Answer:
it is 0.91<u>6 (</u>the six is repeated. a line under a number means repeated in this case)
Step-by-step explanation:
First you take 3 1/4 and turn it into 13/4 and turn 2 1/3 into 7/3 and transform those into decimals 13/4 = 3.25 and 7/3 = 2.<u>3</u> and subtract which is 0.95 plus the fact that the three is repeated which gets your answer of 0.91<u>6</u> however you should say that if they want you to simplify it to two/three decimals, it is 0.95 but if they want it exact it is 0.91<u>6</u> with the six being repeated
5.a) since the distance is 140km, and the time is 2hours, and we need the speed in km/h, we have to divide the distance by time, and we will get the speed: s=d/t = 140km/2h = 70km/h
b) the distance is 43km, and the time is 30 minutes, which is 0,5hours, we do the same thing here, with given formula : s=d/t = 43km/0,5h = 86km/h
Answer:
I think it is this because it seems as if It is 2 separate equations.
a.x=9-2y/3
b.x=3+y/3
Answer:
Step-by-step explanation:
Since it's a coin flip, each coin flip is independent of any other. Each time Steven flips the counter it has the same chance of landing on either side. It's true the on the first throw, and it's true on the 1000th throw.
Even if, extremely improbable, the first 22 flips landed on the blue side, that predicts nothing regarding the outcome of the 23rd flip.
That's all assuming the counter/chip/coin is properly and evenly balanced.... since we have no indication otherwise in the problem definition, we have to assume it's the case.
