Julian jogs 2 kilometers east, 4 kilometers north, and then 7 kilometers west. How far is Julian from his starting position, to the nearest tenth of a kilometer?

Answers

Answer 1
Answer:

Answer:

6.4 kilometer

==============================

Step-by-step explanation:

See the attached figure.

Let Julian starts from point O (0,0)

Julian jogs 2 kilometers east ⇒ arrived to point A (2,0)

4 kilometers north ⇒ arrived to point B (2,4)

and then 7 kilometers west ⇒ arrived to point C (-5,4)

How far is Julian from his starting position?

So, it is required to find the distance OC

From the graph OC = √((-5)^2+(4)^2)=√(25+16)  =√(41) =6.403

So, the distance from his starting position ≈ 6.4 km (to the nearest tenth of a kilometer)

of the 95 children in 6th grade 3/5 went to holiday parties how many students went to holiday parties in all

Answers

The best thing to do firstly is to find out what 1/5 of 95 is.
You have to divide 95 by 5.
95/5= 19
Therefore, 1/5 of the children is 19.
As you're looking for 3/5, you have to multiply 19 by 3
19*3= 57
Therefore, 57 of the students went to holiday parties
Hope this helps :)
In this question, there are several information's of immense importance. Based on these information's, it is easy to get to the required answer. There are 95 children in 6th grade and out of them 3/5th went to holiday parties.
Then
Number of students that went to holiday parties = (3/5) * 95
                                                                             = 57
So 57 students out of the 65 students in Grade 6 went for holiday parties. This way it is also possible to find the number of students that did not go for the holiday party. Subtracting 57 from the total of 65 students gives 8 and this is the number of students that did not go for the holiday party.
