Answer:6.28
Step-by-step explanation:
C=pi*diameter
C=3.14*2
C=6.28
Let x be the total of students in their Junior Year.
So, 84% of x =378
84% = 0.84
0.84x=378 (divided by 0.84)
x= 450 students.
The ones that chose not to take spanish will be:
450-378=72
72 students chose not to take spanish in their junior year.
Answer:
f(x)= 3, g(x)=8
Step-by-step explanation:
if you plug 3 into the equation 2x-3, you have 6-3, which is 3.
If you plug 3 into the equation 3x-1, you have 9-1, which is 8
Answer:
509.35 feet
Step-by-step explanation:
16°23' means 16 degrees and 23 minutes. A minute is 1/60 of a degree.
16°23' = 16 + (23/60) = 16.383°
Similarly:
49°29' = 49 + (29/60) = 49.483°
When the boat is first noticed:
tan(16.383°) = 200 / a
a = 200 / tan(16.383°)
a = 680.27
When the boat stops:
tan(49.483°) = 200 / b
b = 200 / tan(49.483°)
b = 170.92
So the difference is:
a − b = 680.27 − 170.92 = 509.35
The boat traveled 509.35 feet from the time it was first noticed to the time it stopped.
