Answer:
Step-by-step explanation:
Let width = w units
Length = 4w - 3
Cost for lining corners of wall = $ 18.50
Perimeter of the wall = 18.50/0.25 = 74 ft
2*(length +width ) = 74
2*(4w - 3 + w) =74
2*(5w - 3) =74
10w - 6 = 74 {Add 6 to both sides}
10w - 6 + 6 = 74 + 6
10w = 80
Divide both sides by 10
10w/10 = 80/10
w = 8 ft
Length = 4w - 3 = 4*8 - 3 = 32 - 3
Length = 29 ft
Area of the wall = length * width
= 29 * 8
= 232 square ft
Cost of painting the wall per square feet = 20 cents = 0.20
Cost of painting 232 square feet = 232 * 0.20
= $ 46.40

C=2pir
r=9
c=2pi9
c=18pi
if we aprox pi=3.141592
c=56.54865 inches
Answer:
<em><u>AT</u></em><em><u> </u></em><em><u>LEAST</u></em><em><u> </u></em><em><u>40</u></em><em><u> </u></em><em><u>STUDENTS</u></em><em><u> </u></em>
Step-by-step explanation:
first make an expression to represent the zoo and museum cost.
( x represents the number of students)
zoo: 10x +100
museum: 5x+250
second plug in numbers of students until you find the answer: <em><u>at</u></em><em><u> </u></em><em><u>least</u></em><em><u> </u></em><em><u>40</u></em><em><u> </u></em><em><u>students</u></em><em><u> </u></em>
