Answer:
6 knots
Step-by-step explanation:
Let the speed be v knots
then time taken to cover 500 M = 500 / v hrs
fuel consumption /hr = 216 + 0.5v^3
let F be the fuel consumption for trip
= [500/v][216 + 0.5v^3]
= 500[216/v + 0.5v^2]
dF/dv = 500[ - 216/v^2 + v]
d^2F/d^2v = 500[432/v^3 + 1] , i.e. +ve
so setting dF/dv will give a minima
500[ -216/v^2 + v] = 0
or v = 216/v^2
or v^3 = 216
solving, we get v = [216]^(1/3) = 6 knots
Answer:
It is 45.27
Step-by-step explanation:
Answeryou'll be able to ride 14 miles.
Step-by-step explanation:
Your price is 29.50. if the first mile is 3.50 you'll subtract that from the 29.50 you originally had. Now you're left with 26.00. If you divide that by the two dollars you pay for every next mile you'll have 13 miles. Now add that first mile and you have 14. Hopefully this made sense!
Answer:
192 is the missing number in the sequence.
Step-by-step explanation:
Given sequence is 131, 517, ?, 123.
First write the numbers without comma as 131517?123.
Break it in two digit numbers as 13, 15, 17, _ _ 23
Complete the sequence with the missing two digit odd numbers.
13, 15, 17, 19, 21, 23
Now rewrite the sequence without comma again.
131517192123
Place the comma after every three digits.
131, 517, 192, 123
Therefore, the missing number is 192.
1. If Rachel's free-throw percentage is 60%, you can take 4 index cards away since 100 - 40 = 60%. For example, if those 10 index cards represent 10 free-throws, and her percentage is 60%, just take 60 away from the total (100%).
2. For the simulation, it's the same as problem 1. Since 50 is the total amount of shots she is going to take, and you know she is going make 60% of them, take 60% from 50 which gives you 30. That means she will make 30 of them and miss 20 of them
