand has a diameter of 0.54 mm.
How many switches placed end-to-end are
needed to equal the diameter of the grain of
sand?

yes because they have the same amount of green and blur marbles.

idk what the heck he answer is, i’m just putting this here so i finish my account

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
