The weather report predicts rain for the next 3 days. Assuming the prediction is true and there is no rain on the other days of the week, what is the ratio of rainy days to the total number of days in the week?(1 point)
Answered by GPT 3.5
The constant of proportionality can be found by dividing the number of words typed by the time taken to type them, or by dividing 368 by 8.

So the constant of proportionality, k, is 46.

To find the sale price of the Xbox, we need to subtract the discount from the original price.

The discount is 20% of $399, which is (20/100) * $399 = $79.80.

Subtracting the discount from the original price gives us the sale price:

$399 - $79.80 = $319.20.

Therefore, the sale price of the Xbox is $319.20.

If the weather report predicts rain for the next 3 days, we can assume that there are 3 days of rain in the week.

Since there are 7 days in a week, the ratio of rainy days to the total number of days in the week is 3:7.
