Answers:
C, D, E
Step-by-step explanation:
A rational number is a integer. It is also a terminating or repeating decimal.
A rational number can be written as a fraction of two integers.
Answer A is not correct because it's decimal never ends. It is also not repeating. A cannot be written as a fraction.
Answer B is not correct because the square root is not a whole number, or a perfect square. The square root has a non-terminating and non-repeating decimal, just like A. B cannot be written as a fraction.
Answer C is rational because it has a terminating decimal.
D and E are integers, which also can be written as fractions.
Out of the options given, C, D, and E have rational numbers, while all others do not.
The answers are C, D, and E.
Answer:
Step-by-step explanation:
Proper scientific notation means that there is only 1 number to the left of a decimal and everything else to the right of it. Also, because the number is initially less than 1, the exponent will be a negative one. We have to move the decimal 4 places to the right in order to get the 6 to the left of it, so in correct scientific notation format, we have
Answer:
The answer is No Solutions
Step-by-step explanation:
Since this is absolute value, we know the answer has to be positive, because distance has to be positive. We see it is negative, and that cannot be, so the answer is no solutions.
Answer:
Area of the shaded region= 
Step-by-step explanation:
Area of the shaded region= Area of the triangle- Area of the rectangle
Dimensions of the triangle:
Base= 40 inch
Height= 40 inch
Area of a triangle=
Area of the rectangle= Length*Width
Length=30 inch
Width=10 inch
Area:
Area of the shaded region= 
The roots to this equation i s either positive or negative five
