Answer:
Step-by-step explanation:
Two possible patters of sitting:
⇒
⇒
⇒ Three ways can be used to seat each set of three people, for a total of six.
⇒ There are two groups
2 × 3 = 6 (ways in six groups.)
*The two options can be distributed in two groups.
⇒ Total methods are equal to 6 * 6 * 2 = 72 ways.
Well 125 is 100 + 25. Put those into decimal form, separately, then add them together.
100 --> 1.0
25 --> 0.25
1.0 + 0.25 = 1.25
Change from decimal to fraction form:
1.25 --> 1&1/4
I don’t know exactly what you’re asking, but if they are splitting the cost it would be 349.99 divided by 4, which is 87.49 (87.50)
Answer:
Step-by-step explanation:
an = a1 * r^(n - 1)
a1 = first term = 5
r = -2
n = nth term of the sequence
so it starts with 5
second term is :
an = a1 * r^(n - 1)......for second term
a2 = 5 * -2^(2 - 1) =
a2 = 5 * -2^1
a2 = 5 * -2
a2 = -10
an = a1 * r^(n - 1)....looking for a3
a3 = 5 * -2^(3 - 1)
a3 = 5 * -2^2
a3 = 5 * 4
a3 = 20
an = a1 * r^(n - 1)....looking for a4
a4 = 5 * -2^(4 - 1)
a4 = 5 * -2^3
a4 = 5 * -8
a4 = - 40
an = a1 * r^(n - 1)...looking for a5
a5 = 5 * -2^(5 - 1)
a5 = 5 * -2^4
a5 = 5 * 16
a5 = 80
an = a1 * r^(n-1)...looking for a6
a6 = 5 * -2^(6 - 1)
a6 = 5 * -2^5
a6 = 5 * -32
a6 = -160
Answer:
Commercial = 286 mph
Private = 198 mph
Step-by-step explanation:
Given that:
Commercial flight time = 9 hours
Private jet time = 13 hours
Speed of commercial flight = 2(speed of private jet) - 110
Let
Speed of commercial flight = c
Speed of private flight = p
c = 2p - 110
Recall ;
Distance = speed * time
Hence,
p * 13 = (2p - 110) * 9
13p = 18p - 990
13p - 18p = - 990
-5p = - 990
p = 198 mph
From : c = 2p - 110
c = 2(198) - 110
c = 396 - 110
c = 286 mph
