Total Weight = Weight of the book + Weight of the CD + Weight of the box

Total Weight = 1 1/4 pound + 1/5 pound + 3/10 pound

Total Weight = 5/4 + 1/5 + 3/10

To add these fractions, you need to put them over a common denominator. To do that, find the least common multiple of 4, 5, and 10. Below is a table of the multiples. The least multiple they have in common is 20, shown in orange. So use 20 as your least common denominator.

1 2 3 4 5 6 7

4 x 4 8 12 16 20 24 ...

5 x 5 10 15 20 25 30 ...

10 x 10 20 30 40 50 60 ...

<h2>Answer:</h2>

<h2>Step-by-step explanation:</h2>

Cost per Packet * Number of Packets + Shipping = Amount to Spend

0.90 * b + 2.50 = A

You can spend a maximum of $18.50

A < 18.50

Rearrange the formula to find b

Number of Packets = Amount to Spend - Shipping / Cost per Packet

18.50 - 2.50 = 16.00 / 0.9 = 17.7...

You can't have 0.7 of a packet so you have to round down to 17.

Now if you put it into the original formula:

0.90 * 17 + 2.50 = 17.80

And 17.80 is less than 18.50.

When two dice are rolled, what is the probability the two numbers will have a sum of 10

AlekseyPX

Answer:

The correct answer is option C. 1/12

Step-by-step explanation:

It is given that, two dies are rolled.

The outcomes of tossing two dies are,

(1,1), (1,2), (1,3), (1,4), (15), (1,6)

----- -------- ------ ------ ----- ----

(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)

Number of possible outcomes = 36

<u>To find the probability</u>

The possible outcomes are getting sum 10 which are,

(4,6), (5, 5) and (6,4)

Number of possible outcomes = 3

Therefore probability of getting sum 10 = 3/36 = 1/12

The correct answer is option C. 1/12
