The exact value of cos 13pi/8 is

Final answer:

The solution to the problem is obtained by multiplying the number of groups by people per group to calculate used plates, then subtracting this result from the total number of plates to get the unused plates. The answer is 6.

Explanation:

The problem you're dealing with is part of the arithmetic subject in mathematics. The question wants to know the amount of unused plates in a restaurant under certain conditions. You need to multiply the number of groups (9) by the number of people per group (6) to estimate the amount of plates used. So, 9 groups * 6 plates = 54 plates. This is how many plates got used. You then subtract this from the total plates available (60). Therefore, 60 total plates - 54 used plates = 6 unused plates.

Answer:

The possible amounts of vegetables - 2 pounds of carrot and 0 pounds of broccoli, 0 pounds of carrot and 2 pounds of broccoli, 1 pound of carrot and 1 pound of broccoli

Step-by-step explanation:

It is given that,

Ava has already purchased the amount of vegetables given by,

Carrots = 14 pounds

Broccoli = 12 pounds

She needs exactly 2 pounds of the vegetables for the party.

Thus, the possible amount of vegetables she can have is,

Total Pounds                      Carrots (pounds)                Broccoli (pounds)

      2                                        2                                                 0

      2                                        0                                                 2

      2                                        1                                                   1

Answer:

She can add 5/8 pounds of more broccoli and 5/8 pounds of lettuce

Step-by-step explanation:

The problem has errors. The right problem is

Ava needs 2 pounds of vegetables for her party. She already has 1/4 pound of carrots and 1/2 pound of broccoli. Drag weights of vegetables she can add to the vegetables she already has to make exactly 2 pounds.

We know that Ava already as 1/2 pounds of broccoli and 1/4 pounds of carrots, so in total she has

To know how many pounds she needs, we have to find the difference

Therefore, she needs to add 5/4 pounds of another vegetable to make exactly 2 pounds. She can add 5/8 pounds of more broccoli and 5/8 pounds of lettuce

39.6-2.35+1.45=38.70

so basically, you are starting at 39.60

then you go down 2.35 and increase by 1.45

so if you do what I did above, you get $38.70.
