Correct Answer: 4.5 cm²Two triangles of different sizes make up the logo. We are to find the difference in the areas of these triangle. Smaller triangle has a base of 2 cm and height 6 cm. Larger triangle has the base of 3 cm and height 7 cm.
Area of the triangle =

x Base x Height
So,
Area of smaller triangle =

cm²
Area of larger triangle =

cm²
The difference in the areas of triangles = 10.5 - 6 = 4.5 cm²<span />
The minimum electric rate in cents per kwh for which the 12-year total cost will be less for the first freezer is 8.61 cents
<h3>How to calculate the rate?</h3>
Let x = minimum electric rate (Cents/kWh)
Total months in 12 years is 12*12 = 144 m
1st freezer
Total cost over 12 years is
623.95 (cost) + (90 kWh/m)*(144 m)(x/100 $/kWh)
= 623.95 + 129.6x
2nd freezer
Total cost over 12 years is
500 + 100*144*(x/100)
= 500 + 144x
For the 1st freezer to cost less over 12 years,
623.95 + 129.6x < 500 + 144x
123.95 < 14.4x
8.61 < x
The minimum rate is 8.61 cents per kWh

Answer:
b = 8
Step-by-step explanation:
-11 - 5b = -6b - 3
add 11 to both sides:
-5b = -6b + 8
add 6b to both sides:
-5b + 6b = 8
simplify:
b = 8
