Answer:
A
Step-by-step explanation:
While fractions are more exact, it will always depend on the scenario. You aren't going to give the amount of money something is as a fraction, that will always be a decimal. However, in most math circumstances, fractions can get more straight to the point since there is no such thing as a truly repeating fraction.
The first thing we must do is find the percentage that has traveled outside of the United States.
For this, we make the following rule of three:
30 ---------> 100%
9 -----------> x
We clear the value of x:
x = (9/30) * (100)
x = 30%
Then, for 120 sixth graders in the school we have:
(0.30) * (120) = 36
Answer:
36 students have traveled outside of the united states
Answer:
3x+5y=4
Step-by-step explanation:
y=-3x/5 + 4
move the 5 to the other side so:
5y=-3x+4
then move -3x to the other side so:
5y+3x=4
and that is yr answer
Answer:
The number of students who collected exactly 9 bottles.
Step-by-step explanation:
The given histogram shows the number of students who participated in the recyling drive & their old bottle waste collection.
We can find out the total number of students who participated just by looking at the histogram (students = 10), the number of students who colected bottles below 7 or 3 bottles etc.
But since the number of bottles is given in the form of grouped data, one cannot infer the exact number of bottles collected by students.
Hence, out of the given statements, 'The number of students who collected exactly 9 bottles' is the incorrect one.
No, a triangle can't be made with sides of those lengths.
-- The 10 and the 20 must be hooked together somewhere on the triangle.
One end of the 10 is connected to one end of the 20.
-- Now imagine the distance between the OTHER ends of those sides.
If the 10 and the 20 are folded together so that they both go in the same
direction and there's no angle between them, the closest their OTHER ends
can be is 10 units apart.
-- So if you want to stick a 3rd side between them and make a triangle,
the 3rd side has to be AT LEAST 10 units long. If it's any shorter than
10 units, it can't reach the open ends of the 10 and the 20.
-- Seven is less than 10.
So it can't reach the open ends of both the 10 and the 20 at the same time.
