<span>Approximately 25.
Of the 5 grades of sand used in the United states, medium sand has particles ranging from 0.25 mm to 0.5 mm. For convenience, I'll use 0.5mm as the diameter of a grain of sand. Human cells range from a volume of 30 cubic micrometers (human sperm cell) up to 4 million micrometers (human egg cell). For the average human cell, I'll use an osteoblast with a volume of 4000 cubic micrometers or a diameter of 2x10^-5 meters.
Now just take the diameter of a grain of sand and divide by the diameter of a human cell.
5 x 10^-4 / 2x10^-5 = 5/2 x 10^(-4 - -5) = 2.5x10^1 = 25
So the diameter of a grain of sand at 0.5 mm is approximately 25 times larger than that of a human cell at 0.02mm</span>
Literal equation:
we know that
literal equation is equation of more one variable
for example: ![2x+3y=1](https://tex.z-dn.net/?f=%202x%2B3y%3D1%20)
And we can solve such equations only if we are given two such equation
because it has two variables
One variable equation:
such equation has single variables
for example:
![3x=21](https://tex.z-dn.net/?f=%203x%3D21%20)
we don't need any other equation
we can solve for variables from single equation itself
because it has only one variable that is x
1 inch= 12 miles
Multiply 6 1/2 inches by total number of miles per 1 inch (12).
= 6 1/2 * 12
convert to improper fraction
= 13/2 * 12
multiply numerators
= (13*12)/2
multiply in parentheses
= 156/2
divide
= 78 miles
ANSWER: (A) 78 miles
Hope this helps! :)
Ahh... this is pretty easy!!
.
Locomotive is 40 feet.
.
Model is 16.
.
So?
.
Divide 40 by 16!!
.
What's that?
.
2.5.
.
So your answer choice is 2.5
.
Hope I helped!!
Answer:
80
Step-by-step explanation:
Look at the box plot and look at each line.
The first line that is all the way to the left, that is the Quartile 1.
The last line all the way to the right, that is Quartile 3.
Now lets look at the box part.
The beggining of the box is the minimum.
The ending of the box is the maximum.
The middle line is the median.
How I remember it is Median=Middle
Hopw this hels :D
