Answer:
water reflects 5.6 times as many uv rays as sand
------------------------
Step-by-step explanation:
sand: 0.15
water: 21/25 --> 0.84
0.84/0.15= 5.6
therefore, water reflects 5.6 times as many uv rays as sand
30 feet
Step-by-step explanation:
- Since Natalie is standing right next to the Penthouse, we can establish the ration between her height and the shadow she casts, which is;
1.1 : 5.5
- The two are related by a factor of 1/5
- We can use this factor to establish the shadow cast by the penthouse;
1/5 * 150
= 30

so it would be 40/20.80=52
so it is c.52 pre Oz
We are given three vertices, but we do not know which two are adjacent. We could draw these points to find out. But that is not neccesary.
In a parallelogram we can draw four types of lines. Two types are sides and two types are diagonals. Diagonals are lngre than sides. This helps us to solve this problems. If we find distance between all points we will take only two smaller numbers because they represent sides.
Distance between two points is given by:
For points (3,2) and (4,4) distance is:
For points (3,2) and (6,1) distance is:
For points (4,4) and (6,1) distance is:
Last distance is greatest and it represents a diagonal. Other two distances represent sides.
Perimeter of a parallelogram is given by:
Since the distance is 3.667km and the time is 1/3 of an hour (20 minutes) we take the distance and divide it with time 3.667/20 thus the answer is
0.183 km/hr
