Step-by-step explanation:
because VW || YZ, the 2 triangles are similar.
this is given by the rules of equal angles of intersecting lines with parallel lines. Z to V and Y to W would be such intersecting lines.
and therefore, the angle at W is the angle at Y, the angle at V is the angle at Z. and therefore both angles at A are equal.
so, for similar triangles the scaling factor between corresponding pairs of sides is the same for all sides.
e.g. the same scaling factor that converts 7.2 to 12, converts then also x to x+4.
7.2 × f = 12
f = 12/7.2 = 12/ 72/10 = 120/72 = 10/6 = 5/3
x × 5/3 = x + 4
5x = 3x + 12
2x = 12
x = 6
A to Y = x = 6
W to A = x + 4 = 6 + 4 = 10
Answer:
D, 0.19
Step-by-step explanation:
So first you add up all the candies
you’ll get 79 pieces of candy
So 4 pieces of green candy
So we can just subtract 4 from 79 you’ll get 75 pieces
It still works becuase we know that 4 pieces gone are green so the other candies still have the same amount
Now there are 14 red pieces
So 14/75
Now simplify that and you’ll Get
0.18666666
Now round that, 0.19
The difference between $0.20 and $0.60 is: 0.60 - 0.20 = $0.40
The rate of change in 4 years is $0.40
The rate of change in 1 year is $0.10
17 divided by 3 in order to solve it
