Semester 1:
let the number of students in the art class be 2a, and the number of the students in the gym class be 7a. (check: the ratio is 2a:7a = 2:7)
so the total number of students is 9a.
semester 2:
the 9a students are go to the art class and gym class at a a ratio of 5: 4,
so 5a students go to the art class, and 4a students go to the gym class.
<span>75 students are in art class in second semester means that 5a=75,
so a=75/5=15.
In the 1st semester the number of students was:
art class: 2a=2*15=30
gym class: 7a=7*15=105</span>
Option B: 4.0 cm is the value of w
Explanation:
It is given that 
, 
, 
and 
Using the law of sines, we have,
Substituting the values, we have,
Cross multiplying, we get,
Simplifying, we have,
Dividing both sides by 0.515, we have,
Thus, the value of w is 4.0 cm
Hence, Option B is the correct answer.
Answer:
False
Step-by-step explanation:
Since the b value (the value inside the parentheses) is less than 1, it represents exponential decay.
