The answer is $70 so D
Because $59.5 is 85% of the original price, use 59.5/0.85 to find the original price
Answer:

Step-by-step explanation:
V=L×W×H
=3½in×1⅞×2¾
=3×2+1/2in × 1×8+7/8in × 2×4+3/4in
=7/2in × 15/8in × 24/4in
=2520/64 incube
so it's you tern to change into mixed fraction
sorry for that
but if it's helpful ❤❤

Answer:

Step-by-step explanation:
Let the function of quantity in the lung of air be A(t)
So 
so, A(t) = Amax sin t + b
A(t) = 2.8t⇒ max
A(t) = 0.6t ⇒ min
max value of A(t) occur when sin(t) = 1
and min value of A(t) = 0
So b = 0.6
and A(max) = 2.2

at t = 2 sec volume of a is 0.6
So function reduce to

and t = 5 max value of volume is represent
so,

when t = 5

so the equation becomes
