Using the perimeter of the rectangle, it is found that she should buy at most 16 plants.
---------------------------
The perimeter of a rectangle of length l and width w is given by:

In this question, the perimeter is of 1 ft by 4.5, thus,
, and the perimeter is:

- Perimeter of 11 ft.
- The plants will be at least 8 inches = 2/3 feet apart along the perimeter, thus:
1 plant - 2/3 ft
x plants - 11 ft
Applying cross multiplication:




At least 8 inches apart(can be more), thus she should buy at most 16 plants.

Answer:
4 : 7
Step-by-step explanation:
No. of families = 2400
No. of cars = 4200
Family : Cars
= 2400 : 4200
= 24 : 42
= 6 x 4 : 6 x 7
= 4 : 7
A=p (1+rt)
A future value ?
p Principle 900
R interest rate 0.06
T time 9/12
A=900×(1+0.06×(9÷12))
A=940.5
divide total ounces by the amount each cup can hold
678 / 8 = 84.75
so they can fill 84 cups
To find the speed you must write S= d/t so for the first one we will chang 15 m to b so it is = 0.25h so s=3/0.25h = 12km/h an why secand is 45 m to h = 0.75h so S=d/t S =12/0.75 =16 km/h the to find the totel speed we should + the speed together so 12 + 16 = 28 km/h
