patriot [66]

Answer:

s = \frac{3}{10} m

Step-by-step explanation:

Given s varies directly with m then the equation relating them is

s = km ← k is the constant of variation

To find k use the condition s = 9 when m = 30 , thus

9 = 30k ( divide both sides by 30 )

k = \frac{9}{30} = \frac{3}{10}

s = \frac{3}{10} m ← equation of variation

Which division problem is represented with this model? 14÷3 15÷3 13÷2 15÷4
stich3 [128]

Answer:

The division model is 15 ÷ 3

Step-by-step explanation:

Required

Interpret the division model

A division model is of the form: Dividend ÷ Divisor

In the attached figure (in the question), there are 5 vertical partitions.

This vertical partitions represents the result of the model

Also from the question attachment;

The horizontal partitions on the left, if traced to the right side of the diagram means that each vertical partition is divided into 3 and this represents the divisor of the model.

So, we have:

Divisor = 3

To get the quotient of the model, I'll make use of my attached file.

Counting the number of boxes, we can see that there are 15 boxes in total.

So, we have:

Dividend = 15

<em>Hence, the division model is: 15 ÷ 3</em>
