A rational number is one that can be expressed as x/y. The first statement is false. All whole numbers are rational. They can always be expressed as x/1
Some rational numbers are not whole numbers. That's true. 4/7 is rational but not whole.
Some irrational numbers are not integers. I'm tempted to say this is true.
pi is irrational and it certainly is not an integer.
Answer
false
true
true.
Answer:
[c] The value of w cannot be a negative number.
[d] Substitution is used to replace the variable l with a value of 20.
[e] The subtraction property of equality is used to isolate the term with the variable w.
Step-by-step explanation:
To figure out which steps of the solution are true, let us solve.
2 l plus 2 w equals 62 -> 2l + 2w = 62
----
2l + 2w = 62
2(20) + 2w = 62 <- Substitution is used to replace the variable l with a value of 20.
40 + 2w = 62
2w = 22 <- The subtraction property of equality is used to isolate the term with the variable w.
w = 11
This means that the value of w is <em>not</em> 10 feet so the first option is incorrect. This shape is a rectangle, so the value of w cannot be 0. Since we cannot have a negative measurement, option three is incorrect. This leaves us with the last three options as our answer, shown by the work above.

Answer:
100
Step-by-step explanation:
Add all of the inches together including the parts you don't see.
one side is 9 inches. there are 8 sides. so 9x8. One side in the box is 7 inches. there are 4 sides. so 7x4. 9x8 + 7x4 is equal to 72 + 28.
72 + 28=100
765° = 45°
1485° = 45°
We get 2sin(45°) + tan(45°) + cot(135)
sin(45) = sqrt(2)/2
tan(45) = 1
cot(135) = -1
we get
2*[sqrt(2)/2)] + (1) + (-1)
= sqrt(2)
