What is multiplication properties. Example a number line that goes from 0-27. Using numbers 6,7,8 and 9.

Answers

They are the commutative, associative, multiplicative identity and distributive properties.

Commutative property: For example 6 * 7 = 7 * 6;

Associative Property: For example (7 * 8) * 9 = 7 * (8 * 9);

Multiplicative Identity Property: For example 6 * 1 = 6 or, 1 * 6 = 6;

Distributive property: For example 6 * ( 7 + 8) = 6 * 7 + 6 * 8 or, ( 7 + 8) * 6 = 7 * 6 + 8 * 6.

If three dozen cookies cost $9, what is the cost per cookie?

Answers

Answer:

$0.25 is the cost per cookie

Step-by-step explanation:

Unit rate defined as the rate are expressed as a quantity as 1 such as 4 meter per second or 4 miles per hour

As per the statement:

If three dozen cookies cost $9.

Use conversion:

1 dozen = 12

then;

3 dozen = 36

then;

36 cookies cost $9.

Cost of cookies = $9

Number of cookies = 36

Then by unit rate definition we have;

$\text{Cost per cookies} = \frac{\text{Cost}}{\text{Number of cookies}} = (9)/(36)$

⇒ $\text{Cost per cookies} = (1)/(4) = \$ 0.25$

Therefore, $0.25 is the cost per cookie

25 cents per cookie

Step-by-step explanation:

Brandon mixed 6.83lb of cashews with 3.57lb of pistacios. after filling up 6 bags that were the same size with the mixture, he hadd 0.35lbof nuts left. what was the weight of each bag?

Answers

The weight of each bag filled by Brandon, is $\fbox{\bf1.675\,lb}$ .

Further explanation:

The amount of cashews and pistachios mixed are $6.83\,lb$ and $3.57\,lb$ respectively then the total weight of mixture is the sum of cashews and pistachios.

After the above nut mixture created by mixing cashews and pistachios is filled in six bags, the weight of remaining nuts is $0.35\,lb$ .

Therefore, the total mixture that is filled in 6 bags is obtained as the difference of total amount and the remaining mixture amount.

$\begin{aligned}{\text{Total mixture filled in six bags}}&=6.83+3.57-0.35\n&=10.4-0.35\n&=10.05\n\end{aligned}$

Now, this obtained amount of mixture weighing $10.05\,lb$ is filled equally in 6 bags as the size of bags is same then the amount of mixture in one bag or each bag is calculated as,

$\begin{aligned}{\text{Total mixture filled in each bags}}&=\frac{{10.05}}{6}\n&=1.675\n\end{aligned}$

Thus, the weight of each of the six bags that Brandon fills, is $\fbox{\bf1.675\,lb}$ .

Grade: Middle school

Subject: Mathematics

Chapter: Mixtures and ratios

Keywords: cashews, pistachios, one bag, six bag, each bag, weight, Brandon, same size, mixture, nuts, 6.83lb, 3.57lb, 0.35lb, total mixture, amount of mixture, remaining amount, remaining weight, total weight, nut mixture.

weight of mixture = 6.83+3.57=10.40lb

amount left= 0.35lb
rest = 10.4-0.35= 10.05lb
rest is filled in 6 bags.
weight in each bag=10.05/6= 1.675lb

hence weight of each bag is 1.675lb
