Frank is drawing a treasure map using a scale of 1 cm to 10 m. he wants to show that the treasure is buried 20 meters from a tree. how many centimeters should he show for this distance on the map?

2cm

Step-by-step explanation:

Using the initial scale (ratio) of 1 cm to 10m:

You can set up a proportion to solve for the amount of centimeters needed for 20 meters:

, where 'x' is the number of centimeters

Multiplying both the numerator and denominator by '2' in the initial ratio gives you a measure of 2 cm.

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
