The television set has a rectangular shape. The diagonal of this rectangle along with its width and length together form a right angular triangle.
This means that we can apply the Pythagorean theorem which states that:
(diagonal)^2 = (length)^2 + (width)^2
Let the width be w. We know that the length is 0.75 times the width, this means that: length = 0.75 w
Substitute in the above equation:
(20)^2 = (0.75w)^2 + (w)^2
400 = 0.5625 w^2 + w^2
400 = 1.5625 w^2
w^2 = 256
w = 16
This means that the width of the screen is 16 in.
Pr(1/2) for both I believe. If not right sorry.
Answer:
<h2>x = - 1/2</h2><h2 />
Step-by-step explanation:
-x + 9x = -4
8x = -4
x = -4/8
x = -1/2
Answer:
15
Step-by-step explanation:
but not for sure
Well if each dimension is made 6 times smaller and we have 3 dimensions. so we would have to divide each dimension by 6. if we divide each dimension by 6 then we divide by 6 to the third power or 6^3. which is 218 times smaller. so if it was a cube and its actual dimension was 6 x 6 x 6, the volume of this is 218. then each dimension is 6 times smaller. this means divide each by 6 and we get 1 x 1 x 1. the volumenof this is 1 cubic foot. so it would be 218 times smaller.
