Answer:
I don't understand what you're asking. can you put a question on this?
3x+12=5x-21
-5x -5x
-2x + 12 = -21
-12 -12
-2x=-33
x = 16.5
A decimeter is a tenth of a centimeter.
So, divide/multiply: 2 ÷ 0.1 = 20 <em>or</em> 2 × 10 = 20
So, the picnic bench is <em>20 decimeters long.</em>
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
