Answer:
Step-by-step explanation:
x = large bag, y = small bag
x + y > = 15...thats greater then or equal
4x + 2.5y < = 50....thats less then or equal
======================
he can get 6 lg bags and 10 small bags
You can evaluate all numbers and in the prosses, make any problem easier.
Alright, so uno.
By six types of triangles, I'll assume that your teacher meant acute, right, obtuse, scalene, isosceles, and equilateral.
Some easy things to make with triangles are flags.
You could make a triangular leaf, with triangles as the stem.
Look up animals made out tangram triangles for some inspiration.
Honestly, just do whatever you wanna do.
Answer:
A. 60 feet B. 7200 ft²
Step-by-step explanation:
A. Find the length of the corral along the river that will give the maximum area
To find the length of the corral that will give the maximum area, we differentiate A with respect to x and equate it to zero.
So, dA(x)/dx = d[x(240 - 2x)]/dx
= (240 - 2x)dx/dx + xd(240 -2x)/dx
= 240 - 2x -2x
= 240 - 4x
So, dA(x)/dx = 0
240 - 4x = 0
4x = 240
x = 240/4
x = 60 feet
B. Find the maximum area of the corral
The maximum area at x = 60 feet is
A(x)=x(240−2x)
A(60)=60(240−2(60))
A(60) = 60(240 - 120)
A(60) = 60(120)
A(60) = 7200 ft²
