Original Ratio of 1 in = 7 ft so 3 in = 21 ft
Now, New ratio 1 in = x ft so 3 in = 27ft
1/x = 3/27
cross multiply a/b = c/d ad = bc
1/x = 3/27
3x = 27
x = 9
1 in represents 9 ft
Answer:
edge 2020
Step-by-step explanation:
The data appears slightly skewed, so the median is probably the most appropriate measure.
My friend has a good chance of making between $16,000 and $23,000 because that is the range for the middle 50% of employees.
Answer:
The value of y is -5
Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
If x and y satisfy both equations, then (x,y) is the solution of the system of equations
Using a graphing tool
Remember that
The solution of the systems of equations is the intersection point both graphs
The intersection point is (2,-5)
therefore
The solution of the system of equations is the point (2,-5)
The value of y is -5
Answer:
A.) The temperature fell in the last minute, but less than it fell in the minute before.
Step-by-step explanation:
Given that for three minutes the temperature of a feverish person has had negative first derivative and positive second derivative.
i.e. it temperature is represented by T, temperature is variable with
first derivative T' <0 and second derivative T">0
i.e. rate of change of temperature is negative or temperature is falling down in 3 minutes.
But the rate of rate of change of temperature was positive i.e. the rate of change of temperature is increasing as time increases.
So correct option would be option A
A.) The temperature fell in the last minute, but less than it fell in the minute before.
