Answer:
the difference is 143
explanation
How to Find the Difference between Two Numbers. To find the difference between two numbers, subtract the number with the smallest value from the number with the largest value. The product of this sum is the difference between the two numbers. Therefore the difference between 45 and 100 is 55.
so 120-(-23) is 141
Answer:
huh?
Step-by-step explanation:
Answer:
x = 20
p =54
y= 54
Step-by-step explanation:
2x-4 = 96-3x
5x = 100
x = 20
2x-4 = 40-4 = 36
(180 - (36 x 2))/2
(180-72)/2
108/2
p = y =54
The question here is how long does it take for a falling
person to reach the 90% of this terminal velocity. The computation is:
The terminal velocity vt fulfills v'=0. Therefore vt=g/c,
and so c=g/vt = 10/(100*1000/3600) = 36,000/100,000... /s. Incorporating the
differential equation shows that the time needed to reach velocity v is
t= ln [g / (g-c*v)] / c.
With v=.9 vt =.9 g/c,
t = ln [10] /c = 6.4 sec.
The mass of the first shipment at time t is

The mass of the second shipment at time t is

At time t, the ratio of m₁ to m₂ is

Therefore as a percentage,

Answer: B. 81.2%
