Answer:
B.) 21.2 units
Step-by-step explanation:
Radius = Diameter divided by 2
So
Diameter = radius multiple by 2
Part A: divide the miles she biked in the amount of time she took. so, 21/4= 5.25. Her average speed is 5.25 miles per hour.
Part B: If she bikes at the same rate (21 miles in 4 hours), then she would take 8 hours to bike 42 miles because 21+21=42 and since she takes 4 hours to bike 21 miles, then it would take her another 4 hours to bike another 21 miles

Answer:
Step-by-step explanation:
4
Maximum amount to spend ≤ 65
Cost of dark roast coffee = $7.50
2 dark roast coffee= $7.50 * 2 = $15
Pumpkin Spice + dark roast ≤ amount to spend
Let pumpkin spice = x
Cost of pumpkin spice = $10.50
Dark Roast Coffee = y
10.50x + 2* 7.50 ≤ 65
10.50x + 15 ≤ 65
10.50x ≤ 65 - 15
10.50x ≤50
x ≤50 / 10.50
x ≤ 4.76
Number of pumpkin spice coffee that can be purchased is 4.
