In this item, we are informed that the order of the entries does not matter in determination the number of ways in which the Archie can choose for his party. Because the arrangement or order is not important, this type of problem uses the concept of COMBINATION.
The equation for combination is,
nCr = n!/((n - r)!(r!))
nCr is read as "combination of n taken r".
Substituting the known values to the equation,
15C6 = 15! / ((15 - 6)!(6!))
= 5005
Hence, there are 5005 ways in which Archee can choose the 6 entrees for his party.
Answer:
<7 =73
<8=107
Step-by-step explanation:
all odd angles equal each other in that shape, so <7=<3 and all even equal other evens. <8=<4
to find angle 8, I subtracted 73 from 180.
180-73=107
Answer:
6a + 13
Step-by-step explanation:
2a + 4a = 6a
8 + 5 = 13

General Equation of a circle with centre (a, b) and radius r
</span>------------------------------------------------------------------------------------<span>
(x − a)</span>² + (y − b)² = r²
------------------------------------------------------------------------------------
Substitute (6,0) and r = 6
------------------------------------------------------------------------------------
(x - 6)² + (y - 0)² = 6²
(x - 6)² + y² = 36
------------------------------------------------------------------------------------
Answer: (x - 6)² + y² = 36 (Answer A)
