while mrs. poppington was visiting the historic
battleground at gettysburg, she talked with the
landscapers who were replacing the sod in a park near
the visitor center. the part of the lawn being replaced
is shown in the diagram at right. measurements are in
yards. the diagram is not drawn to scale, but all
corners are right angles.

a. use your ruler to make a scale drawing of the lawn that is being replaced. vtilami
let 1 inch equal 1 yard.
(a) - 1 8 1.6
b. how many square yards of sod will be needed?
c.
at $2.43 a square yard, how much will the sod cost?
d.
the area will be surrounded by a temporary fence that costs $0.25 per linear foot
to rent. how many feet will be needed, and how much will it cost?
e. what will be the total cost of materials for the sod and fencing?

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

i think the answer is b

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
