If you are driving at a rate of 55 miles per hour, about how many feet per second are you traveling? 0.015 feet per second80.67 feet per second4840 feet per second290400 feet per second

1 mile = 5280 feet

 1 hour = 60 minutes

1 minute = 60 seconds

55/60 = 0.91666 miles per minute

5280 x 0.91666 = 4840 feet per minute

4840/60 = 80.67 feet per second

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
