Answer:
Given n collinear points, 2(n -1) or 2n - 2 rays can be named
Step-by-step explanation:
When we talk of collinear points, we mean points that lie on the same straight line.
For 3 collinear points we can have 4 rays
For 4 collinear points, let’s say ABCD
A B C D
The rays are AB BA BC CB CD and DC making a total of 6
For 5 collinear points,
A B C D E
The rays are;
AB BA BC CB CD DC DE ED which makes a total of 8
For 6 collinear points, we have;
A B C D E F
The rays are;
AB BA BC CB CD DC DE ED FE EF which makes a total of 10
So what pattern do we notice?
3 points 4 rays
4 points 6 rays
5 points 8 rays
6 points 10 rays
7 points 12 rays
So using the pattern
n rays = 2n - 2 rays or simply 2(n - 1) rays
Answer:
Greatest = 699,999
Least = 600,900
Step-by-step explanation:
6 digit numbers
9 in the Hundred place
3 fewer hundred thousands than hundred
9 - 3 = 6
Hundred thousand = 600,000
Hence, greatest 6 digit number
Hth__TTh__Th__H__T__U
6____9____9___9__9__9
600,000 + 90,000 + 9,000 + 900 + 90 + 9
= 699,999
Hence, least 6 digit number
Hth__TTh__Th__H__T__U
6____0____0___9__0__0
600,000 + 00000 + 0000 + 900 + 00 + 0
= 600,900
It is possible to prove that the right triangles are congruent through the right angle hypotenuse side theorem.
Answer:
$5700 - $5500= $200
Explanation:
The total installments: 24 ($175) = $4200
The hire purchase price: $1500 + $4200 = $5700
The amount saved by paying cash: $5700 - $5500= $200
