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
1 true and false question = 1 / 2 chances
2 multiple choice question = 2/8
1/2 + 2/8 =
4/8 + 2/8 = 6/8.
6/8 = 3/4
you have a 75% chance of getting all 3 answers correct and getting a 100% on the quiz
hope this helps :D
Answer:
CE = 16
Step-by-step explanation:
<u>From my understanding, the length of cord AB is given. According to the question in the picture attached, you need to find CE.</u>
<em>Triangle ABD and triangle ACE are similar.</em>
<em>Therefore, AB/AC = BD/CE</em>
<em>AB = 6, AC = 8, BD = 12, CE = ?</em>
<em>6/8 = 12/CE</em>
<em>CE = 12x8/6</em>
CE = 16
Therefore, CE is equal to 16.
