Answer:

y=15x+25, the cost is 205 dollars

Step-by-step explanation:

The simplest way to write a rule for this is to write it in slope intercept form, y=mx+b. Let y represent the cost of the membership. Every month the cost is 15 dollars. If we let x represent the months we can rewrite this as 15x. The one time cost is 25 dollars so we can just add that to the end of the equation. y=15x+25. There are 12 months in a year so we just have to substitute. y=15(20)+25=205 so the answer is 205 dollars.

Answer:

186 cm²

Step-by-step explanation:

*First we can move the shape around a bit to make it simpler to solve. If we take the triangle from the left side and move it over to the right, it connects with the other piece to create a rectangle. This leave two rectangles total which is much easier to solve.

*To find the length of the right rectangle, you take the 22 cm at the bottom and subtract the 12 cm (which is being used as the length for the left rectangle). This will give you a length of 10 cm long.

Left rectangle:

A = lh

A = 12 (8)

A = 96 cm²

Right rectangle:

A = lh

A = 10 (9)

A = 90 cm²

Total:

A = 90 + 96

A = 186 cm²

Answer:

The 3rd semi-circle equals 31.

Step-by-step explanation:

Since the Pythagorean Theorem states that "The sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c)," we can find the answer of the 3rd semi-circle by finding the sum of each of the 2 smaller semi-circles and adding them together.

Answer:

8

Step-by-step explanation:

You multiply the candies sold, by 8 to get the money raised.

10 times 8 is 80.

20 times 8 is 160

30 times 8 is 240

And so on.

I hope this helps!

pls ❤ and give brainliest pls

Divide money raised by candles sold:

80/10 = 8

160/20 = 8

Etc.

Each candle cost $8

You would multiply the number of candles sold by $8 to find the amount of money raised.

Answer:

1) 12

2) 72

Step-by-step explanation:

1) The GCF of 36 and 24 is 12. So, each child would get 3 prizes and 2 balloons.

2) The LCM of 18 and 24 is 72. When the first radio station is playing the song for the fourth time, the second radio station will play the song for the third time. This will happen 72 minutes after they both play it for the first time.

Answer:

1. 12 children

2. 72 minutes

Step-by-step explanation:

1. Find the GCF of 36 and 24, which is 12

2. Find the LCM of 18 and 24, which is 72

Answer:

4(3y+4)

Step-by-step explanation:

12y + 16

4*3*y +4*4

Factor out 4

4(3y+4)

Answer:

2(6y+80) = 12y+160

4(3y+4) = 12y+16

28y = 28y

16+12y = 12y+16 (did not use distributive property)

So,  B is correct.

Let me know if this helps!

Answer:

Sandwiches and hot dogs are almost equally preferred.

Step-by-step explanation:

When looking at the data, the number of students who chose sandwiches and the number of students in which who chose hot dogs is 1 off and so they are almost equally preferred.

Answer:

Step-by-step explanation:

a) 4x¹⁰ = 2² * x¹⁰

   64x² = 2⁶ *x²

GCF = 2² * x² = 4x²

b) 4x¹⁰ - 64x² = 4x²*(x⁸ - 16)

                  =4x² *[ (x⁴)² - 4²]

                  = 4x² * (x⁴ + 4) (x⁴ - 4)

                  = 4x² * (x⁴ + 4)* [(x²)²- 2²]

                  =4x² * (x⁴ + 4) * (x² + 2)(x² - 2)

C) 360

Step-by-step explanation:

Volume = length x width x height

Volume = 3/2 x 1/4 x 5/3

3/2 x 1/4 = 3/8

3/8 x 5/3 = 15/24

Volume = 15/24 cm^3

Answer: 15/24

Final Answer: 277 people had scarves.

Step-by-step explanation:

1824 / 2 =  912 (Divide by 2 to get the people wearing hats)

912 / 3 = 304 (subtract 304 to get 2/3)

912-304 = 608

608/4 = 152. (people who wore gloves, hats, and scarves.)

152+100+25= 277

Answer:

x = 1.4 or -1.4

Step-by-step explanation:

→ Substitute y = 4 into y = x² + 2

4 = x² + 2

→ Minus 2 from both sides

2 = x²

→ Square root both sides

√2 = x

→ Simplify

x = 1.4 or -1.4

Answer:

You can check if an equation is true for all some or no values of x by simply to  try and solve the equation if you get something like x = x, then the equation  is true for all, if you get a specific answer like x=3, then it is true to some values, in simple terms. Try and solve the equation there is no other way to check unless you solve, I don't know if there is another way but this is just my intution.

Step-by-step explanation:

Beacuse ‍♀️

Answer:

This is a rectangle, so if AB is equal to 3 centimeters, then DC is equal to 3 centimeters.

Since Angle X is equal to 45 degrees, then angle CDE, is also equal to 45 degrees, and we have an isosceles triangle, since angle  CDE and DEC are equal to each other.

This means, that CE = DC.

And because E is the midpoint of CB, CE = EB.

So basically, we have:

DC = CE = BE

DC = 3

3 = CE = BE

And we see that CE and BE are both equal to 3, which makes CB equal to 6, which makes solving the area easy. (3 x 6), which is 18.

B is correct!
