Answer:
The speed of plane against wind S 1 = 1020 kmph And
The speed of plane with wind S 2 = 1260 kmph
Step-by-step explanation:
Given as :
The distance of airplane against the wind = D 1 = 3060 km
The time taken in against the wind = T 1 = 3 hours
The distance of airplane with the wind = D 2 = 7560 km
The time taken in with the wind = T 2 = 6 hours
Now, Speed of plane against the wind = 
So, S 1 = 
Or, S 1 =
= 1020 kmph
Similarly
Speed of plane with the wind = 
Or, S 2 = 
Or, S 2 =
= 1260 kmph
Hence The speed of plane against wind S 1 = 1020 kmph And
The speed of plane with wind S 2 = 1260 kmph Answer
for the first truck 1680 / 14 = 120 liters used
the second 1680 / 12 = 140 litres used
so 140-120 = 20 liters <span>the second truck used more </span>
Answer:
P(X<65)=0.9452
Step-by-step explanation:
This is a normal distribution problem.
-Given the mean age is 53 years and the standard deviation is 75, the probability of dying before age 65 is calculated as:

#We check the value of z=1.60 on the z table:

Hence, the probability of dying before 65 is 0.9452
The answer is 30 degree in rotation.
Answer:
8 Shampoo Concentrate
Step-by-step explanation:
There's a ratio of 9:2 so for every 9 cups of water there's two cups of shampoo concrete.
We'll need 9 multiplied by 4 is 36
so we need to multiply 2 with 4
4 multiplied by 2 is 8
