What is the surface area of a square prism with a side measure of 15

Answers

Answer 1

Answer: 1,350 <--- answer

to find the area of the surface of one side, you would do length times width.
length is 15
width is 15
15 x 15 is 225
since there are 6 sides, you multiply that by 6
225x6 is 1350 which is the answer

Answer 2

Answer: L x W = Area it is SQUARE prism
15 x 15 = 225²
225 x 6 = 1350
1350 is the Surface Area :)

A company has a $150 budget to provide lunch for its 20 employees. The options are to provide either roast beef sandwiches, which cost $5 apiece, or tuna sandwiches, which also cost $5 apiece. The company also wants to use the entire budget. Suppose r represents the number of roast beef sandwiches it provides and t represents the number of tuna sandwiches. Which statement is correct?

Answers

I don't know your options, but here are some facts:
-all their options are sandwiches, and they all cost 5 dollars.

-This means that they can buy 150/5=30 sandwiches. This will make them use the entire budget!

-I would suggest cutting the sandwiches in half, then everyone gets three halves!

and if you say r for roast beef and t for tuna, you can write:

r+t=30.

and you can distribute is freely as long as both are 0 or bigger and their sum is 30!

Answer:

D.The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r + t = 20 and 5 r + 5 t = 150.

Step-by-step explanation:

Solve the system. x - 3y = -6 and 2x + 3y = -3

Answers

Answer:

1. x = -3y - 6

2. x = (-3y - 3)/2

Step-by-step explanation:

To get x on its own, we have to add 3y to both sides. We have x = -3y - 6. For the next one, we also want to isolate the variable. So we subtract 3y and we end up with 2x = -3y - 3. Then we divide both sides by 2 and we have our answer. I hope this helps because I didn't really understand the question...

joyce is helping her aunt create craft kits. her aunt has 138 pipe cleaners, and each kit will include 6 pipe cleaners. what is the total number of craft kits they can make?

Answers

23 pipe cleaners cause 23 x 6= 138

The total number of craft kits they can make is: 138 pipe cleaners can make 23 kit

Further explanation

Crafting is a fun and productive hobby for people of all ages. Crafting is therapeutic also. To get started, find the things in your house that are just sitting around gathering dust. For example, you can spray paint an old glass jar to make it into a modern vase.

The following are examples of craft industry: Artisanal Foods, Baked Goods. Small scale bakeries are a craft industry, Craft Beer, Fashion, Textiles, Traditional Clothing, Jewelry, and Decorative Arts.

Number of pipe cleaners needed for 1 kit is 6 (Given)

The number of kits that can be made from 138 pipe cleaners:

Total pipe cleaners = 138

Number of pipe cleaners in each kit = 6

6 pipe cleaners = 1 kit, so

1 pipe cleaner = $(1)/(6)$ kit

138 pipe cleaners = $(1)/(6) * 138$ kit

138 pipe cleaners = 23 kit

Therefore 138 pipe cleaners can make 23 kit
