<span>You can use the fact that the work done is equivalent to finding the center of mass of the water in the tank(which is at the center of the cylindrical cross section, which is 3 ft below the level to which the liquid is pumped. Call this distance h.
You then need the total mass of the liquid, volume X density=m. This is where pi comes in!
Work needed =mgh, where g is the gravitational acceleration.</span><span>

Answer:
Step-by-step explanation:
Since there's no one one number you can add to one number in the sequence to get to the next number, this is not arithmetic. It must be geometric. We need then to find the common ratio. Let's start with the first 2 numbers, find a ratio, and then use it to test for accuracy.
10x = 15 and
x =
If this is in fact a geometric sequence witha common ratio of 3/2, we should be able to multiply 15 by 3/2 to get to the next number in the sequence. Let's try it out:
Good. So the common ratio is 3/2. The formula for an explicit geometric formula is
where a1 is the first number in the sequence and r is the common ratio. Filling in:

Answer:
Here is ur answer.
Step-by-step explanation:
Answer:
$41,875
<u>Extra</u>
a. $17,250 [($780,000 – $90,000) ÷ 40]
b. $366,000 [$780,000 – ($17,250 × 24 yrs.)]
c. $29,600 [($366,000 – $70,000) ÷ 10 yrs.]
Step-by-step explanation:
Step 1: Determine the cost of the asset
Step 2: Subtract the estimated salvage value of the asset from the cost of the asset to get the total depreciable amount

Step 3: Determine the useful life of the asset

Step 4: Divide the sum of step (2) by the number arrived at in step (3) to get the annual depreciation amount

OK, like I explained in the last one KCF, (Keep Change Flip) so our problem is:
8/7÷5/8 So lets Keep 8/7 and change the divide sign to multiplication sign. and then for Flip you flip 5/8 to 8/5. So now our real problem is: 8/7*8/5= (8*8=64) and (7*5=35). So we have 64/35, now you just need to change this improper fraction to a proper one... message me if you have any trouble :)
