Answer:
<h2>
<em><u>60</u></em></h2>
Step-by-step explanation:
tiny stuffed zebras(tsz)= $3
giant stuffed zebras(gsz)=$14
total sold=$208
208÷3=69.3recurring so that's incorrect as you cannot sell .3 of a zebra so keep going until you find the next whole number. (trial and error)
207÷3=69 but it cant be this as it is not the whole money made
208-14=194
194÷3=64.6recurring (cannot be this)
194-14=180
180÷3= 60 = answer as 60 tsz is $180 and add that to 2 gsz and that totals to 208 which is the total

Step-by-step explanation:
20/4 = 5
5^2 = 25
Answer:
a) 5.13beats/min
b) 2.82 beats/min
Step-by-step explanation:
Given the pulse rate of a person modelled by the equation y = 600x^-1/3 for 30≤x≤75
If the height is 39inches, the instantaneous rate of change of pulse rate for the heights will be expressed as;
y = 600(39)^-1/3
y = {600(1/39)}/3
y = 600/39×3
y = 600/117
y ≈ 5.13beats/min
The instantaneous rate for a 39 inches tall person is 5.13 beats per min
b) For a 71inches tall person, the beat rate will be expressed as;
y = 600(71)^-1/3
y = {600(1/71)}/3
y = 600/71×3
y = 600/213
y ≈ 2.82 beats per minute
The instantaneous rate for a 71 inches tall person is 2.82 beats per min
