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:
The answer is 5 hours
Step-by-step explanation:
First u add the part and service charge toghther which is 75 and then 225 minus 75 is 150 so u divide 150 and 30 and u get 5 which is your answer.

Answer:
Step-by-step explanation:
Upon factoring all terms we are left with the product of
[(x-4)(x+6)(x-6)]/[5(x-6)(3x+5)(x-4)]
The (x-4)s and (x-6)s cancel out and we are left with
(x+6)/(5(3x+5)) which is also equal to
(x+6)/(15x+25)
32.4*0.69=22.149
...
45=3*3*5, 63=3*3*7 The greatest common factor is the product of shared primes of the numbers prime factorization. In this case 3*3=9 is the product of shared primes so the greatest common factor is 9
Remember that
the formula to calculate the combination is equal to
nCr=n!/[r!(n-r)!]
in this problem
we have
n=4
r=3
substitute the given values
4C3=4!/[3!(4-3)!]
4C3=4!/[3!(1)!]
4C3=4*3!/3!
4C3=12
the answer is 12
For 2 scoops
we have
n=4
r=2
substitute
4C2=4!/{2!(4-2)!]
4C2=(4*3*2*1)/4
4C2=6
the answer is 6
