By definition we have to:
 Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large or too small to be written in a conventional manner.
 The use of this notation is based on powers of base 10.
  A number written in scientific notation follows the following pattern:
 m * 10 ^ e

 The number m is called "mantissa" and e the "order of magnitude"
 For this case we have:
 0.000007
 Using the definition, we have that the measure of the diameter in scientific notation is:
 0.000007 = 7 * 10 ^ {-6}

 Answer:
 
An expression that represents this diameter, in meters in scientific notation is:
 
7 * 10 ^ {-6}

at 12pm there are 855 people in the zoo by 5pm 4/5 of the children have left and ³/₄ of the adults have left. There are now 36 m
12345 [234]

Answer:

300 Adults 555 Children

Step-by-step explanation:

What we know:

Firstly, at 5pm there were 36 more Children (C) than Adults (A)

So.....C = A + 36

Secondly, at 12pm there were 5 x more Children and 4 x more Adults and the total was 855

So 4A + 5C = 855

——-

Now use ‘C = A + 36’ and get rid of all ‘C’ in the second equation.....

4A + 5C = 855

becomes......

4A + 5 (A + 36) = 855

Multiply the brackets (5 x A) and (5 x 36):

4A + 5A + 180 = 855

Take off 180 from both sides:

4A + 5A = 675

Therefore 9A = 675

Divide by 9:

A = 75

We know C is A + 36

C = 111

At 5 pm - A = 75 and C = 111

Therefore at 12:

There were 5 x C = 555

And 4 x A = 300
