Answer:
Option B. 24 horses and 50 humans
Step-by-step explanation:
Let
x ----> the number of humans
y ----> the number of horses
Remember that
A human has one head and two legs
A horse has one head and four legs
so
----> equation A
-----> equation B
Solve the system by graphing
The solution of the system is the intersection point both graphs
The solution is the point (50,24)
see the attached figure
therefore
The number of humans is 50 and the number of horses is 24
54 = t + 9 this is your equation!
Answer:
Steve should use:
- 8.53 Inch of Wire to make the circle
- 43.47 Inches of Wire to make the Square.
Step-by-step explanation:
Let Steve cut the wire so that the first piece has length x.
Therefore, the second piece will have a length of (52 - x).
The wire of length x is used to make a circle
Circumference of a Circle,


The wire of length (52-x) is used to make a square.


Total Area = Area of Circle + Area of Square

Let us simplify the expression

This is the function of a parabola which opens up.
To find where A is minimum, find the axis of symmetry.


Steve should cut the wire so that the length of wire used to make a circle is 8.53 Inches.
Length of wire used to make the square =52-8.53=43.47 Inches
You do:
130+x+5=180
x+135=180
x=45
