Answer:
<u>Valterri's unit rate for Day 1 in minutes per lap is 3.5 or 3 minutes and 30 seconds.</u>
Step-by-step explanation:
Let's find Valterri's unit rate for Day 1 in minutes per lap, this way:
Total time = 1 hour, 13 minutes, and 30 seconds
Total time = 60 minutes + 13 minutes + 30 seconds
Total time = 73 minutes and 30 seconds
Total time = 73.5 minutes (30 seconds = 0.5 minutes)
Number of laps = 21
Valterri's unit rate for Day 1 in minutes per lap = Total time/Number of laps
Valterri's unit rate for Day 1 in minutes per lap = 73.5/21
<u>Valterri's unit rate for Day 1 in minutes per lap = 3.5</u>
Answer:
-2x + 6
Step-by-step explanation:
Step 1: Define
f(x) = 3x + 2
g(x) = 4 - 5x
Step 2: Find f(x) + g(x)
3x + 2 + 4 - 5x
-2x + 6
The leash will serve as the radius of the circle that Adrianne's dog will be running around on.
radius = 9 feet long
Area = π r²
Area = π (9ft)²
Area = π 81ft²
Circumference = 2 π r
Circumference = 2 π 9ft
Circumference = 18ft π
The circumference of the circle that the dog will be forming when it runs around his leash is 18ftπ and the area it will cover will be 81ft²π.
Answer: I cant see the full question but I would say figure D
Step-by-step explanation:
30/20 in half is 15/10
also between 12/8 and 18/12 is 15/10
