Answer:
79 minutes
Step-by-step explanation:
A plane is travelling at 180 meters per seconds
Convert to km/hr
180× 18/5
= 648 km/hr
Since 648 km equals 1 hour then the number of minutes required for the plane to travel 800 km is
= 1/648 × 800
= 1 hour 19 minutes
Conver the time to full minutes
60 minutes = 1 hour
= 60+19
= 79 minutes
Hence the minutes required for the plane to travel 800km is 79 minutes
Answer:
8
Step-by-step explanation:
Answer: C.5
Rearranging the given data into ascending order, we get
3,3,4,4,5,6,7,
Total number of observations =7 which is odd
Hence, the 4
th
term is the median.
∴ Median =4
Hence, option (C) is the correct answer.
Answer:
(a) y = 25°
(b) x = 90°
(c) z = 25°
Step by step explanation:
<u>Part A</u>
z + 90° + 65° = 180°
z = 180° - 65° - 90°
z = 25°
<u>Part B</u>
x + 90° = 180°
x = 90°
<u>Part C</u>
x + 65° + y = 180°
90° + 65° + y = 180°
y = 25°

:</h3>
A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.
