24 x 12 1/2 x 12 3/4 what is the volume of the fish tank
hjlf

Answer:

The volume is 3825 cubic units

Step-by-step explanation:

To find the volume of the fish tank multiply out the dimensions.

We were given the dimensions as:

24 \times 12 \frac{1}{2}  \times 12 \frac{3}{4}

Change the numbers to improper fractions

24 \times  \frac{25}{2}  \times \frac{51}{4}

We cancel out to get

3 \times 25 \times 51

After a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are A'(6,3), B'(-2, 1)
Fed [463]

Answer:

  • A(3, -6)
  • B(1, 2)
  • C(7, -1)

Step-by-step explanation:

Rotation by -90° about the origin is the transformation ...

  (x, y) ⇒ (y, -x)

So, your pre-image points are ...

  A'(6, 3) ⇒ A(3, -6)

  B'(-2, 1) ⇒ B(1, 2)

  C'(1, 7) ⇒ C(7, -1)
