The square pyramid below represents a tent that Wayne is making.

The sides of the tent will be covered in blue fabric, and the base of the tent will be covered in brown fabric.

Find the surface area that will be covered in each color of fabric.

Enter your answers in the boxes.

Answers

Answer:

79

Step-by-step explanation:

The answer is 27 m² and 9 m² of blue and brown fabric will be used respectively.

What is a square pyramid structure

A square pyramid is a three-dimensional shape that has a total of four triangular faces.  

A most famous example of such a pyramid in real life is the Great Pyramid of Giza.

The sides are triangular faces are 3 m and 4.5m

Height of the prism is 4.5m and the side of the square base is 3m

The surface area for triangular face is (1/2) *  base * height

= (1/2) * 3 * 4.5

= 6.75 m²

For four faces the surface area of the blue fabric required is side * side

= 4 * 6.75

= 27 m²

For the base , brown fabric is being used and the surface area of the base is

= 3 * 3

= 9 m²

Therefore 27 m² and 9 m² of blue and brown fabric will be used respectively.

N a typical 2-pound bag of M&Ms contains 500 individual pieces, of which... 120 are blue, 70 are brown, 80 are green, 100 are orange, 60 are red, and 70 are yellow. If I randomly select one M&M candy from the bag, what is the probability that candy will be red?

Answers

Answer:

0.12

Step-by-step explanation:

Number of red candies = 60

Total number of candies = 500

Recall :

Probability of event A = number of occurrences of A / total number of occurences

= required outcome / Total possible outcomes

The probability of randomly selecting a red candy is :

= number of red candies / total number of candies

= 60 / 500

= 0.12

Answers

Answer: w = 2x + 4

Step-by-step explanation: The rabbit started at 4 ounces, and gained two each week.

Week 0 = 2(0) + 4 = 4

Week 1 = 2(1) + 4 = 6

Week 2 = 2(2) + 4 = 8

Write 3-5 sentences about the process of the Sums and differences of cubes Factoring Method

Answers

Answer:

nah nah mane 12

Step-by-step explanation:

Answer:

Step one: Decide if the two terms have anything in common, called the greatest common factor or GCF. If so, factor out the GCF. Do not forget to include the GCF as part of your final answer. In this case, the two terms only have a 1 in common which is of no help.

Step 2: Rewrite the original problem as a difference of two perfect cubes.

Step 3a: “Write What You See” If you disregard the parenthesis and the cubes in step 2, you should see:

Step 3b: “Square-Multiply-Square” If you square the first term, x, you get x2. If you multiply the two terms, x and 4, you get 4x. Finally, if you square the second term, 4, you get 16.

Step 3c: “Same, Different. End on a Positive” This will determine the signs of the problem. The first sign should be the same as the original question, the next sign should be different then the first, and the last sign should always be positive.

Step 4: Write the final answer.
