Write how you would use numbers to investigate each object

For the Octopus we can use the number to find the total number of limbs. We may also use numbers to find the swimming speed of the octopus.

For the second diagram given to us we can use numbers to find the volumes of the two containers and see if transferring any liquid from the first container to the second one will lead to spilling due to volume mismatch or not.

For the last diagram we can use numbers to find the height, width, breadth, in other words, dimensions of the scooter. We may also use numbers to find the speed of the scooter.

8 miles

Step-by-step explanation:

Given:

To take a taxi initial cost = $ 3.00

Per mile cost =  $ 2.00

Total spent = $20

Tip Given = $ 1

To find:

Total miles traveled=?

Solution:

Now the total cost f the ride was $ 20

As we see that initial cost for all the trips would stay the same

Let someone travels x miles

then according to the given

Initial cost + 2 * miles traveled + tip = total cost

Putting from the given values it becomes

3 + 2 * x + 1 = 20

Now we have to find x here which is the total miles traveled

solving the above equation

3+1+2x=20

4+2x=20

2x=20-4

2x=16

dividing both sides by 2

x =8 miles

so total miles travelled by the person is 8 miles
