The direct variation equation is:
d=kt
where d is the distance that the giraffe travels
k is the constant of variation
and t is time
Now we are told that the giraffe can travel 800 ft in 20 seconds, so we can solve for the constant of variation (k)
800=k(20) divide both sides by 20
k=40-------------and the units are ft per sec
So now we can write
d=40t
ck
d=40t
800ft=40*20 ft
800 ft= 800 ft
Hope this helps!
Let x is the <span>unknown number
</span><span>quotient of an unknown number and 12 : x/12
</span><span>49 more than the quotient of an unknown number and 12 : x/12 + 49
so equation:
</span>x/12 + 49 = 53
the answers is at the picture :)
Formula:
P = 2(L + W)
so
P = 2(32.55 + 12.50)
