From the pairs of x,y, if the set has two "x" of the same value, that is, "x" repeats, or an x-repeat, then is NOT a function
so, the group that doesn't have any x-repeats, is a function, now let's check
Answer:
This other side of the triangle is equal to about 11.7 cm
Step-by-step explanation:
In order to find out the third side of the triangle we will just use the Pythagoras Theorem.

Since we know the hypotenuse and we know one of the legs, in order to find the second leg we just substitute the values and solve the equation and so we get...


And so b ≈ 11.66190
I have seen some scales that convert units and some that don't
first is convert
the scale converts from smaller to bigger
?:1in
6ft/8in=0.75ft/1
scale is 0.75ft:1in
other one doesn't convert dimentions
6ft=6*12in=72in
72in:8in
9:1
that is most ilkely what teacher is looking for
scale is 9:1
72in:8in
