Answer:
Hi! Your answer is m = 19
Step-by-step explanation:
<em><u>~use the slope formula to find the average rate of change~</u></em>
100 cm = 1 m => 1 cm = 1/100 m so, 86000 cm = 86000 * (1/100) m = 86000/100 m = 860 m now, 1000 m = 1 km => 1 m = 1/1000 km so, 860 m = 860 * (1/1000) km = 860/1000 km = 0.86 km so, 86000 cm = 0.86 km
Answer:
250
Step-by-step explanation:
copper: zinc : total
2 1 2+1 =3
We have 750 brass
750/3 = 250
Multiply each by 250
copper: zinc : total
2*250 250 3*250
500 250 750
divide the annual rate by 12 because there are 12 months in a year.
