A11-foot ladder is leaning against a building, with the base of the ladder 6 feet from the building. how high up on the building will the top of the ladder reach? round to the nearest tenth

9.2 feet

Step-by-step explanation:

This is a Pythagorean theorem question

The ladder is the hypotenuse or c

the distance from the wall is a leg or a

and the wall is the other leg or b

a² + b² = c²

6² + b² = 11²

36  + b² = 121

-36             -36

          b² = 85

         √        √

          b = √85

           b = 9.2 feet

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
