For a birthday party you need to cut two submarine sandwiches into smaller pieces of equal length for your friends.one sandwich
vovangra [49]

Answer:

4 inches

Step-by-step explanation:

Let us assume that there are few numbers of friends.

Therefore, 28 inches of one sandwich has to be divided into equal few pieces and another 36 inches of the sandwich has to be divided into equal few pieces.

We have to calculate the greatest possible length of the pieces.

Therefore, the greatest length of each piece will be a common factor of 28 and 36.  

Now, we have 28 =2×2×7 and 36 =2×2×3×3. Hence, the greatest possible factor is 2×2 = 4.

Therefore, greatest possible length of each piece of the sandwich is 4 inches. (Answer)

Kelly signed copies of her new book at a local book store. He had budgeted 1.15 per student. It turned out that he spent 0.25 le
PolarNik [594]

Answer:

$27

Step-by-step explanation:

In this question, we are asked to calculate how much spent on some number of students in a bookstore where books were being signed by an author. We proceed as follows:

To calculate the amount she budgeted, there are different approach we can take. We can calculate the amount she has to pay for the signing at the old price. Then, we calculate the amount of money she has to pay on discounting the fees. We then subtract the values to arrive at the total value she has spent.

Firstly, we calculate the total amount of money to be spent on the students based on his budget. He had budgeted 1.15, then the total amount budgeted would be 30 * 1.15 = $34.5

Now we are made to know that she spent 0.25 less. Thus, the total amount spent less would be 30 * 0.25 = $7.5

The actual amount thus spent is $34.5 - $7.5 = $27

He spent a total of $27 on 30 students
