There are 250 students in sixth grade
<em><u>Solution:</u></em>
Given that, All the students in the sixth grade either walk home or take the bus home after school
From given,
Number of students walk home = 170
Let "x" be the total number of students in school
32% of the students take the bus
Thus, 32 % of "x" takes bus
<em><u>To find: total number of students in school</u></em>
Total students = Number of students walk home + number of students takes bus

Thus there are 250 students in sixth grade
Answer:
Step-by-step explanation:
Even though you didn't provide options from which to choose, you don't need them to figure out the system. We need an equation that involves the NUMBER of people and then we need an equation that involves the MONEY earned. Two different things here.
As for the number of people, we know that the number of adult tickets + the number of children = 12 people, so
x + y = 12.
That's the first equation. Now for the money:
21.50x + 14.75y = 204.00
That's your system.
You want to cover 56 inches, 8*7=56. It will cost $70 to cover the book.
A = 30% of B = 0.3B
B = 90% of C = 0.9C
A = 0.3(0.9C) = 0.27C = 27% of C
The Law of Sines says



We don't have to worry about the obtuse supplement because a triangle can only have one obtuse angle, and that's B.

Answer: A=29.44°, C=34.96°
