Set up a proportion.
Let x = the number of students in 29970 who speak 3 or more languages.
285/19 = 29970/x Cross multiply
285 x = 19 * 29970
285x = 569430
x = 569430/285
x = 5415 students speak 3 languages.
Answer:
Y=⅘X+2. the picture not clear so i hesitate
Answer:
the common difference of the sequence is 
Step-by-step explanation:
A sequence of numbers is said to be in arithmetic progression of each term of the sequence has same common difference.
Now, here first term a1 = 1/4
Second term a2 = 5/16
Third term a3 = 3/8
Now, Common difference (d) = a2 - a1 = a3 - a2
Now, a2 - a1 = 
Now, a3 - a2 = 
Hence, the common difference of the sequence is 
Answer:
sin(a)=20/29
cos(a)=21/29
