Answer:
(n-2)180
Step-by-step explanation:
Let us assume the number of sides is 'n'.
So,
The SUM of the interior angles of a shape with n sides is given by the formula (n-2)180
Answer:
I believe your answer is 92.
Step-by-step explanation: Usually, a picture frame is in the shape of a square or rectangle. So to find area you use length times width, correct? Since the opposite side of each side on a rectangle or square is the same value, then that means your answer is probably double that of the area. Giving you 92 :) I hope this helped a bit!
He will have to pay $3.25.
Let the number of miles traveled by a driver be x
The toll paid by the driver is then represented as $y.
Since there is a linear relation between the two, we can assume the equation can be written as:
y = mx + c
From the given data, we get
0.24 = m(0) + c
c = 0.25
Using the second point:
1 = m(1) + 0.25
m = 1 − 0.25 = 0.75
Hence, the equation is y = 0.75x + 0.25.
If x = 4, then:
y = 0.75 × 4 + 0.25
y = $5.50
Hence, He will have to pay $3.25.

Answer:
0.18
Step-by-step explanation:
Given that:
P₁ = $10, P₂ = $20
From the tables Q₁ = 900, Q₂ = 800
Using midpoint method:
Percentage change in quantity = 
Percentage change in price =
Price of elastic demand = Percentage change in quantity/ Percentage change in price = -11.76% / 66.67% = 0.18
The Price of elastic demand is positive because we took the absolute value and elasticity are always positive
Therefore since Price of elastic demand < 1, the demand is inelastic in this interval.
This means that, along the demand curve between $10 to $20, if the price changes by 1%, the quantity demanded will change by 0.18%. A change in the price will result in a smaller percentage change in the quantity demanded. For example, a 10% increase in the price will result in only a 1.8% decrease in quantity demanded and a 10% decrease in the price will result in only a 1.8% increase in the quantity demanded
