4(4+2) + 5(5+3)
4x6 + 5x8
24 + 40
64 is your answer
Exp prob (red) = 24 / 60 = 4 / 10 = 2/5
Theoretical prob (red) = (1/2)
Exp prob (blue) = 14 / 60 = 7 / 30
Theoretical prob (blue) = 1/6
Exp prob ( yellow) = 22/ 60 = 11/30
Theoretical prob ( yellow) = 2/6 = 1/3
Answer:
√290
Step-by-step explanation:
( 2 - 3 )^2 + ( 8 + 9 )^2
= ( - 1 )^2 + 17^2
= 1 + 289
= 290
= √290
Answer:
40 hours
Step-by-step explanation:
Lets take "x" as the # of hours it takes the lava to reach the sea
since there is a lava flow of 0.5 kilos per hour
we will multiply "x" with 0.5
0.5x
now the tube system is 20 kilometers long
this means that at a rate of 0.5 kilos per hour the lava will reach the sea once it is 20 kilometers deep
so
0.5x=20
divide "0.5" by both sides to eliminate the coefficient

x=40
it will take 40 hours for the lava to reach the sea
Hope this helps!
