Answer:

\Large \boxed{\frac{1}{15} }

Step-by-step explanation:

The two-digit perfect squares are 16, 25, 36, 49, 64, 81.

There are 6 numbers that are two-digit perfect squares.

There are a total of 90 numbers that have two-digits.

P(two-digit perfect square) = \frac{6}{90} =\frac{1}{15}

Bingel [31]

Perimeter of window is 192 inches.

Step-by-step explanation:

We are given:

Area of rectangular window = 2160 inches square

Length of rectangular window = 60 inches

Required:

Perimeter of window=?

Formula to find Perimeter is:

Perimeter=2(length+Width)

We first find width of rectangular window by using formula of area:

Area=Length*Width

Putting values:

Area=Length*Width\\2160=60*Width\\Width=\frac{2160}{60}\\Width=36\,\,inches

So, width = 36 inches

Now finding perimeter:

Perimeter=2(length+Width)\\Perimeter=2(60+36)\\Perimeter=2(96)\\Perimeter=192\,\,inches

So, perimeter of window is 192 inches.

Kruka [31]

Answer:

A

Step-by-step explanation:

Construct a perpendicular bisector of segment AB.

Perpendicular bisector is a line that divides the line into two equal halves forming 90° at the intersection point.

So, points A and B will be at the same distance from the intersection point.

If the constructed line (perpendicular bisector) is the reflection axis, then point B will be the refection point of A.
