Andy is making paper boxes of different sizes. The supplies are limited, therefore, Andy restricted the volume of each box to 240 cubic inches or

less and the base area to exactly 30 square inches. Find the range of the height, h.

0 < h ≤ 8 inches

Step-by-step explanation:

The volume of each box is given by the base area multiplied by the height.

If total volume must not exceed 240 cubic inches, then:

Since no minimum volume was set, the height can range from any value greater than zero to exactly 8 inches:

0 < h ≤ 8 inches

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
