Answer:
3.728 cm²
90
Step-by-step explanation:
To built the envelope I am using a rectangular piece of material 28 m long and 12 m wide.
Out of this material, I have to cut patches that are 1/12 the length and 2/15 the width of the whole material.
So, the length of the patches is
m and the width of the patches is
m.
Therefore, the area of the patches is (1.6 × 2.33) = 3.728 m² each. (Answer)
Now, the area of the rectangular piece of material is (28 × 12) = 336 m²
Hence,
≈ 90 such patches can be made out of the whole material. (Answer)
keeping in mind that parallel lines have the same exact slope, hmmmm what's the slope of the line above anyway?

so we're really looking for the equation of a line whose slope is 1/3 and runs through (18,2)

Horseshoe crabs are marine and brackish water arthropods. They live primarily in and around shallow coastal waters on soft sands.
Answer:
3520.176 feet per minute
Step-by-step explanation:
First, we must convert 40 miles per hour (mph) to miles per minute (mpm):
40 mph = 40 miles/hour / 60 minutes/hour = 0.6667 miles per minute
Next, we convert miles per minute to feet per minute by multiplying 5280 ft per mile:
0.6667 mpm = 0.6667 miles/minute * 5280 ft/mile = 3520.176 feet per minute
