If Erick does a job in 78 hours and Tracey does a job in 91 hours, how long will it take them to do the job together? \( \square \) hours

5. The value of the equation is closest to which of the following? \( \frac{873.5 \times 4.72}{59.6} \) A. 75,000 B. 7,500 C. 750 D. 75

1. Divide \( 18,102 \div 7 \)

The resting heart rate \( \left(H R_{\text {rest }}\right) \) is the number of times a heart beats per minute \( (\mathrm{bpm}) \). An average person's \( H R_{\text {rest }} \) is \( 60-90 \mathrm{bpm} \). Problems can result when a person's \( H R_{\text {rest }} \) is below 60 bpm or above 100 bmp . However, professional athletes and meditators can have \( H R_{\text {rest }} \) as low as 40 bpm due to their hearts' ability to pump blood efficiently. As of 2012 , the world's lowest verified \( H R_{\text {rest }} \) was 27 bpm for Martin Brady of the \( U K \). \( H R_{\text {rest }} \) is rarely found by checking a person's pulse for a full minute. More commonly, the pulse is measured for \( 5,6,10,12 \) or 15 seconds and then multiplied by the appropriate factor of 60 . Question 1 If you were to check Martin Brady's pulse for 5 seconds, how many beats would you expect to count? (assuming his world record rate)

lame: he grocer has 173 green apples and 197 red apples. How many apples does he grocer have?
