Evaluate each formula below for the given values of the variables. Find each
answer at the bottom of the page and cross out the letters above it. When you
finish, the answer to the title question will remain.
d=rt
(2) V= (wh
3) P=2+2w
| d = n(n − 3)
5 V=P(1 + rt)
(6) s=4.9t²
P= PR
(8) A=2w² + 4hw
where d is the distance traveled by an object moving at speed r in
time t. Find d if
r = 52 m/sec, t = 8 sec.
where V is the volume of a rectangular solid with length , width
w, and height h. Find V if
= 12 cm, w = 5 cm, h= 3.5 cm.
where d is the number of diagonals of a polygon with n sides.
Find d if
n = 20.
where P is the perimeter of a rectangle with length and width w.
Find P if
€ = 16 km, w = 7.5 km.
diagonals
where V is the value of an investment of P dollars, invested at
simple interest rate r for time t. Find V if
P = $500, r = .08 per year, t = 3 years.
where P is the power in an electrical circuit with current I and
resistance R. Find P if
/= 12 amperes, R = 2 ohms
$
where s is the distance in meters a free-falling object travels in t
seconds. Find s if
t = 4 sec.
