Answer:
1800
Step-by-step explanation:
Since there is the tragon fly beat his wings 30 times a second ,there is 60 hundredths of a second in a second multiply 30 x 60 and you should get 1800.
- mulitiply 0x0 = 0
2. mulitiply 6x0=0
3. multiply 3x0=0
4. mulitiply 6x3 = 18
5. have 1800
or you can just multiply 6x3 = 18 and add the two zeros
Answer:
219m
Step-by-step explanation:
Since the man observes the car with angle 15 before observing in 33 degrees.
For the first observation
The angle observation gives an angle if 33 degrees with the horizontal.
It gives a triangle which I'll attach to the que,
from the first triangle
Tan 33 = 100/y
Y= 100/ tan 33
Y = 153.99m.
This is the distance from the building to the distance where it was secondly observed( 33).
To find x
tan 15 = 100/(153.99+x)
153.99 + x = 100/ tan 15
153.99 + x = 373.21
The distance between the two observed angles
X= 219m.

Answer:
60 miles per hour
Step-by-step explanation:
Speed in miles per hour is found by dividing miles by hours:
(120 mi)/(2 h) = (120/2) mi/h = 60 mi/h
