Radius of the circle is the length of rectangle divided by 2 (7cm)

Area of circle: pi*r²
Pi= 22/7

(22/7)*7²
=154

Since its a half circle, divide 154 by 2 =77

Area of rectangle:14*9=126

Subtract the circle from the rectangle: 126-77=49

The average price of a movie ticket in the United States from 1980 to 2000 can be modeled by the expression, 2.75+0.10x, where x

MissTica

Answer:

Step-by-step explanation:

step one:

Let the cost be y

to solve for the cost of a movie ticket, we need to solve the expression

y=2.75+0.10x

step two:

given that x is the number of years between 1980-2000

the number of years is 20years

put x= 20 in the expression for the cost we have

y=2.75+0.10(20)

y=2.7+2

y=$4.7
