Because if you round 781 up to the nearest hundred, you would simply look at the number after the 7. If it is bigger than 5 then you round up
Answer:
a=5/2 a=2.5
Step-by-step explanation:
isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
y<7 since if you subtract 1 from both sides and then divide both sides by 5 you get y<7
Answer:
1/8 Kg de miel.
Step-by-step explanation:
In one day, there are 24 hours. In 1 hour, there are 3,600 seconds. So, that means that there are 86,400 seconds. Also, in 1 day, the short hand which denotes the number of hours, makes 2 revolutions around the clock. Its distance traveled would be twice the perimeter of the circle.
Distance traveled by hour hand = 2(2πr) = 4πr₁
In 60 s, the long hand, which denotes numbers of minutes, makes one revolution around the clock. Since there are 86,400 seconds in a day, that would be a total of 1,440 revolutions.
Distance traveled by minute hand = 1,440(2πr) = 2,880πr₂
Difference = 2880πr₂ - 4πr₁ = 4π(720r₂ - r₁), where r₁ is the length of hour hand and r₂ is the length of minute hand.
