G) 49, H) 60 2/3
If the second one is wrong, u didn't say what to solve it as.
Answer:
Step-by-step explanation:
A circle is divided into 8 equal parts means : 360°/8 = 45°
the total angle measure of 4 parts is :
45°×4=180°
142.35 miles. Just multiply 189.80 by 3/4 (or .75).
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).
Total amount of money is 33000
There are two recipients of the money, and one is getting 1000 more than the other
Let H = Hannah
Let T = Taylor
T + H = 33000
Since Taylor is getting 1000 more than Hannah, T = H + 1000
So, H + (H + 1000) = 33000
2H + 1000 = 33000
2H = 32000
H = 16000
<u>Hannah gets 16000</u>
<u>Taylor gets 16000 + 1000 = 17000</u>
