Answer:
24.8 mph
Step-by-step explanation:
as we know if one sailed north and another east, the angle with respect to the port will be 90 degrees
This means that the distance of each ship to the pier can be the legs of a rectangular triangle
The distance of a ship from the other would be represented by the hypotenuse
h: Hipotenuse
c1: leg 1
c2: leg 2
By Pythagoras we know that the hypotenuse is equal to
h = √(c1^2 + c^2)
if we replace with the values we have left
h = √(18^2 + 17^2)
h = √(324 + 289)
h = √613
h = 24.758
we round a decimal place
h = 24.8
Looks like A is the answer.
Answer:
Market price of set = 25.14
Step-by-step explanation:
Given:
Discount percentage = 20%
Service charge = 10%
GST = 7%
Amount pays = 23.54
FInd:
Market price of set
Computation:
Assume;
Market price of set = a
Market price of set after discount = a(1-20%)
Market price of set after discount = 0.80a
Market price of set after discount + (Market price of set after discount)(Service charge) + (Market price of set after discount)(GST) = Amount pays
0.80a + (0.80a)(10%) + (0.80a)(7%) = 23.54
0.80a + 0.08a + 0.056a = 23.54
0.936a = 23.54
a = 25.14
Market price of set = 25.14
