spin [16.1K]

Answer:

6

Step-by-step explanation:

A painter mixes 2 1/2 pints (2.5 pints) of yellow paint with 4 pints of red paint to make a certain shade of orange paint. The ratio of yellow paint to red paint is 2.5:4. In order to find the pints of yellow paint needed to be mixed with 10 pints of red paint, we will use conversion fractions.

10 red pints × (2.5 yellow pints/ 4 red pints) ≈ 6 pints (we round off to 1 significant figure)

adelina 88 [10]

Answer:

Period annuity is the answer.

Step-by-step explanation:

Period annuity or fixed period describes a financial product offered by insurance companies that, in return for an investment, provides fixed payments each month for a certain amount of time.

A period annuity pays income to the person for a specified period of time like ten years. The payments depend on the amount paid into the annuity and the length of the payout period.

Whereas, the lifetime annuity provides income for the remaining life of the person.

Therefore, period annuity or fixed period annuity is the answer.
