Step-by-step explanation:

Alright, so we know that they can unload 25 trucks in 5 hours.

If we do 25/5 We find out that they can unload 5 trucks per hour

Unfortunately, that is not one of the answers, so we will have to do some investigating to find something that is equivalent!

After evaluating the available answers, you can find that answer D lines up with our first assumption!

Every 1/5th of an hour the Fast-Pack people can unload a truck!

We can calculate this by writing:

1/5*25=5

Please let me know if you have any confusion! :)

Hansika paid $9.25 for 2.8 pounds of pretzels. About how much did she pay for a pound of pretzels?

NeX [460]

Answer: $3.30

Explanation:
You set up a proportion where

9.25 X
------ = -----
2.8 1

Then you cross multiply and see that...
2.8X = 9.25
Then X = 9.25 / 2.8 = 3.30

Given the sequence 8, 16, 32, 64, ..., which expression would give the thirteenth term?

mrs_skeptik [129]

8, 16, 32, 64,…
×2 ×2 ×2

$a_{n} = a_{1} * r^{n - 1}$
$a_{n} = 8 * 2^{13 - 1}$
$a_{n} = 8 * 2^{12}$
$a_{n} = 8 * 4096$
$a_{n} = 32768$

   First Term: 8
      Second Term: 16
      Third Term: 32
      Fourth Term: 64
       Fifth Term: 128
      Sixth Term: 256
   Seventh Term: 512
   Eighth Term: 1024
   Ninth Term: 2048
      Tenth Term: 4096
   Eleventh Term: 8192
   Twelfth Term: 16384
Thirteenth Term: 32768

$The\ expression\ that\ would\ give\ the\ thirteenth\ term\ of\ the\ problem\ would\ be\ the\ equation\ of\ the\ geometric\ sequence,\ which\ is\ equal\ to\ a_{n} = a_{1} * r^{n - 1}.$

How do I do #12? Please show all work. Please help!

hammer [34]

You have the ratio set up correctly:

2x+2/12 = x+3/21

Now cross multiply:

2x+2 * 12 = x+3 * 21

Simplify:

24x + 24 = 21x + 63

Subtract 24 from each side:

24x = 21x + 39

Subtract 21x from each side:

3x = 39

Divide both sides by 3:

x = 39/3

x = 13
