Answer:
22 3/4 ft
Step-by-step explanation:
The diagram seems to show a 6 1/2 ft person casting a 9 ft shadow at the same time a flagpole is casting a 31 1/2 ft shadow. You want the height of the flagpole.
<h3>Proportion</h3>
Shadow lengths are presumed proportional to the height of the object making them. This means ...
h/(31 1/2) = (6 1/2)/9 . . . . . all lengths in feet
Multiplying by 31 1/2, we get ...
h = (31 1/2)(6 1/2)/9 = (819/4)/9 = 91/4
h = 22 3/4 . . . . ft
The flagpole is 22 3/4 feet tall.

Answer:
10y mm
Step-by-step explanation:
We would need to know the conversion of cm to mm.
We know
1 cm = 10 mm
If we are given a certain amount of centimeters (cm), to get the answer in millimeters (mm), we multiply that by 10. Example:
1 cm = 10 mm
4 cm would be 4 * 10 = 40 mm
23 cm would be 23 * 10 = 230 mm
Now, we are given "y" centimeters.
So, we multiply by "10" to get the answer in millimeters.
Hence,
y * 10 = 10y millimeters (mm)
The line is 10y mm
X = total amount of people
80% of x = 540
.8x = 540
x = 675
There were 675 people
