In order to keep the rabbits out of the lettuce, Sue is going to put chicken wire around her garden. The diameter of the garden
ANTONII [103]
To keep rabbits away from lettuce garden, she need to set up chicken wire along the garden's circumference. If circumference comes out to be > 20 feet, then yes she will have enough chicken wire to surround the garden. If not , it will be food fest for rabbits. LoL!
Anyways,
Circumference of lettuce garden = pi x diameter of garden

= 3.14 x 6 = 18.84 feet.
Whereas, she has 20 feet of chicken wire.
So she will be left with 1-2 feet of wire.
Better luck for the next time Mr. Bunny :D

What is the solution to this system of equations? 2t + w = 10 4t = 20 − 2w A. It has no solution. B. It has infinite solutions.
joja [24]

Answer:

<h3>B. It has infinite solutions</h3>

Step-by-step explanation:

Given the system of equations:

2t + w = 10 ..... 1

4t = 20 − 2w ... 2

From 1:

w = 10-2t ...3

Substitute 3 into 2 to have;

4t = 20 - 2(10-2t)

4t = 20-20+4t

4t = 4t

Let t = k

Substitute t = k into 1 and get w;

From 1: 2t + w = 10

2k + w =10

w = 10 - 2k

<em>k can take any integers. This shows that the solution to the equation is infinite</em>
