Okay. So, we should convert fractions to the least common denominator, which is 20. That would be 2 5/20 and 2 16/20. Add both of those numbers up to get 5 1/20. Taylor ran and walked 5 1/20 miles.
Answer:
The space between the plants is approximately 1.26ft
Step-by-step explanation:
Given
Circular Garden
Number of plants = 20
Diameter of garden = 8ft
First, the circumference of the garden needs to be calculated; This is so because the plants that will be placed at the edge of the garden will occupy the circumference of the circle.
Calculating the circumference....
Circumference = 2πr
Where r = radius
r = ½ * diameter.
r = ½ * 8ft
r = 4ft
So,
Circumference = 2π * 4
Circumference = 8π ft
Given that the plants will be spaced evenly.
The distance between them = Circumference ÷ Number of plants
Distance = 8π/20
Distance = 0.4π ft.
Solving further to get actual distance (take π as 22/7)
Distance = 0.4 * 22/7
Distance = 8.8/7
Distance = 1.2571428571 ft
Distance = 1.26ft (Approximated)
Hence, the space between the plants is approximately 1.26ft
I would say 64 if they are in a straight line since both sides have 6x8 and 2x8 you can add those to get 8x8=64
Answer:
1 . -2 and 7. 2.-6 and 3 i think
Step-by-step explanation:
After one half life it i s 130/2 = 65 g
after another 2 half lives it will be 65*1/2^2 = 16g to nearest gram
