Step-by-step explanation:
Given c = longest of triange = 15m
Given b = short side of triangle = 9m
By pythagoras' Theorem,

I think that it's - positive linear association with one deviation
5 x 5 x 5
Expanded just means writing it out as you would solve it. So solving a cube would be multiplying the number by itself 3 times
The initial cost is 189.69. It is marked up 30%.
By simple calculations,
Final cost of the tablet computer = Initial price + 30% of marked price
= 189.69 + (30/100 x 189.69)
This gives us the net value of 245.7. Hence the price of the computer after it's been marked up will be 245.7
