Well, one set would be: everyone gets 66! Then, if you just start adjusting some scores, adding and subtracting the same amounts here and there, the total does not change, so the average does not change. For example, 66 66 66 66 66 ... 64 68 65 67 70 62 ...

The equation 0.11x = 66 means that 11% of some number is 66. Since you're looking for the amount of sales, you need to divide. Remember you're looking for a number much larger than 66. 0.11 times \$66 = \$7.26 so that can't be the amount of the sales.

Assuming there is no change in productivity.. In one hour, Thomas does 1/4=25% of the job, while Julia does 1/6=16.66%. Combined they would do 25%+16.66% = 41.66% of the job in 1 hour. So, 1/.4166= 2.4 hours

You are right Elisa. I get 2.66 ft. 101mph = (101/60)88 = 148.13 fps. 60.5/148.13 = .408 sec. h = 16t^2 = 15(.408^2) = 2.66 feet.

At 66.8% humidity on a 15C day, the air partial pressure is 66.8% of 1.69 kPa, or 1.13 kPa. That is 94.9% of the saturation pressure at 10 C. Therefore the relative humidity becomes 94.9% when the temperature drops to 10C
