Answer: Sabrina read 65 pages on the second and third days
Step-by-step explanation:
45 + 2x = 175
45 - 45 + 2x = 175 -45
2x = 130
2x/2 = 130/2
x = 65
CHECK: 45 + 65 +65 = 175

Answer:
Step-by-step explanation:
hello : note 297 no 279
297 =3×99
99 = 3 ×33
33=3×11
this the geometric sequence. ( comon : 3)
the nth term is : An = A1 × r^n when : r = 3 and A1 =11
if n = 19 A19 = 11×3^19
Answer:
0.5158
Step-by-step explanation:
The exponential decay of a given material is used to describe the process by which a material decreases in size and amount over a specific period of time. The material will decay with respect to its decay factor. Therefore, if the 10-hour decay factor is approximately 0.2661, the 5-hour growth/decay factor will be: (0.2661)^(5/10) = (0.2661)^0.5 = 0.5158.
