Gracie wants to create a rectangular-shaped garden in her backyard. She has decided that the garden will be 20 by 16 feet long. If one bag of fertilizer only covers an area of 15ft², how many bags of fertilizer will gracie need for her garden?

she would need 22 bags of fertilizer.

Step-by-step explanation:

Gracie wants to create a rectangular-shaped garden in her backyard. The formula for determining the area of a rectangle is expressed as

Area = length × width

She has decided that the garden will be 20 by 16 feet long. This means the area of the rectangular-shaped garden is

Area = 20 × 16 = 320 ft²

If one bag of fertilizer only covers an area of 15ft², it means that the number of bags of fertilizer gracie will need for her garden is

320/15 = 21.33 bags

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

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
