If the last number is 5 or larger than 5, then you round up, but if it less than 5, than you round down.
Ex: 42.591, round to nearest hundredth:
Because 1 is less than 5, then we keep the 9 there so the answer is 42.59

Ex: 31.5727, round the number to the nearest thousand:
Because 7 is greater than 5, then we round the 2 to 3 so the answer will be 31.573.

It depends. If it's .5 or above, round up.
If it's .4, round down

It is estimated that world reserves of oil currently stand at 2625
seraphim [82]

Answer:

  35.4 years

Step-by-step explanation:

The annual consumption (in billions of units) is described by the exponential function ...

  f(t) = 45.5·1.026^t

The accumulated consumption is described by the integral ...

  \displaystyle\int_0^t{f(x)}\,dx=45.5\int_0^t{1.026^x}\,dx=45.5\left(\dfrac{1.026^t-1}{\ln{1.026}}\right)

We want to find t such that the value of this integral is 2625, the estimated oil reserves.

  2625 = 45.5/ln(1.026)·(1.026^t -1)

  2625·ln(1.026)/45.5 +1 = 1.026^t ≈ 1.480832 +1 = 1.026^t

Taking natural logs, we have ...

  ln(2.480832) = t·ln(1.026)

  t ≈ ln(2.480832)/ln(1.026) ≈ 35.398

After about 35.4 years, the oil reserves will run out.

How do you solve this system of linear equation by substitution <br><br>x-3y=-12<br>y=2x+9
Ainat [17]
Finding x:
If y=2x+9, substitute y into the equation x-3y=-12.
You will get:  x-3(2x+9)=-12
Now, distribute:  x-6x-27=-12
Add like terms:  -5x-27=-12
Add 27 to both sides:  -5x=15
Divide both sides by -5:  x=-3

Now, substitute this value of x into the equation to find y:  y=2(-3)+9
Multiply:  y=-6+9
Add:  y=3

Here is the solution:  (x,y)=(-3,3)

Hope this explanation helped!
