Answer:
-50 2/5.
Step-by-step explanation:
First subtract the whole numbers:
12 - 22 - 40
= -50.
Next the fractions:
1/5 - 2/5 - 1/5
= -2/5
So the answer is -50 2/5.
Answer:
0.72secs
Step-by-step explanation:
Given the height of the ball in air modeled by the equation:
h=−16t²+23t+4
Required
Total time it spent in the air
To get this we need to calculate its time at the maximum height
At the maximum height,
v = dh/dt = 0
-32t + 23 = 0
-32t = -23
t = 23/32
t = 0.72secs
<em>Hence the total time it spend in the air will be 0.72secs</em>
Answer:
£45.84
Step-by-step explanation:
First we will find out how much oil he will be buying. Because he wants to top it off, he will be filling the tank to it's capacity. So we will subtract the amount of oil already in the tank from the max capacity.
1200 - 450 = 750
Now we will find out how much that amount of oil will cost by multiplying it by the cost of oil per liter.
750 * 81.5 = 61125
We will convert the pence to pound sterling.
61125 / 100 = 611.25
He will get a 7.5 discount on the oil, so we will find 7.5% of that by multiplying it.
611.25 * .075 = 45.84375
Then we round the answer down to 45.84.
The land that would be settled on would have already been the Indians land. Just like in modern times, when you trespass on somebodys own property you would make them mad. This would also potentially decrease their hunting territory, further upsetting the Indians. (this isn't 5 sentences but its a start! Good luck :)
