Step-by-step explanation:
(72)¹⁴³ ≡ x (mod 7)
Since 72 ≡ 2 (mod 7),
72³ ≡ 2³ (mod 7) ≡ 1 (mod 7).
Therefore (72)¹⁴³ = (72³)⁴⁷ * (72²)
≡ 1⁴⁷ * 4 (mod 7) ≡ 4 (mod 7).
The answer is A.
Answer:
48 tapes
Step-by-step explanation:
2/3 is given away
1/3 = 24
24 x 3 = 72
2/3 of 72 = 24 x 2

112÷65=1.7230769231×100=172. So there is about 173 students in 8th grade class
Answer:
Step-by-step explanation:
If the radius of the circle is equal to
and the area is given as 45, then
which simplifies to
and to the nearest tenth,
r = 3.9
Your answer would be -624 because 1-210-3= -212 then 3 times -212 +12= -624
