Eduardwww [97]
Any multiples of 4.5:1.5 would work because being proportional just depends on whether you can reduce to get the same answer of the first triangle. You could do anything like 9m and 3m or 27m and 9m

Jay is cutting a roll of biscuit dough into slices that are 3/8 inch thick. If the roll is 101/2 inches long, how many slices ca
IceJOKER [234]
The roll of the biscuit is 101/2 inches long. It has to be cut into slices that are 3/8 inches thick.
Then
The number of slices = (101/2)/(3/8)
                                   = (101/2) * (8/3)
                                   = 808/6
                                   = 404/3
                                   = 134.66
So the biscuit dough can be cut into 134 slices approximately. A small part will be left. This is the only way to find out the number of slices the biscuit dough can be sliced into. Hope this helps you in understanding the way it is done.

Help!!!!!!!! i have no clue
siniylev [52]

Answer: Non-proportional

Step-by-step explanation:

The unit rate for the gas per gallon is $3.17. You want to find out if that is equal to the amount you would pay for 10 gallons at once. If you multiply the unit rate by ten, you would get 10 gallons = $31.70

So...you know that it is not proportional

It takes me into 30 minutes to walk from home to school when walking at 5 km per hour What is her average cycling speed If it ta
GREYUIT [131]

Answer:

10 km/h

Step-by-step explanation:

I'm not really sure about this but no ones answering your question and I wanna help.

So basically to calculate the average speed you need to divide the distance travelled by time taken

But you do not have the distance traveled. But it is mentioned that it takes u 30 minutes to walk from home to school when walking at 5 km/h so to find the distance all you have to do is... 30 x 5 = 150 km

Now that we have the time and distance all we have to do is find the average speed.

Average Speed = distance ÷ time

So 150 ÷ 15 = 10 km/h
