Answer: 2.7 is the decimal for 2 7/10
So a disc is a circle and the formula for the area of a circle is
so 3.14*6^2
=3.14*36
=<span>113.04
area=113cm^2</span>
Answer: x=number of rides
36 rides
Step-by-step explanation:
The linear function that gives the monthly cost E for x > 300 is given by:
E(x) = 44 + 0.04x.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
When x > 300, we have that:
- The base rate of $8.00 was paid.
- The 12 cents for each kWh up to 300 was paid.
Hence the intercept is given by:
b = 8 + 0.12 x 300 = 44.
The slope is the cost per kWh of 4 cents, hence the function is:
E(x) = 44 + 0.04x.

Answer:
the bigger rectangle = 30 x 5
Step-by-step explanation:
divide the bigger width by the smaller width to find the rate of change (2.5) and multiply both numbers (length and width) to get the larger rectangle.
