Ram buys an article for $ 1800 and sells it at 10% loss. Find its selling price. *

Answers

Answer:

The answer is $180

Step-by-step explanation:

10% = 0.10

.10 x 1800 = 180

Function R gives the amount of rain measured by a rain gauge hours since it started raining. The amount of rain is measured in millimeters.

What does each expression or equation represent in this situation

a. R(3)

b. R(0.5)=14

Answers

Answer:

R(3) means that it has rained 3 millimeter and R(0.5)=14 means in 14 hours it has rained half a millimeter.

Step-by-step explanation:

The function R defines the amount of rain for a certain number of hours.

R(3) means the amount of rain in 3 hoursR(0.5) = 14 means the amount of rain in 0.5 hours is 14 millimeters

This function R can be represented as:

[tex]\mathbf{y = R(x)}[/tex]

Where:

y represents the amount of rain, and x represents the time

So, the meaning of R(3) is:

The amount of rain in 3 hours

While the meaning of R(0.5) = 14 is:

The amount of rain in 0.5 hours is 14 millimeters
