The admission fee at a fair is $2.00 for children and $4.00
for adults.
On Saturday 2,500 people entered the fair and $7,000.00 were
collected.
How many children and how many adults attended? Give your
answer, using x for children, y for adults.
Form of: x =, and y =
Let K = no. of children
Let A = no. of adults
2500 people mean
Kids + Adults
K + A = 2500
K = 2500 – A
2K + 4A = 7000
K + 2A = 3500
(2500 – A) + 2A = 3500
A = 3500 – 2500
(A = 1000, adults)
K = 2500 – A
K = 2500 -1000
(K = 1500, Kids)
CHECK:
1500*2 = $3000
1000*4 = $4000
<span>(Total = $7000, people.). </span>

Formula for the area of a circle: A = pi * r^2
A semi-circle is half of a circle. So, we will need to divide the area of the total circle by 2 to find the area of a semi-circle.
r = d / 2
r = 6 / 2 = 3
A = pi * 9
A = 9pi
Semi-circle:
A = 9pi / 2
A = 4.5 pi cm^2 or 14.14 cm^2
Hope this helps!! :)
Answer:
i dont know i swear
Step-by-step explanation:
To find the unit rate you would need to find the cost per ounce of potato chips. To find this you would simply divide. $3.80/20 = .19
So the unit rate in your question is $0.19
Hope this helps! :)
Rectangle ABCD is one of the figures.
There is a circle where the line AD forms the radius.
Total area of rectangle = 18
Line AB = 6
So, line AD = 3 and line AE = 3
The interior angles of a rectangle are 90 degrees.
270 : 360 = x : (2*pi*r)
270/360 = x/(2*pi*3)
3/4 = x/(6 pi)
4x = 3* (6 pi)
<span>x = 9pi / 2
The length of the major arc AE is 9pi / 2</span>
