One possible set is 1 1/10, 1 3/10, 2 1/10, 2 2/10, and 3 3/10.

The GCF is 13.

Pupils in different countries learn different parts of mathematics so, without knowing which country the question refers to, it is not possible to be sure of the answer. However, I suggest that it is coordinate geometry, also known as algebraic geometry or analytical geometry.

Muḥammad ibn Mūsā al-Khwārizmī died in 850.

im not sure

he was an polish astronomer

The GCF is 5.

In the UK, yes. It is up to the pupil to check out the tutor.

1473-1543

Wikipedia information about him indicates that he was Catholic.

Archimedes, along with countless other mathematicians and philosophers, helped lay the foundation for the development of geometry. Euclid assembled all of the geometric formulae known in ancient Greece and Egypt into his 13 volume work called 'Elements' over 2,000 years ago.

Nobody really knows because Euclid' life info has been lost through the years, and do you like pepperoni pizza?

yes

solved pi...

Both Diophratus (300AD) and Al-Khwarizmi(800 AD) are often called the "father of algebra". I like Al- Khwarizmi because he use the term "al-jabr" which now is known as algebra. Al jabr ( arabic) means, when loosely translated, "what I do to one side of the equation, do the the other"

It is: 16-4 = 12

The measurements make for a very steep slide with a gradient of nearly 3.3! Anyway, given these measurements, the bottom of the slide needs to be attached approx 25.6 inches from the bottom of the tower.

You cannot.

The GCF is 2.

7/12 is the smallest at 58.33%

pi*radius2 = 425 sq m

Divide both sides by pi and then square root both sides to find the radius:

radius = 11.63106623 m

Yes. He also had help from one person

He thought about philosophy and science.
