Answer:
Step-by-step explanation:
It would be greatly appreciated if you gave me the brainlest
Idk use a calculator to find the sum of the answer
The area of the 120° sector is
.. Asector = (1/2)r^2*θ . . . . . . . angle in radians
.. = (1/2)*(24 m)^2*(2π/3)
.. = 192π m^2
The area of the white triangle in that sector is
.. Atriangle = (1/2)r^2*sin(θ)
.. = (1/2)*(24 m)^2*(√3)/2
.. = 144√3 m^2
The area of the shaded segment is the difference of these
.. Asegment = Asector -Atriangle
.. = (192π -144√3) m^2
The 2nd selection is appropriate.
So for every one cup of pretzels (1p)
You have three cups of chex (3c)
The ratio between pretzels and chex is 1p:3c
Thus, changes in 1 is proportional with changes in 3.
You need a total of 12 cups of party mix. The sum of the ratio 1 cup of pretzels and 3 cups of chex is 4.
So you would need 3 cups of pretzels and 9 cups of chex for the ratio to equal a sum of 12.
Thus the answer is 3p:9c
