Answer:
The length of the diagonal of the TV screen is 51.40.
Step-by-step explanation:
Given:
Aspect ration of Screen = 16:9
Also The Width (w) from exercise 4 is = 25.2
We need to find the length of the diagonal of the TV screen.
Solution first we will find the Length (l) of the TV screen
Now we know that;
Substituting the value of width 'w' we get;
Hence Length (l) =44.8
Now we know that;
Diagonal of TV screen is equal to Square root of sum of square of Length (l) and width (w).
framing in equation form we get;
Diagonal of TV screen = 
Hence The length of the diagonal of the TV screen is 51.40.
Answer:
19 m
Step-by-step explanation:
Perimeter = 2(length + width) ; P = 2(l+w) - - (1)
Area = Length * width ; A = l*w - - - (2)
76 = 2(l+w)
76/2 = l+w
l+w = 38
l = 38 - w
Put l = 38 - w in (1)
A = (38-w)*w
A = 38w - w²
At maximum point:
dA/dw = 0
dA/dw = 38 - 2w
38 - 2w = 0
38 = 2w
w = 38/2
w = 19
1,662,209 is the answer. You just have to add them all up
Alright, so if we wanted to take, for example, cell phone owners per 100 people and compare Germany to the USA, we can start by making up a number for Germany - 80 - and a number for the USA - 70. Next, the ratio of people using cell phones is 80/70=8/7 with the numerator being the people from Germany and the denominator being the number from the USA.
