To get whether they are equal you have to cross multiply the numbers 18x16 and 48x3
48x3= 144
16x18= 288
144 is not equal to 288.
Therefore the rates aren’t equivalent.
Answer:
6.2 hours
Step-by-step explanation:
d=rt where d is distance, r = rate and t - time
12.1 = 1.96t
Divide each side by 1.96
12.1/1.96 = 1.96t/1.96
6.17346 = t

Answer:
Pentagon (the 5 sided shape) = 1
Cross-looking shape = 6
Star = 8
Square/Rectangle = 5
Hope this helps!
The acceleration will be evaluated as follows:
s(t)=(2t+1)^(1/2)
the velocity will v(t) is given by:
v(t)=s'(t)=1/2*2(2t+1)^(-1/2)
v(t)=(2t+1)^(-1/2)
the acceleration will be given by:
a(t)=v'(t)=s"(t)=-1/2*2(2t+1)^(-3/2)
a(t)=-(2t+1)^(-3/2)
thus to evaluate a(t) at t= 4 sec we have:
a(4)=-(2*4+1)^(-3/2)
simplifying this we get:
a(4)=-(9)^(-3/2)
a(4)=-1/27 ft/sec^2
