Question

At a construction site there are a number of concrete bricks. We know that 6 concretebroks weigh 90 kilograms. Assuming each brick weighs exact same, fill out the table belowusing equivalent ratos.# of Concrete BlocksWeight (kilograms)What is the proportional relationshipbema represented?What is the constant of proportionality?360What volue belongs next to the in thetable? What does it mean in context of

Answer 1

We know that 6 concrete broks weigh 90 kilograms so we can fin hoy much weigh each brok like this:

`(90)/(6)=15`

Now we can complete the table with this factor so:

`\begin{gathered} 1\to15 \\ 2\to30 \\ 3\to45 \\ 4\to60 \\ 5\to75 \\ 6\to90 \\ 7\to105 \end{gathered}`

the constant of proportionality will be:

`k=(y)/(x)=(105)/(7)=15`

And the number next to the one will be 15 and that means that 1 brick weigh 15 kilograms
