You can use models to estimate percent questions by estimating the locations of 50%, 75%, 40%, 6%, and 65% on the model..
Cost of 1 plant = $ p
Cost of 4 plants = $(4p)
Cost of a 10-gallon tank = $10
Cost of a water dish = $3
Total cost = 4p + 10 + 3 = 4p + 13
You need to include the question not just the explanation.
A=32, B=32, C=148, D=148
A parallelogram has 2 sets of equal angles and the total sum of all angles is equal to 360
Angles A,B are 32, to work out CD add angles AB then subtract that from 360
=360-64
=296
To work out each angle (CB) divide that by 2, therefore C and D are 148
HOPE THIS HELPS
Part A:
Electricity Company | Rate Charged | Rate Rounded |
Atlas Energy 12.065 12.070
Big City Light 9.138 9.140
Connex 9.143 9.140
Dynamon Power 9.707 9.710
ElectriCo 9.503 9.500
Part B:
Big City Light and Connex.
Part C:
Two companies can have the same rate when they are rounded because two numbers can be rounded to the same number although they are different numbers. For example; 9.138 and 9.143 can both be rounded to 9.140.
