Answer:
Domain {1,5,10,20}
Ranger {4,20,40,80}
Step-by-step explanation:
$1=4 quarters
$5=20 quarters
$10=40 quarters
$20=80 quarters
Domain {1,5,10,20}
Ranger {4,20,40,80}
Multiply denominator (in this case do 6x10)
Multiply the numerator (in this case do 1x1)
So the answer is 1/60
I'm guessing D, but no so sure.
You have not provided the options, therefore, I cannot give an exact answer. However, I can help you with the procedures.
We are given that the ratio between the width and the length of the flag is 10 to 19.
This means that:

Therefore, to get the correct choice, all you have to do is divide the width by the length, if the result is 10/19, then the dimensions given are correct.
Examples:For length = 190 and width = 100,
width / length = 100 / 190 = 10 / 19 .........> correct choice
For length = 1.9 and width = 1,
width / length = 1 / 1.9 = 10 / 19 .......> correct choice
Hope this helps :)
To find the surface area of a cylinder, use the formula SA = 2(pi)(radius^2) + 2(pi)(radius)(height).
So now, plug in what you know.
SA = 2(3.14)(5^2) + 2(3.14)(5)(9)
SA = (6.28)(25) + (6.28)(45)
SA = 157 + 282.6
SA = 439.6 square cm
439.6 square cm is your surface area
