Answer:
A) The width is 12 cm; the average time is 3 minutes
Step-by-step explanation:
Cross multiply.
5 × y = 3 × 20
5y = 60
5y ÷ 5 = 60 ÷ 5
y = 12
The width is 12 cm. Moving onto the time.
Cross multiply.
4 × y = 12 × 1
4y = 12
4y ÷ 4 = 12 ÷ 4
y = 3
The time is 3 minutes.
Answer:
perpendicular line through a point on a line
Step-by-step explanation:
The circle centered at C seems intended to produce point D at the same distance as point B. That is, C is the midpoint of BD.
The circles centered at B and D with radius greater than BC seems intended to produce intersection points G and H. (It appears accidental that those points are also on circle C. As a rule, that would be difficult to do in one pass.)
So. points G and H are both equidistant from points B and D. A line between them will intersect point C at right angles to AB.
Segment GH is perpendicular to AB through point C (on AB).
Hilbert axioms changed Euclid's theorem by identifying and explaining the concept of undefined terms
<h3>What was Hilbert's Axiom?</h3>
These were the sets of axioms that were proposed by the man David Hilbert in the 1899. They are a set of 20 assumptions that he made. He made these assumptions as a treatment to the geometry of Euclid.
These helped to create a form of formalistic foundation in the field of mathematics. They are regarded as his axiom of completeness.
Hilbert’s axioms are divided into 5 distinct groups. He named the first two of his axioms to be the axioms of incidence and the axioms of completeness. His third axiom is what he called the axiom of congruence for line segments. The forth and the fifth are the axioms of congruence for angles respectively.
Hence we can conclude by saying that Hilbert axioms changed Euclid's theorem by identifying and explaining the concept of undefined terms.

Answer: 292 tiles
Step-by-step explanation:
To find the number of tiles needed , we need to know the area of the hexagonal tiles and also the area of the room.
<u>Area of hexagon</u>
The area of hexagon is given as :
Area =
Where a is the length of side.
Therefore:
A =
A = X 400
A = (400 x 3 x ) / 2
A =
A = 1039.23
Also to find the area of the room , we must first convert from m to cm
6.25 m = 6.25 x 100 cm
6.25m = 625 cm
4.85m = 485cm
Therefore: Area of the room = length x breadth
Area = 625 x 485
Area = 303125
Therefore , the number of tiles needed = area of the room / area of hexagon
Number of tiles = 303125/ 1039.23
N = 291.6823032
Therefore , the number of tiles needed ≈ 292
