1985year ->275cell phones->100%
1994year -> x cell phones ->100%+360%
40% • (1994-1985)= 40% • 9= 360%
275 cell phone 100%
X cell phones. 100+360%=460%
x=275•460%/100%
x=12420/100
x=1265
99% sure this is a correct answer
x=275 • 460%/100%
x=12,420/100
x=1265
1994-1985= 9 yrs • 40%= 360%
Answer: 
Step-by-step explanation:
a^2 +b^2 = c^2
4^2 = 16
6^2 = 36
16+36=52
c^2=52
c=
∠2 =∠1 which is 180° -65° =115<span>°
So </span>∠2=115<span>° </span>
Slope can be calculated using the formula: m= 
y1/x1 represents the first number in the bracket
y2/x2 represents the second number in the bracket
Calculation
m = 
m = 
m= 6/-12
m= -0.5 or -1/2
Therefore, the answer is B.
Answer:
