Given:
The inequality is:

To find:
The negation of the given inequality.
Solution:
The given inequality is
, it means all the value which are greater than 3 are included in the solution set.
Since all the values which are less than or equal 3 are not included in the solution set, therefore the negation of the given inequality is

Therefore, the negation of
is
.

Answer:
1. a. 2,000
2. b. 10 years
3. a. 6.72937
4. d. 9%
Step-by-step explanation:
1. If 58% are boys, the percentage of girls is:
= 100 - 58
= 42%
That means 840 is 42% of the students in class. The students in class are therefore:
= 840 / 42%
= 2,000 students
2. If Birr 300 is invested at 6% per year, the amount in interest it earns per year is:
= 300 * 6%
= Birr 18
To get to Birr 180, it would take:
= 180/18
= 10 years
3. When a number is in percentage that means that it is a fraction with the denominator being 100. The number is decimal will therefore be it divided by 100:
= 672.937/100
= 6.72937
4. The investment accrued Birr 12 out of Birr 400 in 4 months. This means that it increased by:
= 12/400
= 3%
A year can be divided into three by 4 months. This means that the yearly rate is therefore:
= 3% * 3
= 9%
Answer:

Step-by-step explanation:
''Vedavit walks his dog the same distance each day.''
After 5 days,he has walked his dog 1 mile.''
First we are going to convert the total distance (1 mi) to feet.
The relation is :

After 5 days, he has walked his dog 5280 ft.
The next step is to divide the total distance for the amount of day that he has walked his dog (we do this because Vedavit walks his dog the same distance each day)

Finally, he has walked his dog
each day
Answer:
20 feet per second
Step-by-step explanation:
130/6.5 = 20
