Please help me I'm confused .-.

write a compound inequality for each situation


14. Children and senior citizens receive a discount on tickets at the movie theater. To receive a discount, a person must be under 10 years old, or 65 years or older.

15. The scores on the last test ranged from 65% to 100%.

16. Mercury is one of only 2 elements that are liquid at room temperature. Mercury is nonliquid for temperatures less than -38°F or greater than 673.8°F. Write a compound inequality for the temperatures at which mercury in nonliquid.​

Answer 1

Too ride the roller coaster, one must be at least 4 feet tall.

Explanation:

Answer 2

14)A compound inequality is
`10>x\geq 65`

15)A compound inequality is
`65\% <x< 100\%`

16)A compound inequality for the temperatures at which mercury in nonliquid. is
`-38^(\circ) F>x> 673.8^(\circ)F`

Explanation:

14)

Let x be the age of person

We are given To receive a discount, a person must be under 10 years old, or 65 years or older.

So,
`x<10` or
`x \geq 65`

So, a compound inequality is
`10>x\geq 65`

15) Let x be the percentage scored

We are given that The scores on the last test ranged from 65% to 100%.

So,
`65\% <x< 100\%`

So, a compound inequality is
`65\% <x< 100\%`

16)

Let x be the temperature

We are given that Mercury is nonliquid for temperatures less than -38°F or greater than 673.8°F

So,
`x< -38^(\circ) F` or
`x > 673.8^(\circ)F`

`-38^(\circ) F>x> 673.8^(\circ)F`

So, a compound inequality for the temperatures at which mercury in nonliquid. is
`-38^(\circ) F>x> 673.8^(\circ)F`
