Sam can type 368 words in 8 minutes. What is the constant of proportionality that relates the number of words typed, y , to the number of minutes it took to type, x ? (Remember that constant of proportionality is k = y/x )(1 point)
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.
An XBOX 360 regularly sells for $399. It is on sale for 20% off. What is the sale price of the XBOX?
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.
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)
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.
