Step-by-step explanation:
Answer:
9x + 5y
Step-by-step explanation:
Find the missing angles using either the triangle sum theorem (a2+b2=c2) or inverse trigonometric ratios
Answer:
x + y + z = 272 - - - - - - (1)
x = 3y - - - - - - - - - - - - - (2)
z = 32 + y - - - - - - - - - - (3)
Step-by-step explanation:
Let :
Number of pop songs = x
Number of rock songs = y
Number of hophops = z
Sum of the three types of songs = 272
x + y + z = 272 - - - - - - (1)
Pop is 3 times Rock :
x = 3y - - - - - - - - - - - - - (2)
Hiphop is 31 more than rock
z = 32 + y - - - - - - - - - - (3)
Answer:
R = 3.6
A = 2
Step-by-step explanation:
R is inversely proportional to A
....which means that....
; R = k/A.....(where k is a constant that does not change)....
;If R = 12 and A = 1.5....then k = 18..
obtain k,by substituting the values into the equation...k = RA
a) If A = 5....then R = 18/5....
; Ans..., R = 3.6
b) If R = 9....then A = 18/9
;Ans..., A = 2
