Answer:

0.8594 in/hr

Step-by-step explanation:

Decreased in the water level is 8.25 in.

Time 11 P.M. and 8:36 A.M.  is 9 hr 36 min = 9.6 hr.

The rate of decreasing water level is constant.

So, \text{Rate}=\frac{\text{Level decreased}}{\text{Time taken}}

\Rightarrow \text{Rate}=\frac{8.25}{9.6}=0.8594 in/hr.

Hence, the water level drop at the rate of 0.8594 in/hr.

What is the measure of the angle in the Southwest corner of the intersection of broadway and 22nd street
Svetllana [295]

Answer:

  105°

Step-by-step explanation:

Maps are usually oriented so that North is up. That means the southwest corner is below and to the left of the intersecting lines. Since numbered streets are usually parallel, we're to assume that W 22nd street is parallel to W 20th street. That makes Broadway a transversal of parallel lines, and it makes the angle of interest a corresponding angle to the one whose measure is shown.

In this (assumed) geometry, corresponding angles are congruent, so the angle of interest has measure 105°.

Answer:

Lara's average speed :

average speed = total distance / total time

                         => 8 miles / 2.5 hours

                         => 3.2 mph

Tim's average speed :

= total distance / total time

= 12 miles / 3.5 hours

= 3.43 mph

therefore,

Tim's average speed (3.43 mph) is greater.
