Answer:
about 5.5
Step-by-step explanation:
so 5cm. Just trust me i dont know how to explain but i know its right.
After the first, we have 2/3 left, the second and third took 1/6 and 1/4, or 5/12 (1/6+1/4=2/12+3/12=(2+3)/12=5/12). Now, we just subtract 5/12 from 2/3, so 2/3-5/12=8/12-5/12=(8-5)/12=3/12=1/4. This means we have 1/4 of an hour left.
Answer:y=1
Step-by-step explanation:
Nearly 81 moons will be required to equate the mass of moon to the mass of earth.
Step-by-step explanation:
Mass of earth is 5.972*10^24 kg.
Mass of the moon is 7.36*10^25 g = 7.36*10^22 kg
As mass of the Earth is given as 5.972 * 10^24 kg and mass of the moon is given as 7.36 * 10^22 kg, then the number of moons required to make it equal to the mass of earth can be calculated by taking the ratio of mass of earth to moon.
Mass of Earth = Number of moons * Mass of Moon
Number of Moons = Mass of Earth/Mass of moon
Number of moons = 5.972 * 10^24/7.36*10^22= 81 moons.
So nearly 81 moons will be required to equate the mass of moon to the mass of earth.
The probability that that a randomly selected student will buy a raffle ticket and win a prize = 0.03
Step-by-step explanation:
Step 1 :
Given,
The percentage of students buying the raffle ticket = 30%
The percentage that the student who bought the ticket wins the prize = 10%
We need to determined the probability that randomly selected student will buy a raffle ticket and win a prize.
Step 2 :
The probability that a student buys the raffle ticket = 
The probability that a student wins a prize = 
= 
The probability that a student who buys the ticket wins a price can be computed by taking the product of the above 2 probabilities.
= 
× = 
= 0.03
Step 3 :
Answer :
The probability that that a randomly selected student will buy a raffle ticket and win a prize = 0.03
