Answer:

17.156

Step-by-step explanation:

A rational number has has a terminating decimal expansion or a decimal expansion of non-terminating repeating digits. Here, the decimal expansion is terminating, so it is a rational number.

Answer:

C. 17.156

Step-by-step explanation:

A rational number is any number that can be expressed as a fraction. So for example, since \sqrt{2} cant be expressed as a fraction, it isn't rational. A number like 1.25 on the other hand IS rational as it can be expressed as \frac{5}{4} or \frac{125}{100}.

Option C can be expressed as \frac{17156}{1000}, so it must be rational.

- Note that if a number has a finite amount of digits after the decimal (ie it doesn't go on forever like option B), it can be represented as a fraction and thus is rational.

4. Can two lines be parallel and perpendicular? Explain.
lidiya [134]

Answer: No

Step-by-step explanation: First, we need to understand that parallel lines are coplanar lines that do not intersect. On the other hand, perpendicular lines are lines that intersect at a right angle.

However, lines can't be both parallel and perpendicular because they either intersect each other at a right angle or never intersect.

So no, two lines can't be both parallel and perpendicular.

Write the equation of the line that includes the point (1,5) and has a slope of 3 in standard form.
Ymorist [56]

Answer:

-3x + y = 2

Step-by-step explanation:

The slope is 3. So the coefficient of x is 3.

when x = 1, y = 5.

So 3*1 + c = 5

So c is 2.

So y = 3x + 2

Therefore, taking 3x to the LHS, we get,

-3x + y = 2

Hope it helps ;)

If the tax rate is 9.5%. determine how much tax you will need to pay on your order
7nadin3 [17]

Answer:

In order to calculate the sales tax of an item, we need to first multiply the pre-tax cost of the item by the sales tax percentage after it has been converted into a decimal. Once the sales tax has been calculated it needs to be added to the pre-tax value in order to find the total cost of the item.
