Answer:
b will be the right answer
I am sure
Area=l*b=l*(l-2)=80(given)
so, l^2 - 2l =80
l^2 - 2l - 80=0
l=10 or -8
l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36
Answer: 25
Step-by-step explanation:
From the question, we are informed that the piece of rural land sold ten years ago for 40000 and that the price for the same land this year is $800 more per acre, and it sold for 60000.
The size of the piece of land in acres will then be:
40000 + 800x = 60000
800x = 60000 - 40000
800x = 20000
x = 20000/800
x = 25
The land is 25 acres
Answer:
Yes, this is true.
Step-by-step explanation:
Given is :
50 workers each worked 8 hours a day.
Combined total is = 
hours
Journey Motorcycles produced 100 motorcycles.
So, their productivity is :
This can be simplified as 1 motorcycle per 4 hours.
So, the given statement is true.
We need to compute 5% out of $60K.
Tax: 5%×60000=5/100×60000=5×600=$3000
Answer: $3000
