Step-by-step explanation:
1:9
1+9=10
(1×180)÷10= 18
(9×180)÷10=162
2x^2+7x-5+(-8x^2-3x+5)=-6x^2+4x.
The volume of a sphere of radius r is given by

For your given conditions, the volume of 1/2 a sphere becomes

Seems to match your 2nd choice:
... 1 over 24 over 322 over 7(83)
Answer:
Step-by-step explanation:
∠D = ∠B {opposite angles of parallelogram are equal}
∠D = 40°
In ΔDCA
∠DCA + ∠D + ∠CAD = 180 {Angle sum property of triangle}
57 + 40 + ∠CAD = 180
97 + ∠CAD = 180
∠CAD= 180 - 97
∠CAD = 83°
