Answer:
40 % of the movies
Step-by-step explanation:
first you would do 38÷95, which would give you .4 then you would turn it into a percent, so you have to multiply it by 100, or move the decimal 2 places to the right, which would give you 40. therefore, you're answer would be 40%
Answer:
{x,y,z} = {1,-1,-2}
Step-by-step explanation:
Answer:
Rate of plane 735 km/hr
Rate of wind 65 km/hr
Step-by-step explanation:
Calculation to determine the rate of the plane in still air
Let Va represent the velocity of the airplane
Let Vw represent the velocity of the wind
When flying with the wind:
(Va+Vw)*(6 hours) = 4800
6Va + 6Vw = 4800
6Vw = 4800 - 6Va
Vw=4800/6-Va
Vw = 800 - Va
When flying against the wind:
(Va-Vw)*(6 hours) = 4020 km
6Va - 6Vw = 4020
Substitute 800-Va for Vw and solve for Va:
6Va - 6(800-Va) = 4020
6Va -4800 + 6Va = 4020
12Va = 8820
Va=8820/12
Va = 735 km/hr
Therefore the rate of the plane in still air is 735 km/hr
Calculation to determine the rate of the wind
Rate of wind:
Vw = 800 - Va
Vw= 800 -735
Vw= 65 km/hr
Therefore the rate of the wind is 65 km/hr
Your answer should be written as two fractions, with an equal sign between them. This could help you later to solve x.
8/64 = 2/x
Again, these should be written as fractions.
