A. Terms
b. 9
64 to 49 is -15, 49 to 36 is -13, 36 to 25 is -11, 25 to 16 is -9, so the next number is 16-7=9
complementary angles add up to 90°, so therefore we know that ∡A + ∡B = 90°, and also they are in a ratio of 3:6.

Answer:
is the root of 5 not equal why
Answer: 32
Step-by-step explanation:
Given: The energy needed for 1 hour of running for an adult 
Therefore. the energy needed for seven hours of running=
Since, he energy released by metabolism of 1 average candy bar 
Therefore, the number of candy bars an adult need to eat to supply the energy needed for seven hours of running.=
Hence, the adult need to eat 32 candies to supply the energy needed for seven hours of running.
