7. Five swimmers entered a competition. Four of the swimmers had their turns. Their scores are 9.8, 9.75, 9.79 and 9.81 seconds respectively. About what score should the fifth swimmer get in order to win the competition. Explain your answer.

We must order these decimals from least to greatest. Then we must determine how the least compares with the winning score.

9.80 -> 3

9.75 -> 1

9.79 -> 2

9.81 -> 4

The least decimal is 9.75. Now we must determine how 9.75 compare with the winning score.

The last swimmer must get a score less than 9.75 seconds in order to win.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
