Answer:
1/2.
Step-by-step explanation:
10m = 5n
m = 5n/10
m = n/2
m/n = n/2 * 1/n
m/n = 1/2.
First you have to do

.
Since the car is moving at a constant rate, the answer would be
8h.
Answer:
The answer is below
Step-by-step explanation:
Let us assume the rate of printing in machine A is x per hour and the rate for machine B is y. Given that machine B prints at half the rate of machine A, therefore:
y = (1/2)x (1)
Also, both machine produces 200 newspaper printouts, and both operate at different times for a total of 4 hours. Therefore:
200/x + 200/y = 4 (2)
Put y = (1/2)x in equation:

Put x = 150 in equation y:
y=(1/2)150 = 75
Therefore the rate of machine A is 150 newspapers per hour while that of machine B is 75 newspapers per hour
I think the answer is 360
16pi
Step-by-step explanation:
pi x r² = ans ÷ 4 = Answer for area
Pi×8²=64pi ÷ 4 = 16pi
