Answer:
rational: 4¾, ¼, -0.9
whole: 8
integers: 8, -16
Step-by-step explanation:
rational numbers are numbers that can be expressed as a fraction. (-0.9 = -9/10)
whole numbers are numbers that do not have a fraction but they do not include negative numbers.
integers are numbers that can be expressed as a whole number with no fractions.

Answer:
W = 54
Step-by-step explanation:
w shares the same vertex with the 54° angle so they have the same size.
Answer:
B) 686 cubic units
Step-by-step explanation:
If one cube has a side length of 7, then it equals to 343 cubic units. Since there are 2 cubes, this translates to 686 cubic units.
The vertex form of equation of a parabola:
(h, k) - vertex
We have the vertex (-0.5, 2.3). Therefore h = -0.5 and k = 2.3.
Substitute:
We have the point (5, 2.75). Put the coordinstes of the point to the equation of parabola:
