Several students form a circle by standing next to each other. Samantha and Aaron are directly across from each other and are approximately 30 feet apart. If each student takes up about 4 feet of the circle, how many students are in the circle? Use 3.14 for π.

24 students

Step-by-step explanation:

Since students on opposite sides of the circle are 30 feet apart, the circumference of the circle is πd≈94.2. Since each student takes up 4 feet of space, 94.2/4=23.55 which we can round to 23 or 24 students.

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
