Answer:
The marked price of the watch is $2,702.27.
Step-by-step explanation:
Since allowing 20% discount on the marked price of a watch, the value of the watch will be Rs. 2378, to determine, if the VAT of 10% is added, it's marked price, the following calculation must be performed:
1 - 0.2 = 0.8
0.8 x 1.1 = 2378
0.88 = 2378
0.88 = 2378
0.8 = X
0.8 x 2378 / 0.88 = X
1,902.4 / 0.88 = X
2,161.81 = X
0.8 = 2,161.81
1 = X
2,161.81 / 0.8 = X
2,702.27 = X
Therefore, the marked price of the watch is 2,702.27.
False because the obtuse angle is to large to complement the right angle to diffrent angles can not be both of their compliments
P(B) = 0.75.
For independent events, P(A and B) = P(A)*P(B). This gives us
1/8 = 1/6(x)
Divide both sides by 1/6:
1/8 ÷ 1/6 = x
1/8 × 6/1 = x
6/8 = x
3/4 = x
0.75 = x
