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.
Answer:
Perimeter = 16 units
Area = 15 squared units
Step-by-step explanation:
ABCD is a rectangle.
It's length l = 5 units
and width w = 3 units
Perimeter of ABCD = 2(l + w) = 2(5 + 3) = 2*8 = 16 units
Area of ABCD = 5*3 = 15 squared units.
Answer:
2.875 mi
Step-by-step explanation:
A scale factor (SF) is the ratio of two corresponding lengths in similar figures.
SF = actual distance/map distance = 5.75 mi/2 in
or 1 in = 2.875 mi
On the map, the distance from the library to the park is 1 in, so the actual distance is 2.875 mi.
Answer:
4 pencil & 2 ruler = $8
2 pencil & 4 ruler = $10
let the no. of Pencil be X and no. of ruler be Y
4x + 2y = 8
2x + 4y= 10
solving the equation by elimination method,
multiplying eq 2 with 2
4x + 2y = 8
4x + 8y = 20
subtracting,
- 6 y = -12
y = 2
2x + 4(2)= 10
2x + 8 = 10
2x = 10 - 8
2x = 2
x = 1
Cost of 3 ruler + 3 pencil
= 3(1) + 3(2)
= 3 + 6
= 9
