Forty thousands place or the place value: Ten thousands place
Answer:
the domain would be everything but -5 and 5. so all real numbers except for 5 and -5
It would have to be 5 60/100
(5 wholes and sixty out of a hundred)
Plane's air speed is 437.5 mph
Wind velocity is 87.5 mph
An actual question hasn't been asked, but an educated guess would be to determine the plane's airspeed or the wind velocity. So I'll calculate those values for you.
When traveling with the wind, the combined speed is 2100/4 = 525 mph.
When traveling against the wind, the combined speed is 2100/6 = 350 mph.
So we can create 2 equations with 2 unknowns. They are:
a - b = 350
a + b = 525
Let's add the two equations together.
a - b = 350
a + b = 525
2a = 875
a = 437.5
So the plane's speed in still air is 437.5 mph.
Let's calculate the wind velocity.
a + b = 525
437.5 + b = 525
b = 87.5
And the wind velocity is 87.5 mph
Answer:
minutes
Step-by-step explanation:
We have been given that the average wait time at a hospital increased by 70%.
Initially average wait time was <em>m </em>minutes. But later it increased by 70%.
Let there are <em>n </em>number of patients and it takes <em>t </em> minutes to examine each patient.
So the initial average waiting time is:
minutes
After the outbreak the waiting time increased by 70%. So the new waiting time should be the sum of initial waiting time and additional waiting time that is:
New waiting time = 70% +
