Answer:
900
Step-by-step explanation:
The ratio of the number of people who own a smartphone to the number of people who a flip phone is 5:3.
Let the number of people who own a flip phone=x
If 600 more people own a smartphone than a flip phone, then the number of people who own a smartphone=x+600
To find x, we express the ratio and population as an equality.
5:3=x+600:x
Expressing the ratios as fractions would give:
Next, we cross multiply
5x=3(x+600)
Open the brackets by expansion.
5x=3x+(3 X 600)
5x=3x+1800
Subtract 3x from both sides.
5x-3x=3x-3x+1800
2x=1800
Divide both sides by 2
x=900.
Since x=900, the number of people who own a flip phone is 900.

Step-by-step explanation:
Given the surdic equation as shown
To find the quotient, we will rationalize by multipying both numerator and denominator of the function by the conjugate of the denominator.
Given the denominator , its conjugate will be
Multiplying through by , we have;
The final expression gives the requires answer
There are several ways you can answer this. The law of cosines may be helpful. It tells you
... c² = a² + b² - 2ab·cos(C)
or
... cos(C) = (a² + b² - c²)/(2ab)
If this value is negative, then angle C is obtuse. Since 2ab is always positive, it amounts to finding the sign of
... a² + b² - c²
Of course, for repetitive calculations, a spreasheet or other machine evaluator is helpful.
The results shown in the figure indicate that side lengths {5, 7, 8} result in an acute triangle.
