Question

Your friend is looking at laptops for college, and is comparing the different

screen sizes. Use the diagram and formula below to find the height of the
laptop screen. Round your answer to the tenths place.

Answer 1

D. H=7.0
Exp:
Use the equation and rewrite to find what h equals, h= sq.rt.(d^2-w^2)
When the numbers are plugged in and you solve for H, h=7

Answer 2

Answer : The height of the laptop screen is, 7.0 in

Step-by-step explanation :

As we are given that the expression as:

`d=√(w^2+h^2)`

Given:

w = 11.3 in

d = 13.3 in

Now put all the given values in the above expression, we get:

`d=√(w^2+h^2)`

`13.3=√((11.3)^2+h^2)`

Squaring both side, we get:

`(13.3)^2=(11.3)^2+h^2`

`(13.3)^2=(11.3)^2+h^2`

`176.89=127.69+h^2`

`h^2=176.89-127.69`

`h^2=49.2`

`h=√(49.2)`

`h=7.0in`

Therefore, the height of the laptop screen is, 7.0 in
