The diagonal of the tv screen is given by:
d = root ((w) ^ 2 + (h) ^ 2)
Where,
w: width
h: height
In addition we have the following relationship:
h / w = 8/15
Thus,
For the width:
d = root ((w) ^ 2 + ((8/15) w) ^ 2)
For the high:
d = root (((15/8) h) ^ 2 + (h) ^ 2)
Answer:
The expressions for the width and height of a wide-screen tv in terms of the length of its diagonal are:
d = root ((w) ^ 2 + ((8/15) w) ^ 2)
d = root (((15/8) h) ^ 2 + (h) ^ 2)
-z = 80
You cannot submit an equation with a negative letter ( -z ) so we have to cancel the negative.
To cancel negatives in the equation, we multiply both sides by -1.
-z * -1 = 80 * -1
z = -80
Answer: z = -80
51 + 3x+5 = 107
Simplify the left side:
3x + 56 = 107
Subtract 56 from both sides:
3x = 51
Divide both sides by 3:
x = 51 / 3
x = 17
Angle F and the outside angle of 107, need to equal 180 degrees.
F - 180 - 107 = 73 degrees.
Well, you get the volume by multiplying the height, the width, and the length. So just work on it backwards.
2,830.5 divided by (9 times 18.5).
9 times 18.5 is 166.5. So that leaves us with 2,830.5 divided by 166.5, which is 17.
So, the answer is 17.
