Answer:
A. 30000
B. 12000
Step-by-step explanation:
Find out how much spectators leave in 1 minute.
1 second = 5
1 minute = 5 x 60 = 300 (60 seconds)
20 minutes = 300 x 20 = 6000
Since there were only 80% of the full capacity of spectators and after minutes it became 60%...
80% - 60% = 20%
20% = 6000
1% = 6000 ÷ 20 = 300
100% = 300 x 100 = 30000
1 minute = 300 spectators leaving
1 hour = 300 x 60 = 18000 (60 minutes)
30000 - 18000 = 12000
Answer: B
Step-by-step explanation:
Answer:
x=1
Step-by-step explanation:
4 - 5(3- 2x) = -2x + 1
Distribute
4 - 15 +10x = -2x+1
Combine like terms
-11 +10x = -2x+1
Add 2x to each side
-11+10x+2x = -2x+2x +1
-11+12x = 1
Add 11 to each side
-11 +11 + 12x = 11+1
12x = 12
Divide each side by
12x/12 = 12/12
x = 1
Answer:
x = 11
Step-by-step explanation:
Since this is a triangle, all interior angles add up to 180 so:
57 + 73 + 3x + 17 = 180
3x + 147 = 180
3x = 180 - 147
3x = 33
x = 11
Answer:
Carlos bought 80 feet of wire for $17.60.
Then the price for 1 feet of wire is 17.6/80 = 0.22
=> 30 feet of wire would cost: 30 x 0.22 = 6.6
Hope this helps!
