Given:
t A = 2.4 h
t B = 4 h
v A = 22 + v B
Solution:
Distance A and distance B is the same, distance could be defined using formula d = v × t
d A = d B
(v A × t A) = (v B × t B)
plug in the numbers
v A × 2.4 = v B × 4
(22 + vB) × 2.4 = 4 vB
remove the parenthesis using distributive property
(22 × 2.4) + (2.4 × vB) = 4vB
52.8 + 2.4vB = 4vB
add like terms
52.8 = 4vB - 2.4vB
52.8 = 1.6vB
52.8/1.6 = vB
vB = 33
the speed of car B is 33 mph
vA = 22 + vB
vA = 22 + 33
vA = 55
the speed of car A is 55 mph
Answer:
20
Step-by-step explanation:
I'm not sure at all I'm sorry
You multiply 6.5 *4 =26 then you multiply 26 *6= 156 so that's $156.00.
Answer:

Step-by-step explanation:
If the system contains
atoms, we can arrange
quanta of energy in
ways.

In this case,
.
Therefore,

which means that we can arrange 1 quanta of energy in 2 ways.

In this case,
.
Therefore,

which means that we can arrange 10 quanta of energy in 184 756 ways.

In this case,
.
Therefore, we obtain that the number of ways is

31.51
r=−5
d=19
h<53
