Answer: 17.14 ft
<u>Step-by-step explanation:</u>
The area of the flower bed is 60 ft x 80 ft = 4800 ft²
The perimeter of the sidewalk that surrounds the flower bed is:
- 2(60 ft) + 2(80 ft)
- = 120 ft + 160 ft
- = 280 ft
The area of the sidewalk is:
area of sidewalk = area of flower bed
280w = 4800
≈ 17.14
The slope of the line would be -1/2.
To find the slope we need to make the line in the form y = mx + b:
2x + 4y + 7 = 0
2x + 4y = -7
4y = -2x - 7
÷ 4
y = (-2/4)x - (7/4)
-2/4 simplifies to -1/2.
I hope this helps!
Answer:
15.2%
Step-by-step explanation:
There are 12 marbles in total and there are 5 red marbles, so the probability of getting a red marble is 5/12. There are now 11 marbles and there are 4 blue marbles. So the probability of getting a blue marble is 4/11.
You multiply these 2 values together.
5/12 * 4/11 = 20/132 = 0.1515
This is about 15.2%
