Answer:

127 1/2 feet

Step-by-step explanation:

A model lighthouse uses a scale of 1/4 inch = 5 feet.

This means that 1/4 inch on the model represents 5 feet in actual life.

The height of the model lighthouse is 6 3/8 inches i.e. 51/8 inches.

The height of the actual lighthouse is:

1/4 inch = 5 feet

51/8 inches = x

Cross-multiply:

51/8 * 5 = 1/4 * x

=> x = 51/8 * 4 * 5

x = 127 1/2 feet

The height of the actual lighthouse is 127 1/2 feet.

Find the midpoint M of the line segment joining the points P= (-7,-8) and Q = (3,2)

Fed [463]

Answer:

(-2, -3)

Step-by-step explanation:

To solve this problem, we use the midpoint formula.

M = $\frac{x1 + x2}{2} , \frac{y1+ y2}{2}$

Plug your coordinates in:

M = $\frac{-7 + 3}{2} , \frac{-8 + 2}{2}$

Simplify:

M = $\frac{-4}{2} , \frac{-6}{2}$

M = (-2,-3)
