Question Help
An architect makes a model of a new house. The model shows a tile patio in the backyard. In the
model, each tile has length in. and width = in. The actual tiles have length 5 ft and width a ft.
What is the ratio of the length of a tile in the model to the length of an actual tile? What is the ratio of
the area of a tile in the model to the area of an actual tile? Use pencil and paper. Describe two ways
to find each ratio.

answer: 4/6 =5/7.5

step-by-step explanation: it is based on scale and the scale between the two is 1.25. the answer is correct but i dont know if i explained it right

answer: jasmine will bake 4/3 or 1 1/3 cookies in an hour

if u add 1/3 every 15 minutes after an hour u will have 4/3 or 1 1/3

i think it is c, not positive though

step-by-step explanation:

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.
