Answer:

Option C. $0.3

Step-by-step explanation:

Samantha is buying ink pens.

The price of a 10-pack pens  = $9.00

Unit price of one pen = \frac{9}{10} = $0.9

The price of 5-pack pens = $6.00

Each pen cost = \frac{6}{5} = $1.20

The difference of the unit price of one pen for each pack = 1.20 - 0.9 = $0.3

Option C. $0.3 would be the answer.

Find the dimensions of a deck which will have railings on only three sides. There is 28 m of railing available and the deck must
Roman55 [17]

Answer:

The largest possible area of the deck is 87.11 m² with dimensions;

Width = 9.33 m

Breadth = 9.33 m

Step-by-step explanation:

The area of a given dimension increases as the dimension covers more equidistant dimension from the center, which gives the quadrilateral with largest dimension being that of a square

Given that the railings will be placed on three sides only and the third side will cornered or left open, such that the given length of railing can be shared into three rather than four to increase the area

The length of the given railing = 28 m

The sides of the formed square area by sharing the railing into three while the fourth side is left open are then equal to 28/3 each

The area of a square of side s = s²

The largest possible area of the deck = (28/3)² = 784/9 = 87.11 m² with dimensions;

Width = 28/3 m = 9.33 m

Breadth = 28/3 m = 9.33 m.

Lois says any addition equation where the addends are all the same can be written as a multiplication equation. Is Lois correct
USPshnik [31]
Lois is correct. This is because multiplication is repeated addition. It means that when your addends are just the same number but added several times, the sum is just equivalent to the product of that number times the number of times it was added. For example, 4+4+4 = 4×3 = 12.

The double number line shows that 444 bottles of water cost 101010 dollars at a music festival. Based on the ratio shown in the
MrRissso [65]

Answer:

Please see the attachment for double number line.

Explanation:

We are given cost of 4 water bottles is $10

We can write ,

Cost of 4 bottles = $10

Cost of 1 bottle = $2.5

Cost of 2 bottles =$5

Cost of 3 bottles = 3\times 2.5 = $7.5

Cost of n bottles = $2.5n

Now we draw the double number line.

Bottom line(Line 1)  will take as number of bottles:  

1   2   3   4   5   6  

Above line (Line 2) will show the cost of corresponding number of bottles:

2.5  5  7.5  10  12.5  15
