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.
4. 5/6x3/5=15/30=1/2, 4/8 simplified would be 1/2 so they're the same. 6. 4/9x7/8= 28/72=7/18, 8/18x21/24= 1/6x7/3=7/18 so they're the same. :) I hope this helps
Answer:
thank you that felt good and can you give me brain please and thank you!!!!!!!!!
Step-by-step explanation:
The equation given in the question is definitely solvable for finding the value of the unknown variable "x". There is only one unknown variable and one equation.The equation given in the question is
10/8 = (x - 10)/10
(10 * 10)/8 = (x - 10)
100 = 8(x - 10)
100 = 8x - 80
Reversing the two sides, we can write the equation as
8x = 100 + 80
8x = 180
x = 180/8
= 22.5
So the value of the unknown variable comes out to be equal to 22.5. I hope the procedure is clear enough for you to understand.
