Bruno listens to podcasts for
two and a half hours a day.
write an equation where x is
the number of days and y is
the total number of hours.
what is the constant of
proportionality? in the problem above how many hours will bruno have listens after 12 days this is last three questions i need with will mark brainiest you so much these are 2 question the top is the first second is the bottom

the constant of proportionality is 2.5

the number of hours that

Bruno would have listened after 12 days is 30

Step-by-step explanation:

Let x represent the number of days.

Let y represent the total number of hours.

Bruno listens to podcasts for

two and a half hours a day.

Let k represent the constant of

proportionality. It means that

k = y/x = 2.5/1

k = 2.5

The expression becomes

y = 2.5x

Therefore, the number of hours that

Bruno would have listened after 12 days would be

y = 12 × 2.5 = 30 hours

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
