Answer:
x=70
Step-by-step explanation:
We can find the angle with 120 by subtracting 180-120=60
60+50=110
180-110=70
60+50+70=180
3. He started out with 36 cards and then added 372 more. So now he has a total of 408 cards. He has 5 folders each with the same number of cards. 408 divided by 5 = 45 with three left over.
Answer:
4.8 hours
Step-by-step explanation:
Distance = speed × time
If Tim drove 4 hours at 60 miles per hour
Than he drove a total of 4×60 miles
He drove 240 miles
Time = distance ÷ speed
If he drove 240 miles at 50 miles per hour
Than he took 240÷50 hours
He took 4.8 hours (4 hours and 48 minutes)
Answer:
position 1 5 8 12 19 25
term -8 8 20 36 64 88
Step-by-step explanation:
(n - 1) is position ( n ∈ N)
d is the distance between the numbers in the sequence
a1 is the first number in the sequence
we have the fuction: a(n) = a1 + (n - 1)d
see in the table, with position = 1, term = -8 => a1 + d = -8
position = 25, term = 88 => a1 + 25d = 88
=> we have: a1 + d = -8
a1 + 25d = 88
=> a1 = -12
d = 4
=> a(n) = -12 + 4(n - 1)
=> term = 8, position = (8 + 12)/4 = 5
position = 8, term = -12 + 4.8 = 20
term = 36, position = (36 + 12)/4 = 12
position = 19, term = -12 + 4.19 = 64
