You are considering purchasing a robot to you with household chores such as vacuuming. while you are researching options, you learn more about numeration and other bases. many electronics are programmed in base two. computers don't use ten digits but instead code things as 0 and 1. there are millions of little switches that are either on or off. the robot is programmed in binary numbers, or base two. the place values in a base two system are 1, 2, 4, 8, 16, etc. (powers of 2) instead of the base ten system place values of 1, 10, 100, 1000, etc. (powers of 10). how would the robot think of the number 16 in base two?

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

she would want to sell 10 full-year subscriptions and at least 9 half-year subscriptions to get a total of at least $300.
