A10 foot ladder is leaning against a tree the bottom of the ladder is 6 ft away from the bottom of the tree proximately how high up the tree does the top of the ladder reacha: 4 feetb: 6 feetc: 8 feetd: 16 feet

Looking at the picture it is just a triangle with a hypotenuse of 10 (the ladder) and the bottom side of 6 (distance from the ladder to tree). All you have to do now is the Pythagorean theorem: a^2 + b^2 = c^2

10^2 - 6^2 = b^2

100 - 36 = b^2

64 = B^2 now square root both sides.

Answer is C. 8 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
