Keri is simplifying 5·10−3.

which could be the first step to use when simplifying the expression?
a) 5 · 10−3 = 5(10)^1/3
b) 5 · 10−3 = 1/50^3
c) 5 · 10−3 = 1/50^1/3
d) 5 · 10−3 = 5(1/103)

The number of revolutions of two pulleys is inversely proportional to their diameters. if a 24-inch diameter pulley making 400 revolutions per minute is belted to an 8-inch diameter pulley, find the number of revolutions per minute of the smaller pulley.

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36
