Cassandra is a lifeguard and spots a child drowning 30 meters along the shore and 70 meters from the shore to the child. Cassandra runs along the shore for a while and then jumps into the water and swims from there directly to the child. Cassandra can run at a rate if 3 meters per second and swim at a rate if 1.1 meters per second. How far along the shore should Cassandra run before jumping into the water in order to save the child?

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

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
