speed of plane flying east = x
speed of plane flying west = x+75
total speed = 2x+75
distance after 4 hours ( 7-3) = 8x+300
8x+300 = 5460
8x = 5160
x = 5160/8 = 645
speed of plane flying east = 645 km/h
The
formula
, where r! is 1*2*3*...r
is the
formula which gives us the total number of ways of forming groups of r objects out of n objects.
for
example, given 10 objects, there are C(10,6) ways of forming groups of 6, out
of the 10 objects.
<span>Thus, there are C(6, 3) many ways of forming different triples out of 6.</span>

Answer: A.20
Scale factor = 1.2
the missing side is 48
Answer:
it w > 7
Step-by-step explanation:
because 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 ybecause 120> 3 = w56 (56+30) 86>5 y
