It should be 13 as well
Because the arc length of CDE and ABCD are both 90 degrees. They share 20 degrees from arc CD and they already both have 70 degrees. So if the arc length is equal, the corresponding chords should be equal too.
Answer:
The 4 packages of 15 tops for $18 is a better deal
Step-by-step explanation:
We can see which set of tops have the lowest unit price.
4 packages of 15 tops for $18:
4*15=60
There is a total of 60 tops for $18, which means each top costs 18/60 dollars, or $0.30.
5 packages of 10 tops for $16
5*10=50
There is a total of 50 tops for $16, which means that each top costs 16/50 dollars, or $0.32.
0.32>0.3
The 4 packages of 15 tops for $18 is a better deal :)
Have a great day
Your answer is wrong.
Solution:
4(8+3.5+x)=183
x is the cost of 1 ticket
32+14+4x=183
4x=183-32-14
4x=137
x=137/4
x=34.25
!!!One ticket costs 34.25 dollars, NOT 3.5 dollars!!!
