.28 if 1 was 100,and .28 was 2.8, then we divide 100 by 100 same for 2.8
Q = d - 12
q = 28 - d
d - 12 = 28 - d
d + d = 28 + 12
2d = 40
d = 40/2
d = 20 <== 20 dimes
q = d - 12
q = 20 - 12
q = 8 <== 8 quarters
Answer:
Step-by-step explanation:
3D space (x, y, z) = (10, 45, 57)
I will use x² + y² = (2D Hyp)² and (2D Hyp)² + z² = (3D Hyp)²
which is just x² + y² + z² = (3D Hyp)²
10² + 45² + 57² = (3D Hyp)²
100 + 2025 + 3249 = 5374 = (3D Hyp)² the destance from the origin
= 73.31 the destance from the origin
