Answer:

110/289 feet

Step-by-step explanation:

Step one:

given data

Area of the floor= 55/14 square feet.

The length of the floor= 8 1/2 feet-----convert to simple fraction= 17/2 feet

Step two:

The expression for the area of the room is

Area= L*W

55/14= 17/2*W

55/14=17W/2

cross multiply

17W*14=55*2

289W=110

divide both sides by 289

W= 110/289 feet

Across which axis was point A reflected​
Snezhnost [94]

Answer:

When point A with coordinates (0, -1) is reflected across the x-axis and mapped onto point A', the coordinates of A' will be (0, 1).

i.e A'(0, 1) is the image of point A after a reflection.

Hence, point A is reflected across the x-axis.

Step-by-step explanation:

When we reflect a point A across the x-axis, the value of 'y' gets negated, but the value of 'x' remains unchanged.

In other words, when point P with coordinates (x, y) is reflected across the x-axis and mapped onto point P', the coordinates of P' will be (x, -y).

Thus, the rule is:

P(x, y) → P'(x, -y)

Thus, when point A with coordinates (0, -1) is reflected across the x-axis and mapped onto point A', the coordinates of A' will be (0, 1).

i.e A'(0, 1) is the image of point A after a reflection.

Hence, point A is reflected across the x-axis.
