If varies directly as , then there is some constant for which
Similarly, there is some constant such that
Given that when , we have
Now when , we get
Fraction: 17/20
Divide by 4 to get 17/20
(68/4)/(80/20)
Percent: 85%
Using 17/20 -Multiply each side by 5 to get ____/100
17*5/20*5 = 85/100 or 85%
Decimal: 0.85
Using 85/100, divide it out to get 0.85.
First, 5 students and 2 teachers is 7 different people. That means there are 7! Ways they can stand in a line. (7! Means 7x6x5x4x3x2x1)
That is 5040 ways.
Having the teachers on either side with the five students in the middle splits the question. There are 2 ways the teachers could stand (TA on left, TB on right or vice versa). There are 5! Ways to arrange the students in the middle. That is, 120. So combined, there are 2x120 ways to have them lined up with the teachers on either side. 240 ways.
Out of the 5040 ways for all of them to line up, one teacher will be in the middle 3 spaces 3/7 of the time. The second teacher will be on one of the remaining 2 central spaces 2/6 (1/3) of the time. 3/7x1/3 = 1/7. That means 1/7 or 14.29% of the time, the two teachers will occupy two of the three middle slots.
Answer:
42
Step-by-step explanation:
12+12+9+9=42
the smaller added 3 in. to the height so you add 3 in. to the width.
hope this helps :)
