The answer to the question is :
A) Mallard Population
The reason this is the answer is because the question asks for the term that best describes the TOTAL number of Mallards in the pond, and the right term, or phrase, would be Mallard Population.
Differences Between Rational and Irrational Numbers
The difference between rational and irrational numbers can be drawn clearly on the following grounds
1. Rational Number is defined as the number which can be written in a ratio of two integers. An irrational number is a number which cannot be expressed in a ratio of two integers.
2. In rational numbers, both numerator and denominator are whole numbers, where the denominator is not equal to zero. While an irrational number cannot be written in a fraction.
3. The rational number includes numbers that are perfect squares like 9, 16, 25 and so on. On the other hand, an irrational number includes surds like 2, 3, 5, etc.
4. The rational number includes only those decimals, which are finite and repeating. Conversely, irrational numbers include those numbers whose decimal expansion is infinite, non-repetitive and shows no pattern.
After reviewing the above points, it is quite clear that the expression of rational numbers can be possible in both fraction and decimal form. On the contrary, an irrational number can only be presented in decimal form but not in a fraction. All integers are rational numbers, but all non-integers are not irrational numbers.
Answer:
The answer to your question is 6.- B 7.- D
Step-by-step explanation:
Data
Parallelogram ACFG
6.-
m∠GAC = 112°
m∠ACF = ?
Process
These angles are supplementary, they measure the same.
∠GAC + ∠ACF = 180
-Substitution
112 + ∠ACF = 180°
-Solve for ∠ACF
∠ACF = 180° - 112°
-Result
∠ACF = 68°
7.-
m∠AGF = 2a + 10
m∠ACF = a + 20
The angles ∠GAC and ACF are equal, they measure the same.
∠GAC = ∠ACF
-Substitution
a + 20 = 2a + 10
-Solve for a
a - 2a = 10 - 20
-Result
-a = -10
a = 10
-Find ∠AGF
∠AGF = 2(10) + 10
20 + 10
= 30°
Answer:
1) 2
2) 4
3) 3
4) 1
Step-by-step explanation:
8/4 is 2
8/2 is 4
3/1 is pretty simply 3
And lastly (and kind of least)...
3/3 is 1
Hope this helped you out!
