Use the table to answer the question. The table shows the relationship between the number of Calories Darrel burns while Kayaking and the number of minutes he leaks.
Minutes Calories Burned
50
200
100
400
150
600
200
800

4 calories

Step-by-step explanation:

From the table given, the number of calories burnt shows a proportional or linear relationship with the minutes spent while kayaking.

Calories burnt is proportional to the minutes spent.

The calories burnt in 1 minute = number of calories burnt ÷ the number of minutes spent at any given interval.

Since 200 calories are burnt in 50 mins, therefore:

Calories burnt in 1 minute =

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
