A farmer is putting up a fence for her animals. She orginally had the fence enclosing a square was 18ft by 18ft. Suppose she uses the same amount of fencing to enclose a circular area. What is the area of the circle?
Answers
First look: More than 324 square feet :) Now, which means that . But l is the original perimeter, 4 times the side of the square, that is, 72 ft. So, Now, the area of that circle is , which is about 412.5 square feet. It's true, that's more (that's the most you can actually get with that amount of fence :) )
Trevor paints 1/6 of the fence surrounding his farm each day. How many days will it take him to paint 3/4 of the fence?
Answers
To do this you have to divide 3/4 by 1/6. To do this multiply 3/4 by the reciprocal of 1/6. The reciprocal of 1/6 is 6/1. So you have to multiply 3/4 and 6/1. This will give you 18/4. You now simplify it to 4 2/4, which can be simplified even more to 4 1/2. It will take Trevor 4 1/2 days to paint 3/4 of the fence. BTW- In case you are wondering how long it'll would take him to paint the entire fence, it would be 6 days.
What are the coordinates of point H?
Answers
Real simple...
let's go step-by-step...
you know..that to find the coordinates of a point..you first go to the
x-axis...
move over..and find where point H is at..it's at -1.5..
Then..move up to find where it's located on the
y-axis..
move up and see it's at 3
Thus, the coordinates..(-1.5,3)
(x,y) x means how many units right from the center the points is (if it is to the left of center, say it is negative units)
y means how many units up from center the point is (if it is under center, say it is negative)
it is to th eleft and above center (-,+) count how far to the right -1.5 units to right
how far up 3 unit sup (-1.5,3)

Jack got the expression 7x + 1 and then wrote his answer as 1 + 7x. Is his answer an equivalent expression? How do u know? Explain using extended vocabulary
Answers
Yes, it is an equivalent expression because even though you move two pieces of an equation it will still equal the same thing, unless there are parentheses involved.
