Answer:
19,8
105,7
144,84
304
Step-by-step explanation:
At first, 9) is not correct.
Formula for surface of parallelogram is
A=a*H
DONt divide with 2.
So the 9) is 19.8
10) A=15.1*7=105.7
11) A=14.2*10.2=144.84
12) A=20*15.2=304
Answer: 12.6 inches
Step-by-step explanation:
From the question, we are told that the average annual precipitation in Berkeley, CA is 26.8 inches and that of Albany, NY is 39.4 inches.
The difference in the two cities average annual precipitation will be:
= 39.4 - 26.8
= 12.6 inches
-20+15+30+-45=-20
-20/4=-5
The average is -5
