Let x and y be width and length of the plot to be fenced. Therefore,
Area (A) = xy m^2
If the side bordering the river is x, then
Circumference (C) = 8500 = x+2y => x = 8500-2y
Substituting for w in the equation for A;
A = (8500-2y)y = 8500y -2y^2
For maximum area, derivative of A with respect to y is 0. That is;
dA/dy = 0 = 8500 -4y => 4y = 8500 => y = 8500/4 = 2125 m
And, x = 8500-2y = 8500 -2*2125 = 4250 m
Therefore,
One side = 4,250 m and second side = 2,125 m.
Largest area, A = 4250*2125 = 9,031,250 m^2
25$
Step-by-step explanation:
12+12= 24
Nate has one left
12+12+1=25
Answer:
12 meters
Step-by-step explanation:
You have to use the inverse of the pythagorean theorem to do this so you do square root of (20x20-16x16) which is 12
Answer:
<h2>16+x ≤ 26</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
- inequality
- word problems
- creating word probleme
<h3>let's solve:</h3>
so the first condition is
<h3>the maximum number of students in a classroom is 26</h3>
therefore
26 is our subject
and the second condition is
<h3>there are 16 students signed up for the art class</h3>
it means 16 students have already signed up
let's x be more students
therefore
according to the question
the inequality is
<h2>16+x ≤ 26</h2>
