The aspect ratio of a TV screen is the ratio of the horizontal length to the vertical height. If the TV has a diagonal of 100 cm and the aspect ratio is 4:3, then find the horizontal length and the vertical height of the TV screen.
Answers
Answer:
The horizontal length is 80 cm, and the vertical height is 60 cm.
Step-by-step explanation:
The aspect ratio is the ratio of the horizontal length to the vertical height.
We have a rectangle with sides 4 and 3. We can find the length of the diagonal.
We can use the Pythagorean theorem to find the length of the diagonal.
a^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = c^2
c^2 = 25
c = 5
The diagonal is 5 in the ratio.
The ratio of the horizontal length to the vertical height to the diagonal is
4:3:5
We multiply all the numbers in the ratio by the same unknown, x.
A ratio of 4:3:5 is the same as a ratio of 4x:3x:5x.
We are told that the diagonal is 100 cm, so we have
4x : 3x : 100,
but we already had a ratio of
4x : 3x : 5x, so
5x = 100, and we can find x.
5x = 100
Divide both sides by 5.
x = 20
Since x = 20, then the horizontal length 4x = 4(20) = 80,
and the vertical height 3x = 3(20) = 60
Answer: The horizontal length is 80 cm, and the vertical height is 60 cm.
Answer:
horizontal length=80, vertical length=60
Step-by-step explanation:
a^2 + b^2 = c^2
the tv is a 3:4:5 right triangle
the ratio is then changed from
3:4:5
to
60:80:100
because 100/5 = 20
so you multiply the original ratio by 20
(because the length of 100 that we are given is the hypotenuse of the triangle(diagonal of the tv))
Therefore,
the horizontal length is 80
the vertical lengt is 60

Answers
I'm assuming you mean that <C=68 degrees.
Now we know that the interior angle of a triangle adds up to 180 degrees.
We just need to subtract the 2 already known angles from it.
180 degrees-56 degrees-68 degrees=180 degrees-124 degrees=56 degrees.
Done!
<B=56 degrees.

Answers
Answer:
-10d-4
Step-by-step explanation:
Well, you're in luck because I LOVE distributive property!!!
-4(2d+3) Multiply -4 by 2d to get -8d, and multiply -4 by 3 for -12, so the result would be -8d-12!
Then, 2(-d+4) and therefore 2 times -d (you can just say -1d) to get -2d and 2*4 would be 8 to make -2d+8!
Now you combine them: -8d-12+-2d+8
Combine like terms!
-10d-4 would be your answer.

Mr. Lyle made a round trip between two cities that were 450 kilometers apart. On the return trip, he increased his average of rate travel by 5 km/h and made the trip in one hour less. Find his rate for each direction.
Answers
Answer:
45 km/h
50 km/h
Step-by-step explanation:
Distance traveled in one way = 450 km
Let x = Velocity when he was going to his destination in km/h
He traveled 5 km/h faster when he returned so his velocity was [tex]x+5[/tex]
It took him 1 hour less when he returned so
[tex]\dfrac{450}{x}-\dfrac{450}{x+5}=1\\\Rightarrow x^2+5x-2250=0\\\Rightarrow x=\frac{-5\pm \sqrt{5^2-4\times 1\times \left(-2250\right)}}{2\times 1}\\\Rightarrow x=45,-50[/tex]
So, velocity while going to his destination is 45 km/h
While returning his velocity was 45+5 = 50 km/h.
