Since the symbol tells us the angle is 90 degrees we know the 4x and 5x add up to make 90 degrees.
Lets use this to make and form an equation
5x + 4x = 90
9x =90 (collect the x values)
x = 10 (divide both sides 9 to find what x is)
X is the center of the circle
Answer:
2 minutes
Step-by-step explanation:
The front of the train enters the tunnel and travels 1 km before the rear of the train enters the tunnel. Thus, the total distance traveled by the front of the train is 2 km, and this is covered in a certain number of hours:
Since distance = rate times time, time = distance / rate. In this particular case we have:
2 km
time = distance / rate = ------------------- = (1/30) hr
60 km/hr
(1/30) hr converts to 2 minutes, since 1 hr = 60 minutes
Answer:
15u³
Step-by-step explanation:
To find volume ↓
Volume
= length × width × height
= 2u × 2½u × 3u
= 15u³
