Answer:
-2
Step-by-step explanation:
-9=4n-1
4n=-9+1
4n=-8
n=-8/4
n=-2
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:
An impossible one...
Step-by-step explanation:
The 3 interior angles of a triangle must add up to 180°
therefore no triangle can be 25,15,20 since that would add up to 60°
rounding 2.289 to the nearest ten gives you 0. its that simple ;)
AC is the hypotenuse of triangle ABC.
Because the length is 6√2 and angle A is 45 degrees, we know the length of both sides is 6.
This means AB is 6, which it the hypotenuse of triangle BCD.
Using cos(angle) = adjacent leg / hypotenuse we can find x:
cos(60) = X / 6
x = 6 * cos(60)
x = 3
