Jean is making bar graph for a presentation .She is planning for the length and width of the bars to have a ratio of 3:2, so that they satisfy this equation
2/=w
If one bar is 7 centimeters wide, what should be its length?
(21 cm)
14 cm
10 1/2 cm
4 2/3 cm
21
I need the answer. ANYONE HELP ME AND THE Q ASKER! PLZ!
Thats right
THANX
Is it right tho?
To solve this problem, we can set up a proportion using the given ratio and the width of the bar:
Length / Width = 3 / 2
Since the width is given as 7 centimeters, we can substitute this value into the equation:
Length / 7 = 3 / 2
Now we can cross-multiply to solve for the length:
Length * 2 = 7 * 3
Length * 2 = 21
Dividing both sides of the equation by 2, we can find the value of Length:
Length = 21 / 2
Length = 10 1/2 cm
Therefore, the length of the bar should be 10 1/2 cm.
