Answer 2

thats not right it says if her heart rate should be between 140 and 160 beats per min what should the lower and upper numbers be for 10 seconds?

Answer 3

Yeah. Divide those by 6.

Answer 4

\[140 \le X \le 160\]60/10=6\[\frac{140}{6}=23.3\]\[\frac{160}{6}=26.7\]\[23.3 \le x \le 26.7\]

she clocks her pulse for 10 sec while exercising what should the number of beats be ? the num of beats in 10 sec should be between blank and blank
hint round to the nearest whole number

Answer 10

Divide 143 and 164 by 6 again.

Answer 11

\[\frac{x}{10}=\frac{143}{60}\]\[60x=143*10\]\[x=\frac{143}{10}=23.83\]
\[\frac{x}{10}=\frac{164}{60}\]\[60x=164*10\]\[x=27.33\]round\[24 \le x \le 27\]
