Hello Suzi, 17 girls planting 51 trees in one day ==> 1 girl can plant 51/17 = 3 trees per day. Now divide that by 24 hrs in a day to get: 1 girl can plant 3/24 = 1/8 of a tree in 1 hr. Thus,
Hello Lexi, This can be done with only one variable, but since you mentioned elmination, I gather you need to use two variables, so... Let x=$ that increased by 6% and y=$ that increased by 9%
Hello John, The equation governing the motion of an object subject to acceleration is: y(t)=(1/2)at^2+vot+yo, where a=the acceleration, vo=initial velocity, yo=initial position In this case: a=g=-32
Hello Maggie, The rational root theorem tells us that the possible rational roots of a polynomial with integer coefficients are factors of the constant term divided by factors of the leading coefficient
Hello Angela, I think you mean "is pi still irrational (not perfect) if expressed in another base"...yes? A perfect number is a whole number whose sum of proper divisors equals itself. For example
