Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
The sum of the two positive integer a and b is at least 30, this means the sum of the two positive integer is 30 or greater than 30, so we write the inequalities as below.
The difference of the two integers is at least 10, if b is the greater integer then we subtract integer a from integer b, so we write the inequality as below.
Therefore, the following system of inequalities could represent the values of two positive integers a and b.
Answer:
Weakest value = 0.0196
Strongest value = 0.5929
Step-by-step explanation:
Given:
Choices
0.691
-0.14
-0.24
-0.77
Computation:
0.691² = 0.477481
-0.14² = 0.0196
-0.24² = 0.0576
-0.77² = 0.5929
Weakest value = 0.0196
Strongest value = 0.5929
