Answer:

No, the number of sit-ups Anna does, are not proportional to the time she spends doing them.

Step-by-step explanation:

When Anna starts, she does a sit-up every 22 seconds. But, as she gets tired, each sit-up takes longer and longer to do.

So, no, the number of sit-ups Anna does, are not proportional to the time she spends doing them. his is because for being proportional, the decreasing or increasing rate should be constant but here, it is not.

Answer:

74º

Step-by-step explanation:

  • Ray TV bisects ∠RTS, so ∠RTV=∠STV=(16x-6)º
  • We also know that ∠RTS=(26x+18)º
  • So, (16x-6)º+(16x-6)º=(26x+18)º
  • We don't need parenthesis, 16x-6+16x-6=26x+18
  • Combine like terms, 32x-12=26x+18
  • Add, 32x=26x+30
  • Subtract, 6x=30
  • Divide, x=5
  • ∠RTV now is [16(5)-6]º=(80-6)º=74º
