C = 2(PI)r multiply 2 x 3.14 x (whatever the radius is!
p + 2 = 5 ==> p = 3
3p + 2 = p + 3 ==> 2p = 2 ==> p = 1
3k + 5 = 2k + 2 ==> k = -3 (niemożliwe; lewa strona wagi ma większą wagę)
2w + 10 = 4w + 7 ==> 2w = 3 ==> w = 3/2
d + 9 = 3d + 2 ==> 2d = 7 ==> d = 7/2
W drugim zadanie każda litera reprezentuje wagę jednego z obiektów. Na przykład 3k + 4 reprezentuje całkowitą wagę 3 kół i 4 ciężarów, każdy o wadze 1 kg.
Trzecie zadanie to tylko połączenie dwóch pozostałych.
Answer:
its 63

Step-by-step explanation:
Answer:
A. Soar radiation
Step-by-step explanation:
Blowing wind rotates the wind turbine and generates the energy called wind energy. More the speed of wind, more the energy can be generated.
That's how, wind energy depends on the speed of the wind and the speed of the wind is due to the pressure difference in various regions.
The zone having more solar radiation has low pressure and the zone having less solar radiation have high pressure of air and winds flows from high to low-pressure zone.
Therefore, the energy that generates wind comes from what source soar radiation.
Hence, option (A) is correct.
