Answer:
There are 1200 vertical pixels.
Step-by-step explanation:
This is a ratio problem, which uses ratios to relate different items in the question. In a ratio problem, it's important to remember to
1) Write the items in the ratio as a fraction.
2) Make sure that you have the same items in the numerator and denominator.
→ Step 1:
The first step is to assign variables. Let x = vertical resolution of the 23" monitor.
Write the items in the ratio as a fraction.
[tex]\frac{horizontal}{vertical} = \frac{1680}{1050} = \frac{1920}{x}[/tex]
→ Step 2:
Solve the equation.
Cross multiply:
[tex]1680*x = 1920 * 1050[/tex]
[tex]1680x=2016000[/tex]
Isolate variable x:
[tex]x=\frac{2016000}{1680}[/tex]
[tex]x=1200[/tex]
