Answer:
A) Length = 110.4 mm and width = 62.1 mm
B) A = 6855.84 mm² 
C) length = 114.7 mm
width = 55.8 mm
Area = 6400.26 mm²
D) Screen with aspect ratio of 16:9 is bigger
Step-by-step explanation:
A) We are told that the aspect ratio of the phone screen = 16:9. This means that the ratio of the length to the width of the screen is 16:9.
To find the side length, we will say that;
length = 16x 
width = 9x
Thus, since the edges are perpendicular, then we can use pythagoras theorem since we know that the diagonal is 127 mm
Thus;
(16x)² + (9x²)] = 127²
256x² + 81x² = 16129
337x² = 16129
x² = 16129/337
x = √(16129/337)
x = 6.9
Thus;
length = 16x = 16 × 6.9 = 110.4 mm
width = 9x = 9 × 6.9 = 62.1 mm
Length = 110.4 mm and width = 62.1 mm
B) area of screen is;
A = length × width
A = 110.4 × 62.1
A = 6855.84 mm²
C) We are told that the aspect ratio is now 18.5:9.
Thus;
length = 18.5x 
width = 9x
Thus;
(18.5x)² + (9x²)] = 127²
342.25x² + 81x² = 16129
423.25x² = 16129
x² = 16129/423.25
x = √(16129/423.25)
x = 6.2
length = 18.5x = 18.5 × 6.2 = 114.7 mm
width = 9x = 9 × 6.2 = 55.8 mm
Area = 114.7 × 55.8 = 6400.26 mm²
D) Screen with aspect ratio of 16:9 is bigger
 
        
             
        
        
        
Time is your independent variable, and snowfall is your dependent variable. 
Slope can be found by calculating ∆y/∆x:

Snowfall will accumulate 0.02 m every hour.

Answer:
a. k = n - 1     b. 15    c. 112
Step-by-step explanation:
I can answer a. b. and c. for you!
For a. let's say that the variable k means keys. And n means bits.
Since Millie can collect one less keys than there are bits, the equation is....
*See top*
For b. if Antonio  has a 16-bit system, by looking at our equation we know that k = n - 1.
So, if n = 16, k = 15
For c. if each byte equals 8 bits, and there are 14 bytes, then the amount of bits would be 8 x 14.
8 x 14 = 112
