J=(7x+13) K=(83-2x) and the sum of the measures of the angles is 141. What is the measure of each angle
natta225 [31]

Answer:

j=76 and k=65

Step-by-step explanation:

j + k = 141 \\ 7x + 13 + 83 +  - 2x = 141 \\ 96 + 5x = 141 \\ 5x = 141 - 96 \\ 5x = 45 \\ x =  \frac{45}{5}  \\ x = 9 \\ j = (7 \times 9 + 13) \\ j =76 \\ k = 83 - 2(9) \\  = 83 - 18 \\  = 65

The diameter of a sphere is 21.6 cm. What is the sphere's volume? Round to the nearest tenth, if necessary.
NeX [460]
By definition, the volume of a sphere is:
 V =  \frac{4}{3}  (\pi) (r ^ 3)

 Where,
 r: sphere radio
 Substituting values we have:
 V =  \frac{4}{3}(3.14)(( \frac{21.6}{2} ) ^ 3)

 V = 5273.99424
 Rounding the result to the nearest tenth:
 V = 5274.0 cm ^ 3
 Answer:
 the sphere's volume is:
 V = 5274.0 cm ^ 3
