Answer:
- The area of a 17 in traditional TV is approximately 138.7 in².
- The area of a 17 in LCD TV is approximately 123.3 in²
- The 17 in LCD TV's screen is bigger
Explanation:
<u>1. What is the area of a 17in traditional tv screen? </u>
a) Measure of the diagonal = 17 in
b) The diagonal is the hypotenuse of a triangle.
c) Call x and y the length and the width of the screen. Then, by Pythagora's theorem:
d) Since the ratio of the length to the width of the screen is 4:3
e) Solve the system of equations:
- x = 10.2 × 4 / 3 = 13.6 in
f) Area = x × y = 10.2 in × 13.6 in = 138.72 in²
The area of a 17 inch traditional TV is approximately 138.7 in²
<u>2. What is the area of a 17in LCD TV whose screen is in 16:9 format? </u>
Solve the system of equations:
- x = 8.33 × 16 / 9 = 14.8 in
Area = x × y = 14.8 in × 8.33 in = 123.28 in²
The area of a 17 inch LCD TV is approximately 123.3 in²
<u>3. Which screen is bigger?</u>
The screen of the 17 in traditional TV is bigger, because its area (approximately 138.7 in²) is greater than the area of the LCD TV (approximatle 123.3 in²).
Answer: Choice B) Angle L = Angle O
---------------------------------------------------
---------------------------------------------------
If we know that Angle L is congruent to Angle O, then we can use the AAS (angle angle side) congruence property. We have one pair of angles marked by the square marker (angle J and angle M). So they are congruent angles. We have a pair of congruent sides JK = MN = 3. So we're just missing a pair of angles.
Note: The answer is NOT angle K = angle N because this would mean ASA would be used instead of AAS. The order of the letters is important as it establishes how the sides and angles relate. With ASA, the side is between the angles. With AAS, the side is not between the angles.
Answer:
Yes, it is a function
Step-by-step explanation:
It passes the vertical line test, therefore it is a function.
Answer:
1st choice: (3)(5)+(1/3)(5)+(3)(1/4)+(1/3)(1/4)
Step-by-step explanation:
This would be the next step because of distribution
