Answer:
a) 675 000
b) 685 000
Step-by-step explanation:
The population of a town is 680 000 correct to the nearest 10 000.
a) To find it lower bound, we level of accuracy by 2 and then subtract from 680 000
The lower bound is:
680 000-5000=675,000
Therefore the least possible population of the town is 675 000
b) We repeat the same process to find the upper bound
680 000+5000=685,000

Where is the question?
Step-by-step explanation:
Answer:
No solutions.
Step-by-step explanation:
x - y = 2 <Start with an equation
x - (x + 2) = 2 <Plug in the given y value and solve for x
x - x - 2 = 2 <Combine like terms
0 - 2 = 2 <There are no values of x
No solutions.
0.75 kilometers per minute.. & 3.75 kilometers in 5 mins ....... im 100%
Let L = length & W= width
Just rewrite the problem in math:
L=5+2W & Area = L x W=403cm²===> (5+2W).(W)=403.
==>2W²+5W-403 =0 Solve the quadratic equation. & you will get W=13
Plug it to find L =31
