What number are you thinking of?

Try it! Suppose the number I'm thinking of is 49.


The product of 49 and 7 is 343; we subtract 3 from that, obtaining 340.


Divide this 340 by 13: 340/13.


Double this quotient: 680/13

680 + 390

Add 30 to this result: 680/13 + 30 = ------------------ = 1070/13

13


Sadly, this is not 50, as we'd hoped.

Why don't you try doing this yourself? Would you do anything differently from the way I did it?

What number goes on top and how do you solve it.
vekshin1
So basically, each number is equal to the two numbers below it added together.

See, 7 = 3+4, 8 = 5 +3, etc.

So, the top would be 16 + 17.

16 + 17 = 33

So 33 goes on top.

A city planner wants to build a road perpendicular to D Street. What is the slope of the new road?
Romashka-Z-Leto [24]

Answer:

The slope of the new road is 0.

Step-by-step explanation:

  • the slope of d street line is tan(90)

[if the angle made by a line with x axis is \alpha then, the slope of that line will be tan(\alpha) ]

  • here, the angle made by the d street line with x axis is 90 degrees.
  • if a road is to be built which is perpendicular to d street , it should make 0 degrees i.e, it should be parallel to x axis .
  • so, the slope of new road will be tan(0) = 0
