The equation d=rt is used to calculate distance, rate, or time, where d is the distance (in yards), r is the rate (in yards per minute), and t is the time (in minutes). Consider the statements below that describe the walking rates for three people. Graph the equation that represents the rate of the fastest person. Jordan walks for 4 minutes and goes 200 yards.

Jack walks a rate of 55 yards per minute.

Lily walks 180 yards in 3 minutes.

Use the discriminant to describe the roots of each equation. then select the best description. 2m2 + 3 = m double root real and rational roots real and irrational roots non-real roots

If sr is 4.5cm and tr is 3cm, what is the measure in degrees of angle s?

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
