Answer:
Calculated weight of water = 10.01 g
percentage error = 0.1%
Step-by-step explanation:
Given:
Weight of graduate = 35.825 g
Weight of graduate + Water = 45.835 g
Now,
The weight of water = ( Weight of graduate + Water ) - Weight of graduate
or
The weight of water = 45.835 - 35.825
or
The weight of water = 10.01 g
Now,
The percentage of error = 
or
The percentage error = 
or
The percentage error = 0.1%
First, the total difference of the amount of people living in the town from 1998 to 2005 is 7945-5700 or 2245 people. To find out how many years it took for this growth, we would need to subtract 1998 from 2005 to get 7 years. So, in 7 years, the town gained 2245 people. If we divide 2245 by 7 to get the unit rate, we will find that the change in population is 320.71... people per year, or if rounded, 321 people per year, which is a.
Answer: -2
Step-by-step explanation:
The information in the question can be used to form an equation which goes thus:
2nd term = a + d = 4 ...... i
5th term = a + 4d = 22 ....... ii
From equation i
a = 4 - d ........ iii
Put equation iii into ii
a + 4d = 22
(4 - d) + 4d = 22
4 - d + 4d = 22
4 + 3d = 22
3d = 22 - 4
3d = 18
d = 18/3
d = 6
Commons difference is 6
Since a + d = 4
a + 6 = 4
a = 4 - 6
a = -2
The first term is -2
5.76 because the hundredths place is two spaces to the right of the decimal point.
A.120
