Answer:
30 minutes to 120 minutes.
Step-by-step explanation:
$18 = 14 + 0.20(t)
- 14
4 = 0.20t
Divide 4 by 0.20
t = 20
0.20 * 20 = 4
4 + 14 = 18
Because it only charged her for texts after 450, its 450 + 20.
470. She sent 470 texts that month.
Answer:
17.8 cm³
Step-by-step explanation:
The radius of the roll is half the diameter, so is 9 mm. The length of the roll of 50 dimes is 1.4·50 mm = 70 mm. With these dimensions, we can use the formula for the volume of a cylinder:
V = πr²h = π(9 mm)²(70 mm) = 5670π mm³ ≈ 17,812.8 mm³
Perhaps a more convenient unit of measure is cm³. Each cm³ is 1000 mm³, so the volume of a roll of dimes is approximately ...
V ≈ 17.8 cm³
