Answer:
17.83
Step-by-step explanation:
d = r*t
d = 41 miles
t = 2.3 hours
r = ??
d = rt Substitute
41 = r * 2.3 Divide by 2.3
41 / 2.3 = r Switch sides
r = 41/2.3
r = 17.83 mph Answer
The volume of the original prism is given by:
V1 = (10) * (2) * (h)
rewriting:
V1 = 20h
Where,
h: height
The volume of the second prism is given by:
V2 = (5) * (w) * (h)
We know that the height is the same.
As the volume is the same then:
(5) * (w) * (h) = 20h
Clearing w we have:
w = (20/5) = 4 cm
Answer:
The width, in centimeters, of the new prism is:
w = 4cm
multiply 40 by 30% to find the discount then subtract
40 * 0.30 = 12
40-12 = 28
they would cost $28
Step-by-step explanation:
It is given that,
Initial speed of the car, u = 40 m/s
Final speed of the car, v = 25 m/s
Time taken, t = 3.5 s
(a) We need to find the magnitude and direction of the car’s acceleration as it slows down. It can be calculated using formula as :
The acceleration is in the opposite direction of motion i.e. west.
(b) Let s is the distance the car travel in the 3.5-s time period. It can be calculated using the third equation of motion as


s = 113.9 meters
Hence, this is the required solution.
