Note: All answers are on the upper right corner

For A: 1 is x, 3 is y, so what you do is go to 1 on the line where it goes from left to right and then go up 3 times.

For B: you go to 4 on the line that goes from left to right and go up 3 times.

For C: this is similar to A and B, you just find 4 on the line than go up 1 time.

Step-by-step explanation:

I really don't understand it that well but all that I can is that s can represent students that went on the trip, and each student's ticket cost is 20$, so 20*s=20s, but we are taking m as the total money collected, so we can end up saying that 20s=m, hope u understood :)

A prism is completely filled with 1120 cubes that have edge lengths of 12 in.

What is the volume of the prism?

Answers

Answer: if 1/2in then 140         if 12in then  1,935,360

Step-by-step explanation:    It's v=a^3, a being the length of a side. Since we know the length...

V=12^3, which equals 1728. So each cube has a volume of 1728 inches. Now, multiply that by 1120. You get...

1,935,360!  

Answer : 1120 x 12 = 13440

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?

Answers

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

Yes they do have enough

Key information - 180° - 82° = 98° (missing angle)

Equation - [tex](5y+12)=98[/tex] [tex]y=17.2[/tex]

Step-by-step explanation:

Let's solve for the missing angle first! 180° - 82° = 98°. 180 represents the total among the angles so we use 180 degrees.

then use the statement to solve for y and make it equal to 98°

[tex](5y+12)=98[/tex]

[tex](5y-12)[/tex]  = -12          subtract 12 from both sides

[tex](5y)[/tex]           =  86        Now solve for y by dividing 86 ÷ 5

y = 17.2                      

it would be obtuse!.

1/2(2x - 1) = -1/5 -3/5 find x

Answers

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
