To find out the cups, total jug volume should be divided by 0.25 litre.
4.5/0.25
18 cups
82 I think that’s the answer because that’s my opinion if it’s wrong I don’t know what to tell you
<span>5[8 - (9x - 7)] + 6x = 0
5[8 -9x + 7] + 6x = 0
5(15 -9x) + 6x = 0
75 - 45x + 6x = 0
-39x = -75
39x = 75
x = </span>
= 1.923076923076923 ≈ 1.92
<span>Assume 11^10 - 1 = 0 (mod 100) (i.e. 11^10 - 1 is divisible by 100).
11^10 - 1 = 0 (mod 100)
11^10 = 1 (mod 100)
(11^2)^5 = 1 (mod 100)
(121)^5 = 1 (mod 100)
(21)^5 = 1 (mod 100) [the remainder of 121 divided by 100 is 21]
(21^2)^2(21) = 1 (mod 100)
(41)^2(21) = 1 (mod 100)
81(21) = 1 (mod 100)
1701 = 1 (mod 100)
∴ 11^10 - 1 is divisible by 100.</span>
