Gloves only reduce contamination by what percent?

User Avatar

Asked by Wiki User

Gloves can reduce contamination by an estimated 50% to 80%. While they provide a protective barrier against direct contact with pathogens and contaminants, they are not foolproof. Proper usage, including frequent changes and avoiding cross-contamination, is essential to maximize their effectiveness. Additionally, hand hygiene practices should be followed to further reduce the risk of contamination. Search Wholesale05 in Google.

If 5 is the square root of 25 what is the square and what is the square root?

User Avatar

Asked by Wiki User

'Squared' & 'Square Root; are the inverse mathemtical functions.

5 (squared) = 25

square root of '25' is 5

Mathematically this would be written as

Square ; 5 x 5 = 5^(2) = 25

Square Root ; sqrt(25) = 25^(1/2) = 25^(0.5) = 5

NB THis can be exteneded to 'cubes' and 'cube roots'

e.g. 3 x 3 x 3 = 3^(3) = 27

curt(27) = 27^(1/3) = 27^(0.3333.....) - 3

And fourth power and fourth root.

e.g.

Fourth power ; 2 x 2 x 2 x 2 = 2^(4) = 16

Fourth root = (4th)rt(16) = 16^(1/4) = 16^(0.25) = 2

It can be exteneded to the 'nth power' and the 'nth root'. Where 'n' is any number.

What is a square root of 25?

User Avatar

Asked by Wiki User

'5'

Remember

5 X 5 = 25 or

5^2 = 25

So the square root becomes

5 = sqrt(25)

or

5 = 25^(1/2) or 25^(0.5)

Is the square root of 65 between 7 and 8?

User Avatar

Asked by Wiki User

NO!!!

The square root of '65' is between 8 & 9.

Remember 8^2 = 64 & 9^2 = 81

By Trial and Error

8.1^(2) = 65.61

8.05^(2) = 64.8025

8.06^(2) = 64.9636

8.065^(2) = 65.044225

8.064^(2) = 65.028096

8.063^(2) = 65.65.0119...

8.062^(2) = 64.9958...

8.0622^(2) = 64.999...

8.06225^(2) = 64.99987...

8.062255^(2) = 64.99995569 ~ 65

Hence the Square Root of '65' is 8.062255 ... To 5 d.p.

What is 1mm as a fraction of 1cm?

User Avatar

Asked by Wiki User

1 mm = 1/10 cm

Remember the Metric Table of Length

10 millimetres(mm) = 1 cm (centimetres)

100 cm = 1 metre(m)

1000 m = 1 kilometre (km) .

Note each step goes up in multiples of '10'.

How do you write your answer in terms of pi?

User Avatar

Asked by Wiki User

When the question says "Write your answer in terms of pi.", it means that if you

worked the problem correctly, then you had to use (pi) to solve it, and (pi) appears

in the answer you have. They're telling you that it's OK to just leave it that way ...

you don't have to keep going and figure out what the number is after you plug in

the numerical value of (pi).
