Write a single or compound inequality for each scenario.
a. the scores on the last test ranged from 65% to 100%.
b. to ride the roller coaster, one must be at least 4 feet tall.
c. unsafe body temperatures are those lower than 96℉ or above 104℉.

a)  0.65 ≤ ×  ≥ 1

b)  4 ≤ ×

c)  96 > ×    or        ×  >  104  

Step-by-step explanation:

We choose x as a variable for all cases

a)  from 65% to 100%                                  ⇒    0.65 ≤ ×  ≥ 1

b) At least 4 feet tall                                   ⇒      4 ≤ ×

c) lower than 96℉ or above 104℉            ⇒       96 > ×    or        ×  >  104  

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.
