Answer:
2) 30, 70, 80
Step-by-step explanation:
Well there has to be <em>3 angles</em> that all add up to <em>180°</em>.
1)
100+130+130
=360
2)
30+70+80
= 180
3)
25+3+35
=63
4)
45 + 105 + 120
=150
150+120
270
Alot! So the ones with 5 like 15,25,35,45,55,65,75,85,95! Each one inbetween is 10 so it would be 80
Answer:
8:24
Step-by-step explanation:
since 1:3 is already given to you
and 8:_ needs to be found
you know that the new ratio is 8 times bigger than the original one
multiply 1 by 8 and you get 8
multiply 3 by 8 and you get 24
You have a total of 5 cans, because 1+3+1=5.
1 can is tomato soup.
So, the probability of selecting tomato soup randomly is 1/5.
Answer:
Step-by-step explanation:
b and c are the speeds of the boat and current, respectively.
Traveling upstream, the boat moves b-c km per hour.
Traveling downstream, the boat moves b+c km per hour.
b-c = (60 km)/(½ h) = (120 km)/h
b+c = (60 km)/(⅓ h) = (180 km)/h
Adding the equations together,
2b = (300 km)/h
b = (150 km)/h
c = (30 km)/h
