Answer:

12/13 or 92.31%

Step-by-step explanation:

Answer:

48%

Step-by-step explanation:

So, we have to find what percentage is 12 out of the whole thing so:

We add the boys and the girls together to get the whole thing:

12 + 13 = 25

Then we turn it into a fraction:

12/25 = 48/100

So, 48% of the class is boys

Answer:

The 7th term of the sequence is 0.000768

Step-by-step explanation:

As given, the sequence is : 12, -2.4 , 0.48, ....

The first term = 12

Second term = -2.4

Third term = 0.48

Common ratio = [tex]\frac{-2.4}{12} = \frac{0.48}{-2.4} = -0.2[/tex]

Fourth term = 0.48(-0.2) = -0.096

Fifth term = -0.096(-0.2) = 0.0192

Sixth term = 0.0192(-0.2) = -0.00384

Seventh term = -0.00384(-0.2) = 0.000768

Answer:

a/3b^2

Step-by-step explanation:

16a^2b^3c^6/48ab^5c^6

the c^6 cancel out, then simplify a^2 and a: ​16a^2b^3/48ab^5 = ​16ab^3/48b^5

Then divide 48 and 16 you get 3 ​16ab^3/48b^5 = ab^3/3b^5

And lastly, simplify b^3 and b^5  ab^3/3b^5 =

a/3b^2

Answer:

y= -4x^2 + 15x - 14

Step-by-step explanation:

A parabola is always in the form y = ax^2 + bx + c.

Substitute each point to produce different equations:

-14 = 0a + 0b + c = c

so c = -14

-3 = a1^2 + b1 + c = a + b - 14

so a + b = 11

0 = a2^2 + b2 + c = 4a + 2b -14 = 0

so 4a + 2b = 14

if we double a + b = 11 we get 2a + 2b = 22

Subtract this from 4a + 2b = 14 and we get 2a = -8 so a= -4 and b = 11 - a = 15

We don't need to use the (3,5) points as we have all the information we need.

Answer:

Your answer is: (-1/2, 3/2)

Step-by-step explanation:

y = x + 2

y = -3x

Use substitution by plugging the second equation into the first.

-3x = x +2

Subtract x from both sides to combine the variables.

-4x = 2

Divide both sides by -4 to isolate the variable x.

x = 2/-4

Simplify.

x = -1/2

Plug x into one of the equations to find y.

y = (-1/2) + 2

y = 3/2

Plug x into the other equation to confirm your answer.

y = -3(-1/2)

y = 3/2

Your answer is: (-1/2, 3/2)

Answer:

d.(-1,4)

Step-by-step explanation:

Option D is correct, the coordinates of the image D are (-1, 4)

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

To find the coordinates of the image D, we need to apply the dilation transformation centered at R(-3, 5). Let the scale factor be k.

The x-coordinate of D will be shifted k times the distance between 1 and -3, which is 4 units, from the x-coordinate of R, which is -3. So we have:

0.5 = -3 + k(4)

Solving for k, we get:

k = 1.375

Similarly, the y-coordinate of D will be shifted k times the distance between 3 and 5, which is 2 units, from the y-coordinate of R, which is 5. So we have

R: (x, y) = (-3, 5)

D: (x, y) = (-3 + 1.375(1 - (-3)), 5 + 1.375(3 - 5))

D: (x, y) = (-1, 4)

Therefore, the coordinates of the image D are (-1, 4), which is option D.

Answer:

[tex]x=2\sqrt{2}[/tex], [tex]x=-2\sqrt{2}[/tex], [tex]x=4i[/tex], [tex]x=-4i[/tex]

Step-by-step explanation:

[tex]x^4+11x^2=3x^2+128[/tex]

First, we subtract 128 from both sides:

[tex]x^4+11x^2-128=3x^2[/tex]

Then, we subtract [tex]3x^2[/tex] from both sides:

[tex]x^4+8x^2-128=0[/tex]

Rewrite the equation:

[tex]u^2+8u-128=0[/tex]

Insert and solve:

[tex]u^2+8u-128=0\\u=8,u=-16\\x^2=8:x=2\sqrt{2},x= -2\sqrt{2} \\x^2=-16:x=4i,x=-4i[/tex]

Answer:

Part A: If Beatrice inputs −8 into the function, she must get an output of 8.

Part B: (−4,8) , (4,−8) , (8,−4)

Step-by-step explanation:

Part A:

We know that a function is a relation that maps elements from one set (The domain, the set of the inputs) into elements from another set (the range, the set of the outputs)

Such that each input can be mapped into only one output.

Then if we know that our function maps the input -8 into the output 8.

Always that we use this function with the input -8. we will have the same output, 8.

Then we can conclude that the correct option to the first part is:

"If Beatrice inputs −8 into the function, she must get an output of 8. "

Part B:

Remember, -8 is mapped into 8, then the point (−8,4) (this says "-8 is mapped into 4) can never be on the graph of the function.

But the points:

(−4,8) , (4,−8) , (8,−4)

Could be on the graph of the function.

Answer:

correct A:-8,8

B: -4,8

==============================================================

Work Shown:

x = side length = 1 unit

SA = surface area of cube

SA = 6x^2

SA = 6*1^2

SA = 6*1

SA = 6

The surface area of the cube is 6 square units.

-------------------------

Side note:

In general, each face is x*x = x^2 units in area, and there are 6 of those faces. This is why the general surface area is 6x^2. In this case, each face is 1 square unit, so all 6 faces lead to a total of 6 square units.

Answer:

the answer is a = -4

Step-by-step explanation:

pls mark brainliest

Answer:

a = -4

Step-by-step explanation:

To find a, we need to get the variable on one side of the equation. So first we distribute.

-3a+5=a-6a-3 Now we subtract 5 from both sides and add the a to the -6a

-3a=-5a-8 Now we add 5a to both sides

2a=-8 And lastly divide both sides by 2

a= - 4

Answer:

3.9 that's how much he had

Answer:

He had $3.90 at the start of his walk.

Step-by-step explanation:

To find out how much money he had before his walk, you would take 2.55 + 1.35 and that you give you 3.9. But since we are dealing with money, you need to have the 0 at the end. So he started with $3.90 when he started his walk.
