Length = 5x
width = x
area = 125
A = L*W
125 = (5x)(x)
125 = 5x^2
125/5 = x^2
25 = x^2
sqrt{25} = sqrt{x^2}
5 = x
The width is 5 feet.
The length is 5 times 5 feet or 25 feet.
To find the perimeter, we use P = 2L + 2W.
P = 2(25) + 2(5)
P = 50 + 10
P = 60 feet.
Done!
Answer:
what
Step-by-step explanation:
Answer:
2/3 hours or 40 mins.
Step-by-step explanation:
No. of trees planted by David = 11
No. of hours worked by David to plant 11 trees = 7 1/3 hours = (7*3 + 1) /3 = 22/3
It takes him about the same amount of time to plant each tree
let time taken to plan 1 tree be x
then time taken to plan 1*11 tree = 11*x
But, given that total time taken is 22/3 hours
thus,
11x = 22/3 hours
x = 22/(3 *11) = 2/3
Thus, it took 2/3 hours to plant each tree.
As 1 hour has 60 minutes
Time taken in minutes to plant 1 tree = 2/3 *60 mins = 40 mins
Answer:
454cm
Step-by-step explanation:
perimeter of rectangle = 2(l+b)=2(1.52+0.75)=4.54meter =4.54*100 cm( 1m =100cm) = 454cm.
In math, slope<span> is the ratio of the vertical and horizontal changes between </span>two points<span>on a surface or a line. The vertical change between </span>two points<span> is called the rise, and the horizontal change is called the run. The </span>slope<span> equals the rise divided by the run: . This simple equation is called the </span>slope formula<span>.</span>
