Speed is the rate of distance over time.

<em>The speed of the boat is 13mph south-west</em>

Given

<em />v_1 = 12mph<em> --- west</em>

<em />v_2 = 5mph<em> -- south</em>

<em />

The speed is illustrated with the attached image

Because both speeds act at a diagonal, the speed (v) of the boat is calculated using Pythagoras theorem as follows:

v^2 = 12^2 + 5^2

v^2 = 144 + 25

v^2 = 169

Take square root

v = \sqrt{169

v = 13

<em />

<em>Hence, the speed of the boat is 13mph south-west</em>

484 + 676 ?=? 1156
1160 ?=? 1156
This is NOT TRUE so it is not a right triangle.

5x must be 50, as 50-6=44

50 divided by 5 is 10, so 10x

A $32 item is marked as 20% off. What is the sale price?
Natasha_Volkova [10]
$25.60

20%=.2
since it's 20% OFF, you want to get rid of .2 of the 32.
so 1-.2=.8
and .8 x 32 = 25.60
