Step-by-step explanation:
a)1.8kg=1.8*1000=1800g
b)6toys=1800
1toy=300g
c)4toys=4*300=1200g=1.2kg
The abscissa is the x-coordinate of the ordered pair and the ordinate is the y-coordinate. The ordered pair is therefore given to be,
(abscissa, ordinate)
or (x , y)
From the given, it is stated that the ordinate is three more than twice the abscissa. The ordered pair can therefore be written as,
(x, 2x + 3)
If x = -1 then,
y = 2(-1) + 3 = 1
Ordered pair : (-1, 1)
If x = 0
y = 2(0) + 3 = 3
Ordered pair : (0, 3)
Hence, the answer to this is either the first choice or the second choice which appears to be just the same.
Use Euler's formula for polyhedra: V - E + F = 2
vertices - edges + faces = 2
So edges = vertices + faces - 2 = 18 + 11 - 2 = 27.
Answer:
27 edges.
