Answer:
See attached. (Note that b, d, f, h, j are cents amounts. All the other letters refer to the dollar amounts only (no cents).)
Step-by-step explanation:
The one deposit is marked with a (+) in the third column of Figure 4.16a. All the other transactions are Payment/Debit transactions. The balance on each line is the balance on the previous line less any payment and plus any deposit on that line. (It's not rocket science.)
If you actually do this in a spreadsheet, it is convenient to let the spreadsheet do the math. It is much easier to let the spreadsheet keep track of dollars and cents in the same column.
It is more difficult to break out cents to a separate column. So, your letter answers apparently need to be the dollar portion only (except as indicated above).
7u^3 - u^2 - 7 + 2u^3 - 4u^2
(7+2)u^3 -(1+4)u^2 - 7
9u^3 - 5u^2 - 7

Total surface area of cone is 176π
<h3>Explanation:</h3>
Surface area of curved surface of a cone is give by π⋅r.l , where r is the radius and l is the slant height of the cone.
Hence surface area of curved surface of a cone is π×8×14=112π .
As surface area of base is π×82=64π .
Hence total surface area is 112π+64π=176π
Answer:
40 more pieces
Step-by-step explanation:
Cody wants to EQUALLY divide 680 candy amongst 45 friends.
That can't be possible because 45 doesn't evenly go into 680. If we do the division, we see:
680/45 = 15.11
So there are some remaining. How many?
45 * 15 = 675
So, the rest are remaining (680 - 675 = 5)
For Cody to equally distribute, he needs how many more? That number should be multiple of 45.
Since 45 * 15 = 675 which is less than 680, to get next number that 45 goes into, we do 45 * 16 = 720
Cody already has 680, he needs 720 altogether for EQUAL SHARE. He would need:
720 - 680 = 40 candy more
Answer:
2.5 miles per minute
Step-by-step explanation:
speed = distance ÷ time
speed = s
distance = 25 miles
time = 10 minutes
s = 25÷10
s = 2.5 miles per minute
