if it costs 21.6$ for 12 brownies, how much would it cost for 1

Answer:

a) m + n + e3 + ( -2n)  +  10m  =  11m - n + e3

b) x + 2y -4y + 6x + 2x = 9x -2y

c) a + b + c + 2a + 3c -2a + 3b + 4c = a + 4b + 8c

d) 2a  -b + 3c -2a + 3b + 2c = 2b + 5c

Step-by-step explanation:

En cada uno de los casos:

1) Reorganizas los términos

2) sumas los coeficientes de los términos semejantes

a)  m + n + e3 + ( -2n)  +  10m

1) Reorganizando los términos

m + 10m + n + ( -2n)  + e3

2) Sumando los coeficientes de los términos semejantes

(1 + 10) m + (1 - 2) n + e3

(11)m + (-1)n + e3

11m - n + e3

b)  x + 2y - 4y + 6x + 2x

1) Reorganizando los términos

x + 6x +2x + 2y - 4y

2) Sumando los coeficientes de los términos semejantes

(1 +6 +2) x + (2- 4) y

(9) x + (-2)y

9x -2y

c)  a + b + c + 2a + 3c -2a + 3b + 4c

1) Reorganizando los términos

a + 2a - 2a  + b + 3b + c + 3c + 4c

2) Sumando los coeficientes de los términos semejantes

(1 + 2 - 2 ) a + (1  +3) b + ( 1 + 3 +4) c

(1) a + (4)b + (8)c

a +4b + 8c

d)  2a -b + 3c -2a + 3b + 2c

1) Reorganizando los términos

2a - 2a - b + 3b + 3c +2c

2) Sumando los coeficientes de los términos semejantes

(2 - 2) a + (-1 +3) b + (3 +2)c

(0) a + (2) b + (5) c

2b + 5c

Answer:

The answer is 25.125

Step-by-step explanation:

The answer would be 25.125 cubic inches because if you take the volume of a cube that has one side of 3.5 just multiply 3.5x3.5x3.5. This would give you 42.875. Then you have the area of a base which is already squared and you would multiply that with 4.25 to get 68 in cubed. You then know that 42.875 is the volume of the speaker and you are putting it in the box that has a volume of 68. To find what volume is left, you would subtract 42.875 from 68 to get 25.125 in cubed.

Answer:

72 pancakes

Step-by-step explanation:

The question basically asks you to:

Find 75% of 96

We can do this, by competing:

[tex]\frac{75}{100}[/tex] x 96 = [tex]\frac{3}{4}[/tex] x 96 = 3 x 24 = 72

Hope this helps.

Answer:

(1/3) Pi r^2 h

Step-by-step explanation:

The volume of a cone (or pyramid, for that matter) is 1/3 the area of the base times the height.

Cones have bases that are circles, so their areas are Pi r^2, usually written [tex]\pi r^2[/tex], Pi times the radius squared.

[tex]V=\frac{1}{3}\pi r^2h[/tex]

Answer:

Answer:

  False

Step-by-step explanation:

Corresponding angles in similar triangles are congruent. The similarity statement tells you angle B corresponds to angle Y, so those angles are congruent. The sines of congruent angles are identical.

  sin(B) > sin(Y) . . . . FALSE

  sin(B) = sin(Y) . . . . true

Answer:

The answer is true.

Answer:

i got 32square feet (yes i got it right).

Step-by-step explanation:

The amount of sand will there after the flower bed is installed is,

⇒ 18.5 feet²

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

At schools art teacher designs a circular flower bed inside a rectangular sandbox.

Here, We have;

The sandbox is 6 feet wide and 10 feet long.

Now, We get;

⇒ Radius of circle = 5 feet

Hence, Area of circle = πr²

⇒ Area of circle = 3.14 × 5²

⇒ Area of circle = 78.5 cm²

And, Area of rectangular sandbox is,

⇒ 10 × 6

⇒ 60 feet²

Thus, There will be after the flower bed is installed = 78.5 - 60

                                                                               = 18.5 feet²

Answer:

x < -15*C (I can’t make the degrees sign on my iPad, so I put * instead).

3 Possible Answers:

-38*C

-26*C

-57*C

Step-by-step explanation:

Inequality:

x = temperature

< = less than

-15*C = the amount the temperature was less than

3 Possible Outcomes:

Because the temperature is less than -15*C, it can literally be any number that is farther down the number line. Because it’s a negative number, anything like -14, -13, -12, and so on would actually have a greater value (think of it as in being less in debtm or in this case, less below zero). Instead, you’ll do any number like -16, -17, -18, and so on. You can even do a decimal number, like -19.5. I hope this makes sense to you!

Answer:

Answer:

Rule: replace x by x - a where a is the number of units that you want to move right. a must be greater than 0. x - - a  would move left.

Step-by-step explanation:

You want f(x) to move 3 units to the right.

That would mean that  x would be replaced by x - 3.  Just to be sure let's try it.

Answer: g(x) = (x+3)^2

The answer should be in the form of a(x-h)2 + k.

Since we are not translating up or down, the k value is 0. We will not be adding any values to the outputs of the original equation here. a will equal 1 since no stretches are occurring. So we are left with the h value.

f(x) = x2 is given.

g(x) = a horizontal translation of 3 units left. This means that the h value is -3, because in order to move left, you need to take 3 away from all x values (inputs). So the point (2,4) on f(x) would become (-1,4) on g(x).

How do we write this?

g(x) = f(x-h) where h = -3.

So this is g(x) = f(x - (-3)) = f(x+3)

g(x) = (x+3)^2

4600 is the answer to this

The solution is, the following statement is, False.

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

here, we have,

given that,

Triangle ABC is similar to triangle WYZ.

now, we get,

Corresponding angles in similar triangles are congruent.

The similarity statement tells you angle B corresponds to angle Y,

so those angles are congruent.

The sines of congruent angles are identical.

so, we have,

 sin(B) > sin(Y) . . . . FALSE

 sin(B) = sin(Y) . . . . true

Hence, The solution is, the following statement is, False.
