Answer:
41 cars and 86 trucks
Step-by-step explanation:
C+T=127
2C+4=T
C+(2C+4)=127
3C+4=127
3C=123
C=41When C=41,
41+T=127
T=127-41
T=86
kyle is 18 and megan is 9, because 9 + 18 = 27 and 27 / 3 = 9. hope this helps :)
Answer: 352/105
Step-by-step explanation:
Diameter of the circular disk is
(2−x2)−x2
so that the radius of the disk is the diameter divide by 2
(2−x2−x2)/2.
Integrating V at 1 and -1, we get
V =Z 1−1A dx =Z 1−1π(1 − x2)2
dx = π(x −2/3x3 +1/5x5)1−1
=16/15π
= 352/105
The answer is really easy you can go through anything
Answer:
1.) 15.24 J
2.) 7.62 W
Step-by-step explanation:
Given that You do a pull-up, lifting yourself by 0.5 in 2 seconds. If your weight is 600 N,
Convert inches into metres
1 inches = 0.0254 metres
Work done = Force × distance
Work done = 600 × 0.0254
Work done = 15.24 J
Power is the rate at which work is done.
That is,
P = WD / time
Power = 15.24 / 2
Power = 7.62 W
Therefore, 15.24 Joule of work done must be done and 7.62 watt of power output must be required to lift the yourself.
