what is the arc measure of ABC in degrees

283°

Step-by-step explanation:

The sum of the arc angles is 360°.

7y − 7 + 4y + 6 + 20y − 11 = 360

31y − 12 = 360

31y = 372

y = 12

The measure of arc ABC is the sum of arcs AB and BC.

4y + 6 + 20y − 11

= 24y − 5

= 24(12) − 5

= 283

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
