Answer:
15$
Step-by-step explanation:
cost of 1 cookie = 10/6
cost of 9 cookies = 9* 10/6 = $15
Answer:
270
Step-by-step explanation:
360-90 =270 since the arc for xw is 90 then subtract the whole circle
K so you have to set 2 equations like this
x meaning the amount of adults
and y meaning the amount of kids
x+y=11
13.5x+8.25y=111.75
Then use substitution method and you get
x=11-y from the first equation
plug that in to the second and you get
13.5(11-y)+8.25y=111.75
Solve for y in that equation by distributing and then combining like terms
148.5 - 13.5y + 8.25y = 111.75
148.5 - 5.25y = 111.75
Then, you need to subtract 148.5 from each side and cancel the negatives
5.25y=36.75
solve for y and you get
36.75/5.25 = 7
y=7

The lcm of 4 and 9 is 36.
Step-by-step explanation:
AOD - since it forms a triangle and the sides of the triangle are radius of circle they are equal so ADO = DAO. to find AOD: 180⁰-36⁰-36⁰=108⁰.
ODC - first we find DOC :180⁰-108⁰=72⁰.since the other 2 sides of the triangle are equal we can find ODC by : 180⁰=72⁰+2x
2x=180⁰-72⁰
2x=108⁰
x=108⁰/2
x=54⁰
the other 3 right now i dont have an idea but if i think of it later i will comment it here.
ABC -its 120⁰ because it forms Z angles with CEF
CFD -first we find ODE which we do by : 90⁰-54⁰=36⁰. Then we find CED by : 180⁰-120⁰=60⁰.Then we find DCE by: 180⁰-36⁰-60⁰=84⁰.Then we find ECF by :180⁰-54⁰-84⁰=42⁰.And now we find CFD by : 180⁰-120⁰-42⁰=18⁰.
CAB -first we find BCA by : 180⁰-54⁰-84⁰=42⁰ or you can say it is equal with ECF because they are opposites of the same point.Then to find CAB we : 180⁰-120⁰-42⁰=18⁰ or you can say it is equal to CFD because they form Z angle.
