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.

5/4 is the slope I believe
One day gains 1.1 minutes (11/10)
1.1*8 = 8.8
So I believe it would be 8 minutes and 40 seconds
m∠A + m∠B = 90, since the angles are complementary.
The question also tells us that m∠A = (2x + 10) and m∠B = (-x + 55)
So, all we have to do is input the angle's values into the first equation:
(2x+10) + (-x+55) = 90
Simplify:
x + 65 = 90
x = 25
Input the variable into the angles:
m∠A = 2(25) + 10 = 50 + 10 = <u>60°</u>
m∠B = -25 + 55 = <u>30°</u>
Answer:
x = 6 ,,, 5/9x + 2/3 = 4
Step-by-step explanation:
5x - 8 = 22
5x = 22 + 8
5x = 30
x = 30/5
x = 6
5/9 * 6 + 2/3 =
30/9 + 2/3 =
30/9 + 6/9 =
36/9 =
