If the total of the slices is one cake, and each slice is '<em>s</em>' in size, then you could model an equation like this:
Total (one cake) = 1 slice + 2 slices + 1/5 slices + remaining cake, or
c = 1s + 2s + \frac{1}{5}s + R\\&#10;c=2\frac{1}{5}s+R\\&#10;R=2\frac{1}{5}s -c
Now since I'm sure this question is incomplete, plug in whatever values you need to get the answer.

Alejandra's Tapas Bar offers a menu consisting of $9$ savory and $5$ sweet dishes. You can also get a mix-and-match plate consis
Mariana [72]

Answer:

45

Step-by-step explanation:

Given that the number of savory dishes is 9 and the number of sweet dished is 5.

Denoting all the 9 savory dishes by p_1, p_2,...,p_9, and all the sweet dishes by q_1,q_2,...,q_5.

The possible different mix-and-match plates consisting of two savory dishes are as follows:

There are 9 plates with q_1 from sweet plates which are (q_1, p_1), (q_1, p_2), ..., (q_1,p_9).

There are 9 plates with q_2 from sweet plates which are  (q_2, p_1), (q_2, p_2), ..., (q_2,p_9).

Similarly, there are 9 plated for each q_3, q_4 and q_5.

Hence, the total number of the different mix-and-match plates consisting of two savory dishes

= 9+9+9+9+9= 9\times5=45

Product A is a 12-ounce bottle of generic mouthwash that sells for $1.15. Product B is a 24-ounce bottle of mouthwash that costs
adoni [48]
12 oz = 1.15
24 oz = 2.79
Let's see if 2x12oz is equal, less, or more than the 24oz.
1.15 x 2 = 2.30
2.30<2.79
The 12 oz is a better buy.

Mr.Hoges wants to build a fence around his entire rectangular garden.What is the total distance around his garden
svetoff [14.1K]

Answer:

The total distance of the rectangular garden is the perimeter of the garden.

Step-by-step explanation:

Since the garden is in a rectangular shape. So, the perimeter of the rectangular garden is the distance on which Mr. Hoges can build the fence. However, the perimeter can be determined by adding all the sides. A rectangular shape contains four sides and opposite sides are equal. Thus, it can be determined by using the below formula;

P=2(l+b)

Where

l = length of the garden

b is the breadth of the garden
