The dimensions of a rectangular pool are 24ft long, 16ft wide, and 4ft deep. How much water is needed to fill the pool?

Please help. Marika is training for a race.

Anika [276]

Let's call n the number of days Marika's been training for the race, and $a_n$ the distance she runs on the nth day in meters. After the first day, when n = 1, she runs 100 meters, so

$a_1=100$

On the second day, she runs an additional 4 meters, on the third day, another 4, and so on. Here's what that looks like mathematically:

$a_2=100 + 4\\a_3=100 + 4 + 4\\a_4=100+4+4+4$

It would be easier to write this continued addition as multiplication, in which case those same equations would look like

$a_2 = 100 + 4(1)\\a_3 = 100 + 4(2)\\a_4=100+4(3)$

Notice that, in every case, the number 4 is being multiplied by is 1 less than n. We could even write for our first term that $a_1=100+4(0)$ . In general, we can say that

$a_n=100+4(n-1)$

Which is expressed by option B.

80 units needed 6 units per case<br>

Answer:

First time sending a shipment to Amazon Warehouse here.

I have a question in regards to filling information for my inventory.

I have a total of 20 BOXES ready to be sent. Each individual -BOX- contains 8 smaLL boxes inside. Each smaLL box contains 6 units.

Also, I should specify I’m sending 4 colors, same item. 4 -BOX- red, 4 -BOX- blue, 6 -BOX- steel, 6 -BOX- black. ( 20 BOXES total)

Would you fill it this way:

Review Shipment Contents:

Units Per Case — Number of Cases — Shipped

RED 48 — 4 — 192

BLUE 48 — 4 — 192

STEEL 48 — 6 — 288

BLACK 48 — 6 — 288

---TOTAL UNITS = 960

Shipping Service

SHIPMENT PACKING

ONE SKU PER BOX

SELECT PACK LIST FORMAT

File format Total # of boxes

20 ???

I’m counting Units Per Case as the total number of units in a BOX. And Number of Cases as the number of BOXES. Is this Right?

My confusion is differentiating BOXES and CASES.

I was also thinking about counting Each smaLL box as a Case (Units per Case =6 units) and Number of Cases would be “32”; 4 BOXES of one color , 32 CASES total.

I might be over complicating myself but really need your help on this one so I send the right information to Amazon.

Answer:

#3: 81

Step-by-step explanation:

I haven't done this type of math in a while so I'm unsure about #1 and #2, but #3 is 81.

3^4 = 3 × 3 × 3 × 3

3^4 = 9 × 3 × 3
