Answer:
Associative
Step-by-step explanation:
3 x 4 =12 and 12 x 2 =24
Since there aren't any exponents the x,y, and z gets added together giving you 24 xyz
Answer:
C) A, J, D, and G
Step-by-step explanation:
Co-planar means that all of the points lie within the same plane, by using the process of elimination you can discover that option C is the only one that does not have all 4 points within the same plane.
Answer:
5 cm
Step-by-step explanation:
Perimeter of a semicircle is :
P = πr + 2r
P = r(π + 2)
25.71 = r(3.14 + 2)
25.71 = r(5.14)
Divide both sides by 5.14
25.71 / 5.14 = r(5.14) / 5.14
5.0019455 = r
Hence, radius of semicircle = 5 cm
Speed is the rate of distance over time.
<em>The speed of the boat is 13mph south-west</em>
Given
<em />
<em> --- west</em>
<em />
<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:



Take square root


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