4%
To find the percentage, first find the area of both circles. The area formula is
. After finding the area of the center of the target (19.625) and the area of the large target (490.625), set up a percent proportion to determine the percentage that the center takes up:
Cross multiplying and dividing by 490.625 will give a total of 4%.

Answer:
Answer is 6.5 dollars.
Step-by-step explanation:
Cost of movie tickets and snacks in total = 43.50
Cost of tickets = $24
Cost of Snacks = 43.50-24 =19.5$
number of snacks = 3
Cost of one snack = 19.5 ÷ 3 = 6.5$
Answer:
In fact, the AB could be calculated in a quickest way, using Pythagorean theorem. In here, we try to use the property of trigonometry to work out AB.
Before applying trigonometry, in this right triangle we can calculate the remaining angle C:
C = 180 - 90 - A = 180 - 90 - 53.13 = 36.87 deg
We can use cosine formula, but here we use the sine formula for the sake of convenience. We have:
sine(angle measure) = ratio of opposite side over hypotenuse
In detail, sineC = AB/BC
Then, we have: AB = BC x sineC = 15 x sin(36.87 deg) = 9.000002 = ~9 ft
Hope this helps!
