1992- a gallon - 1.23dollars
yesterday - 2.19 dollars
2.19dollars - 1.23 dollars = 0.96 dollars
percentage increase is (0.96 / 1.23) x 100 = 78.0%
See attached graph.
The y-intercept is (0, 1), since the line is at that point when it intersects with the y-axis.
The common ratio is 1/4, since the y value multiplies by 1/4 for each unit on the x-axis.
The diagonals of a rhombus bisect each other at right angles, therefore m∠BEC=90°
9z + 45 = 90
9z = 90 - 45
9z = 45
z = 45/9
z = 5
Answer:
5/6
Step-by-step explanation:
The "first" dice can land on any number, so there are 6 choices. The "second" can not be the same number as the first one. So there are 5 choices. We multiply to get 6*5=30 ways to roll a different number. There are 6*6 total ways so the probability is 30/36 which simplifies to 5/6.
As a fraction it’s 48 7/10
As a percentage it’s 4870%
