72 triangles will be displayed I believe....

All you do is multiply 2 times 36 and you get 72. Because there are 2 triangles in one square, so 2*36.

Hope this Helps!

Ok, so there are 36 rectangle tiles which have three squares in each one that has two triangles in each so... 36 x 3 = 108
=============================================================
so there are 108 squares, now you multiply by 2 to get the triangles, which is 108 x 2 = 216 :)

Thats your answer! hope i helped :)

Honestly I can see an argument for 7 shelves or for 8 shelves. 

When you do the calculation; \frac{422}{59}=7.15 You get 7.15 shelves. Clearly you cannot have .15 of a shelf so the logician in me wants to say you need 8 shelves! 

But if the assignment is aimed estimation skills, (Which is what I assume is being implied by the title of the assignment), then the easier calculation of \frac{420}{60}=7 is probably what the teacher was hoping for.

You might have been accidentally been calculating \frac{59}{422} =.139. Remember division is NOT communitive! i.e.1\div2\neq2\div1.

From the image;
The first step was to see that 59 can not go into 4..resulting in the zero above the 4, multiplying 0 by 59 and subtracting 0 from 4. 

The second step begins by bringing down the 2, seeing that 59 can not go into 42..resulting in the zero above the 2, multiplying 0 by 59 and subtracting 0 from 42.

The third step begins by bringing down the 2, seeing that 59 can go into 422 7 times (I tested this on the right by a short multiplication problem)..resulting in the 7 above the 2, multiplying 7 by 59 and subtracting 413 from 42.

This process continues....

Lesechka [4]

Answer:

The Car.

Step-by-step explanation:

We need to find the unit rate for each vehicle to figure out who is traveling faster or slower.

Car: 600/20 = 30 ft per second

Motorcycle: 300/12 = 25 ft per second

So, the Car is faster
