Answer:

One will save $.0.60 with baker’s dozen option.

Step-by-step explanation:

Number of rolls: 6                8                Baker’s dozen

Price ($):            $3.60        $4.80            $7.20

At $3.60, we have 6 rolls, so per roll cost is = \frac{3.60}{6} = $0.60

At $4.80, we have 8 rolls, so per roll cost is = \frac{4.80}{8} = $0.60

Now, a baker’s dozen includes 13 rolls for the price of a dozen rolls.

This means, instead of 12 rolls you will get 13 rolls at $0.60 per roll.

Hence, one will save $.0.60 with baker’s dozen option.

The rolls are $3.60 for 6 rolls, or $0.60 each, so saving the cost of the 13th roll saves you $0.60.

Which transformation moves all points the same distance in the same direction?
Lesechka [4]

Answer:

In a translation, ALL of the points move the same distance in the same direction. A translation is called a rigid transformation or isometry because the image is the same size and shape as the pre-image.

What is the least positive integer divisible by the numbers 2, 4, and 7?
Viefleur [7K]

Answer:

Least positive integer divisible by the numbers 2, 4, and 7 is  28

Step-by-step explanation:

We can find the least positive integer divisible by the numbers 2, 4, and 7 by taking the LCM

First lets List all prime factors for each number.

Prime Factorization of 2

2 is prime  =>  2^1

Prime Factorization of 4 is:

2 x 2  =>  2^2

Prime Factorization of 7 is:

7 is prime  => 7^1

For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.

The new superset list is

2, 2, 7

Multiply these factors together to find the LCM.

LCM = 2 x 2 x 7 = 28
