simplify 25x² -30x +30x -36.
would it be 25x²-36, or 25x²+0x-36

Answer:

NO

Step-by-step explanation:

an equivalent ration to 2:3 would be 10:15. because when you simpliy 10:15 the most you can you would get 2:3. where as 10:18 is not equal

Yes they are equivalent

Answer:

To find 2/3 of an hour first we will divide 1 hour that is 60 minutes into 3 parts. So we will get 20 minutes. So we 2parts out of 3 parts of an hour so we get 20X2=40minutes

Answer:

0.9115

Step-by-step explanation:

Using a binomial probability function :

P(x =x) = nCx * p^x * (1 - p)^(n - r)

Probability of success, p = 0.55

1 - p = 1 - 0.55 = 0.45

n = 8

x = 2

P(x > 2 ) = p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7) + p(x =8)

To save computation time, we could use the binomial probability calculator :

P(x > 2 ) = 0.9115

Answer:

Step-by-step explanation:

1)

(x-3)/18=12/9, cross multiply

9(x-3)=18(12)

9x-27=216, add 27 to each side

9x=243, divide each side by 9

x=27

2)

(x-16)/(x+6)=3/5, cross multiply

5(x-16)=3(x+6)

5x-80=3x+18, subtract 3x from each side

2x-80=18, add 80 to each side

2x=98, divide each side by 2

x=49

3)

Since the triangles are similar we can say that

25/(4x-1)=10/(x+5), cross multiply

25(x+5)=10(4x-1)

25x+125=40x-10, subtract 40x from each side

-15x+125=-10, subtract 125 from each side

-15x=-135, divide each side by -15

x=9

here are the answers!

Step-by-step explanation:

A police officer can not punish air pollution but can enforce laws and regulations to protect the environment.

Air pollution means the presence of harmful substances in the air that can cause harm to all living beings.

We have,

Air pollution is not a living being so it can not be punished by a police officer.

A police officer or government authorities can enforce laws and regulations to reduce air pollution to protect all living beings and the environment.

Some of the measures are:

- Setting emissions standards for automobile and related industries

- Promoting the use of clean energy resources.

- Encouraging individuals and entities to adopt sustainable practices

Thus,

A police officer can not punish air pollution but can enforce laws and regulations to protect the environment.

Answer:

In the case of 4 tickets it can be possible

Step-by-step explanation:

Let us assume the number of tickets be t

Now as per the question the equations would be

For you  = t + $8

For your friend = t + $12

In the case when you both spend the same amount so the above equations would be equivalent to each other

t + $8 = t + $12

So here the tickets would be 4 so this is possible that you both spend the same amounts

Because the angles of a triangle add up to 180, you can just use subtraction to find out what the missing angle is.

9514 1404 393

Answer:

  ∠B = ∠C = 138°

  ∠D = 42°

Step-by-step explanation:

Angles between the parallel bases are supplementary:

  ∠B = 180° -∠A = 180° -42° = 138°

Right-side angles are the same measure as their mirrors across the line of symmetry.

  ∠C = ∠B = 138°

  ∠D = ∠A = 42°

Answer:

4 is the BASE and 5 is the EXPONENT

Step-by-step explanation:

Thx i needed this answer :P

The number 5 is the exponent or power and the number 4 is the base of the expression.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The exponential expression is given as,

⇒ (4)⁵

In the exponential expression aⁿ, the n is the exponent or power and a is the base of the expression.

Then in the exponential expression (4)⁵, the number 5 is the exponent or power and the number 4 is the base of the expression.

Answer:

D

Step-by-step explanation:

Given a quadratic function in standard form

f(x) = ax² + bx + c ( a ≠ 0 )

• If a > 0 then minimum value

• If a < 0 then minimum value

For

f(x) = x² + 16x + 3

a = 1 > 0 then f(x) has a minimum value

The minimum is the value of the y- coordinate of the vertex.

The x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

Here a = 1 and b = 16 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{16}{2}[/tex] = - 8

To find the y- coordinate of the vertex, substitute x = - 8 into f(x)

f(- 8) = (- 8)² + 16(- 8) + 3 = 64 - 128 + 3 = - 61

Thus the function has a minimum value of - 61 → D
