Answer:
s= students m= money ($20) equation_ s*m= total
Step-by-step explanation:
I'm not entirely sure on specifics, such as how man students. so, I can't pinpoint an exact total. I hope this helps though

The set designers of a school play need to determine the cost of the gold paper they’ll need to create stars in the shape of the shaded region in the figure below.
The gold paper is being sold at Michaels for $2.45 per square centimeter.
The set designers have a $6,000 budget to make these stars. Do they have enough money to make 50 stars?
Answer: Yes, they do.
Step-by-step explanation: You have to calculate the area of the star; you do this by calculating the area of the square and subtracting the area of the unshaded parts, which is a quarter of a circle.
Therefore,
15^2 - pi * 7.5^2 = 48.28541324 cm squared
Multiply this answer by $2.45 for one star:
Equals $118.2992624
Multiply by 50,
Equals $5,914.96
Since this is less than $6,000 they have enough money to make 50 stars

1/2(2x - 1) = -1/5 -3/5 find x
Answer:
x = -3/10
Step-by-step explanation:
1/2(2x - 1) = -1/5 -3/5
Combine like terms
1/2(2x - 1) = -4/5
Multiply each side by 2
2* 1/2(2x - 1) = -4/5*2
2x-1 = -8/5
Add 1 to each side
2x-1+1 = -8/5 +1
2x = -8/5+5/5
2x = -3/5
Divide by 2
2x/2 = -3/5 * 1/2
x = -3/10

Answer:
1) 128/225
2)1 7/60
Step-by-step explanation:
1)
(3/5+1/9)x4/5
32/45x4/5
128/225
2)
2/3+1/5+1/4
13/15+1/4
1 7/60
1. Answer:
128/225
Step-by-step explanation:
Find the lest common denominator for 3/5 + 1/9 which is 45. 3/5 times 9, 1/9 times 5. So, then you have 27/45 + 5/45 = 32/45. So, then you do 32/45 times 4/5. 45 times 5 is 225. 32 times 4 is 128.
2. Answer:
1 7/60
Step-by-step explanation:
LCD for 3,5,4=60. 3 times 20 = 60. 5 times 12 equals 60. 4 times 15 equals 60.
So, then do 2 times 20 equals 40. 1 times 12 equals 12. 1 times 15 equals 15.
[tex]\frac{40}{60}+\frac{12}{60}+\frac{15}{60}[/tex] = [tex]\frac{67}{60} = 1 \frac{7}{60}[/tex]

After reading a book about ancient Egypt, Cassie decided to build a model of a pyramid out of cardboard
How much cardboard does Cassie need to make the model, including the bottom?
Answer: 2125 cm^2
Step-by-step explanation:
We will need to find the surface area of the pyramid:
SA = (1/2)Pl(slanted height) + b
SA = (1/2)(25*4)(30) + 25^2
SA = 1500 + 25^2
SA = 2125 cm^2
