Answer:
He is watching TV for 2 hours and 40 minutes.
Step-by-step explanation:
We are given that the episodes of a TV program are each 40 minutes long. Phill watches four episodes together.
As it is stated that the length of each episode of a TV program is 40 minutes, so the length of four episodes is given by;
1 episode = 40 minutes
4 episodes = 4 
40
= 160 minutes
So, the length of four episodes together is 160 minutes.
Now, we have to convert the time in hours and minutes;
As we know that 1 hour = 60 minutes
160 minutes = 120 minutes + 40 minutes
= 2 hours + 40 minutes
Hence, the length of four episodes together is 2 hours and 40 minutes.
Answer:
i) 21 and ii) 6
Step-by-step explanation:
i) If X=4 and Y=6, then:
3X+9, replacing X
3(4) + 9
12 + 9
21
ii) 4X-Y
4(3) - 6
12 - 6
6
The distance from the base of the tree to the tallest would be 14.21 cm
<h3>We have the following data points in this question</h3>
X1 = 8 feet
y1 = 16 feet
x2 = 11 feet
y2 = 9 feet
To proceed with the solution we have to
We have to solve for the shorter tree
<em>= </em>9² + 11²
= √81 +121
= 14.21
<h3>For the taller tree we would have</h3>
√8² + 16²
= √64 +256
= 17.89

Answer:
1.90909 (Rounded to fifth decimal place)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Radius r = 15
Circumference = 2πr = 30π cm
Circumference of cone = arc length of sector
= 30π × 216°/360°
= 18π cm
Radius of base of cone = 18π/(2π) = 9 cm
Slant height of cone = radius of circle = 15 cm
Height of cone = √(15² - 9²) = 12 cm
